"The best quality filters. I will keep buying and recommending too. Made in USA. Great customer service to boot!"
— Ernest M. (5/5)
"We use this as an integral part of our freshwater system on a houseboat at Lake Powell. It's in series just after with a US Water Systems sediment filter and just before a UV disinfection light. We trust that set-up. Never have had a problem with these filters or with the safety of the water this set-up systems produces. AND this filter is made here in the USA. I just can't in good conscience use a foreign-made filter when friends and family are depending on having safe drinking water on my boat."
— Unc M. (5/5)
"I promptly received all of the replacement items including new filters and water tank. The bladder must have burst because the water tasted stale. Replacement was relatively straight forward and the water now tastes fresh and tasty."
