Question on Cartridge Filters

Postby JimW » Thu 21 Mar, 2024 09:20

I have a Hayward 4 barrel filter housing (so I thought) I just bought the house and know very little about pools and up keep. YouTube is my friend..... Not knowing the history of the filters that are currently in use I figured it would be best to just replace with new. Previous owner did not take very good care of things. When I opened up the filter housing to see what was inside I found out I had 8 filters not 4. I have a plastic divider or spacer that puts 2 together to make 1 large filter. My question is this normal ? it does look like these will be easier to clean then the longer ones.

Can be normal, with cartridge filters what is the absolute size of particles they trap? Most are just strainers and therefore a waste of money. Needs to be 4 micron or better ideally. Sand is only 20 microns but Dryden Aqua's AFM ng is 1 micron now we are talking filtration and using the electricity wisely.
I may not give you the answer you want to hear, but I will give an honest opinion of your situation as you decribe it.
