Water is essential to life. Hydration is a cornerstone of good physical health. But finding clean, contaminant-free water is challenging for some people who rely on municipal water systems or groundwater at home or work. 

That’s why there are filtration systems that attach directly to the faucet or come in a self-contained pitcher. Either style provides healthy, drinkable water whenever you want it. 

In this article: Aqua Crest NSF Certified Water Filter, Brita Tap Water System and Aquagear Water Filter Pitcher.

Do I need to filter my drinking water?

According to the Centers for Disease Control and Prevention, the drinking water system in the United States is among the safest in the world. But since all drinking water contains minerals and trace levels of contaminants, additional filtering may be needed.

While municipal systems are regulated by the Environmental Protection Agency, homeowners with private well systems are responsible for their own water quality. Even though water in the United States is generally safe to consume, additional filtering is about peace of mind for some people.

Faucet water filter system pros and cons

With a faucet water filter, you have an unlimited supply of water filtered instantly. You don’t have to worry about running out of water for cooking or drinking. 

Faucet systems are also easy to install and don’t require a lot of tools or expertise, as long as you have a standard faucet. If you have a designer or custom-made faucet, the filter may not work out of the box. 

Many faucet water filters have a button or switch that transitions between filtered and unfiltered water for convenience and conservation. This extends the life of each filter cartridge. 

Water filter pitcher pros and cons

Water filter pitchers provide great-tasting, odorless drinking water. They remove a wide range of contaminants, including lead, chlorine, microplastics, pesticides and microorganisms. They can be stored in a refrigerator for cold water, and they are portable if you need to take water with you.

They are limited by size, though. When the pitcher is empty, you must start the process over. This could be challenging for large families or when entertaining guests.

Pitchers are easy to clean, but the design of the pitcher is important since some corners can be difficult to reach. 

Replacement water filters are inevitable

No matter which style you choose, you’ll need regular replacement filters. Normal use requires a replacement filter every two to three months. Looking at replacement filter prices and calculating your annual cost will help determine which model is best for your budget.

Consider having your water tested

Most filters today use active carbon, but some filters include ion-exchange technology that removes even more impurities. The best filters are ceramic filters, but they are less common.  

If you’re concerned about what contaminant levels are in your water, you can contact your local water utility for a free report or purchase a do-it-yourself testing kit. 

Certification is peace of mind

You may want to shop for filters that have been certified by the National Sanitation Foundation or the American National Standards Institute. These certifications ensure that the filters have been third-party tested and actually remove the impurities they claim to.
