Complete set of pre-filters for the USTM Silver reverse osmosis system. It includes a mechanical filter PS5 (PP fiber 5 µm) and a block carbon filter BL10 made from activated coconut carbon. A quick service kit, recommended replacement every approximately 6 months or after filtering up to 8,000 liters (depending on water quality). It protects the subsequent filtration stages and improves the taste and smell of the water.
The RO Silver USTM set of pre-filters is a practical service kit for a reverse osmosis system, designed for quick replacement of the basic cartridges responsible for protecting the later filtration stages. This reverse osmosis set includes a PS5 mechanical cartridge and a BL10 carbon cartridge, helping the water filtration system operate efficiently, protecting the osmotic membrane and improving the taste and odor of the water. It is a convenient solution for users who want to keep the USTM Silver osmosis filter performing at a high level during regular servicing.

The set has been prepared with quick and hassle-free replacement of pre-filters in the USTM Silver system in mind. Regular servicing helps maintain high water treatment efficiency, reduces the risk of overloading subsequent filtration stages, and supports stable operation of the entire system.
The recommended replacement interval is approximately every 6 months or after filtering up to 8,000 liters of water, depending on the quality of the incoming water and operating conditions. Thanks to this, a water filter operating as a reverse osmosis system can maintain proper efficiency and safe use.
The PS5 cartridge is responsible for retaining solid contaminants present in the water. It removes particles such as sand, silt, and rust, thereby protecting the next filtration stages from excessive load. This is especially important in installations where the reverse osmosis filter operates regularly and is expected to provide stable water quality over a long time.
A filtration accuracy level of 5 µm helps protect the downstream components of the system and also extends the service life of the membrane, which is a key component of every reverse osmosis system.
The BL10 cartridge, made of activated coconut shell carbon, is responsible for improving the organoleptic parameters of water and reducing selected chemical contaminants. It effectively reduces chlorine content, chlorine-like solvents, and most pesticides.
In practice, this translates into a clear improvement in the taste and smell of the water, as well as better operating conditions for the later filtration stages. In systems such as reverse osmosis, a properly functioning carbon cartridge is essential for protecting the osmotic membrane from the negative effects of chlorine.
Regular replacement of the pre-filters helps maintain clean water and trouble-free operation of the USTM Silver system. The service frequency should be adjusted to the actual water quality and intensity of use.
The set is intended for small service of the USTM Silver system. It is a solution for users who want to efficiently renew the basic filtration stages without unnecessary downtime and without having to select compatible cartridges on their own.
The set works well as a standard maintenance element of a home water filtration system. Timely replacement supports proper water treatment, protects key components, and helps maintain the expected quality of drinking water.

The set is intended for the USTM Silver system and is used for small-service replacement of the pre-filters.
The set includes two cartridges: PS5, a mechanical cartridge made of polypropylene nonwoven with a filtration accuracy of 5 µm, and BL10, a block carbon cartridge made of activated coconut shell carbon.
The recommended replacement interval is approximately every 6 months or after filtering up to 8,000 liters of water. The exact frequency depends on water quality and intensity of use.
The PS5 cartridge retains solid particles such as sand, silt, and rust. This protects the next filtration stages and supports longer membrane service life.
BL10 reduces chlorine, chlorine-like solvents, and most pesticides. It also improves the taste and odor of the water.
Yes, properly functioning pre-filters help protect the osmotic membrane. The mechanical cartridge limits the inflow of solid contaminants, and the carbon cartridge supports chlorine reduction, which can negatively affect the membrane.
The dimensions given for the set are 10″ × 2½″.
The operating temperature range is from 2 to 42 °C.
Regular servicing helps maintain high filtration efficiency, improves the taste and odor of the water, protects subsequent stages of the system, and supports trouble-free operation of the entire USTM Silver system.
