The best way to use a HEPA vacuum is to do a once-over with the vacuum, then
wet wash all surfaces with a soapy detergent, rinse with fresh water, and then
use the HEPA vacuum a final time. Use this cleaning method to clean each room
of the house before moving on to a new room.
It is also best to begin HEPA-vacuuming at the back of the house, furthest away
from the entrance/exit door so that dirt is not being tracked into rooms that have
already been cleaned. Work from the top of each room, near the ceiling, to the
floors. Use the special attachments to get hard-to-reach areas.
Most HEPA vacuums can be found online and in local stores such as Target and
Sears.
