Welsh states that to counter health care and lost productivity costs, companies are looking to manufacturers of products that incorporate high-efficiency particulate air (HEPA) filters into their machines.
She notes that vacuums that incorporate a quality HEPA filter effectively rid indoor air of 99.97 percent of contaminants on surfaces down to 0.3 micron in size.
Welsh adds that in choosing the right vacuum, getting the most for your money should be more emphasized than the price tag.
According to Welsh, the vacuum that will increase indoor air quality (IAQ) and productivity the most has a combination of high-powered suction, an exceptional filtration system, superior ergonomics and an extensive warranty on parts, labor and motor.
