    I looked around for years for a passive filter system that was large enough for a whole house filter. I didn't want a high maintenance system. And the so-called whole house filters from big box stores are a joke. I luckily found Aquasource. I installed one of these several years ago and have loved it. The whole house is chlorine and sediment free. I haven't had to change the refrigerator filter in years. Within just days, I could tell a difference on my skin. As a former master plumber, I couldn't get over how high the quality of this product is. It is worth the cost.

Benefits & Features

The benefits and features of the Aquasource whole house water filter system include:
  • Whole House Water Filtration – The water at every tap in your home will taste and smell better – no chemical odor of chlorine or chloramine, and no tastes or odors from particulate matter in your tap water. You will enjoy cleaner water coming out of every sink, shower, bathtub faucet, or other water-using appliance. This means cleaner water not just for your kitchen or bathroom, but also cleaner water for your dishwasher and cleaner water for your laundry. Because the Aquasource connects at only the water’s entry point to the house, you only have to maintain one system with replacement cartridges to maintain optimal performance.
  • Filtration and Flow Rate - Filtered water does you little good if it lowers the water pressure too much to use conveniently. Multipure’s Aquasource has a unique, multi-filter-cartridge design that can filter your water while still maintaining a reliable, high-flow water pressure.
  • Even More Filtering Options – The standard Aquasource configuration gives you powerful chlorine filtration throughout the house, and reduces the presence of rust, dirt, sand, algae, and other particulate matter in your water. We also offer several options to meet your specific whole house water filter needs. In municipalities that use chloramine instead of chlorine as the disinfectant additive, you can configure your Aquasource to reduce the presence of chloramine in your tap water. If hard water and limescale buildup is a problem with your plumbing, you can configure your Aquasource to include a limescale inhibitor, reducing the damaging buildup in your pipes. You can find the perfect Aquasource whole house water filter to meet your family’s needs.

How a Whole House Filter Helps You

Naturally, you can expect healthier, cleaner water when your water is properly filtered. But have you considered all the ways a whole house water filtration system helps you and your family? They include:

  • Better water for your dishwashers, washing machines, ice makers, and any other water-using appliances.
