Improve Health, Peace of Mind by Creating Safe Breathing Zones


The quality of air has a direct impact on absenteeism, student achievement and teacher retention.


Together, we can clean the breathing zones in your buildings and defeat the invisible enemies.


Here’s how:


Air handling systems are typically designed for cost and temperature control.


We can add quality air by removing harmful biologicals (respiratory viruses and molds), particulates (smog, dust, pollens, and smoke), and airborne chemicals (volatile chemicals and odors) from your breathing zone.


Optimized air flow (turn over rates), air distribution (avoiding contaminant stagnant-air “dead zones”), and air filtration are key to staying safe and healthy, feeling better, reducing anxiety and achieving more.


You save money in the long run by increasing efficiency, updating equipment, and reducing repair and maintenance time. Learn more here.


Air Flow


Air Changes per Hour (ACH) measures the amount of filtered and conditioned air that a system can produce. Professional organizations recommend 3-6 ACH’s.

Air Distribution


Supply and return air duct placement creates air currents or flows through the room.


Does your system have stagnant dead zones that can trap contaminants?

Filtering


Higher quality filters require higher quality fans to push air through them. Is your system typical and built just for dust removal? Is your neighborhood contaminated with forest-fire smoke, smog, or pollen? If so, do you pre-filter your outside air intake?


Can you add charcoal for odor removal from cooking, smoke, furniture or carpet fumes?

Mechanical Air Filters



Biologicals


Coughing, sneezing, singing, and loud talking produce both droplets and aerosols. Aerosols float in the air like cigarette smoke, quickly filling the room.



Will your HVAC system help you avoid inhaling what someone else might exhale?

Biological Pollutants’ Impact on Indoor Air Quality



Particulates


“Large” particles (PM10) from construction, farm dust, dirt and soot are easily filtered. “Small” particles (PM2.5) from fires or pollution, including smoke and smog are more dangerous since they can cause damage deep in the lungs or blood — and require more sophisticated removal techniques.

Chemicals


Airborne chemicals (Volatile Organic Compounds or VOC’s) are produced by everyday products like paint, carpet and cloth furniture; also cleaning products, cooking, smoking, candles and fires. Regular furnace filters will not trap them. Special filters are required to remove them.

Volatile Organic Compounds’ Impact on Indoor Air Quality



CO2


We breathe out CO2. Too much in the air reduces performance and is an indicator of poor air flow or inadequate fresh air cycling. Too little implies leaky construction or an inefficient HVAC system.

Relative Humidity


Indoor humidity should be 30-50%. Too much allows unhealthy molds and bacteria to flourish. Too little allows respiratory viruses to aerosolize and spread.
