Q: Do you have to use their spray to clean the filter?

I have the 20x20x1 version which is the same but just a different size. They say you should use the cleaner spray, but you don't need to. I don't and find that if I use a hose sprayer and spray from the back side, all of the filter dirt/dust rinses off easily. Just be sure to let it dry before reinstalling. By the way, I love these filters, they are great quality and will last a long time. I have had other permanent filters and they have not been this high quality.

Q: How microns does it block?

It’s my understanding that MERV 11 filters block particles as small as .3 microns

Q: My furnace takes a 4" filter, does that mean I need to stack 4 of these together?

If it's supposed to have a 4", USE A 4! That filter will have a MUCH lower resistance (Static Pressure) across it than a 1". Don't try to redesign. The blower motor is rated for a certain static and THAT is definitely part of the equation. Unless YOU are a HVAC engineer, you are NOT qualified. ( I have 17yrs in HVAC)

Q: Is this still safe to use when you switch over to the heater?

Your K&N filter will work fine with the heater running. I wash mine about every other month and shall again before the heat is turned on. It's not vital but if not done you may get a slight odor of burning dust from the dusty filter. Hope that helps
