Water filters can make the simple and important task of staying hydrated safer. Water from the tap may be a convenient way to get your recommended eight glasses a day and reap the many benefits, but it can contain contaminants such as heavy metals like lead, cadmium, mercury, and arsenic, small bits of plastic known as microplastics, or chemicals that impact taste and smell such as chlorine. The best water filters can remove these contaminants but aren't a one-size-fits-all solution. Water filters vary in their filtration methods, ease of installation, and cost, so choosing a water filter will depend on your specific needs and which type (e.g., a faucet filter, a water bottle filter, or a whole-house filter) will work best for you.

To help you find the best water filter for your needs, we spoke with registered dietitians and tested 24 pitcher-style and countertop filters from the top brands on the market. Over a 2-week period, we evaluated the differences in taste, odor, appearance of our filtered water, the filters' efficiency, ease of use, and overall value. We also had a dietitian on our Medical Expert Board review this article for medical and scientific accuracy. These are the best water filters that we found provided the best quality and taste during our tests.

With a 10-cup capacity, the Brita Water Filter Stream Rapids Water Pitcher includes an activated carbon stream filter, electronic indicator, and Filter-As-You-Pour™ technology within the housing. The instant filtration, compact sizing for sinks and fridges, and easy setup stood out as favorites, making this filter the best overall.

We loved the easy setup and quick use after a brief clean. Following the instructions for the first use, we filled the pitcher once, poured, and refilled it. The water filtered instantly with no wait time. The pitcher's size fit conveniently under the sink and was easy to handle. The stream poured smoothly, making it easy to fill a glass without spillage.

The filtering process was impressively simple and efficient, with instant filtering being a significant advantage, allowing immediate glass pouring. In a blindfold test, the filtered water stood out, offering a clean and crisp taste compared to the chlorine taste in the control water. The filtered water was clearer, enhancing the drinking experience. At a reasonable price of $35, this product exceeded our expectations for quick filtration. We'd even pay more for its user-friendly design and excellent performance.

Some users might find the flow rate of water from the pitcher dispenser to be slower compared to other filtration systems.

The Pur pitcher impresses with its high capacity and quick filtration, making it a reliable choice for ample filtered water. Sporting an 11-cup capacity, filter change indicator, locking, and easy-fill lid, plus a dishwasher-safe design, it's a convenient filtration solution.

While inserting the filter, clear directional arrows were helpful, but a more prominent lock icon could enhance usability. The filtration speed of approximately 3 minutes, living up to the claimed 2 times faster, was a pleasant surprise. The lightweight pitcher, even when half-filled, was easy to handle with a slim, ergonomic handle design.

Though the taste difference was subtle at first, a lighter taste emerged after a few sips, making us eager for refills. The filter worked efficiently, leaving the filtered water clear and free of visible residues. At $32 for the pitcher and $19.00 for a 3-pack of replacement filters, it's a reasonably priced choice for larger water needs.

There have been occasional complaints about the pitcher's construction, with leaks or difficulty fitting the filter properly.

The PUR PLUS dispenser impresses with its substantial 30-cup capacity and convenient features, including a filter change light and simultaneous dispensing while filtering. The LockFit™ design ensures a secure filter fit, and its dishwasher-safe, BPA-free construction enhances its appeal.

Setting up the dispenser was a breeze with clear instructions. After soaking the filter for 15 minutes, we noticed some black particles in the pitcher during washing. Cleaning the sizable pitcher was manageable, though reaching certain corners proved slightly tricky. The end handles facilitated easy carrying, and activating the filter change indicator was straightforward. While there wasn't a max fill line, it was easy to gauge when to stop filling. The filtration process for about 3/4 full took 30 minutes for the top portion and reached half capacity for the bottom tank.

In a blind taste test, the filtered water stood out with a neutral, crisp, and clean taste compared to the control. The clarity difference was evident too, with the control water showing small particles while the filtered water remained impeccably clear. Despite a 30-minute filtration time for a not-quite-full pitcher, given its features and capacity, we found the PUR PLUS 30 Cup Dispenser to be a great value, making it a worthy investment despite minor drawbacks.

