WATER PURIFIER FILTER ELEMENT
water filter Cartridge is the core component of any water filtration system, responsible for removing contaminants such as sediment, chlorine, heavy metals, bacteria, and dissolved impurities. Different types of filter elements target specific pollutants, ensuring safe and clean drinking water.
Based on Filtration Technology
PP (Polypropylene) - Disposable sediment filters.
Carbon (GAC/CTO/Block) - Improves taste & removes chemicals.
Stainless Steel Mesh - Reusable pre-filter for large particles.
Ceramic - Long-lasting, cleanable bacterial filter.
TFC (Thin-Film Composite) RO Membrane - High-rejection desalination.








Number | Name | Efficacy | Replacement cycle |
1 | PP cotton filter element | Filter large particles such as silt, rust, etc | 3-6 months |
2 | UFD granular activated carbon | Adsorption of residual chlorine, odor, and some organic matter | 6-9 months |
3 | CTO compressed activated carbon | Filter out odors, residual chlorine, and impurities | 6-9 months |
4 | RO reverse osmosis membrane | Filter heavy metals such as viruses, bacteria, and other organic compounds | 18-36 months |
5 | Post activated carbon | Inhibiting bacterial growth and improving taste | 9-12 months |
