Indoor AirPlus and Viruses, Bacteria and Mold

The Centers for Disease Control and Prevention (CDC) recommends increasing building ventilation rates to reduce the concentration of any viruses present. Indoor AirPlus homes include whole building mechanical ventilation systems that allow the homeowner to control ventilation rates and dilute contaminants in the air.

Viruses and bacteria can be present in airborne particles released by the swirl of flushing water in the toilet. Indoor AirPlus homes provide local, mechanical venting directly to the outdoors in each bathroom which will help exhaust potentially contaminated air close to the source.

High levels of filtration can help remove particles from the indoor environment, including particles that may contain viruses. The Indoor AirPlus Construction Specifications require a MERV 8 filter to be installed in central forced-air HVAC systems, but EPA highly recommends a MERV 13 filter for added protection.¹

It is important to keep the indoor air dry enough to help prevent the growth of mold. If indoor air is too humid, moisture can condense on surfaces and enhance the growth of mold. Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints. ²  The moisture in Indoor AirPlus homes is carefully controlled, both mechanically and by the tightness of the home, to reduce mold growth and maintain a healthier level of humidity.

Pests can be a vector for disease and bring undesirable pathogens into homes. Indoor AirPlus homes minimize pathways available for pests to enter the home by sealing penetrations and blocking other building openings with corrosion-proof screens.
