Now is the time to design and install new and retrofit systems that will provide safer indoor air quality.

Data suggests our outside air is NOT clean enough to avoid potential negative health consequences. And it will not become clean enough in the foreseeable future. Our current, intermittently filtered, recirculated, indoor air systems are not capable of filtering the very small particles that pose the greatest potential health risk. And they do nothing to keep outside air particles out of our homes or schools.

These include infiltration of nanometer sized outside air particles, off gassing of furnishings or residual toxic chemicals from the recent wildfires, carbon dioxide from respiration, cooking, or the other common sources of reduced indoor air quality.

Everyone can benefit from a change in approach to HVAC that will minimize the potential negative health effects of current and future events such as fires or wind-blown contaminants.
