Fresh, Clean Drinking Water for Pennies per Gallon!


The Multipure Aquaperform Inline model is one of the most technologically advanced water treatment devices available, providing the BEST in performance – reduces all of the contaminants that the other Multipure Drinking Water Systems do, PLUS ARSENIC!

The Multipure Aquaperform Inline model is a highly effective drinking water filtration system that installs inline and provides convenient access to fresh, clean drinking water whenever you want it. The Aquaperform Inline is designed to be installed under the counter and used for inline applications such as for icemakers, hot water dispensers, water fountains, coffee machines, various restaurant uses, and more. The versatile filtration unit housing can be mounted out of sight on the cabinet wall, or set on the cabinet floor using an optional plastic base (not included), and it ships to you with a mounting bracket for attaching the housing to a cabinet wall.

The Aquaperform uses Multipure’s unique solid carbon block filter technology, which is considered to be the most effective method for reducing a wide range of contaminants of health concern that may be present in your local water. The carbon is compacted into a dense structure, causing every molecule of water to be forced through microscopic pores of carbon, effectively reducing pollutants. The solid carbon block water filter is a replaceable cartridge designed so that it may be easily changed. The solid carbon block water filter does not waste water, there is no electricity required, it does not remove essential trace minerals that are beneficial to good health, it does not add salt or silver to the water, and it provides fresh, delicious, healthy drinking water. You can trust that the Aquaperform will deliver clean water as promised because the Aquaperform is tested and certified by NSF International against stringent performance standards. The Aquaperform reduces all of the contaminants that the Multipure Aquaversa drinking water systems do as well as reducing Arsenic V. 

This filter system previously was identified as Multipure model MP880SI.
