The Multipure Aquaperform Under Sink Water Filter System is recommended for anyone who prefers a water filter that is to be installed under the counter, and which filters Arsenic V in addition to the other 65+ contaminants our other filters are NSF Certified to reduce.
The Aquaperform is the ultimate Multipure carbon filter system. It is the ONLY carbon block filter available anywhere that is certified by the NSF to reduce Arsenic! With many cities having rather high levels of arsenic, higher than the State and Federal goals, this is the best filter for your family if you want to drink the healthiest, safest filtered water while keeping the healthy minerals in your tap water. It filters all the same contaminants our other carbon block filters do, with the added ability to filter Arsenic V. To learn more about Arsenic levels in tap water please see our Arsenic page.
Note that all our water filters have the same basic carbon block filter except for this one which also filters arsenic v, and the AquaRO Reverse Osmosis system for those who want to filter more impurities at the expense of also removing the healthful minerals.
There is no difference between the Aquaperform countertop, under the counter and Inline models in terms of filtration ability, they only differ in where and how they are installed in your kitchen.
