High-Efficiency Under Sink RO Water Filtration System for Home Use

Clean, healthy tap water can be achieved by reducing up to 99% of 90 contaminants, such as fluoride, chlorine, chloramine, lead, arsenic, pesticides, PFOA/PFOS, cysts, microplastics, and more, from the water in your house.

The advanced filtration system of this under-counter reverse osmosis filter has been independently tested and meets the rigorous NSF standards 42, 53, 58, and 401.

To ensure that water in your home's kitchen continues to flow smoothly, a dedicated faucet with a chrome air gap is provided. This faucet prevents backflow into the filtration system by draining the water out of the air gap hole on the side. It is important to make sure the drain line is short, direct, and unobstructed.

Replacing the filters is a breeze. Simply twist out the used cartridge and replace it with a genuine AO Smith replacement filter for ongoing contaminant removal. It is important to use only certified AO Smith replacements to maintain the efficacy of the system.

The package includes the first set of filters, a RO tank, faucet, and all the necessary parts for easy under-counter installation.

For filter replacements, use the genuine AO Smith replacements AOS-HERO-S1S3 (B0CCQ9TKMM) and AOS-HERO-S2 (B0CCQCNDLK). Choosing genuine replacements ensures the continued effectiveness of the system.
