Create a dedicated source of purified water right at your sink with the AquaTru Under Sink Water Purifier. This bundle includes the full Under Sink system, a starter filter set, and an additional 2-year filter pack so you can enjoy consistently clean, great-tasting water with long-term convenience.

Designed for households that use a lot of water throughout the day, the AquaTru Under Sink connects directly to your cold-water line and comes with a sleek faucet that allows you to fill glasses, bottles, cookware, or kettles with ease. With its 4-stage Ultra Reverse Osmosis purification, it removes contaminants such as lead, arsenic, PFAS, fluoride, chlorine, and nitrates. The result is reliable, high-quality drinking water on demand.

A starter filter set is already included with your unit. With the extra 2-year filter pack in this bundle, you have all the replacement filters you need for a total of 2.5 years of use.

AquaTru Under Sink + 2 years of filters
This bundle includes the complete AquaTru Under Sink system with a starter filter set, plus a 2-year filter pack containing 4x pre-carbon filters, 2x VOC carbon filters, and 1x reverse osmosis membrane. After the first 6 months, your pre-carbon filter will need replacement. With the included filter pack, you have everything required for smooth, uninterrupted filtration for the following 2 years. This ensures you always have clean, purified water ready at the faucet without the need for frequent purchases.
