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).
This ensures that the product is constructed from safe materials, the claims listed on the packaging are backed by test data, and the product quality will be maintained under normal use conditions.
Through a combination of high-quality reverse osmosis (RO) and carbon filters with anti-scaling materials, Pureit’s proprietary DURAviva filtration technology provides more clean water for longer.

5 Series UR5640 RO Water Filtration
Our highest capacity product, the UR5640 can produce the equivalent 4,300 water bottles (16.9 fl oz) or 1,500 water pitchers (48 fl oz) in a single day.* It also provides our fastest flow rate making it the perfect solution for larger households who need to access more water without the wait.
5 Series UR5440 RO Water Filtration
All the performance of the UR5640 model but scaled down for smaller households. The UR5440 model can still deliver over 2,900 water bottles (16.9 fl oz) or 800 water pitchers (48 fl oz) per day , all in one simple unit.
Pureit's DURAViva technology uses 3 primary filters to provide 5 layers of filtration to reduce germs,
bacteria. It's also been tested to remove over 90% of total dissolved solids (TDS) like calcium,
magnesium, and potassium, as well 99% heavy metals like lead, chromium III, and cadmium¹.
30% more clean water³
Pureit’s unique DURAViva filtration technology uses a combination of anti-scaling materials and premium RO and carbon filters to maintain filtration and flow rate performance and reduce clogging.
Even when tested in harder water conditions, Pureit water purifiers can produce up to 30% more clean water, maintaining filtration and flow rate with minimal drop off over their lifespan⁴.
Pure, fresh water without the wait
Conventional reverse osmosis systems use a tank to store purified water and require a longer waiting time before water is dispensed.
Pureit 5 Series tankless water purifiers are designed to produce a constant fast flow rate of fresh purified water, so you can fill a 6oz glass in just 8 seconds.
The modern, tankless design is up to 40%
more compact than many RO tank water
filtration systems. It fits discreetly under your sink so you can have pure water without sacrificing space.
Change filters in just four simple steps with our snap out, snap in filter replacement.
The integrated water board is intelligently
designed to guide the flow of water using
fewer connection points than traditional tank RO systems, providing better quality water flow and reducing the chance of leaks.
Engineered to provide high performance that does not fade, so your family can have more pure water for longer.
