A countertop ultrafiltration water filter system uses an Ultra-Filtration (UF) hollow fiber membrane to effectively remove contaminants in the water, allowing only pure water and total dissolved minerals to pass through.
Comparison of the best countertop ultrafiltration water filter system
Ultra-Filtration (UF) hollow fibers membrane has a pore size designed to remove contaminants such as bacteria, viruses, cysts, and suspended particles.
There are two types of UF countertop water filters. The system rests on the counter without being connected to a tap or faucet, as well as the system that uses a diverter valve or adapter to connect directly to your existing kitchen tap/faucet.
How does Countertop ultrafiltration water filter system work
The Countertop UF water filter system has two storage tanks (top and bottom) that sit on the kitchen sink tops, tabletops if you prefer room temperature water, and in the refrigerator, if you prefer cold water.
The top storage tank is where you add untreated water from the tap, and the bottom storage tank is where filtered water is stored, ready for human consumption.
Read the differences between ultrafiltration and reverse osmosis
Once you add untreated water to the top tank, gravity pushes water through the filter between the two tanks. All contaminants are removed, and the bottom reservoir holds filtered water ready for human consumption.
After adding untreated water to the top tank, gravity drives water through the filter between the two tanks. The filter will eliminate all, and the bottom reservoir now holds filtered water safe to drink.
If you’re using a diverter to connect to the faucet, the water flows through the filter, which removes all impurities, and the adaptor lets you choose between filtered and unfiltered water with ease.
