The Complete Beginners Guide to Water Filters

The perfect guide for anyone trying to wade through the process of buying a water filter. This guide has everything you need to know. Click to read more or PIN to save for later.

If you’re like most people, you want to drink clean water but aren’t sure where to start. Or, perhaps you’ve looked into all the different types of water filters and found yourself totally confused. There’s a good reason for this! The information available is complex, sometimes misleading or conflicting and there’s so much to digest. Until now.

You don’t need to become a water quality expert to choose the best water filter. We’ve put together the basics on what you need to know.

Welcome to the Complete Beginners Water Filter Guide. You’ll learn why it’s important to drink filtered water, important considerations for choosing a water filter, and our top picks in our 2016 Water Filter Guide.

In this Guide, we’ll cover the following:

Let’s start with why it’s important to drink filtered water.

Tap Water Contaminants – It’s a Long List


If you think about it, your water department has a big job. Hundreds of contaminants end up in your water supply including:

  • Agriculture pesticides & fertilizers
  • Industrial pollutants
  • Urban runoff chemicals
    • Car emissions
    • Road surfaces
    • Pharmaceuticals
    • Personal Care Products
    • Flame Retardants
  • Water treatment chemicals & their byproducts

It’s an overwhelming list especially since well-respected research has linked many of these contaminants to cancer, liver, kidney and nervous system problems.

So, it’s important to understand some of the shortcomings in the system that provides your drinking water. Here are our top 5 concerns about tap water and why it’s important to use water filters.


1. EPA Standards aren’t Stringent Enough


Did you know that the EPA sets two levels for water departments?

You are probably wondering how this works.

The EPA sets two measures; one standard is enforceable while the other is not.

  • The unenforceable standard is the Maximum Contaminant Level Goal (MCLG). The EPA sets the MCLG at a level where they expect no adverse health effects
  • The enforceable standard is simply called the Maximum Contaminant Level (MCL) – this is often set higher than the goal

Think of the MCLG as considering your health and the MCL as considering your health and the costs of removing contaminants.

As a result, your tap water may have unhealthy levels of contaminants (exceeding MCLG), but still be meeting the enforceable standards (meeting MCL).

It’s a troubling thought, isn’t it?

Your water is not meeting the EPA experts’ standards for good health because the EPA also factored in the cost of meeting those safety levels.

To get an understanding of how this works, consider arsenic standards. The EPA classifies arsenic as a known human carcinogen. Its MCLG is 0.00 meaning that to avoid any adverse health effects, water should not contain any arsenic. However, arsenic’s MCL or enforceable level is 0.01 which allows water supplies to contain arsenic and meet standards.

You’re probably not on board with drinking arsenic–didn’t think so.


2. The EPA doesn’t Regulate ALL Pollutants (Not Even Close)


The EPA does not regulate all pollutants. In fact, a 2009 study detected 316 contaminants and a whopping 202 of those contaminants had no safety standards. About 132 million people in the US had unregulated pollutants in their tap water according to the study.

Admit it. You’d rather have safety standards for more contaminants.

You’d like to think that the EPA has selected the most dangerous contaminants to regulate, but there’s a constant stream of new chemicals being developed and an understaffed/underfunded agency trying to keep up.

The EPA is only regulating 1/3 of contaminants. Does that seem like enough to you?


3. Your Water Department isn’t Perfect


It’s possible that your water department is failing on certain regulatory standards.

People make mistakes. Processes fail. Equipment malfunctions. When these mistakes occur, they can negatively affect many people.

For example, from 2004-2009, the Environmental Working Group reports that water departments serving 53 million people failed to meet the goal for Trihalomethanes, a likely carcinogen, according to the EPA.

That’s a lot of imperfection.


4. Bad Stuff Can Happen Between the Water Plant and your Sink


Your water gathers contaminants between the water plant and your house, so even if you’re convinced that your water department is doing a perfect job, your tap water can be contaminated by the pipes that lead to your house or the pipes inside your home. This is precisely what happened in Flint MI and many other cities as well. Lead leached from the pipes and contaminated the water.

Five Things You Don't Want to Hear About Tap Water

You may think that lead pipes are a thing of the past. It’s true that lead water pipes are no longer used today, but many older lead pipes are still in service. And during a repair or change in water chemistry, these pipes can leach lead into tap water.

