Set of 2 RO Replacement Filters 11″ | Sediment T33 + Carbon Block
Premium 11″ In-Line Replacement Filter Set for Domestic Reverse Osmosis Systems
Maximize the efficiency and purity of your home’s Reverse Osmosis (RO) water system with our essential Set of 2 In-Line Replacement Filters. Engineered for combined pre-filtration and chemical purification, this kit guarantees crystal-clear, odor-free, and great-tasting water.
This essential replacement kit includes two 1/4″ FPT in-line filters, compatible with most standard residential water purification systems:
- Sediment T33 In-Line Filter (2.5″ x 11″) – The first line of defense.
- 5 Micron Carbon Block Filter (2.5″ x 11″) – For advanced chemical absorption.
Key Features: Sediment Filter T33
The sediment filter acts as the crucial pre-filter for your system, protecting the sensitive RO membrane from premature clogging and damage.
- Action: Effectively removes dirt, sand, rust, silt, and all coarse suspended particles (does not remove chemicals or pollutants).
- Ideal for: Domestic RO systems and under-sink water purifiers.
- Optimal Life: Recommended replacement every 6 months – up to 1 year.
- Installation: Versatile design allows for vertical or horizontal mounting.
Key Features: Carbon Block Filter
This is the heart of chemical purification. The sintered activated carbon block cartridge (5 micron) uses a proprietary blend for superior contaminant absorption.
- Action: Removes up to 99% of chlorine, organic substances, and other chemicals, drastically improving the water’s taste and odor.
- Guaranteed Efficiency: Long service life, filtering up to 9,500 liters of water.
- Technology: The durable, homogeneous carbon block construction ensures a highly resistant structure with exceptional absorption capacity.
