As a gift, I received a circular Honeywell air purifier, model 50100.
It has a

trying to
make sense of this logic. When you vacuum the HEPA filter, you're
pulling the
fine particles away from the filter and spewing it everywhere via the
vacuum
cleaner. I'm sure there's some logic behind it, but it just isn't all
that
obvious right now. Insights are appreciated.
REAL HEPA filters are made from layered spun glass and they should not
be vacuumed. They need to be replaced when full. If you have to wash the
filter your taking the chance of mold or bacteria growth. Don't trust
Honeywell's off the wall claims! Also Honeywell HEPA air cleaners have
a VERY low air exchange rate per hour even in a small bedroom sized area.

I never like HEPA filters, but they work well in disk drives. For volume
efficiency, use an electrostatic filter. I have used several whole house
system filters on the furnace/air, and the best are the 3M but also have
lower thermal efficiency. You can also wash many of the fiber
electrostatic air filters, but the cardboard makes it difficult. If they
were made it out of plastic, you could easily clean them.
