Phoenix air scrubbers aggressively clean the air of hazardous particles, chemicals, and gases left behind by water, mold, chemical, or fire damage. These heavy-duty air cleaners work by pulling in contaminated air, passing it through multiple air filters that are often HEPA-grade, and exhausting clean air back out into a space or into a separate area through ductwork. Phoenix Guardian air scrubbers can also be ducted to create negative air pressure in a space. This helps limit the spread of contaminants to surrounding areas. These products are proudly made in the USA by Madison, Wisconsin-based Therma-Stor.
