Frequently Asked Questions


1. What is an ultrafiltration drinking water system?
An ultrafiltration (UF) drinking water system is an under-sink filtration system that uses an ultra-fine membrane to filter drinking water. It can reduce bacteria, viruses, microorganisms, sediment, chlorine, chloramines, odors, tastes, and other impurities while allowing naturally occurring minerals to remain in the water.

2. What is the difference between ultrafiltration and reverse osmosis?
The main difference is that ultrafiltration allows naturally occurring minerals to remain in the water, while reverse osmosis significantly reduces many dissolved minerals and contaminants. UF also operates as a full-flow system without a storage tank, making it a convenient option for homeowners who want filtered drinking water while retaining minerals.

3. What does an ultrafiltration water filter remove?
The Pristine Water UFF system uses three stages of filtration to reduce sediment and particulate matter, chlorine, chloramines, tastes, odors, VOCs, PCBs, nitrates, bacteria, viruses, and other microorganisms. Actual filtration performance depends on the specific contaminant and water conditions.

4. Does an ultrafiltration system need a storage tank?
No. The UFF drinking water system is a full-flow under-sink filtration system, so it does not require a bulky storage tank. It connects to the home’s cold-water supply and provides filtered drinking water through a dedicated faucet.

5. How often do ultrafiltration water filters need to be replaced?
Filter replacement depends on water quality, household usage, and the condition of the cartridges. The UFF system uses quick-change cartridges that are designed to make replacement simple. After replacing the filters, they should be flushed before drinking water is used.

6. Is ultrafiltration a good alternative to bottled water?
Yes. An under-sink ultrafiltration system can provide convenient filtered drinking water directly from your kitchen faucet, reducing the need to purchase, transport, and store bottled water. It can also improve the taste and odor of drinking water while leaving naturally occurring minerals intact.
