HaywardW3C500 StarClear Cartridge Pool Filter, 50 Sq. Ft., Gray

So far it's okay filter, you only have 1 option for inlet from pump, which is opposite the outlet, most other pumps give 2 for pump inlet, fittings for pump inlet and outlet should be o ring type fittings for DIY, AS FAR as automatic air discharge you still have to open the purge valve and close it, not automatic at all, a very good filter comes with the pump, the cover gasket is excellent (use oring lube to make it last), put a large cover over the filter retatiner to pro tect from the sun, you're all set, also you can get filters easily some you can not!

Perfect replacement for same model over 20 years old.

Had to replace my old unit. This one is very different in color and in shape, but everything else is the same and lines up perfectly. Very little work to put this unit in. I flipped the switch after the PVC glue cured and it worked beautifully. Seller worked with me when I had an issue that was my fault. I will make shade for this unit since UV rays break down polymers. Hope this filter lasts as long as my old one.

smaller than it looks in the picture, so it has to run longer time and clean the filter more frequently

I first tried to save some money & bought an off brand for half the price, but when vacuuming the pool a lot of stuff blew right back into the pool due to cartridge inside fit to loose to the filter housing.Returned that one and purchased the Haywrd filter, no stuff got past filter and back into pool.With In a day my pool was clear again.Well worth the extra expense.

Works grate nice size, good quility. Easy install

The media could not be loaded. Works great as designed. I vacuum my pool twice a week and it has never clogged up on me. Then again I do wash the filter every other week. Not sure if thats an overkill but I like to keep in clean. I do want to mention that it is made out of plastic so be careful when bolted it down, you can damage it. Other then that I think its a great design and all the pool companies out here must think the same because they all seem to use this filter or the next model up. I have it paired with a Hayward 1.5 horse power pump and together they work great.

Replaced my sand filter with this cartridge filter thinking it would catch fine debris like my dead mustard algea on the bottom of my pool that i can not get rid of. I even purchased a second cartridge so i can swap out as soon as im done vacuuming. Apparently its just getting past the filter and blowing right back into the pool. Down to using a skimmer sock, but if this doesnt work, Im done with having a pool, and I'm tearing it down!!! Never again will i purchase a pool.
