Purifan Systems offer you different filter options to tackle your specific needs.
PurusAire I Filter - Ideal for dealing with Allergy, Asthma or other respiratory issues.
This filter consists of multiple layers including:
- A polyester pre-filter that captures bigger particles like dust, hair and bugs
- An activated carbon filter to filter out odors
- A HEPA filter, which filters out all micro-particles down to point 3 microns, which are the hardest of all to capture.
- This is all followed by another layer of charcoal.
PurusAire II Filter - Perfect for solving smoke issues. This is our strongest filter,
which consists of:
- A polyester pre-filter that captures bigger particles like dust, hair and bugs
- An activated carbon filter that filters out many gases and odors associated with smoke

The HEPA material (High Efficency Particulate Arresting) used in our PA-I filters was developed by the Atomic Energy Commission to remove radioactive particles from the air.
