If the absolute purest water you can get from a pitcher is your top priority, the ZeroWater ZP-010 10-cup is a top choice. It's NSF certified to reduce lead, and, in testing, removes an impressive amount of both lead and other contaminants, without clogging. The 10-cup capacity is a good fit for a couple or a small family. An included meter measures the amount of dissolved solids in your water, It's a gravity-based filtration system, so is a bit slow, but produces provably pure water.Buy for $28.09
The Culligan Faucet Filter FM-15A is easy to install and convenient to use, reviewers say, automatically turning the filter off when the water stops flowing. In professional tests the 15A removes lead and organic compounds, and owners notice a marked improvement in the taste of their water. This is one of the best values in a water filter, with a low initial cost and low filter costs as well. The most common complaint about this unit is its very slow flow rate.Buy for $17.67
One of the most popular uses of water filters is to remove fluoride from drinking water, but very few water filters outside of reverse osmosis actually do that. The exception is the Home Master TMJRF2 Jr F2 Counter Top Water Filtration System. The activated alumina filter removes up to 93 percent of fluoride -- as high as that claimed by some reverse osmosis systems. However, unlike RO systems, the Jr F2 does not remove beneficial minerals like calcium and magnesium.Buy for $85.00
It's not included in any professional roundups, but owners say the iSpring RCC7 Reverse Osmosis Water Filter System is a top performer. This under-sink filter is easy to install, even for those with little plumbing knowledge. Most importantly, it produces excellent-tasting water and is very affordable compared to similar systems. iSpring claims that its 5-stage filtration process removes 1,000+ water contaminants. As expected at this price point, the iSpring gets complaints regarding its plastic construction. Customer service is based in the U.S. and is very responsive.Buy for $199.99
