Portable air cleaner removes dust and pollen using a true HEPA filter.

Though most of these particles are so small they’re not visible, they can nonetheless be a health hazard, particularly for people who suffer from allergies or bronchial problems. That’s where air cleaners come in.

How Air Cleaners Work

Air cleaners (sometimes called air filters or air purifiers) can help reduce the problem by filtering out the microscopic particles caused by smoking, fireplaces, pets, molds, pollen, and other sources of indoor pollution. A variety of technologies are employed by these devices to clean the air. Some draw room air through finely woven filters that catch particles before returning air to the room. Others, such as electrostatic precipitating air cleaners, use electrical charges to attract particles in the air.
