  • After shutting the pump down, closing the valves, and taking the filter out, simply use a hose and gently wash the pleats. Be mindful, however, as improper cleaning may lead to damage of the fabric or filter, shortening its lifespan.

  • The greater the pleats of your pool cartridge filter, the bigger the surface area, and thus, it will last longer since there is more space to trap debris.

These fit perfectly and are much better at filtering smaller particles out of the pool than the stock filter grids. Would buy these again and again without question.

You have to have this if you keep cleaning the pool & the pollen just blows out of your cleaner.Traps the finer pollen/sand as well as everything else.Cleans out fine with garden hose & sprayer.

I though theses filters would pick up the mustard algae at the bottom of my pool but they didn’t pick up much at all. I ran the dolphin twice between cleanings. The filters were a little dirty but it just didn’t make much of a difference in my pool.

Removes fine particles better than the standard filters. I’ve run back-to-back cycles comparing these and they are 3-4 times better.

Got these to replace the OEM filters in my Nautilus CC Plus. They fit just like the originals and seem to perform equally as well but at a much better price point. I've been running them for about 4 months now at the height of swimming season and after several cycles they are holding up well and performing about the same as new. I expect they'll last through this season and into the next.

Perfect fit for the filters in our Dolphin Nautilus CC Plus. The filters can be easily cleaned, although they get stained with algae over time.Suction power in the unit does not seem to be affected by using these filters instead of the coarser, standard ones.

I don’t know why other reviewers say they are tight or don’t fit well, mine were perfect. Locked into place just like the originals. Exactly like OEM at half the price, how can you complain? Really good product.

Works well with our Dolphin Nautilus CC Plus. I read the prior reviews about a tight fit, but I found no problems. It should be a little snug or it would leak debris. We have had them for a year now and they work just as well as the first time we used them. We have red, sandy dirt particles that blow into the pool and only fine filters like these will remove the dirt. Advice for insertion: The outside edge of the filter has plastic "x" structural support - the supports must be on the outside for a proper fit. Note the two tabs on the bottom edge of the filters. These tabs will match with two receptacles on the bottom of the Dolphin filter frame. Push these two tabs into bottom of the Dolphin frame and the top will line up. After both filters have been inserted into the frame, there is a mechanism at the top of the frame that rotates and locks the filters in place with an audible snap. I wash the filters with a jet of water from a hose just after removal from the pool. If you allow the dirty filters to completely dry, it is more difficult to remove the dirt.
