Chryseos Pool Filter 4-Pack

Technical details

The four-filter pack is sized for replacement jobs where matching the cartridge dimensions matters as much as matching a part number. Each filter is listed at 26 1/4 inches long and 7 inches in outer diameter, with 3-inch openings at both ends. The stated material area is 4 x 105 sq. ft. That gives you specific measurements to compare with the filters already in your pool system before ordering.

The product is listed as compatible with C-7471, Clean and Clear Plus 420, CCP420, R173576, 178584, PCC105-PAK4, FC-1977, 570-0425, 160301, Waterway Crystal Water 425, AK-60431, 570-0425-07, SD-00163, Aladdin 20503, and FC-6470. The listed names and part numbers are used to describe compatibility, Chryseos is an independent brand. A solid pick if your current filter matches one of these references and the stated dimensions.

What it works with

This set is intended for pool filter systems that use one of the compatible filter references above. The model list is useful when the old cartridge label is still readable, but it should not replace a physical size check if you are uncertain. For example, before replacing the filters during a routine pool cleanup, compare an old one’s length, outside diameter, and openings with the listed measurements. A similar-looking part number alone may not settle a fit question.

Usage tips

The listing describes the filters as easy to install and clean with regular maintenance, but it does not provide a cleaning method or schedule. Follow the instructions for your pool system when removing, cleaning, or replacing filters. Keeping the old cartridge nearby while you check the new set can help reveal a size mismatch before installation, rather than after the housing is open and the pool is waiting for service.

This four-pack makes sense when you need multiple matching replacements at once. If you only need one filter, buying a set of four may leave you with extras. And if your system uses a different size or an unlisted model, these compatibility details do not establish that the filters will fit.

Practical doubts

How many filters are included? The product name identifies a four-pack, and the listed material area is 4 x 105 sq. ft.

What are the filter dimensions? The listed length is 26 1/4 inches, the outer diameter is 7 inches, and both openings are 3 inches.

What if I do not know my filter model? Compare the dimensions with your existing filter and check its part number if available. If neither gives you a clear match, this listing does not provide enough information to confirm compatibility.

Buying verdict

Choose this Chryseos set when you need four replacement filters and your current cartridge matches a listed reference and the stated dimensions. It offers a clear compatibility list and measurements for narrowing down the fit. Not the best choice if you cannot verify the size, need a different number of filters, or want a replacement for a model that is not listed. In those cases, a single-filter option or a cartridge with confirmed matching dimensions is a safer direction.
