Best Faucet Mount: PUR Faucet-Mount Water Filtration System

Buyer’s Guide

Before buying a water filter, there are a few factors you should consider. In addition to the type of water filtration system, you’ll also want to consider what impurities the system filters out and how long its cartridge lasts.

Filter Type

There are five types of products that remove contaminants from your water.

  • Pitcher: This is the most common type of water filtration system. The top third of the pitcher is where the water sits when you first fill it with water. The water trickles down to the bottom portion of the pitcher as it passes through the cylindrical filter in the middle.
  • Countertop: This type of water filter is similar to a pitcher except it can hold more filtered water. This decreases how often you have to refill it. It also sits on the counter instead of in the refrigerator.
  • Faucet mount: This type of filter is mounted to your kitchen sink. It filters the water as you pour it into your glass, eliminating the need to store filtered water in your fridge or on your counter.
  • Whole-house: If you live in an area with poor water quality, you may want to consider a whole-house filtration system. These are more expensive and more difficult to install, but they ensure that any water you use in your home is free of contaminants.
  • Water bottle: If you’re planning a trip and want to ensure that the water you encounter is safe to drink, consider bringing along a water bottle with a built-in filter. The filter sits in the center of the bottle and filters out contaminants as you pour in the water.

Filtered Contaminants

Not every filtration system filters out the same impurities. If the water in your area is mostly clean and you just want to improve the taste of your water, any filtration system will work. However, if there are specific contaminants you want filtered out, you may want to invest in a water filter that has multiple levels of filtration.


Water filters require continuous upkeep—you can’t just install a filter and use the system for an indefinite amount of time. Most filtration systems have an indicator that lets you know when you need to replace their filter.

Frequently Asked Questions

Can I buy a pack of replacement filters?

Yes. When you purchase a water filtration system, you’ll likely be given one or two filters to start with. However, you’ll have to buy the replacements once those filters are used. It’s more cost-effective to buy a pack of several filters at once than a single one each time your filter needs to be replaced.

What do NSF and ANSI certifications on a water filter mean?

National Sanitation Foundation (NSF) International is a nonprofit organization that promotes sanitary living conditions across the world. The American National Standards Institute (ANSI) has a similar mission, except the organization exclusively works in the United States. Both of these organizations offer similar certifications on water filtration systems to let customers know how well the products filter out contaminants.

Two common standards you might see from these organizations are:

  • Standard 42: These water filters filter out non-health-related contaminants, such as chlorine, taste, odor, and particulates.
  • Standard 53: These water filters filter out health-related contaminants, including cryptosporidium, giardia, lead, and volatile organic chemicals.

What are some of the most trusted water filter brands?

PUR and Brita are two of the most trusted water filter brands that create pitcher, countertop, and faucet-mount systems. If you’re looking for a water bottle filter, LifeStraw is a well-known option.
