Is there rule of thumb as to how long set of filters should last? What should I be looking for other than the obvious wear and tear to determine if replacement is necessary? Is it best to replace both filters of a S8M150 at the same time? Current filters are original install, approaching 10 years of year round service.

Good morning Em, There is no really set time for an element. The best way to tell if you need one is. You can look at it .If the bands around it are broken that is one sign. If  it looks collapsed or soggy there's another. You can also pressure test it. by running the filter with the element out to see what your operating  pressure should be. Then putting the element back in and seeing how much it has raised. If it raises 5psi or more it can be replaced.

My current sta-rite filters are catalog numbers 25201-0222 and 25022-0222. What is the new part number for direct replacements for these two cartridge filters.

A  Answered on 5/22/2018 by InyoPools Product Specialist Lennox H.

Hi, Greg. I was unable to cross reference those number to a replacement. If you can provide the filter model, I can use that to locate the replacement cartridges.

What size of particle will this filter allow to pass? 1 micron? 2 micron? 5 micron? Thank you!

A  Answered on 11/27/2018 by InyoPools Product Specialist Steve M.

This filter doesn't have a specific micron rating. However, a normal cartridge filter will filter out between 5 and 20 microns.

My OEM filter PNs are 25022-0228S and 25022-0225S and the filter model is S8M600 Will this fit?

A  Answered on 4/28/2019 by InyoPools Product Specialist Lennox H.

Hi, Eric. It appears that the parts for your original model are no longer available. You can use the S8M150 cartridges, however, you may have to replace the Elbow and Bulkhead Assembly - 25021-0100
