Filtration element USTM PS Protect 10" 5 micron — 10 x 2.5" polypropylene, antibacterial zinc additive

USTM PS Protect 10" is a mechanical polypropylene filter cartridge with an antibacterial zinc-based additive, designed for pre-filtration of potable water. The element features a 5‑micron nominal rating and a gradient structure that traps larger particles on the outer layers and finer particles toward the centre. Built for compatibility with standard 10 x 2.5" housings, the cartridge is suitable for applications where removal of sand, silt and rust is required while maintaining water safety for food-contact uses. The element is certified to NSF standards and is intended for continuous household and light-commercial water treatment where moderate flow and low pressure drop are needed.

Advantages

The polypropylene construction ensures chemical resistance and mechanical stability, while the gradient-wound structure provides effective particle capture with lower initial pressure drop. The zinc-based antibacterial additive reduces bacterial growth on the cartridge surface, extending service life under typical conditions. The 5‑micron rating balances sediment removal and flow capacity, allowing maximum flows up to 25 L/min with an approximate pressure loss of 0.2 bar at recommended conditions. The cartridge is suitable for food-contact water treatment and withstands operating temperatures up to 40°C.

Suitable for

• Pre-filtration of drinking water in household filter housings (10 x 2.5")
• Removal of sand, silt and rust from municipal or well water
• Use in point-of-entry or point-of-use sediment filters before activated carbon or membrane stages
• Food-service and light commercial applications requiring food-contact compliance

Key specifications

How to use

Install the USTM PS Protect cartridge into a compatible 10 x 2.5" filter housing following the housing manufacturer’s instructions. Ensure proper orientation and that housing O-rings and seals are intact to prevent bypass. Flush the new cartridge with water for a short period until the water runs clear before connecting to downstream appliances. Monitor flow rate and water clarity periodically; replace the cartridge when flow decreases significantly, the pressure drop increases, or after the estimated service life is reached.

Usage recommendations

For optimal performance, pair this sediment cartridge upstream of activated carbon or membrane filters. Do not use with hot water above 40°C. Replace the cartridge sooner in cases of high sediment load or reduced flow. Observe local regulations for food-contact water systems and perform regular maintenance on housings and seals.
