Independently tested to reduce bacteria and viruses from your water so every drop of tap water is fresher, safer and more pure⁶.
Tested to remove certain heavy metals and industrial pollutants including lead, cadmium, and chromium III by over 90%⁶.
Designed with BPA-free materials⁷ and certified to NSF 372 standards for lead-free materials⁷.

High-capacity filtration system can produce the equivalent of over 3,000 water bottles (16.9 fl oz) or 1,000 water pitchers (48 fl oz) per day⁸.
One of the few tankless, reverse osmosis water filtration brands to be independently certified for durability, quality and safety by the Water Quality Association (WQA).
Intuitive interface and filter lifetime indicator reminds you when and which filter needs to be replaced, making maintenance a breeze.
Pureit’s unique DURAViva technology maintains filtration and flow rate performance and reduces clogging.
Even when tested in harder water conditions, Pureit water filtration systems can produce up to 30% more clean water, maintaining filtration and flow rate with minimal drop off over their lifespan².
The space saving, tankless design is up to 40% more compact than many RO tank water purifiers. It fits discretely under your sink so you can have pure water without sacrificing space.
Eliminate the long wait for filtered water. Our system is designed to provide a consistently fast flow rate of water — so you can fill a 6oz glass with purified water in just 12 seconds¹.
Engineered to provide high performance that does not fade, so your family can have more pure water for longer.
