Why is my house other dusty when i vacuum regularly and the window are almost other shut? ...
Probably your air return. Dust your nouns vents, they're probably simply circulating dust!!
dust is mostly shed skin cell. we shed our skin about every 28 days (just not adjectives at once).
i learned that surrounded by bio when someone said "i have dust within my eye" and my teacher told us what it really is. in a minute i always reckon "ew, i have skin surrounded by my eye" lol
Answers: Houses aren't air tight (if they be, we'd all asphixiate.) So, likelihood are it's coming in through gap in your windows/doors, or the heating/ventilation system.
Tape a white quality newspaper towel over one of your registers (air vents) in one of the dustier rooms and see if it get dirty on the side facing the vent. This would imply the dust is coming from your aeration system.
You could then hold your air ducts cleaned, or even see if your airing device (furnace, etc) is in a dusty nouns.
Dust and dirt can also come from shoes and clothing. Do you have kids who regualarly play outside? If they come home next to muddy shoes on wet days, next they're probably bringing in dust on dry days.
Do you hold any exercise equipment (especially treadmills)? These abrade the soles of your shoes and cause dust. Do you live beside a lot of individuals? Dust can be dead skin.
Also, vacuums necessitate to exhaust some air to work. Maybe you obligation a new filter for the vacuum.
