Simple and effective bio-mechanical pre-filters improve pump performance, prevents pump damage, and delays flow reduction due to debris and clogs. Expandable units available in single or double Matala® filter media core for superior biological filtration. Universal barbed fittings accept 1-Inch to 1-1/2-Inch tubing or 1-1/2-Inch MPT. The versatile EZ Bio Filter can be used with circulation pumps, filtration pumps, and water fountains.

The EZ Bio 20 has a double filter core with two elements surrounding the suction line; an internal Gray Core combined with a larger Green Outer Core element. The outer Green core element is 8 inch diameter and 7.5-Inches long. The combination of these two filter medias ensures a high level of early pre-filtration.

Replacement core elements are available in Gray size 4-Inch diameter x 7.5-Inch and Green size 8-Inch diameter x 7.5-Inch.

The core element slides over a rigid slotted pipe. This rigid slotted pipe has a 1.5-Inch male thread on one end and a 1.5-Inch female thread on the other end. Additionally, it is possible to connect multiple slotted pipes together to extend the length of the EZ Bio Filter.
