The HPS 500 series units are designed to attach to any forced air ducted heating/cooling system in the partial bypass configuration, the same process we use with our larger HEPA units. When running at the 500 CFM speeds in this configuration, this small unit can provide 24 to 48 air changes per 24 hours in moderate-sized homes and offices.

Size Matters

The HPS units have a very small footprint. They are 13” square and 21” long and weigh less than 30 lbs. As a result, these powerful units can be installed in areas and applications where our larger units will not fit….and installed for less than half the cost of our larger units.

Typical applications and locations when used in the partial bypass configuration are:

  • Town-homes – HVAC unit in closet – minimum space
  • Apartments – HVAC unit in crawl space
  • Condominiums – HVAC unit in a mobile home
  • Homes – HVAC unit in an attic
