How Important is Vacuuming?
Vacuum frequently and effectively. When carpets cannot be removed, use a HEPA or ULPA rated vacuum cleaner to prevent dust from spewing back into the air as you vacuum. Most vacuum cleaners are not efficient at containing dust in the bags, and can result in dirtier air as you clean. Micro lined vacuum bags should be used in all vacuums not rated as HEPA or ULPA Avoid using heavy curtains and draperies.
