“I was surprised to see that Consumer Reports did not consider the 381 effective at filtering emissions. However CR liked the model 321 on emissions. What type of filter do the 321 and 381 have?”

Can't speak for the 321 but the 381 has three filters a foam one, a felt one, and what I believe may be a charcoal filter. I have washed the foam and felt filters, but have not done anything with the other one.
Sorry, there was a problem. Please try again later.A foam filter and a felt filter. Both easily removed and washable.
