The GE GXWH20T water filter cover from Part For That is made for homeowners who want a fitted way to shade a clear whole-house filter housing. If your GE GXWH20T is outdoors, near a window, or anywhere sunlight can reach the clear canister, covering the housing helps block the light that can contribute to green or dirty algae growth.
Why cover a GE GXWH20T clear filter housing?
The GE GXWH20T uses a clear filter housing so you can inspect the cartridge. That visibility is useful, but it also means light can reach the water and cartridge when the housing is installed in a bright location. Sunlight exposure is one of the common reasons a clear water filter housing turns green.
- Blocks sunlight from reaching the clear housing.
- Helps reduce algae growth caused by light exposure.
- Keeps the housing accessible for filter changes.
- Looks cleaner than foil, towels, paint, or improvised covers.

Does this stop algae in a water filter housing?
The cover blocks sunlight from reaching the clear housing, which helps address one of the main causes of algae growth in exposed clear filter housings. It is part of proper filter maintenance, not a replacement for changing cartridges on schedule.
