Filbur FC-6350 Pure n' Clean Cartridge and DE Filter Cleaner

Do not buy this product ever! It does not clean pool filters as advertised. And at $30 a bottle you are better off buying new filters instead.I am still trying to get a refund – their customer service is terrible – they don’t respond to emails and they are not friendly the phone - and keep redirecting you to their voicemail loop I’m hoping Amazon can resolve the refund.

In the end ineffective. With it being weakly sprayed on with a simple trigger sprayer, none of the interior surfaces of the pleats filter media will get coated with product. If you could immerse the entire filter in this solution for a period of time, quite possibly could be beneficial. Filbur really plugs this stuff, but I don't see the end result they profess.Best bet, no plug here, purchase an "Aqua Comb" for about the same price. Still lots of elbow grease involved, but the comb teeth separate the pleats and the micro water jets blast them clean. Kind of a nifty tool. I used this cleaner and The Aqua Comb on 2 of my 4 filters, and just Aqua Comb on 2 and there was no visible difference. Used this product after my test on the other 2 since I bought it and no further cleaning was apparent.

The spray is good for doing a complete job of cleaning all of the nooks and crannies in their pleated filters. It allows for an enzymatic breakdown of a lot of the organic particles and makes their removal much easier.

Spray filter let sit over night in tub of water. Makes filter much easier to clean.

Worked well.

To clean one of my hot tub filters, didn’t do the job

Helps clean the pool filters easier.
