Don't waste your money on the paper type though, they must be the
silicone rubber type and have charcoal filters.  I use a 3M type with
charcoal filters + snap-on HEPA filters (Puchased the HEPA portion
online) and I have yet to find anything that could get through it with
much success.  Great for eliminating virtually any offensive odor as
well as some of the dangerous types, it is truly amazing the dense
smells it removes completely.
