Editor's Note: Make sure to read the label of anything you spray on an air filter to ensure it's safe to breath and non toxic.

A better way to trap more dirt is to buy a pleated air filter with a MERV rating of 8 or higher (the MERV rating will be shown on the filter and/or the packaging).

I am no expert but I would think this would impede the air flow. Did you ask the man about that?
