About This
- Premium Quality Material: Our CTO(Chlorine, Taste, and Odor) filter is made of pure coconut shell activated carbon block, wrapped in two food-grade non-woven fabric layers to prevent carbon particles from entering the water. Tested by independent third-party to meet NSF Standards for material safety.
- High-efficiency Filtration: The 5-micron CTO filter can absorb up to 98% of residual chlorine, remove taste and odor, prevent water discoloration, and significantly improve water quality. Use this whole house CTO filter and PP sediment filter in your home water system to protect your water softener and appliances.
- Long Service Life: The 5 micron rating of the CTO water filter makes a balance of sufficient filter efficiency and high water flux. To achieve optimum performance, we recommend replacing it every 9-12 months or depending on your water quality.
- Universal Size: 4.5”x20” whole house filter for any standard 20-inch heavy duty whole house filter housings.
- Satisfaction: Our one goal is to improve the water quality of our customer’s homes. If you are not completely satisfied with your Airthereal purchase, we will be happy to make things right for you.