And, it’s not just lead that could be a problem. Other contaminants can end up in your drinking water as well.

So, as your tap water travels from your water treatment plant into your house, it can pick up contaminants along the way causing unsafe levels of lead and other contaminants.


5. Fluoride Levels May Exceed Healthy Levels


Tap water contains fluoride which can cause adverse health effects. A 2006 study of Fluoride in Drinking Water sponsored by the EPA recommended lowering the MCLG due to concerns about increased bone fracture rates and enamel fluorosis in children 0-8 years old. The committee unanimously recommended that the EPA set fluoride levels lower due to strong health concerns.

The committee also recommended further study about fluoride’s impact on thyroid and brain functioning.

Unfortunately, the MCL and MCLG are still set at 4 mg/L, an unsafe level according to the committee. For a full copy of the report, click here.

Seems hard to believe, right?

A huge study conducted by experts says that the fluoride goal is too high. And, ten years later, the goal still hasn’t been reset?


What Type of Water Filter is Best for You?


Now that you’ve learned about the EPA’s two standards, the burgeoning number of new, unregulated chemicals, the fallibility of your water department, the possibility of unsafe water pipe infrastructure, and the potential of having more fluoride in your water than is healthy, what’s next?

Well, you probably want to know how to get drinking water that you can trust. This next section explains the basics of water filter systems. The last section of the Water Filter Guide provides recommendations.

Water Filter Systems Basics

Almost all drinking water filters use some form of carbon filtration while the best and most effective purifiers use more than one type of filtration media. Why would products have more than one filter type? Because different filter types are effective at removing different types of contaminants.

The most common types of media are carbon and/or activated carbon, ceramic filters, metallic alloy, carbon block resin, and reverse osmosis membranes. Each filter medium has its strengths and weaknesses. For example, carbon filters are excellent at removing a broad range of contaminants but are completely ineffective at removing contaminants like Fluoride.

Water Purifier Product Types Explained – Gravity, Faucet, Counter Top, Under Counter & Whole House

There are many types of water purifiers to choose from. Let’s start with the Point of Use (POU) filter types. The simplest POU filters are Gravity-fed Pitchers or larger dispensers that you fill manually.

Then there are Faucet Filters that attach to your water spout and Counter Top Filters with a free-standing water filter unit that sits next to your sink and attaches to the end of your faucet via hoses. Both faucet and counter top filters have a diverter valve that engages the filter when you want filtered water. All of these filters are easy DIY solutions.

The next level in terms of installation difficulty is Under Counter Filters. These filters attach to your cold water line and provide filtered water to a separate, dedicated drinking water faucet (included with your filter). Under Counter Filters come with and without Reverse Osmosis (RO) filters. The RO filters need a separate holding tank for filtered water as well as a connection to your water waste line. These systems can either be installed by a handy homeowner, or by a plumber. Keep in mind that when you install a separate water faucet, you’ll need a hole cut in your countertop. A plumber can handle this for you.

A Point of Entry (POE) or Whole House System connects directly to your incoming water line and filters all the water to your home. A Whole House Filters has a high water flow rate, so it can’t filter out as many contaminants as a POU system. You’ll need a licensed plumber to install your Whole House Filter.

If you install a Whole House System, you’ll still need drinking water filter. Read How to Select a Whole House Filter for more information on why you need two systems.

Determining Effectiveness

How do you know which products are effective? The American National Standards Institute (ANSI) with the National Science Foundation (NSF) have contaminant reduction standards for drinking water treatment units. When buying your filter, look for these NSF standards:

    • NSF Standard 42-Aesthetic Effects. This standard covers Chlorine, Taste and Odor, and Particulates.
    • NSF Standard 53-Health Effects. This standard applies to hazardous contaminants including microbiological (harmful cysts), chemical (disinfection byproducts, pesticides and herbicides, VOC’s, and MTBE’s), and particulate matter (lead, mercury, etc.).
    • NSF Standard 58-Reverse Osmosis. This standard applies only to RO systems and addresses Total Dissolved Solids (TDS) and other hazardous contaminants.
    • NSF Standard 401-Emerging Compounds/Incidental Contaminants. This standard covers up to 15 contaminants found at trace levels in public drinking water. These include certain prescription drugs as well as over the counter pain medications, pesticides, and herbicides not before targeted, and some new chemical compounds used in flame retardants, plastics, and detergents. All good things to remove from your drinking water!

