Compact Under Sink Reverse Osmosis Water Filtration System - AOS-HERO-CHR

The AO Smith Under Sink Reverse Osmosis Water Filtration System offers a comprehensive solution for delivering clean, healthy tap water to your home. This advanced filtration system is independently tested to meet NSF standards 42, 53, 58, and 401, ensuring the removal of up to 99% of 90 contaminants, including fluoride, chlorine, chloramine, lead, arsenic, pesticides, PFOA/PFOS, cysts, microplastics, and more.

Featuring a dedicated faucet with a chrome air gap design, the system prevents backflow into the filtration components by draining water out of the air gap hole on the side of the faucet. This smart feature ensures the continuous flow of clean water in your kitchen, while the short, direct, and unobstructed drain line allows for efficient drainage.

One of the standout features of this system is the ease of filter replacement. Simply twist out the used cartridge and replace it with a genuine AO Smith replacement filter to maintain contaminant removal performance. The included first set of filters, RO tank, faucet, and all necessary parts for under-counter installation make the initial setup a breeze.

The system offers different models to cater to various household needs. The AOS-HERO-CHR is designed for under-sink dedicated faucet installation, the AO-MF and AO-MF-ADV models are suitable for under-sink use with existing faucets, and the AO-US-200 is a whole-home point-of-entry solution. Each model is engineered to meet specific certification standards, ensuring optimal contaminant reduction and water quality.

For instance, the AOS-HERO-CHR is certified to standards 42, 53, 58, and 401, removing a wide range of contaminants, including chlorine, fluoride, chromium, and more. The AO-MF and AO-MF-ADV models are certified to standards 42 and 53, targeting chlorine, lead, atrazine, and lindane, while the AO-US-200 is certified to standards 42, 43, and 401, with the additional P473 certification, addressing lead, mercury, chlorine, and more.

Each model also offers varying scale control capacities, flow rates, and recommended household sizes, ensuring you can choose the perfect system to meet your specific water filtration needs.

To ensure a seamless installation and operation, the system comes with helpful troubleshooting guides. These guides address common questions, such as how to know if the tubing is connected correctly, why water may be leaking from the drain saddle, whether the system is supposed to make noise, and what to do if the water appears black during initial use.

Overall, the AO Smith Under Sink Reverse Osmosis Water Filtration System provides a comprehensive and efficient solution for delivering clean, healthy tap water to your home, with a focus on ease of use, advanced filtration, and reliable performance.
