Studies show that 1 out of 4 U.S. homes contain high levels of dust mite allergens, according to a national survey conducted by the National Institute of Environmental Health Sciences.    Ventilation, air conditioning units and appliances should be responsible for maintaining comfort.   When in fact, they could be recirculating irritating particulates.  Current design practices are to construct airtight buildings that provide greater energy efficiency.  By sealing up a building, you’re in fact keeping out the fresh air needed to displace stale indoor air.  Continuously recirculated old air contributes to unhealthy indoor environments caused by a build-up of particulates, germs and potentially dangerous chemical pollutants.  Fifty percent of all illnesses are either caused by, or aggravated by polluted indoor air, according to the American College of Allergists.

An Integrated Approach to Filtering Indoor Air

Permatron offers a line of cut-to-fit vent air filters.    Designed to compliment, not to replace furnace filters, vent filters work to capture pollen, pet hair and dander, smoke and other potentially harmful particles before they can enter your ventilation ducts.

Eliminate Dirt Build Up In Ventilation Ducts

Many homeowners may notice “black soot” on the wall area surrounding the air intake vents.  Dust and debris constantly enters the HVAC system, and can cause build up throughout the ducts and on system components.  Dirty systems also experience higher static pressure drops across system components and can “overheat” motors.   The layout and construction of the forced-air duct system is different in each house and will result in different airflow patterns and particulate concentrations.   Particle concentrations vary widely throughout a typical day, with higher levels of particulates in the air during periods of activity in the home.   In homes with ducts built into the floors, high amounts of dirt fall into the ventilation system, especially in high foot traffic areas.  A good way to combat that would be to install filtration media in the intake and return vents.