It is important to note that although these standards cover many contaminants and set up MINIMUM reduction requirements, a product does not have to remove ALL of the contaminants to earn NSF certification. The filter only has to reach the minimum requirement for the contaminants claimed by the manufacturer to receive certification.

You Must Read the Fine Print, Really!

To compare filters you have to look not only for the NSF certification, but you need to check each filter’s Performance Data Sheet to find (1) the number of contaminants removed, and (2) the real level of reduction achieved. So while it is true that ALL CERTIFIED products meet minimum reduction requirements, some will perform better than others at removing contaminants.

This is where we come in.

We can help you make the best choices for you and your family. We’ve already read the performance results and performed the side by side comparisons, so you don’t have to. All you need to know is that all products that are certified to an NSF standard are not created equal, so you aren’t confused by marketing claims. Our Water Filter Guide will make your decisions much easier!

Choosing the Right Filtration Product Type For You

How do you choose the right type of filter? Here’s a quick outline of the options.

Pitchers and Gravity Fed Dispensers:

These filters are not connected to your plumbing, are free-standing and portable.
Pluses:

  • Easy set-up and operation, no installation necessary
  • Great to use at the office, in dorm rooms or in temporary living situations

Minuses:

  • Only filters small amounts at a time
  • Performance varies widely among pitchers; name brand pitchers only filter a handful of contaminants. However, we did find one brand that filtered as well as an installed water filter system.

Faucet Filters:

Faucet filters attach to the end of a standard kitchen or bathroom faucet and use a diverter for filtered water.
Pluses:

  • Easy to install and move, good for renters
  • Low cost

Minuses:

  • Will not work with many specialty faucets such as pull-out sprayers
  • Limited contaminant reduction; all the faucet filters we researched had the same limited performance much like the big name water pitcher filters

Counter Top:

These filters sit on the counter next to the kitchen or bathroom sink and connect via a small hose to the faucet.
Pluses:

  • Easy to install and move, good for renters
  • Easiest way to install a high capability filter

Minuses:

  • Aesthetics may not appeal to everyone
  • Will not work with many specialty faucets such as pull-out sprayers

Under the Counter Filters:

These are plumbed-in systems that connect to your cold water line under your sink and dispense filtered water through a second small faucet rather than the main faucet. You can install yours at your main kitchen sink or at a secondary sink like a wet bar.
Pluses:

  • High capability filter, installs under the sink and out-of-the-way
  • Dedicated drinking water faucet

Minuses:

  • Requires space under the kitchen sink
  • Requires a plumber or someone with basic plumbing skills to install

Reverse Osmosis Filters:

These are plumbed-in systems that connect to your cold water line and dispense filtered water through a second small faucet rather than the main faucet. Can be located at the main kitchen sink or at a secondary sink like a wet bar. Requires more space than just an under the counter filter to accommodate a separate filtered water holding tank.
Pluses:

  • High degree of filtration
  • Dedicated drinking water faucet

Minuses:

  • Cost – more expensive than other water filter systems
  • Space requirement due to separate holding tank

Whole House

These are systems that are plumbed-in through your main water line to reduce chlorine. With the addition of a water softening component, they will also reduce barium and radium typically.
Pluses:

  • Filters all the water coming into your house
  • Can soften hard water

Minuses:

  • Requires a plumber
  • Very limited capacity to remove other contaminants so a drinking water filter solution is typically needed/required

The Best Way to Remove Fluoride and Pesticides from Tap Water

Want to remove fluoride? You've got 3 great options. Get the details by clicking to read the article or PIN to save for later.

One of our readers asked about a Fluoride Water Filter. She also wanted this filter to remove pesticides.

“I’m trying to upgrade from our Pur faucet mount and want to remove fluoride from our water with a new filter. But your app [Pure Living Space Water Filter Selector App] is pointing me to reverse osmosis, which I’ve read wastes a ton of water, so I’d like to find an alternative. We’re in farm country, so I want to be sure our filter takes out pesticides. Undersink is preferable, but we’ll do counter if it seems a better choice. I’m also interested in seeing the costs for replacement filters and how many gallons they’re good for. Thanks for your help! S.S.”

