My goto, basic particulate filter.
August 9, 2018
The 2297 is a great basic, general purpose particulate filter and, in my opinion, worth the small price increase over similar, cheaper filters in the 2xxx line, such as the 2091, 2097 or 2291. The efficient air flow design of 22xx filters is a big plus in every day use and the nuisance level organic vapor protection the 2297 provides over the 2291 comes in handy more than one would think.
ProsEfficiently and thoroughly filters a lot of your basic, home particulates.
Filters nuisance levels of organic vapors.
Relatively inexpensive for what it does and how long it lasts.
ConsOnly good for nuisance levels of organic vapors, which 3M literature defines as ?concentrations not exceeding OSHA personal exposure limits or applicable exposure limits, whichever is lower?. Good luck figuring that out! (60xxx filters for higher gas concentrations.)
