Routine maintenance of portable cleaners and purifiers should be conducted according to manufacturers' directions to assure the best possible efficiency and service life of the unit.

The best thing about our Alpine Purifiers is:
"They use no replacement air filters nor cartridges." 

No more dirty filter cartridges!

Additionally, proper placement of portable units is essential. They should be placed near a specific pollutant source, when it is known, so that they clean the atmosphere at the point where the contamination levels are highest.

The intake and oxygen outlet should not be blocked by walls, furniture or other obstructions.

For maximum effectiveness, all doors and windows of a room being treated by a portable room filters or purifier should be closed.

When using central filtration systems, caution should be taken to ensure that inlets and outlets are not blocked by furniture or other large objects which impair airflow.

Consumers should become as informed as possible about their units, research their options thoroughly, and keep in mind that purifiers are not intended to be the primary solution to health problems related to indoor atmosphere quality and, if consumers choose to use them, they should be used along with appropriate source control, ventilation, and medical treatment.
