Can I use this on my kn furnace filter

No, the K&N Air Filter Cleaner and Degreaser: Power Kleen 99-0621 is only for use on engine air filters. The correct cleaner for the K&N HVAC air filter is the 99-6010.

Do they make this in aerosol form? Trigger will do fine I'm sure, just can't stand the small pump spray bottle.

I've never seen an aerosol form. the one I bought was just like the picture shown, like Windex or other household cleaners.

I have 2 k&n filters and 1 aem dryflow filter. can i use the k&n to clean both, or should i only use the aem brand for the aem filter?

AEM filters are dry flow so you don't spray them with oil like the K&N's. The K&n cleaner is formulated to clean their filters, removing the old oil too. It would probably work fine on AEM,just being a little more harsh but why chance it. It could degrade the element over time. I'd use their stuff so as not to void any warranty. Better yet would be to get all K&N's and be done with it. One brand, one cleaner. Just a thought. Good luck.

Will this work for cleaning a mass air flow sensor?

No!!! A simple search for “mass air flow sensor cleaner “ will yield some products.
