10 inch and 20 inch filter cartridges are the most common sizes for 3-in-1 pre-filtration sets. Many global distributors are confused about which size fits their market better.
10 inch filters are widely used in standard household water purifiers. They are small in size, low in cost, easy to replace, and perfect for home use and small apartment applications.
20 inch pre-filters are mainly applied in commercial water dispensers, large RO systems and community water purification projects. They have larger filtration area, longer service life and higher water flow.
We supply both 10-inch and 20-inch 3-in-1 pre-filtration sets with OEM support. We can also customize non-standard sizes according to your equipment drawings, helping you match the best filter solution for your local
