what mask do i buy for solvent based PU varnish?

[alex8542]

Hi,

i have one of those 3M reusable half masks (4000+ series, A1p2) , and i'm looking to buy a catridge for VOC because i'll be doing alot of solvent-based PU varnish. there's quite a few codes floating around, and i'm not too sure which one should i go for.

there the ABEK1, and then there's A1B1E1K1, and then there's the A2p3

which one should i go for? thanks!

The 4000+ series are all in one disposable masks. You would be better off with a 6000 series and AXP3 NR filters
