Questions We Get a Lot
Reverse osmosis systems filter water at a specific point of use, like your countertop or under your sink, using a multi-stage membrane process to reduce dissolved solids and contaminants in your drinking water. Whole house filtration systems treat water at the point it enters your home, so every tap, shower, and appliance receives filtered water. The right choice depends on whether your priority is drinking-quality water at one source or cleaner water throughout your entire home.
Filtration and softening address different water quality concerns. Filtration targets contaminants like sediment, chlorine, and certain chemicals, while softening specifically addresses hard water minerals like calcium and magnesium that can build up in pipes and appliances. Some of our systems, like the 64,000 Grain Softener with Reverse Osmosis, combine both functions in one unit, which is a popular choice for homes dealing with both issues simultaneously.
UV water treatment systems expose water to ultraviolet light, which disrupts the DNA of microorganisms and is designed to support inactivation of bacteria, viruses, and cysts as water passes through the chamber. Our UV Whole House system features a stainless steel housing and a 1500-hour lamp rated for 12 GPM flow, making it a well-built option for households that rely on well water or want an additional layer of purification. UV treatment works best when paired with a pre-filter to address sediment before the UV stage.
We offer Free Shipping on Most Orders Within the Continental U.S. (Excludes AK/HI), and all purchases are covered by our 30-Day Returns policy. Because water filtration systems vary in size and installation requirements, we encourage you to review our full Return Policy page for complete details on eligibility and the return process before purchasing.
