Brand Name: NONE

Dual-Precision Filtration: This 20-inch spiral-wound sediment filter features a spiral-wound structure and offers two filtration precision options: 1 micron and 5 microns. The 5-micron option is suitable for pre-filtration of high-particulate water sources, while the 1-micron option is suitable for fine end-point filtration, fully meeting your different water quality needs. It effectively filters most particulate matter in water.

Food-Grade Material: Our 1/5-micron sediment filter cartridge is made of food-grade polypropylene fiber. This cartridge is suitable for household drinking water and under-sink water purification systems and will not alter the original taste of the water.

High-concerned chemical: None

Longer Lifespan and More Stable Water Flow: Utilizing spiral-wound technology, the fiber density of this 20-inch cartridge gradually increases from the outside in, achieving three-dimensional deep filtration. This effectively reduces the frequency of cartridge replacement and lowers long-term operating costs.

Origin: Mainland China

Type: Water Filter Parts

Versatile and Easy to Replace: This 20-inch spiral-wound filter cartridge is compatible with 20-inch filter housings and is suitable for most mainstream whole-house water purification systems, reverse osmosis pre-filtration units, commercial water purification equipment, and high-flow water purifiers. It can directly replace existing filter cartridges of the same size, effectively reducing replacement costs.

Wide range of applications: This universal wound filter cartridge is widely applicable to various scenarios, including whole-house central water purification, reverse osmosis system pre-filtration, under-sink drinking water filtration, villa water supply systems, commercial and catering drinking water treatment, agricultural irrigation and industrial circulating water filtration, etc.
