Shower Head Water Filter — removable design, polyester fiber core, 20mm interface, wear-resistant PC construction Key benefits Cleaner water and fewer visible particles: the polyester fiber filter tightly captures suspended impurities common in hard water. Protects skin, hair and plumbing fixtures: reducing particulates helps limit residue buildup on skin, hair and shower components. Easy upkeep and long life: removable design allows straightforward filter replacement; durable PC material provides wear resistance for extended service. What it does and how it helps Filters impurities: the polyester fiber element traps dirt and particulate matter to improve water clarity at the point of use. Solves hard water issues: designed for use with hard water, it reduces suspended solids that contribute to scale and residue. Simple maintenance: the removable filter cartridge is easy to replace when performance declines, keeping the unit working well without complex tools. Key specifications and materials Filter media: polyester fiber filter for tight, mechanical filtration of impurities. Interface size: 20 mm connection — suitable for most faucets and showerheads that accept a 20 mm fitting. Housing material: wear-resistant PC (polycarbonate) construction for durability and long service life. Function: designed as a faucet/shower filter to improve water quality at the fixture. Compatibility and performance 20 mm interface makes this filter compatible with the majority of standard faucet and shower fittings that accept this size. Intended primarily to trap particulate impurities in hard water conditions; built for reliable, repeatable performance over time thanks to robust materials and removable cartridge design. Typical use scenarios Bathroom shower: attach to a compatible showerhead to reduce visible particles and minimize residue on skin and tiles. Kitchen or utility faucet: use on faucets with a 20 mm fitting to reduce suspended solids when rinsing produce or filling containers. Travel/RV or rental properties: quick-fit, removable filter provides a temporary improvement in water quality where plumbing varies and hard water is present. Maintenance notes Replace the polyester fiber cartridge when flow decreases or visible discoloration appears. The removable design keeps replacements quick and straightforward. Inspect the housing and fittings periodically; the wear-resistant PC material resists common wear for reliable, long-term use.
