It's in the BETA stage:
I say 'harmless' because this is so thin and yet will stop lots of crap from getting in.
I started using these as COVID filters under my face gators but quickly found out it needs to be a lot more dense than this...
First, 1 sheet of:
(they are NOT COATED WITH ANYTHING... dry and no oils added)
CUT IN HALF, and trim about 3/4" off one edge...
4 magnets and done
And you can see it should not obstruct air flow but will trap dirt...
check often and use the other half as your next filter
DO NOT USE IF YOU ARE IN DOUBT, but you would have a hard time convincing me it's bad.
First off, this doesn't COVER 100% of air intake so I personally don't see how this will affect the fan in anyway.
( I will be interested to see if it gets dirty enough to say it actually works) like I said BETA stage...
