Brands that plan the refill SKU at launch, with its own barcode, pack count and shelf position, build a repeat-purchase line rather than a one-off accessory. ZHONGHE lists its cartridges as standalone catalog items so refills can be ordered independently of the shower heads they fit. The four cartridge types map to the four media in the factory's filter range. Activated carbon fiber carries SGS chlorine data (99.5% free-chlorine removal at the start of flow). PP cotton traps rust and sand. Mineral bead cartridges hold calcium sulfite balls (16-item hygiene test, RoHS screened) and metasilicate media (reference pH 8.1, REACH SVHC checked). The magnet cartridge is a conditioning accessory. ## Fit, sizing, and private label packs Cartridges are dimensioned to the chamber of a specific handle family, so a refill program starts from the shower head model number. When a buyer's existing shower head comes from another supplier, sending a photo and the cartridge dimensions lets the factory check whether an existing cartridge fits or whether a dedicated housing is needed. Refills are packed in single or multi-packs. Retail color boxes suit shelf sales, brown boxes and polybags suit marketplace subscriptions, and bulk cartons suit importers who repack. Custom packaging is discussable from 2,000 units. ## Ordering cartridges with or without shower heads State the shower head model or cartridge dimensions, the media, the pack count, the packaging format and the quantity. Cartridges can be added to a shower head order or shipped alone as a refill replenishment. Every shower head unit is water tested before packing; cartridges are checked for fill, seal and housing condition during packing. ## FAQ ### Who manufactures replacement shower filter cartridges?
