Better than any other product to clean my filter

Works great. Love not having to buy the disposable ones

This is the best cleaner I’ve found for my permanent filters. I just spray it on and give it a few minutes and rinse. After drying they look brand new

Works well to clean my electrostatic air filters. I followed the instructions and the filters looked very clean after done. I left them outside to dry in the heat, but if it’s winter, I would bring them inside to dry.

It does not work as good as I hoped.
