400720A Filter Blaster Swimming Pool Cleanser, 32 fl oz

During Covid lock down and the resultant, impossible, supply shortage, this product was a savior for recycling necessary pool filters. I will buy it again.

We have also just sprayed out our filters to clean them which took a while. Using this filter blaster made the process so much faster and the filters a ton cleaner! I just sprayed each filter all over and let them sit for about 5 minutes, then rinsed with water and the bugs and grime just came right off. My filters were white when I was done! I was amazed.

If you wants to waste your money go ahead and buy it otherwise take your filter cartridge out clean it with the water hose spray it down with Clorox because that is a disinfectant and then spray it down again you'll save yourself the aggravation and need this money because you can't even return it because it's a hazardous chemical..LMFAO.... stupid stupid me I guess Amazon really does only put on the good reviews

I went in skeptical when buying this product. After all, we had previously soaked this filter with another product and we still had this to deal with. What else is there to lose but another few dollars, before calling it quits and shelling out for another filter. So I spray the filter down in case there is large debris there, then I spray the product on there, and it says leave 5 minutes then rinse completely. So I go and start brushing the pool and 10 minutes later (whoops left it an extra 5 minutes) I start rinsing. It took about 20 minutes to completely rinse the product out but, to answer your question, no that is not a new filter! It is the same flipping filter we started with!! I’m a believer and I am absolutely loving this spray!

Works good but is expensive. I like the type that has enzymes in it and you can soak the filter over night. The two work well together. First the enzyme soak and after pressure washing at not to close a range so as to damage the filter spray with the Filter cleaner.

There was a noticeable drop in pool pump water pressure after cleaning. I first cleaned with water as I normally do. I then followed the instructions and cleaned with water again. Be sure to rinse out all the bubbles. There was an improvement over a normal water only cleaning.It looks like I should get about 5 cleanings out of the bottle.

Just cleaned my spa filters for the 1st time using this product. Appeared to clean well.

Did a great job on our filter
