Water is essential for life… but what if the stuff coming out of your tap contains more than just H2O? Drinking water can be contaminated with foreign substances that impede your health, but by investing in one of the best water filters on the market, you can ensure you're drinking clean, purified water.

Indeed, there are plenty of ways you can filter your drinking water, and make sure you're not drinking anything you don't intend to. But does everyone need a home water filtration system? And, if so, which kind is best?

Environmental Hazards: Why Water Filtration is So Important

First, let's consider why it's important to get the best water filter possible.

For as much as we'd all prefer to believe that our tap water is crystal-clear and perfectly clean, that's simply not the reality. Remember that your water has to travel through miles of pipe just to make it to your home. Along the way, it picks up contaminants or debris from the pipe itself.

And this is to say nothing of different treatments used on residential drinking water, such as chlorine… some of which can be helpful, but many of which are not.

It may shock you to know that the average home's drinking water contains more than 300 contaminants. And if you'd rather whittle that number down to something close to zero, your best bet is with a water filtration system.

Different Types of Water Filter

So which type of water filter is recommended?

There are a number of options, and the most convenient tend to be fridge units, faucet units, and pitchers. The best water filter for you will depend on your preference.

  • A fridge filter will come built into your kitchen appliance and will help filter out any water that's dispensed from the fridge or used to make ice. If you happen to have a fridge with a built-in filter, that's great! However, by their very definition, these filters will leave other home water sources (including bathroom taps) unfiltered.
  • Faucet units help you to filter water from these other areas of your home, though again, you may need to invest in multiple units to ensure clean drinking water throughout your house.
  • Another option is to invest in a pitcher that filters water for you, making sure you always have some clean, pure drinking water handy.

Reusable Water Vessels: An Eco-Friendly Option

Of course, one way in which you can avoid drinking contaminated water is to purchase bottles of water that have already been purified. The problem here is single-use plastic.

If you do prefer to purchase water rather than use your tap, it's best to buy in large quantities. You can get a large reusable jug and fill it up at a water refill station, such as at a grocery store. Then, you can use a cup or eco-friendly water bottle to carry around throughout the day.

By having a way to purify your own water before adding it to a reusable container, you can consume healthy drinking water and exercise greater environmental stewardship.

Choosing the Right Water Filter

As you look for the best home water filters, certification is a foremost concern. Specifically, be on the lookout for water filters that rise to the level of National Sanitation Foundation (NSF) certification. NSF has rigorous, nationalized standards for clean and contaminant-free municipal drinking water, and the best water filters receive certification after undergoing a testing process.

There are several third-party and independent labs that test water filters and make sure they're up to NSF standards. Some examples include the CSA Group, Underwriters Laboratories (UL), and the Water Quality Association (WQA). If you see any of these certifications on a water filter, that's a good sign that the product has been thoroughly vetted and found to be effective.

Do You Need a Water Filter?

Most homeowners can benefit from a water filter; this is true whether you're drinking treated city water or water from a well, which can come with its own ground contaminants.

Some of the most common warning signs that you need a home water filter include:

  • Your water tastes bad or stale (usually a sign of contaminants).
  • Your home predates 1986 (in which case, there could be lead pipes bringing your drinking water).
  • You get your water from a well.
  • You wash your clothes and they come out looking dingy or dirty.
  • You have a constant build-up of scum in your sink or shower.

If you notice any of these issues, it probably means you have bad water… and, that it may be time to improve your water quality with a new filter.

The Best Home Water Filters

As for the best water filters on the market, we've tested several and are happy to recommend the following.

Each product featured here has been independently selected by the writer. If you make a purchase using the links included, we may earn commission.

PUR Advanced Water Filter

For a faucet-mounted filter, try PUR, one of the longest-running and most popular brands. This is an inexpensive way to skim out more than 70 of the most common water contaminants, leading to notably improved water taste and clarity.


Brita On Tap Water Filter

An alternative to PUR is Brita. Brita's on-tap filter promises improved water purity and major savings, as you won't have to spend nearly as much buying your water by the bottle. It can remove more than 99 percent of lead, chlorine, and other common contaminants.


Brita Pitcher

If you prefer your water filtration in a pitcher form, consider this option from Brita. It holds five cups of water, enough to fill two 24-ounce reusable water bottles.


Waterdrop Under Sink Filtration System

As for under-sink filters, we recommend this one from Waterdrop, a high-capacity filter that uses a four-stage process to ensure your drinking water is as clean as can be.


Culligan Whole House Water Filter

Whole-house filters are a little tougher to install, and require that the filter cartridge be changed regularly. In the long run, however, they can be one of the more convenient options, guaranteeing clean water from all of your taps. We like the Culligan model best of all, and it's priced very reasonably.


Get Clean, Fresh Drinking Water

Everyone wants clean, fresh, healthy water… and with the best water filters, you can get it. Start with these recommendations as you look for ways to ensure that it's only good stuff coming out of your home tap.