The dispensing process can be slow, requiring patience when filling larger containers.

The Brita Tahoe stands as a user-friendly choice, offering a 10-cup capacity, SmartLight filter indicator, and the extended filtration efficacy of the Brita Elite™ Filter for up to six months, surpassing the standard two-month lifespan.

The pitcher's design impressed us, fitting well in the sink and featuring a thoughtfully designed handle for easy one-handed lifting. Pouring from a full pitcher was effortless without any spills, showcasing the pitcher's practical design and manageable weight.

In a blind taste test, the filtered water stood out, feeling crisp and refreshing, prompting a desire to drink more. The control water had a thicker mouthfeel and a chlorine aftertaste, reinforcing our preference for the filtered water. Both waters maintained clarity with no visible residue. Regarding filtration speed, the initial run-through took 2 minutes and 45 seconds, reducing to 2 minutes and 7 seconds in subsequent runs, requiring multiple fillings to complete the pitcher. Despite this minor inconvenience, its great value, easy fill and pour features, and modern filter notification technology make the Brita Tahoe a worthwhile choice, though the need for multiple fillings slightly impacts its overall score.

The lid design can lead to spillage or slow pouring, potentially affecting ease of use.

The Hydros 40 oz Water Filter Slim Pitcher offers remarkable efficiency, filtering up to 5 times faster while maintaining water quality. Its standout feature is the lack of waiting time for filtration, providing instant gratification. The slim design fits perfectly in the fridge, enhancing convenience. Made of lightweight, dishwasher-safe glass, it has an 18-cup capacity.

Setting up the filter was a breeze, requiring just a 15-second rinse. The filtration process matched the faucet's flow rate seamlessly, filling the pitcher without any hitches. Its slender design makes it easy to hold with one hand, despite being glass and lightweight, potentially limiting its suitability for younger users. Pouring from the pitcher was convenient, even at full capacity.

The unfiltered water had a lingering metallic taste, similar to metal tooth bracket sensations during brace-wearing days. However, the filter effectively diminished this harsh taste. Despite lacking a replacement indicator, the swift filtration and glass build make this filter worth the price. For those seeking a capacious pitcher, its larger size and increased water capacity are notable advantages. The membrane microfilter lasts for 264 gallons (about 1 year), while the coconut shell carbon and ion exchange filter last for 40 gallons (about 2 months), prompting users to change it every two months or when a noticeable taste difference arises.

Due to the smaller size, users might find themselves refilling the pitcher frequently, which could be inconvenient for those with higher water consumption.

The Epic Nano stood out to us for its great tastes, thanks inpart to the inclusion of a sub-micron filter which removes chlorine, virus, lead, microplastics, giardia, and more. When we tested the filtered water, it was impressive. It had a remarkably clean and fresh flavor, without any metallic or chemical undertones, and we didn't notice any settled particles or noticeable bubbling. 

Filling the entire pitcher at once was effortless; it's so user-friendly that even a child could manage the process from start to finish. However, the filtration process took almost 12 minutes in total. Everything was manual, leaving no option to speed up the process. Fortunately, it easily fit under the faucet and filled up rapidly.  Both the filter and pitcher are lightweight, even when full, and can be operated with just one hand. Pouring into glasses was seamless, with no spillage or leaking.

The Nano Pitcher also comes with an integrated LED timer in the lid that counts down from 90 days. This handy feature serves as a reminder to change the filter when needed. Considering that fridge filters usually cost around $60 each and last for about 3-6 months, we think the $70 price tag for this product seems quite reasonable.

While portable, the Epic Nano Filter might be bulkier compared to other compact filtration options available for travel or emergencies.

The PureVis™ pitcher melds water purification with advanced digital technology, driven by mercury-free, ozone-free carbon-derived plant-based filters and a rechargeable lithium polymer battery, complemented by a smart sensor monitoring the filtered water's flow rate for timely filter replacement.

Tasting the filtered water revealed a subtle sweetness, contrasting distinctly with the chlorine taste found in the control water. Side-by-side comparison exposed the filtered water leaving a "dry wine" sensation akin to moisture extraction seen in hard water.