Best Way to Remove Fluoride & Pesticides from Drinking Water


Here’s our response about how to find and select the best fluoride water filter.

As you probably know, Fluoride is among a group of contaminants that is difficult to remove. Most water filters do not remove Fluoride. In fact, most water filters, especially the name brand water pitchers, only remove a handful of contaminants. If you want to drink the cleanest water, you need to look beyond the big box store brands.

Let’s take a look at several good options to remove fluoride and pesticides.


Reverse Osmosis (RO) and Carbon Water Filter System


Your first option is the Aquasana Reverse Osmosis & Carbon Filter system. A carbon filter alone will not remove fluoride and some other tough to remove contaminants, so you need the RO filter as well. We use this Aquasana system in our home. It’s one of the few that has three NSF certifications.

You may have read on our website that we only recommend water filters that have been tested by a certified third-party lab. This RO and Carbon Water Filter System passes that test with high marks. Remember to always read and compare the test results because even certified water filters perform at different levels.

The Aquasana RO system’s performance is impressive in terms of the % of contaminants removed, especially the % of fluoride it reduces. It compares favorably to other systems that may only reduce 50-70%. See the test results for this Aquasana water filter system.

It’s true that an RO system does waste some water, the equivalent of a couple of extra toilet flushes a day. The other concern many people raise is that an RO system strips out the good water minerals. However, with the Aquasana RO system, it has an added feature that remineralizes your water making that issue less of a concern to most people.

The annual cost of maintaining the RO system averages $177.


Propur Container Filters Remove Fluoride


Since you’re concerned about wasted water, you could choose one of the Propur container filters. These containers sit on your counter top. Just like a water filter pitcher, you fill the container with water and let gravity pull the water through the filter. The Propur container filters come in a variety of sizes from the Propur Water Pitcher Filter to the Propur Stainless Steel Water Filter Containers that range from 55 oz. to 4 gallons.

This is the only proven gravity filter we found that removes fluoride. Although Propur doesn’t have NSF certification, Propur’s filters were tested by a certified lab. They share their results on their site–not all water filter manufacturers choose to publish their test results. See the test results for the Propur Water Filter Containers.

We use the water filter pitcher when we travel and at the office. The only drawback is that it is slow! On the other hand, it’s removing as many contaminants as an RO/Carbon Filter, so it’s all a trade-off.

The other nice feature is that the Propur filter does not strip out healthy water minerals. Each filter lasts up to 6 months, so the annual filter cost is $80.


Propur ProMax Counter Top & Under Counter Water Filters Remove Fluoride – NEW Products!


Recently, Propur released an advanced filter that removes Fluoride and over 200 other contaminants. And, this filter exceeds expectations. It makes the RO and carbon filter systems obsolete.

The Propur ProMax Counter Top Water Filter attaches to any standard faucet without a pull-out sprayer. The Propur ProMax Under Counter Water Filter system installs under the counter taking up a fraction of the space that an RO system would occupy. The filter does not waste water, does not need electricity, and does not remove healthy water minerals.

These water filters reduce/remove a broad range of over 200 contaminants including VOCs, lead, fluoride, heavy metals, pesticides, SVCs, disinfectants, inorganic non-metallics, herbicides, pharmaceuticals, PFOA, PFOS, and micro-organisms.

Tested by a certified third-party lab to meet NSF 42, NSF 53, and NSF P231 standards. See the third-party lab results on this Propur ProMax Water Filter System.

The filters last about 9 months depending on usage, so the annual filter cost is $80.

How to Choose the Best Shower Filter for Good Health

Most shower filters aren't worth it. Discover how to choose the best shower filters that are good for your health. Click to learn more or PIN to save for later.

Most shower filters are not worth it. It’s a bold statement. But, it’s true. The reason is pretty simple.

Most shower filter manufacturers use outdated filter technology. These outdated shower filters primarily remove Chlorine and a handful of other contaminants.

So, what about the other 200+ contaminants in your water? The best shower filters use advanced technology that reduces more contaminants like VOCs, lead, heavy metals, pesticides, and herbicides.

You won’t find that kind of performance with most shower filters.


Why are Most Shower Filters Ineffective?


Why is the effectiveness of most shower filters so limited?

