Pentek Bag Filter, 155384, BP-420-1 Polypropylene 1 Micron, 4.5" x 20"

Worked great to remove dead mustard algae / pollen / dust (not sure what I was dealing with) from above ground pool that cartridge filter was missing. Zip tied it onto a return hose and ran the pump for a few hours. Pool is finally back to normal :).

I have a 18' Intex swimming pool that had a major attack of algae at the end of last season. I was thinking I was going to have to empty it. I then found these mentioned on a YouTube video, and decided to give it a try. Man, these guys are the real deal. The amount of junk it catches that the filter misses is phenomenal. They can be used by simply throwing them in the wash. I am thinking I will continue to use these throughout this season as it works better than the paper filters, and they are reusable. Inexpensive too. Thank you whoever makes these. If you have a dirty swimming pool, get these.

Great you have this item. I was lucky you had it. Going to use it to filter the sump pump water so my lawn will not be full of 24 weeds.

A minor inconvenience over the past couple decades with sediment and sand plugging up faucet screens and making their presence in the toilet tanks and setting a routine every two or three months of cleaning all the fixtures. With this bag filter setup there is little, if any perceptible pressure or flow loss and no sediment or sand in our water. Our plumber recommended we check it in six months to see how much is collected, and if the pressure gauge on the filter assembly is low, change the filter. The filter change process is very simple and relatively inexpensive compared to the extensive time for plumbing cleanings every couple of months as we did before the filter addition.
