How do you pick the best water filter?
When choosing a water filtration or treatment system for your home:
Determine what’s actually problematic in your water
Determine which treatment technology you’ll need
Choose a brand with certified filtration products
Consider your water usage and personal requirements
Find a certified professional if you can’t install the system yourself
Researching the best water filter can be hard. Water quality content is usually written by filtration companies or government agencies. For various reasons, this can make it difficult to get the unbiased information and advice you’re looking for.
That’s why we’ve prepared this Ultimate Guide to help you make smart decisions on which water filtration to choose. In fact, after reading this guide, you might discover you don’t even need a filter in the first place.
Determine What’s Really In Your Water
One of the first and most important parts of picking a good water filter is evaluating what your water filter will need to filter out.
Water Quality Data
The Federal Environmental Protection Agency (EPA) regulates public water system drinking water quality. The EPA’s main list of health risks in tap water includes more than 100 contaminants. Some of the most common drinking water risks include:
To determine what’s in your water, you need to do a water quality test.
114 Analytes Tested
Ideal baseline for testing tap water provided by a water utility utilizing chlorine disinfection or a private well near areas of heavy agriculture or industry. Test your drinking water for some of the most common concerns found in tap water.
Note: DIY home test strips are rubbish for water testing. Find a certified lab through a service like Tap Score or call a lab facility directly.
If you want to skip paying for a water test, then you can try to guess based upon publicly available data. This can be tricky because without a water sample that has passed through your neighborhood distribution and your home’s plumbing, the best data available will still not represent your actual tap water.

Determine What Treatment Technologies You Really Need
Tap water and well water can contain many different types of contaminants. These contaminants require different treatment technologies. No technology can remove everything (despite what companies may claim on their websites).
Water Treatment Technologies
There are more than 20 core water treatment technologies. It’s important to choose the right one to address your home’s water quality risks. Here is a list of the most common technologies for home and apartment water filtration and treatment.
Anion or Cation Exchange
- UV disinfection
Oxidation and Filtration

Choosing Your Water Filtration Brand and Product
Now that you have the information you need to purchase the right water filtration system. You need to look for a brand that sells (and maybe installs) certified products with the technology you need (reverse osmosis, carbon filtration, ion exchange, aeration, UV… etc).
Organizations like the Water Quality Association keep record of product certifications (others listed below). If you need help picking between brands and products with the right certifications, you can contact your Tap Score project manager.
Consider A System That Meets Your Personal Requirements
Choosing the right product technology and brand is not complete without thinking about where this product must go. Do you live in a small apartment or do you have a giant garage? Do you need to treat ALL your water or just the drinking water? Choosing the right installation location is really important.
For example, lead is commonly found in plumbing, so if you remove it at the entrance to your home, your water might get re-contaminated as it passes through your home’s pipes. In this case, you’d want a point-of-use solution (i.e. a counter-top or under-sink or pitcher unit) .
Find a Certified Professional If You Need Installation Help
If you purchase a product that requires substantial installation then you may need professional help. This is particularly true for point-of-entry filtration systems. These are often larger, more expensive, more complicated and require more expertise with plumbing and mechanics.
The Water Quality Association keeps a robust record of Master and Certified water filtration installation personnel across the USA. Consult the WQA Find a Member directory and be sure your product is properly installed. IAPMO maintains a similar director but it’s a bit broader than just water filtration installers.
Follow The Instructions!
No engineered product works properly unless the instructions are followed. It would be a shame to buy a water filter that doesn’t work because it isn’t installed properly or maintained. Usually this is really simple to do if you read the instructions and keep track of the months between filter changes. The leading cause of filter failure is people forgetting to change the filter on time!
