Cuno Water Filters vs. Aqua-Pure Water Filters vs. 3M Aqua-Pure Water Filters vs. 3M Water Filters vs. KleenWater Compatible Filters
3M Cuno Aqua-Pure makes water filters and cartridges for home or business. Our KleenWater product line includes quality compatible replacement cartridges, water filters, reverse osmosis systems and hot water protectors for less.
Cuno had long been a leader in liquid filtration and 3M decided to buy them in May of 2005. Cuno's had a reputation as a manufacturer of high quality commercial and home filtration products which was a great complement to 3M's existing air filter and liquid purification products.
3M gradually phased out the Cuno name while continuing to sell under both the Aqua-Pure and 3M names. Currently the same water filters are being sold under 3M filters and Aqua-Pure filters with different model numbers.
