Had a particularly bad pollen day out here in NorCal, so decided to give the HEPA filter a try. Here is how the manual describes it:
"When you engage the HEPA option, the fan operates at the highest speed." So gave it a try. And, nothing. The fan was set at 4 and there it remained. Is there some secret code to get the BioWeapon filter to operate?
