If you want to purify an entire building, the PrO Activ Ox™
Heating, Ventilating and Air Conditioning (HVAC) series is the most efficient way. There are three residential/office models that can treat anything from small apartments , homes or offices up to10,000 square feet of space. Install the Pro Active Ox™ ( HVAC) in your air handler or duct work and you can effectively reach all parts of the home or office. Rather than purchasing several small individual units, you can buy one HVAC unit to take care of the whole house, apartment, office, etc. and have your ducts free from mold and germs as well. This is simpler, as well as more effective and cost efficient and the equipment is then out of site. Whenever your air handler is operating your air is being purified and charged with active oxygen.
Below is a chart of different sized models. Note: conditions may warrant the use of larger or smaller units. Areas of coverage are only meant to be guidelines. Always consider the strength and frequency of the odors and contaminants generated in the air being purified. For example: a home with no pets, no smokers, and few meals cooked would require a smaller unit than a home with pets, a smoker, and all home cooked meals or a persistent musty odor.
