Best Water Purifier Buying Guide for 2022

Best Water Purifier Buying Guide for 2022

For many, one of the best water filters is an absolute essential in the home, unlocking access to purified water whenever you want it. An inexpensive yet hugely impactful investment, one of these filters will make your drinking experience more enjoyable, and allow you to reduce your plastic use at the same time.

Water filters not only help improve the flavor of your water but also protect you from impurities such as rust particles and harmful contaminants such as bacteria and lead.Sure, bottled water is easily available as a quick and (initially) cheap solution, but water filters are more sustainable—and can save you money in the long run.

There are, however, countless types of water filters available on the market, each differing in what they remove from your water. These include under-sink filters, faucet attachments, whole-house filtration systems, pitcher filters, and more. While there isn’t a one-size-fits-all filter solution, we help narrow down the list of the best water filters based on your needs. Each item included in this roundup has either been certified by the NSF, a health and safety standards testing company, or tested and certified by an independent third party to meet NSF standards.

It’s important to note that the best water filters are versatile when it comes to design. If you want purified water when you’re in the office, or out on a run, you don’t need to strictly decant from your water filter jug. Instead, you can browse bottles with water filters built-in, or adapt your faucet to have purified water flowing all of the time.

Best Water Purifier Buying Guide for 2022:Our choice

1.Aquasana 2-Stage Under Sink Water Filter System

View on Amazon

Under-counter filters have the benefit of purifying all of the water that comes out of the faucet. Choices such as these happen to be expensive and complicated, whereas the Aquasana 2-Stage Under Sink Water Filter is anything but; it is an exceptional selection.

Here, this best buy strikes a balance between price and effectiveness, particularly as you’ll notice it comes equipped with a chrome faucet.

Nevertheless, while the features and functions are fantastic, the set-up is another story, as it is designed to be a DIY-yourself; prepare to invest a decent amount of time into its set-up, as it’s known for being difficult. A handful of users have noted that the plastic joints (included in the set-up) can leak a little: so be careful as you install them.

When properly installed: the two-stage filtration system will remove up to 97% of chlorine, as well as lead, asbestos, herbicides, and pesticides; dealing with upwards of 60 common water contaminants with every use, and at a flow rate of only 0.5 gallons per minute. (Which is good since filtrations cost a minimum of 10 cents per gallon!)

2.Brita Extra Large 18 Cup Filtered Water Dispenser

View on Amazon

If you like the idea of having a lot of filtered water readily available but don’t want the DIY hassle of an under-counter or countertop filter, the Brita Ultra Max Dispenser could be for you.

With an 18-cup capacity, this slimline dispenser has enough water for the entire family. Designed to sit on a counter without taking up too much space, but you can slide it into a refrigerator, too.

As this is a large item and heavy when filled with water, there’s a spigot on the front for filling up cups or bottles, and it has a decent flow rate.

This model ships with Brita’s long-life filters, which require changing after 120 gallons (there’s an indicator on the lid that tells you when). You can use the standard 40-gallon filters, too.

Some owners have found it hard to get the black plastic lid off to replace the filter.

Refilling is straightforward enough, with water going in at the top and filtering through to the bottom. This product is a little cumbersome and heavy to move.

Brita says its filter can remove 99% of the chlorine and lead, plus cadmium, mercury, benzene, and more. Owners generally report an improvement in water taste.

Overall, if you don’t want to plumb in a water filter but want a lot of capacity, this is the product for you.

How We Selected

To determine the best water filters, we spoke with several registered dietitians about the differences between the types of water filters and the types of contaminants they filter. We prioritized filters that have been third-party certified, but didn’t use that criteria as automatic grounds for dismissal from our list.

In reviewing the various water filters on the market, we took into consideration filtration methods, contaminants removed, ease of installation, and lifetime costs and maintenance. We offered a range of filter types so you can find one that best meets your needs—and your budget.

What to Know About Water Filters

When shopping for water filters, it is important to first know what contaminants are in your water. Based on this information, you will be better equipped to decide which treatment solution addresses your concerns. It is important to note that not all filters or filtration methods remove all contaminants.

Types of water filtration methods:

  • Activated carbon filters: These filters use activated carbon to soak up impurities that produce unpleasant tastes or odors. This can include organic matter, volatile organic compounds, chlorine, and others per the Environmental Protection Agency (EPA).
  • Ion exchange filters: Water is passed through synthetic resin. Harmless charged ions on the surface of the resin are exchanged with harmful charged contaminants in the water. This can be useful for removing arsenic, chromium, cyanide, and other impurities.
  • Reverse osmosis filters: This process forces water at high pressure through semipermeable filters, removing a larger range of contaminants such as heavy metals, bacteria, and viruses.
  • Mechanical filters: Water is passed through a mesh filter that traps particles. These types of filters remove larger materials such as sand, silt, and organic matter.
  • UV filters: Ultraviolet light can be used to remove microbial contamination in water, reducing bacteria, protozoa, and viruses present. UV light is not, however a filter, but rather a method of disinfection. It does not remove contaminants such as heavy metals, chlorine, or chemicals. UV filtration will not improve the taste or smell of your water.
  • Commonly filtered contaminants: Different filters are able to filter varying contaminants. The common contaminants include those that can impact taste and smell, such as chlorine. Chlorine is often added to water as a disinfectant to kill microbial organisms, but it can result in an unpleasant taste.

Other contaminants water filters may remove include microplastic particles, fluoride, larger particles like sediment or sand, or harmful toxic heavy metals such as lead, mercury, cadmium, and arsenic.

The contaminants a filter is able to remove will vary, so be sure to check for a list of contaminants your filter removes or reduces.

Installation

Water filter installation will vary based on the type of filter. Certain filters such as pitchers, counter top, water bottle, and certain faucet attachments and under sink filters can be installed on your own. For whole house filters, you will likely need to hire a professional.

Lifetime Costs & Maintenance

Water filters need to be replaced every so often to ensure they continue to function properly. Smaller filters such as pitchers, faucet attachments, or countertop filters often have to be replaced every 2 to 3 months. While this is usually an easy process, it can add to overall costs over time. Larger filtration systems, such as whole house filters, often require less frequent replacing.

What is the healthiest way to filter water?

The healthiest way to filter water will depend on the contaminants in your water, which is why we recommend testing your water first, if possible.

Filters that use activated carbon remove impurities like chlorine, which can improve the taste and smell of your water. Other processes such as reverse osmosis are suitable for more in-depth filtering because this removes most chemical contaminants such as bacteria and heavy metals like lead, arsenic, and cadmium.

Should the water purifier always be on?

Water purification systems are made to operate almost continuously, and switching them on or off unnecessarily can damage the parts.

What should we check before buying a water purifier?

Water quality, TDS, and water pressure are the main factors that you should check before buying a water purifier.
