Water Filter Housings Frequently Asked Questions

What Are Water Filter Housings?

A water filter housing is a vessel which holds water filter cartridges, filter bags, or filter media.

Housings are design to accept incoming water and direct it through whatever filter it holds.

Filter Housings come in a wide range of designs and sizes. While most are made from plastic, there are also stainless steel models available for industrial and maritime applications.

What Size Are Under Sink Filter Housings?

Most under sink uinits are 10″ x 2.5″ housings. However, there is a lot of variance in terms of port sizes, filter head, and thread types.

Most under sink units use double open ended filter housings. However, some older units might have filters with a threaded end or a single open end. That’s why it’s always advisable to examine the filter itself before buying a new housing.

What Are Cartridge Filter Housings?

Cartridge filter housings have sumps which are screw onto a filter head. The sump contains a cartridge filter, while the head has controls water flow. The water filter system’s inlet and outlet are usually on the head.

In most cartridge housings, the water will enter one side of the head before flowing into the sump. Water flows through the cartridge and back up to the outlet on the filter head.