The older filter technology is limited by water flow rate. For a shower, you need a water flow rate of 2.0-2.5 gallons per minute. If the rate is any lower, you’ll have to dance around in the shower to get clean. Most manufacturers use filter materials that allow for a fast flow with the downside of limited contaminant reduction. The older technology is only capable of removing Chlorine, rust and the rotten egg smell at that flow rate.

Sure, the shower filters worked great for people who simply wanted to remove Chlorine. But, what if your water department used Chloramines and not Chlorine to disinfect your water?

These filters are not designed to remove Chloramines or most other contaminants. And, more water departments are switching to Chloramines as a water disinfectant. An estimated 20% of water departments use Chloramines now as a water disinfectant.


Why a Shower Filter Matters


So, why bother with filtering your shower water? It matters because your shower produces significant amounts of airborne contaminants.

How does this happen? The heat and water spray from your shower creates airborne contaminants. These airborne contaminants create indoor air pollution. Studies show that inhaling these airborne chemicals is more dangerous than drinking the chemicals in unfiltered tap water.

These contaminants can increase your cancer risk, cause birth defects and adverse pregnancy outcomes.

It’s a troubling thought, isn’t it?


How to Choose the Best Shower Filters


To choose the best shower filters, look for advanced filter technology.

The best shower filters use advanced technology like the Propur Promax shower filter. It has a good flow rate (2.0 gallons/min) and removes over 200 contaminants. That’s 40-50 times more contaminants than most shower filters remove. It also helps improve odor and taste.

This filter is high-efficiency. It uses a proprietary filter media that targets specific contaminants.

The Propur Promax shower filters reduce contaminants like VOC’s, lead, fluoride, heavy metals, pesticides, SVC’s, disinfectants (Chloramines & Chlorine), inorganic non-metallics, herbicides, pharmaceuticals, PFOA, PFOS, and micro-organisms.

When choosing the best shower filters, you should also look for third-party testing. It’s easy for water filter manufacturers to make claims, so you want to see the third-party lab results from a certified lab. If the test results aren’t published, then don’t buy the filter.

The advanced filter technology has opened the door for healthier showers.

How to Choose Whole House Water Filters

Do you have questions about buying a whole house water filtration system? Get the info you need to make the right decision. Click to read the full article or PIN to save for later.

One of our Dallas readers sent us this question about how to choose Whole House Water Filters.

“I want to install a whole house water filtration system but not crazy expensive. Are there one of two companies you could recommend? There are tons listed in the area and I’ve heard there are a lot of flaky companies out there.”


Our response – Here’s How to Choose Whole House Water Filters


We know what you mean about purchasing a whole house filter and not knowing who you can trust. Many companies make claims that just aren’t backed up with facts and third-party lab results. These are the steps we recommend to choose whole house water filters.


Do Some Background Reading


If you haven’t yet, please consider reading our article on Whole House Filters – Confused about Whole House Filters? This will give you a good start. In this article, you’ll discover three critical things you should know before purchasing a filter.

Confused About Whole House Water Filters?


Know Your Water Department’s Chemical Disinfectants


You should start by understanding which chemical disinfectant your water department uses. Why? Because it will determine which type of whole house filter you need. You wouldn’t want to purchase a filter that is primarily geared to removing Chlorine if your water department uses Chloramines as a disinfectant.

Since you’re in the Dallas area, I think you probably get your water from Dallas County Park Cities Municipal Utility District and they use Chloramines and not Chlorine as a water disinfectant.

How do you find this information?

Simply google the name of your city including the term “water department” or “water quality”. You should easily be able to find your city’s water quality report. When you read the report, it will be obvious which disinfectant they are using.


We Recommend Austin Springs Whole House Filters


We recommend the Austin Springs Whole House Filter which is third-party tested and NSF certified (#42 & #53) to remove certain water contaminants. Aquasana, a well-known name in water filtration, makes the Austin Springs filters in the USA and supports them with a 3-year warranty.

Whole House Water Filter Austin Springs

Any licensed plumber can install this whole house filter. After installation, you can change the filters without tools or help from a plumber.

If you decide to go with a different system, we recommend only buying filters that are third-party tested and certified by NSF. You’ll want to look for NSF certification #42 & #53 for your whole house filter.

PLUS, you need to ask for the lab report.

