The Culligan HF-360A/HF-360B 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 Culligan HF-360A or HF-360B is outdoors, near a window, in a garage opening, 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 Culligan HF-360A/HF-360B clear filter housing?
The Culligan HF-360A/HF-360B uses a clear sump so you can see the filter cartridge. That is useful for inspection, but it also means light can reach the water and cartridge when the filter 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.
Compatibility
This cover is designed for the Culligan HF-360A and HF-360B whole house water filtration systems. Check the model number on your filter housing before ordering. Similar-looking Culligan housings may have different dimensions, so model confirmation matters.

FAQ
Will this cover fit the Culligan HF-360A and HF-360B?
Yes. This page is specifically for the Culligan HF-360A and HF-360B whole-house water filter housings. Confirm your model number before ordering.
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.
Can I still change the filter?
Yes. The cover is intended to be removable so the housing can still be accessed for normal filter changes and inspection.
What if my housing is already green?
Clean and service the filter housing first, then block sunlight to help prevent the problem from coming back. For the broader maintenance process, read how to prevent algae in a water filter.
