10 Inch Universal Water Filter Replacement 3-Stage Set PP Cotton GAC Carbon Block for RO System

Give your home water purifier a dependable pre-filtration upgrade with this 10 inch universal 3-stage filter replacement set. Designed as the first line of defense before the RO membrane, these cartridges capture large particles and reduce chlorine and odors to keep your reverse osmosis system performing at its best. What's Included: - 10 inch PP cotton filter: Made of melt-blown polypropylene with a graded density structure that traps sediment, rust, sand and suspended solids. - 10 inch granular activated carbon (GAC) filter: High-porosity carbon effectively reduces chlorine, discoloration and certain organic contaminants. - 10 inch carbon block (CTO) filter: Sintered at high temperature for a stable structure that resists carbon fines, further reduces chlorine and chemicals, and helps protect the downstream RO membrane. Fit and Installation: Standard 10 inch size fits most 10 inch filter housings, 3-stage pre-filters and home RO water purifier accessories. Before installation, shut off the water supply, drain the housing, unscrew the cap and replace the cartridge. Make sure the O-ring is properly seated to prevent leaks. Flush for 10 to 15 minutes before regular use. Replacement Schedule: Replace the PP cotton every 3 to 6 months depending on water quality and usage. Replace the GAC and carbon block filters every 6 to 12 months. If you notice reduced flow, changed taste or a visibly dark cartridge, replace it promptly to maintain filtration performance and extend RO membrane life. Ideal Applications: Home RO water purifiers, reverse osmosis systems, kitchen water filtration units and commercial drinking water equipment with standard 10 inch housings. Whether for daily drinking, cooking, baby formula or tea, clean pre-filtered water brings peace of mind to your whole family.
