Product Description
Product Description
This 5 Micron 20" x 4.5" CTO activated carbon water filter replacement cartridge is a heavy-duty solution designed for high-capacity whole house water treatment. Constructed with top-grade coconut shell activated carbon with an iodine value greater than 1100, it provides exceptional filtration performance to reduce PFAS, chlorine, taste, odor, sediment, rust, and organic contaminants. The extra-large 20" x 4.5" size delivers extended filter life, high flow rate, and superior dirt-holding capacity, making it ideal for large households or high water consumption environments. It does not remove healthy minerals or lower TDS, preserving the natural quality of water while ensuring safety. This cartridge fits standard 20" x 4.5" big blue filter housings and offers easy installation for whole house, commercial, and industrial pre-filtration systems.

Advantages
-
High-Grade Carbon with Iodine Value >1100 Adopts
100% high-density coconut shell activated carbon with iodine value above 1100, delivering stronger adsorption capacity for chlorine, odor, organic pollutants, and tiny impurities. The high iodine value ensures deeper purification and more consistent filtration performance than standard carbon filters.
-
Authoritative Safety & Material Certification Adopts food-grade materials, certified to NSF/ANSI 42 standard; meets EU EC 1935/2004, ISO9001 quality system, RoHS, BPA-free, lead-free, and other safety requirements. Each filter undergoes 34 production processes, 400PSI pressure test, 10,000 water hammer tests, and 6 independent quality inspections to ensure safety and stability.
-
Efficient & Precise Filtration Performance With filtration precision of 0.5/1/5 micron available, it effectively removes up to 99% of chlorine, odor, sediment, rust, sand, silt, iron, and suspended particles; improves water clarity and taste without carbon leakage, black water, or excess dust. The high iodine value enhances the removal of organic compounds for cleaner, fresher water.
-
High Capacity & Long Service Life Filtration capacity ranges from 13,000 to 50,000 gallons (depending on water quality). Recommended replacement cycle is 3–6 months, with high dirt-holding capacity and slow clogging, balancing long service life and high filtration efficiency.
-
Strong Universal Compatibility
Fully fits standard 10×2.5 inch, 10×4.5 inch, and 20-inch filter housings; compatible with most whole-house systems, under-sink filters, RO systems, pre-filters, refrigerators, ice makers, coffee machines, and dishwashers. No brand restriction, fully universal replacement.
-
Stable Flow & Eco-Friendly Design Provides steady water flow without wastewater discharge; no surfactants, binders, or chemical additives; does not reduce TDS or remove healthy minerals. Low operating resistance, low clogging risk, cost-effective and environmentally friendly for daily household use.
Removal of pesticides, residual chlorine and other organic substances, iron and manganese and other heavy metals, bacteria, odor, color and filtration of fine impurities.
Q&A
Q: Is this CTO filter suitable for well water?
A: This filter is designed for municipal tap water; it cannot effectively treat heavy metals, bacteria, or large amounts of sediment in well water. For well water, please use a special well-water filter system.
Q: How long should I flush a new filter before first use?
A: It is recommended to flush the new filter for 5–10 minutes before use to remove residual carbon powder and ensure clean, clear water output.
Q: When is the best time to replace the filter cartridge?
A: Normally replace every 3–6 months, depending on local water quality and daily water consumption. If water flow drops significantly, taste worsens, or color changes, replace immediately.
Q: Do I need professional help to install this filter?
A: No installation expertise is required. Just turn off the water valve, remove the old cartridge, insert the new one, and restart water supply. Most users can finish replacement in 2–3 minutes.
Q: Will this CTO filter reduce TDS or remove healthy minerals?
A: No. This CTO filter only removes chlorine, odor, sediment, and organic impurities; it does not lower TDS and retains beneficial minerals in water, making it different from RO filters.