Setting up involved a ten-minute filter soak, the most time-consuming part. Disassembly, albeit slightly challenging, and charging the battery were additional steps. Surprisingly, the filtration process took under 4 minutes. The pitcher's design was user-friendly, with a pressure-sensitive flap securing the lid during filling and lightweight plastic ensuring effortless pouring and filling. Its higher price, attributed to electronic features, places it in a premium category. An accompanying app provides detailed water information, catering to tech-savvy consumers.

While the filter's lifespan is longer, replacing it might be more involved compared to traditional filter cartridges, potentially requiring more time and effort.

This Amazon pitcher is certified to reduce chlorine taste and odor, copper, mercury, and benzene, and holds a WQA certification, bearing the gold seal against NSF/ANSI Standards 42 and 53. Thanks to its multi-stage filtration technology, it consistently delivers fresh, great-tasting water. Each filter lasts for 40 gallons or approximately two months for the average household. The BPA-free pitcher features a large 10-cup capacity, Secure Lid Technology to ensure no gaps or leaks, one replacement water filter, and the electronic MEMO function simplifies filter change reminders. In the blind taste test, the filtered water had a delicate sensation of lightness on our tongues. The filtered water displayed remarkable clarity, free from cloudiness, particles, or coloration. Our unboxing and setup journey took us about 18 minutes from its packaging to filled with filtered water. We had to run water through the filter twice and discard it to ready the filter for action. When filling the reservoir, it took approximately 2 to 2.5 minutes for the reservoir to empty. A full pitcher would require 5 to 9 minutes, depending on how much you fill it.  The pitcher's space-efficient design fits seamlessly on refrigerator shelves.

With its multi-stage filtration technology, this pitcher holds its own, although the handle isn't as spacious as others. The electronic filter change indicator is a standout feature, but we were disappointed that the flapper over the spout broke due to difficulties removing the reservoir from the pitcher. However, priced at $26 for the pitcher and the filters less than $5 each, we think this option seems to be a reasonably good deal.

The pitcher lacks advanced features found in more premium options, such as faster flow rates, advanced filter technology, or larger capacities.

The Clear20 pitcher impresses with its space-saving design and notably pleasant post-filtration taste, making it easy to want to stay hydrated. The filtered water's most striking feature is its undeniable "softness" in the mouth, offering a smooth and velvety texture unlike the dry sensation left by tap water. Its clean and neutral taste remained consistent even after a 15-minute resting period, making it distinguishable in a blind test.

We valued the wide pour-through lid for easy filling and cleaning, the user-friendly easy-pour spout, BPA-free materials, and a 48 oz. capacity (6 glasses). The TRUE LIFE™ Filter Indicator, signaling after 60 gallons, was a thoughtful addition. The filtration process was completed remarkably fast, taking just around a minute. However, securing the lid was slightly challenging, affecting the filling procedure. The lightweight but somewhat fragile pitcher required careful handling, and the handle design made it challenging to grip firmly. Despite lacking fancy features, the pitcher's efficient design exceeded our expectations, delivering softened, taste-free water and a reasonable price point, making it a standout choice. Moreover, the ability to attain a full pitcher of filtered water within three minutes was a notable advantage, considering other pitchers took longer for similar results.

Some users have reported issues with the lid design, which might not fit securely or could lead to spills during pouring.

The Aquasana Clean Water Machine stands as an excellent countertop choice, occupying minimal space while delivering pure and delightful-tasting water. Its cost-effectiveness in the long run, along with impressive filtration speed, makes it a top-notch option for water filtration.

During our tests, the unfiltered water had a slight metallic smell with hints of chlorine. However, upon using the Aquasana Clean Water Machine these odors vanished completely, affirming the effectiveness of its filtration system. Drinking this filtered water was a more comfortable experience, and we closely monitored our digestion in the days that followed. Fortunately, we had no digestive issues, and we gradually got accustomed to the taste, which differed from our usual Poland Spring water.