Why? Because even certified filters perform at different levels. For instance, the Austin Springs Whole House Filter reduces 90% of chloramines and other filters may only remove 50% of chloramines.


Don’t Buy it without Third-Party Lab Report


We advise people to only buy water filters with a third-party lab report. Trustworthy water filter manufacturers hire a certified third-party lab to test their filters and they publish the results.

Period.


Want a Custom Whole House Filtration System?


If you want a custom system (perhaps with a reverse osmosis tank, etc.), then look for certified professionals:

  • Certified Water Specialist (CWS) 
    This designation is best suited for professionals who provide solutions to “problem water” issues and health-related contaminants.
  • Certified Installer (CI) 
    This designation is ideal for professionals who specialize in installing water quality improvement products.

Don’t settle for uncertified businesses because you only want to hire certified professionals.

Armed with the facts, you don’t have to feel overwhelmed when choosing a home water filtration system.

Is Your Refrigerator Water Filter Really Good Enough?

Is Your Refrigerator Filter Really Good Enough?

One of our readers wanted to know if refrigerator water filters were adequate or if they would be better off with an under counter water filter. It’s a question that many people struggle with.

Is your refrigerator water filter good enough to produce clean drinking water for you and your family?

Of course, there’s no simple answer because the answer depends on the following:

  • the contaminants you want to remove
  • the quality of the refrigerator water filter

Limitations of Refrigerator Water Filters


If you want to remove the most contaminants possible including Arsenic, Fluoride, Nitrate and Nitrite, Barium, Selenium, and Radium, even the best refrigerator filters aren’t able to remove these contaminants.

Why?

Because refrigerator filters use only a carbon filter and carbon filters have limitations on contaminant removal. So, if you want maximum contaminant removal, then you’ll need to opt for a carbon filter with a reverse osmosis filter or a carbon filter combined with another media. Although many carbon filters are highly effective, there’s a limit to the type of contaminants these filters can remove.

If you’re not worried about the contaminants listed above, then you might be fine with a refrigerator filter. But, you need to gather information about the filter. We recommend buying filters that are NSF certified. NSF certification means that a trusted third-party lab has verified the manufacturers’ claims.

Why are testing and certification important?

Many water filter manufacturers make claims of being the best, but not all take the next step to prove their filter’s performance. If a manufacturer really believes in their product, they get it tested and certified by NSF. And, they make those test results available on their website for your review.

If their product is not tested and performance results aren’t available, you’ve got to ask yourself why.


You Must Find & Read the Fine Print


For refrigerator water filters, the two relevant certifications are NSF 42-Aesthetic Effects and NSF 53-Health Effects. You’ll want to choose one that has both certifications. Here’s the catch, though. It’s not enough to just check for certifications, you need to read the results.

Yes, it’s a lot of fine print!

But even with NSF certification, the quality of the filters can vary widely. For instance, some filters may only be certified to remove 6 or 7 contaminants while others are certified to remove over 50. You’ll also want to pay attention to the level of contaminant reduction. Once again, there can be wide variations. Some may only reduce a contaminant by 50% and others may reduce it by 95%.


The Typical Water Filter Disclosure is Inadequate


Here’s a typical refrigerator water filter effectiveness disclosure:

  • This filter is NSF-certified to reduce lead, asbestos, chlorine taste and odor, sediment and trace pharmaceuticals.*
  • *Contaminant reduction certified by NSF.
  • Reduces lead, asbestos, chlorine taste, and odor, sediment, and pharmaceuticals
  • NSF Certified

It’s really not enough information, right?

Although, it’s good to know it reduces lead and chlorine, but it doesn’t say how much. And, you’d probably like to know if it’s going to reduce 50% of lead or 99%.

It’s great that it is NSF certified, but you don’t have the report outlining the results. Plus, there’s another issue here. If your water department uses chloramines as a water disinfectant instead of chlorine, then this filter won’t reduce the water disinfectant. And, about 20% of water departments use chloramines as a water disinfectant rather than chlorine.

What you really need is a copy of the third-party testing results. Here’s an example of a test report below from an Austin Springs’ filter.

Refrigerator Water Filters NSF Report

With this report, you’ll know exactly what kind of filtration you are getting.

To summarize, a refrigerator water filter may work for you depending on the contaminants you want to remove as well as the quality of the filter. But, you’ve got some work to do!
