HEPA filtration is over 99.97% effective at removing particulates 0.3 microns
or larger, and air purifiers utilizing this technology have the ability to
eliminate airborne contaminants such as dust, dander, allergens, and molds from
the air you breathe. As such, the Surround Air Intelli-Pro air purifier uses a
true HEPA filter to help you breathe easy, and the IntelliPro-filter is the
replacement filter for the Intelli-Pro. Ensure proper filtration of harmful
pollutants by regularly replacing the filter in your Intelli-Pro every 12 months
with the Surround Air IntelliPro-Filter.
