Model number matters. Similar-looking housings can have different dimensions, so match the label before ordering.

Clear is useful for inspection. It also lets light in.

When sunlight reaches the water inside a clear housing, it can contribute to green growth. A fitted opaque cover shades the housing while keeping it accessible for normal service.

If your housing is already green, clean and service it first.A cover helps manage light exposure; it does not replace cleaning, flushing, filter changes, or manufacturer-recommended maintenance.

Before you choose a cover.

Still have a question? Drop us a line below.

Will one cover fit any clear filter housing?

No. These covers are model- or supported-family-specific. Confirm the brand and full model number on your filter before ordering.

What if the housing is already green?

Clean and service the housing first, following the filter manufacturer’s guidance. Then use the cover to help limit future light exposure.

Can I still inspect or service the filter?

Yes. The tool-free cover opens or removes so you can inspect the clear housing and perform normal service.

Can the cover be used outside?

The cover helps shade the clear housing, but it does not provide weather, water, impact, or freeze protection. Install and protect the filter system according to its manufacturer’s instructions and local conditions.