The filtered water felt remarkably soft and smooth in the mouth compared to the cloudy and aftertaste-laden unfiltered water. We especially appreciated the clean, slightly sweet taste of the filtered water, even though it took a while to adjust from Poland Spring. To enhance the taste, we added half a lime per gallon refill, which proved to be a clever trick. Setting up the Aquasana Clean Water Machine was a breeze, and though the design made pouring into larger bottles a bit inconvenient, it was overall user-friendly and efficient.

Replacing the filters can be pricey, so it might cost you more in the long run than you initially thought. Plus, buying the machine itself can be a bit expensive upfront compared to other similar options out there.

For those seeking a water filtration system with long-lasting filters, the AquaTru - Countertop Water Filtration Purification System is a top choice. The unfiltered water showed no smell but had an odd taste and appeared cloudy. In contrast, the filtered water was clear, smooth, and refreshing, devoid of any taste or smell issues, a significant improvement. While setup had its challenges due to unclear paper instructions, a helpful video guide made assembly relatively easy within 10-15 minutes.

Filter replacement was straightforward, aided by color coordination and a simple twist-lock mechanism. The filtration process took about 20 minutes, and an initial setup involved running it four times. Despite being a bit bulky, it didn't take up excessive counter space. Knowing when to replace the filters could be clearer, but its overall performance, especially its long-lasting, reasonably priced filters, makes AquaTru a worthwhile investment. The assurance of clean, great-tasting water makes it the go-to choice.

Its water tank is on the smaller side, so you'll find yourself refilling it often, which can be inconvenient. Plus, it's a big machine, taking up a chunk of your counter space.

We found the Brondell Cypress Countertop Water Filter System to be the easiest to use countertop water filter, providing substantial improvements. The tap water often had a strong chlorine smell, deterring us from drinking it as it resembled pool water. This changed when we tried the filtered water from Brondell Cypress—no smell or odor, a stark contrast to tap water. The absence of a chemical-like scent eased our consumption, and the taste was vastly improved due to the complete elimination of overwhelming chlorine.

Installation encountered a small hiccup due to faucet compatibility, but once resolved, it was quick and easy. The sleek, compact design fit neatly on our countertop, and its user-friendly nature made it stand out. The three filters lasting 6 months to a year provided convenience. Despite the initial cost, the Brondell Cypress proved a worthwhile investment, particularly for removing chlorine taste and its effortless operation. It also accommodated older family members due to its user-friendly features.

The Brondell Cypress Countertop Water Filter System, while efficient, can be challenging to install for those with non-standard kitchen sink setups.

Over the course of two weeks, we tested 24 water filters from leading brands to find the most efficient, user-friendly options that significantly enhance water taste, smell, and clarity. Throughout the 14 days, we tracked any efficacy or quality shifts. After our testing phase, we assigned ratings on a scale of one to five, with a higher score indicating superior performance based on these factors:

We spent over 336 hours testing water filters, and in the end the Brita Water Filter 10-Cup Stream Rapids Water Pitcher’s remarkable performance and user-friendly design exceeded our expectations, making it the best overall pick. We loved the price, quick filtration and easy handling, seamlessly fitting into sinks and fridges. We’ll keep our list updated as we test new products, so watch this space.

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.

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.

Water filter installation will vary based on the type of filter. Certain filters such as pitchers, countertops, water bottles, 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.

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 process removes most chemical contaminants such as bacteria as well as heavy metals like lead, arsenic, and cadmium.

Do I need to filter my tap water?

Deciding whether or not to filter your tap water depends on what contaminants are in your water, and whether or not you think it has an unpleasant taste or smell. Barnes tells us that most tap water is safe: "As a dietitian, I assure clients that most of our tap water from a public source is safe to drink. Unsure if your water is safe? You can find out from a water testing site in your area by calling the Safe Drinking Water Hotline at 800-426-4791."

What should I expect to pay for a water filter?

If you simply want to filter your drinking water, we recommend the Pur Plus Faucet Mount Water Filtration System, which rings up at just $22 and is easy to install on most kitchen sinks. If you're looking for a whole-house solution, like Express Water 3 Stage Whole House Water Filtration System, expect to pay between a few hundred and a couple thousand dollars—plus the cost of professional installation.
