Just wear an N95 Dust and Pollen mask on your face. Will be easier.I'm interested to see if anyone has looked into a HEPA filter for the cabin air filter. I couldn't find any online anywhere but I was thinking of using the HEPA filter that I sue for my home furnace/AC (which is made by Filtrete), cutting it down to size and putting that in place of the OEM cabin air filter. I know the thickness won't be the same and it won't have a border around it, but I'm curious to try it out and see if it'll work. Has anyone else looked into HEPA options for the cabin air filter? Primariliy of course, even if it's not completely effective, I also dont' want to cause damage to the blower (i.e., wearing out the motor or something due to the much more restrictive air flow). Thanks!!!
