Lux Guardian Ultra canister vacuum cleaner by Aerus - The Healthy Home Experts.

How the Lux Guardian Ultra Fights Indoor Air Pollution
A five-stage process and a patent-pending filter design take cleaning to a higher power:
- Stage 1 - Ultra filtration Home Solutions Filter Bag provides four times better filtration than previous 4-ply design filter bags.
- Stage 2 - High-porosity, activated carbon layer removes odor from the air.
- Stage 3 - The true HEPA filter traps and retains 99.97% of pollutants as small as 0.3 micron.
- Stage 4 - Ionization layer introduces negative ions to cleanse the air, a process that occurs in nature. Most importantly, Lux Guardian Ultra produces no ozone during filtration.
