Aquafilter FPCS1-L is a sediment filter made of polypropylene non-woven fabric (Melt-blown technology), made of 100% pure polypropylene. It filters mechanical impurities down to 1 micron: sand, silt, rust, and suspensions. Designed for SLIM/LONG 20" (20 x 2 1/2") housings. Operating range: 2-45°C. Recommended replacement: up to 6 months (depending onwater quality).
FPCS1-L Aquafilter 1 micron LONG 20" cartridge is an efficient filter cartridge for mechanical water filtration, designed for SLIM/LONG 20" housings. Made using Melt-blown technology from 100% pure polypropylene, it effectively removes mechanical impurities from water down to 1 micron, such as sand, silt, rust, and suspended solids. It is a practical water filter for residential and utility applications, supporting everyday water treatment and the operation of a larger water filtration system, including as a pre-filtration stage before more advanced solutions.

Aquafilter FPCS1-L is a polypropylene nonwoven cartridge designed to remove solid contaminants from water. It is manufactured using Melt-blown technology, which enables effective filtration while maintaining good flow and low pressure drop. The filtration material is 100% pure polypropylene, without additives.
The cartridge captures all types of mechanical impurities down to 1 micron. As a result, it effectively traps sand, silt, rust, and suspended solids, improving the quality of water directed further into the installation, fittings, household appliances, or subsequent filtration stages.
The FPCS1-L model is designed for SLIM or LONG housings for cartridges with a height of 20 inches and a diameter of 2 1/2 inches. This means compatibility with the popular 20 x 2 1/2" standard.
Housings of this type are often installed on main water connections in single-family homes. In practice, this cartridge performs well wherever effective pre-filtration is needed while maintaining reasonable operating costs.
Water filtration using SLIM cartridges provides sufficient performance in most cases, while also allowing the system to remain economical to operate.
The 1 micron mechanical cartridge can serve as an effective pre-filtration stage in cold water systems. It helps reduce the passage of sediment into further system components, which can support the proper operation of taps, valves, fittings, and devices connected to the water supply network.
This type of filter cartridge is also used as pre-filtration before solutions such as a reverse osmosis filter, osmotic filter, reverse osmosis, or an advanced reverse osmosis system, because it limits the inflow of mechanical contaminants to subsequent treatment stages.
Important: the recommended cartridge replacement interval is up to 6 months. Actual service life depends on the quality of the incoming water and the amount of contaminants retained. In the event of a noticeable drop in flow or heavy fouling, the cartridge should be replaced earlier.
Regular cartridge replacement helps maintain high filtration efficiency and stable system operation. The polypropylene cartridge is not intended to improve the taste or smell of water, but to mechanically remove solid particles that may cause scale buildup and accelerated wear of installation components.
Thanks to the 1 micron filtration rating, the FPCS1-L model performs well wherever very good protection against fine mechanical contaminants is expected, while maintaining ease of use and favorable operating costs.

It is a sediment cartridge intended for mechanical water filtration. Its purpose is to retain fine solid impurities such as sand, silt, rust, and suspended solids, with a filtration accuracy of 1 micron.
The cartridge retains mechanical impurities, including sand, silt, rust, and suspended solids present in water.
The FPCS1-L model fits SLIM or LONG housings designed for cartridges with a height of 20 inches and a diameter of 2 1/2 inches, i.e. in the 20 x 2 1/2" standard.
The cartridge is made of polypropylene nonwoven fabric using Melt-blown technology. The filtration material is 100% pure polypropylene, without additives.
The recommended replacement interval is up to 6 months. The exact service time depends on water quality and the amount of mechanical impurities the cartridge retains during operation.
The operating temperature range is from 2 to 45°C, so the cartridge is intended for typical cold water system applications.
No, one of its advantages is low pressure drop combined with very good dirt and sediment retention capability.
Yes, the 1 micron mechanical cartridge can be used as a preliminary stage before water treatment systems, including osmotic filters and reverse osmosis systems, because it limits the inflow of mechanical contaminants to subsequent filtration stages.
