Positive Pressure Filtering
Virtually all buildings exchange air with the outside environment through cracks, windows, and permeable surfaces. This allows many contaminants (chemical, biological, etc...) that are outside of your home to come inside. If there are any airborne biological or chemical threats outside then you are constantly at risk of exposure. Positive pressure filtering protects you from this.
How Positive Pressure Filtering Works
Positive pressure filtering pushes air through a filtration system into your home ensuring that the pressure in your house is always slightly higher than the pressure outside. This causing the air exchange to always flow from your home to the outside, with the exception of the air coming in from the filtration system, making it nearly impossible for contaminants to enter your home through regular exchange.
