Our Water Filter Findings

Brita Standard Replacement Water Filter, 3-Count

Best Overall

What We Liked: With this pack, you’ll get three filters, each of which fits all Brita pitchers and dispensers except the Brita Stream line. Brita filters reduce chlorine and get rid of the taste and smell of any copper, mercury, zinc and cadmium in your water. Unlike earlier versions of Brita filters, these filters are easy to install and require no presoaking before use.

Frizzlife Under Sink Water Filter System

What We Liked: This filtration system fits under your sink for great-tasting water at the turn of a faucet. The filters are rated to remove up to 99.9% of the taste and smell of chlorine and lead, and they filter out particles down to 1/2 microns. The filter comes with direct-connect hoses that fit standard 3/8-inch feed water valves found under kitchen sinks.

ZeroWater Replacement Water Filter, 2-Pack

What We Liked: This two-pack will work with all ZeroWater pitchers and water dispensers, no matter the size. These filters use a five-stage process that reduces lead and other heavy metals in your water, and filters 99.6% of total dissolved solids. You can buy them in other multi-set configurations or with a pitcher if you don’t yet have one.

PUR PPF951K3 MineralClear Replacement Pitcher Water Filter, 3-Pack

What We Liked: This three-pack will last you about six months, ensuring you always have one on hand when it’s time for a change. These filters are compatible with all PUR water pitchers, so you won’t have to worry about matching serial numbers. These filters will reduce some pesticides, heavy metals and lead in your tap water.

CuZn UC-200 Under Counter Water Filter

What We Liked: If you’re looking for an under-counter filtration system, this one does the job while preventing the growth of bacteria and mold. It’s easy to install if you have standard plumbing, but even if you don’t, you can call for a non-standard install kit that will make it easy. It uses a five-stage filtration system that gets rid of contaminates without eliminating the healthy minerals in your water.

Our Water Filter Buying Guide

Bottled water can get expensive, and all those plastic bottles are bad for the environment. You can save serious money and ease your conscience by investing in a water filtration system for your home. Even if you don’t drink all your water at home, there are insulated tumblers and thermoses that you can fill with water and take with you on the go.

Water filtration is not a complicated, involved process. In fact, you can spend a small amount of money and have water filtration right away. One of the easiest ways to do this is by using a water pitcher that holds a filter. You will have to refill it periodically, but pitchers are a great option if you live alone or your household doesn’t consume much water each day.

Another option is an under-sink water filter. You simply hook it up and enjoy tasty water from the tap. This is the route to take if you just want filtered water from one sink in your house. Or, if you’re in the market for a new refrigerator, one that has a filtered water dispenser built into the door may provide the same benefits.

Some households choose to invest in whole-house filtration systems. This can be costly and involved, but it could also increase the value of your house. The main reason to do this, though, is that it gives you the convenience of having filtered water no matter which tap you choose. You’ll also get filtered water in the bath or shower, which can be nice.

No matter what type of filtration system you choose, you’ll need to occasionally change the filter. A whole-house system won’t need it as often as a smaller system, so that’s another convenience. Look into how often the filters have to be changed, as well as how expensive and easy to buy they are, before you choose a filtration option.

DWYM Fun Fact

If you’ve been buying bottled water with the assumption that it’s straight from a natural spring, you may have been misled. About half of the bottled water sold in the U.S. comes from actual spring water, which is defined as water flowing naturally from an underground source.

The other half comes from the municipal water supply, just as your tap water does. The water is filtered and/or treated — similar to the process you’d use to filter your own water at home — then put in a bottle, labeled and shipped to the store where you bought it.

If you want to make sure you’re getting spring water with your next bottled water purchase, take a look at the fine print on the label. You can find the source there, including information on the location of the spring or water supply.

The Water Filter Tips and Advice

  • When you turn on your tap, you’re getting water from the municipal water supply in your town. While local governments do what they can to keep things safe, occasionally violations are cited, which means contaminants may be present without you knowing it.
  • The water coming through your pipes isn’t the only concern, as the pipes themselves can contain contaminants.
  • There are multiple types of filters, but the most popular is carbon. Carbon is a low-cost but effective way to filter particles.
  • Most filters are sold in sets of two or more. This can help you save money, and it also gives you one or more extras to keep on hand so you aren’t always rushing to buy a new one when it’s time to change your filter.
  • Look at the specific types of particles that are caught by your filter. Chlorine, lead, copper, mercury, zinc and cadmium are just some of the contaminants you can battle with a filter.
  • You’ll have to double-check that the filter you’re buying works with the filtration system you have in place. Some are universal, but not all of them are.
  • Some filters require that you soak them first for a period of time. Others let you skip that step, which makes changing out your filters much quicker and more convenient.
  • Check the instructions on how to change your filter. With some, you’ll need to run water through it a few times before you can drink it. The early rounds of water can be used for things like watering plants if you don’t want to toss it out.
  • Water filtration systems can build up bacteria and mold over time, as is the case with any moisture-rich environment. Some filters are designed to resist this buildup to keep you and your family safer.
