How are CTO filters made? To put it simply, it is made by mixing granular activated carbon powder materials and inorganic liquid binders, then pouring them into a special mold, then pressing them with high-pressure compression molding, and drying them after the mold.

In many models of water purifiers, the CTO filter element can deeply absorb different colors, odors, and residual chlorine in the water, and can also filter out fine impurities in the water. It is used for the third stage of work in the water purifier, and also plays a role in protecting the RO membrane, and the service life is generally 3-6 months.
