driamor 16 Pack PF-L Fish Tank Filter Cartridges Compatible with PF20, PF30, PF40 and PF75 Power Filters, Aquarium Large Carbon Filters Cartridge Replacement

There are 16 filters for a fraction of the price of other brands. They work fine and fit fine for any filter system requiring this size filer. Will buy again when I run out.

These work great and are SO much cheaper than buying them from the pet store. The quality may not be quite as good as the expensive pet store brands but having to change them 7 - 10 days earlier is still more cost effective. Additionally I've never had an issue getting them from Amazon while the pet stores frequently are out of stock for the size I need.

Great for my little tank. Great value. Just adding that i reordered more filters. The company was very good about fixing a mistake made. I appreciate there fast correspondence and correction.

A little big for my 3.5 gal. But I bent it and it works

it a great product

Several thing I would like to convey in this short review. 1 - The product is excellent. These exceed the quality of the Top Fin PF-L filters by a great margin. The plastic frame is stronger, the filter material better sticks to the frame better, there is more carbon in the filters and these rinse off easier than the OEM brand name filters. 2 - These are cheaper than OEM original brand name filters. 3 - They will last much longer than the OEM original brand name filters if used even ‘semi-correctly” and do regular maintenance on the filters. By regular maintenance you must rinse these filters once per week by putting them in an empty sink and spraying down all the gunk that builds up on the filter. Sometimes twice per week for this step. Overall I highly recommend these filters over the Top Fin PF-L brand name. They are superior in every way.

Wonderful non-namebrand filters. I honestly think they’re as good or better than the namebrand expensive ones.

No fancy packaging, filters come straight out of the cardboard shipping box. Not really a problem, just surprised. Good fit. I have all natural plants and decor in my tank, so the filters fill up and have to be replaced every 2-3 days. Don't expect them to last 2-3 weeks.

works well with Filtration system and lasts as advertised when used properly. Would purchase again

We have a 20 gallon fish tank, but have 6 small fishes, and they poop out a lot. So we replace the filters every 3-4 weeks.

Parfait pour filtre topfin

There cheaper than the name brand, but they work the same, and you get twice as much.

Excellent
