UF Filter

A UF (ultrafiltration) filter forces water through a semi-permeable membrane with microscopic pores. It removes suspended solids, bacteria, viruses and other microorganisms, and keeps the minerals.

How UF works

Key characteristics

Pore size

0.01 to 0.1 microns: fine enough to block most harmful microorganisms while water and dissolved minerals pass through.

Mechanism

Works on ordinary home water pressure to push water across the membrane.

Function

A physical barrier that reduces turbidity (cloudiness). It does not remove dissolved salts (TDS).

No electricity

Unlike RO, a UF filter needs no power, so it’s cost-effective and energy-efficient.

Keeps minerals

Unlike RO, UF retains the essential minerals that are good for health.

What a UF filter removes

Microorganisms: bacteria, cysts and most viruses
Particulate matter: suspended solids, colloids, silt and other large particles
Other contaminants: algae, protozoa and some organic molecules

Where it’s used

Before RO: protects the delicate RO membrane from fouling and extends its life
Drinking water: standalone purifiers for low-TDS municipal water where germs are the main concern
Wastewater and industry: municipal treatment, juice clarification and pharmaceuticals

UF compared with other methods

UF vs microfiltration (MF)	UF has smaller pores and removes more contaminants, including viruses that MF would miss.
UF vs reverse osmosis (RO)	RO’s much smaller pores (0.0001 micron) remove dissolved salts, but also strip minerals and use more energy. UF suits low-TDS water where you want to keep minerals.
