What Is HEPA?
High Efficiency Particulate Air
Sounds important, right? Well it is. For a bag or filter to be true HEPa, it has to be tested and approved.
0.3 Microns or Larger
The Institute of Environmental Sciences and Technology dictates that a HEPA filter must trap 99.7% of particulates 0.3 microns or larger. HEPA filters and bags can remove some bacteria, viruses, mold, dust, pollen, pet dander, and other similar allergens.
If anyone in your home suffers from allergies or if you surround yourself with cute, furry friends, then make sure your vacuum cleaner has a HEPA media filter and/or bag and is a sealed system. Other filtration materials do an OK job of capturing the big stuff, but HEPA media filters trap the microscopic particles, too. Your air will be cleaned as you vacuum so your home will be fresh from the floor to the ceiling.
