After more than 10 hours of research and 20 hours of testing, our top pick goes to the ZeroWater ZP-010. It offers the best combination of filtration power (5 stages), solid capacity (10 cups) and a water quality meter to detect purity levels.
Its 5-stage water filtration is very impressive, using a coarse filter screen, foam distributor, carbon/oxidation filter, ion exchange resin, and an ultra-fine screen to eliminate particles of all sizes, as well as eliminate odors and improve the taste. It offers more intensive filtration than standard carbon filters. The best products always go the extra mile. For instance, check out the best air fryer that comes with additional functionalities.
Some contaminants the ZeroWater system removes include iron, lead, mercury, zinc, and copper along with inorganic particles such as cyanide and chlorine. Note, its filtration is much slower than fewer-stage filters on the list given the number of filters. It is a better option for those who filter their water well in advance of most meals and not among the best water filters for camping.
Its slim design is a plus, measuring only 10.47 inches by 5.67 inches by 14.37 and weighing less than 4 pounds, making it a solid addition to your countertop or dining area. Bonus points go to its spigot, which offered some of the smoothest pouring we tested. No black flecks were observed at any point, common when using other water filters for the first time.

During testing, it took nearly 1 minute for the water to bypass all filters and fill the pitcher. Readying the Everyday is also a breeze, only requiring a simple rinse of the standard or Longlast (not included) filter with cold water for 15 seconds before inserting it into the filter and pressing firmly to seal it in place.
A filter change indicator lets users know when it is time to replace the filter, with a large “Replace” reminder beside a blinker. It also easily resets by holding and activating the status button for 2 seconds for a standard filter or 6 seconds for a Longlast filter.

Waterdrop’s filtration system is also compact, consuming 1/4 space of our top pick, the Brita White Ultramax which needs no extra space on countertops. Watch its faucet compatibility though – it is only compatible with standard faucets, not fancier hand-held or pull-out style models.
Each water pitcher also contains several layers of filtering, including mesh screens on top, activated carbon in the middle to absorb impurities such as chlorine, and an ion-exchange resin that reduces hardness in water. Note, this uses a standard filter, not the Longlast filter of our #5 pick which eliminates more contaminants, removes 99 percent of lead, and has a longer life.
Filter life is strong, with 1 filter equivalent to approximately 300 16.9 oz plastic bottles. While filtering for the first time during testing, no black flecks are observable, which are fine carbon residue particles accumulated during the manufacturing process.
