I moved into a very dusty old house. It was quite obvious where all the
excess dust was coming from. Ceiling to wall joints not taped and joined,
covered with loose fitting crown molding. Floor to wall joints with large
gaps and baseboards 1/2 inch above the floors. Drafty windows, dirty ductwork,
Because I work out of my home, creating a new office was my first priority.
All new insulation, wiring, drywall, all seams taped and jointed, new flooring,
etc. Airtight except for the vents which also have their own independent
filters. Virtually no dust at all in this room. Even between the monthly
cleanings of the office, you find very little dust on anything.
I renovated the master bedroom second, in like manner. Sealing everything
to the hilt. Naturally, since it is a bedroom, we are handling clothing
and linens in that room everyday. Yet it still gets very dusty in only a
day or two.
Knowing the rest of the house is still very dusty, and there will be continuous
renovations going on. I installed a small fan with HEPA filter in the ductwork
to maintain a small positive pressure in this room. The reason was to keep
dust from coming in under the only door to the bedroom.
This filter picks up very little dust, so it's not coming in from the ductwork.
Can this much dust really be coming from clothing and linens?
I get more dust in this room, settling on furniture in 3 short days, than
I get in my office in a full two months, even if I skip cleaning my office
The rooms are basically identical, the office being built as if it was a
second master bedroom only smaller.
The amount of dust is just mind boggling and I have no idea where it is coming
