Staying hydrated is a simple and important task that water filters can make safer. Although tap water is a convenient way to get your recommended eight glasses of water per day, it may contain contaminants such as heavy metals such as lead, cadmium, mercury, and arsenic, small bits of plastic known as microplastics, or chemicals that affect taste and smell such as chlorine. These contaminants can be removed by the best water filters, but they are not a one-size-fits-all solution.

To select the best water filter for you, you must first understand what is in your water. If you have access to public drinking water, there are regulations in place that ensure it is clean and safe to drink, according to Jamie Gershel, MS, RD, registered dietitian of Jamie Gershel Nutrition. Begin by reviewing your local water utility’s annual water quality report or using a home water quality test kit.

Top 5 Water Filters On The Market Today

Remember that water filters differ not only in their filtration methods but also in their ease of installation and price. The Big Berkey Gravity Fed Water Filter, which can hold 2.25 gallons of water at a time and removes bacteria, parasites, and heavy metals, is our top pick. We like the Pur Plus Faucet Mount Water Filtration System for a more localized solution because it is simple to install directly on your faucet for filtered water on a tap.

While selecting a water filter will depend on your specific needs and whether you need a faucet filter, a water bottle filter, or a whole-house filter. We interviewed registered dietitians and compared filters based on their types, filtration processes, third-party certifications, contaminants removed, cost, and ease of use.

Here are the 5 best water filters available online.

5. Pur Classic 11 Cup Water Filter

Pur Classic 11 Cup Water Filter

Why We Like It: This NSF-certified pitcher removes contaminants, is dishwasher safe, and can fit in your fridge.

It’s Worth Noting: The filter must be changed every two months, which is more frequently than any other product on this list.

A pitcher may be a good option if you want to filter your water easily without having to install a filtration system. We like that this Pur filter is NSF certified, so we know it’s a reliable product that removes the contaminants it claims to.

Above all, this filter is convenient and simple to use. It has a spill-resistant lid and allows you to pour while the water is still filtering. The filter is also dishwasher safe, which is important because bacteria can grow easily inside water filters.

The Pur filter can fit inside your fridge door and holds 11 cups. Changing the filter is also simple, with an electronic filter replacement indicator that illuminates when the filter needs to be replaced. The filter must be replaced every 40 gallons, which takes about two months. Pitcher filters require more frequent replacement than larger filters, such as those that go under the sink, and this can add up over time.

Product Details:

  • Filter Replacement Frequency: After 40 gallons or around every 2 months
  • Annual Filter Replacement Cost: $143
  • Capacity: 11 cups
  • Dishwasher Safe: Yes
  • Additional Maintenance Required: Should be washed in the dishwasher

4. Express Water 3 Stage Whole House Water Filtration System

Express Water 3 Stage Whole House Water Filtration System

Why We Like It: This filter removes major contaminants and sediment from the water, providing clean water and protecting your appliances.

It’s Worth Noting: Whole-house filtration systems are costly, and installation may require the services of a professional.

Whole house water filters can be useful if you have hard water or want to remove large amounts of sediment or dirt from your water. If you only want to filter water for drinking, you might be able to get by with an under-sink filter or a faucet attachment. If you use well water, have a strong odor in your water, or want cleaner and better-smelling water for your entire house, a whole house filtration system like this one from Express Water is your best bet.

According to Elizabeth Barnes, MS, RDN, LDN, a non-diet dietitian of Weight Neutral Wellness in North Carolina, whole house systems not only provide clean water, but they can also extend the life of pipes and appliances like your dishwasher and laundry machine. Heavy metals, chlorine, rust, pesticides, dirt, sand, lead, and other impurities are removed by this Express Water whole-house filter.

Some whole-house filtration systems can affect water pressure. This filter, on the other hand, is designed to provide a high flow rate of up to 0.25 gallons of water per second. Although whole-house filtration is more expensive, the filter only needs to be replaced every 6 to 12 months. If you don’t require a whole-house filtration system, we believe one of the other options on our list is a better fit.

