A twist-in CTO water filter (carbon block filter) is typically the second or third stage filter in a reverse osmosis system. Aqua-Win coconut activated carbon filters can improve the taste of water and remove chlorine to protect the RO membrane.

Carbon filters remove contaminants by attracting and trapping them on their surface. They can also act as catalysts, which means they can change the chemical composition of certain substances. For example, carbon filters can remove chlorine, pesticides, chloroform, and VOCs from water.

Their efficient filtration capabilities ensure clean water and improved air quality.

For other filters, please refer to TWIST-IN CARTRIDGE.
