High Capacity Water Filtration Throughout Your Home


The Multipure Aquasource is an effective water treatment solution for your whole house, providing powerful filtration at the point of entry, and ensuring that every water outlet in your home delivers cleaner, more healthful water. The Aquasource installs in the garage or basement as a fixed-location filtration element. An array of three solid carbon block filters working in parallel ensures that the filter reduces the presence of contaminants while maintaining the high water pressure needed to supply all the sinks, baths, and showers in your house.

Due to its bulk and weight, this product is available for sale only for ship-to locations within the continental U.S. The shipping price will be adjusted by Multipure to your specific shipping address during order processing. The actual amount charged to your credit card for shipping very likely will be lower than the “worst case” shipping fee automatically added to your order during checkout.

* The Aquasource has not been performance tested by an independent laboratory, and the manufacturer makes no claims for the reduction of contaminants of health concern.

  • Designed for permanent installation in a sheltered location within the home basement or garage.
