The WindTunnel Bagless vacuum is designed with two stages of filtration, providing longer cleaning performance by helping prevent build-up and clogging of the cleaner's HEPA filter. Heavy dirt entering the vacuum is drawn into an empty chamber and kept there by a permanent pre-filter between the two chambers. The pre-filter allows only fine particles to pass into the second chamber, where they are stopped by a HEPA filter. The HEPA filter has a coated surface that helps shed dirt that can clog and restrict airflow. The Hoover WindTunnel Bagless captures 100 percent of dust mites and ragweed pollens.
Homes are often at the heart of allergies.
People spend as much as 90 percent of their time indoors, in homes that are often tightly sealed. Vacuuming more than once a week is recommended for those who suffer from allergies. Old carpets especially can be reservoirs of allergens. In addition to vacuuming the carpet for allergen control, you should regularly vacuum pillows, drapes, bedding and fabric furniture. Also clean along baseboards - dust mites and mold thrive in moisture which often builds along baseboards.