Product Details:

    • Filter Replacement Frequency: 6 to 12 months
    • Annual Filter Replacement Cost: $100-$200
    • Capacity: 100,000 Gallons
    • Dishwasher Safe: N/A
    • Additional Maintenance Required: We May need a plumber for installation

3. Pur Plus Faucet Mount Water Filtration System

Pur Plus Faucet Mount Water Filtration System

Why We Like It: This filter easily attaches to your faucet and will notify you when it is time to change the filter, eliminating the need for your calendar reminder.

It’s Worth Noting: While this filter is compatible with many sinks, it is not compatible with a popular pull-down or handheld faucets.

A faucet mount is a simple way to filter water directly from the faucet. The Pur Plus Faucet Mount filters water using ion exchange and activated carbon. Adsorption, a process in which pollutants are attracted to carbon, helps activated carbon remove chemicals. Ion exchange is a technique that employs a resin to replace harmful ions, or impurities, with less harmful ones. This model is certified to reduce impurities such as lead and mercury, as well as chemicals such as chlorine, which can impart an unpleasant taste to your water.

Another advantage of this low-cost faucet mount is its ease of installation and use. You can install the filter on your own, without the use of tools or a plumber. The filter has an on/off switch so you can choose when to turn it on—for example, if you only want to use it for drinking. It also has a changing light that alerts you when your filter needs to be replaced, which is approximately every three months.

Product Details:

    • Filter Replacement Frequency: Up to 3 months
    • Annual Filter Replacement Cost: $50
    • Capacity: 100 Gallons
    • Dishwasher Safe: N/A
    • Additional Maintenance Required: None

2. Frizzlife Under Sink Water Filter System

Frizzlife Under Sink Water Filter System

Why We Like It: It won’t take up valuable counter space or be an eyesore on your sink faucet as an under-sink filter.

It’s Worth Noting: Every three to six months, the inner filter should be replaced.

Under-sink water filters make it simple to drink filtered water straight from the tap for drinking, cooking, and cleaning. One of the advantages of this filter is that it is simple to use and install—you can do it without the assistance of a plumber.

NSF/ANSI 53 & 42, an organization that develops health standards for products, has third-party certified the Frizzlife Under Sink Water Filter System. These certifications ensure that a product removes a specific set of contaminants from drinking water, both in terms of chemicals that can alter taste or odor and contaminants that can cause health problems.

Frizzlife claims to remove 99.99% of all contaminants, including chlorine, lead, and heavy metals while leaving essential minerals in place. Leaving these minerals in your water can help ensure that it still tastes good.

What distinguishes this under-sink filter from others, and a major reason we recommend it: the Frizzlife filter is also simple to replace. Because the filter has an integrated shut-off valve, you do not need to turn off the water supply when replacing the filter cartridge. Instead of replacing the entire plastic housing, you only need to replace the inside cartridge, making this a more environmentally friendly option.

Product Details:

  • Filter Replacement Frequency: 3 to 6 months
  • Annual Filter Replacement Cost: $40-80
  • Capacity: 2 Gallons Per Minute @ 60 psi – fills 330 ml cup in 3 seconds
  • Dishwasher Safe: N/A
  • Additional Maintenance Required: Requires installation

1. Big Berkey Gravity Fed Water Filter

Big Berkey Gravity Fed Water Filter

Why We Like It: Big Berkey has a large capacity and only requires filter replacement every three years.

It’s Worth Noting: This filter is more expensive than others and requires more counter space.

If you want an easy-to-use, large, and long-lasting water filter that can provide clean water for a large group, the Big Berkey Gravity Fed Water filter is a great option—and our top pick. This filter is simple to use, relying on gravity rather than electricity or pumps. And because the filter is portable, you can place it wherever you want.

The Big Berkey Filter removes over 200 contaminants using carbon and ion exchange, including bacteria, pesticides, and heavy metals. It is also built to last because it is made of stainless steel rather than plastic and has a long-lasting filter. The filter only needs to be replaced after 3,000 gallons, or about three years (and because this model includes two filters, you won’t need to replace anything for up to six years). It also has a large capacity, holding 2.25 gallons at a time, making it an excellent choice if you have a family or live with others.

While this filter is an investment, we believe it will be worthwhile in the long run. Unlike most filters, which require frequent replacement, the Big Berkey is a low-maintenance filter you can rely on. Click here to buy this water filter.
