ASHRAE 62.2-2016 as well as the Florida Building Code require that after July 1, 2017, all new homes be tested for air leaks, and those that are not air leaky must have a mechanical ventilation system installed. Mandatory.

Recent Research Reveals Wonderful Surprises

Improved Cognitive Function (Decision Making)  and Sleep from Reductions in Carbon Dioxide to around 600 ppm and VOCs

Scientists at both Harvard T.H. Chan School of Public Health and at Lawrence Berkeley National Laboratory have recently found that if carbon dioxide levels in a breathing zone were decreased from the old, “ideal” level of 1,100 parts per million to a CO2 level of 600 parts per  million, that cognitive function increased remarkably. Harvard scientists also concluded that CO2 lowered to about 600 ppm would improve sleep.

It is not uncommon that in today’s highly energy efficient homes (without mechanical ventilation), bedroom CO2 levels can approach 3,000 ppm.

Decreased likelihood of Alzeimers and Dementia from Reductions in Inhalation of PM2.5’s Toxic Hitch Hikers. Scientists are increasingly reporting a connection between air pollution and Alzheimer’s. More particularly PM2.5‘s Toxic Heavy Metal Hitch Hikers.

Recently-developed ventilation air intake filters perform at MERV 14-15 levels to remove about 95% of PM2.5 from ventilation air provided into breathing zones. In the recent past, MERV 2-4 filters were considered adequate to filter outdoor fresh air. But No More.

Since we spend a bout 95% of our time indoors, a 95% reduction in PM2.5 exposure in our home’s breathing zone can make a remarkable difference in total PM2.5 exposure.

Scientists have recently revealed that the PM2.5 pathway to enter brain tissue is by contact with the Olfactory Bulb during inhalation. PM2.5 almost always carries toxic hitchhikers like Mercury and other heavy metals which then lodge and accumulate in the brain.

Better Health and Comfort from Reductions in Asthma and Allergy Triggers, Red Tide and Toxic Algae aerosols..

Outdoor air carries respiratory and health risk particles and aerosols such as red tide and, blue-green toxic mold aerosols,  pollen, mold spores, mold particulate, soot, smoke, airborne agricultural particles as well as viruses and smoke

Automobile manufacturers always install first-class, long life filters on the engine’s air intake. WHY? Because they know that a filter will extend the engine’s life.

Do your family’s lungs not deserve the same or even more clean air than your automobile’s engine?
