BUILDING AIR INTAKE AND EXHAUST DESIGN

UTDOOR air enters a building through its air intake to provide ventilation air to building occupants. Likewise, building ex-haust systems remove air from a building and expel the contaminants to the atmosphere. If the intake or exhaust system is not well de-signed, contaminants from nearby out door sources (e.g., vehicle ex-

Breathe Easy with Fresh Air in the Home

Fresh air is drawn in through an air “intake” vent and distributed to many rooms by a fan and duct system. A fan and set of ducts dedicated solely to ventilation can be used, or an outside air intake can be connected to the main return air duct, allowing the heating and cooling system’s fan and ducts to distribute the fresh air.

Guide to Air Cleaners in the Home

An air cleaner will filter less air if it is set at a lower speed. More air will pass through the filter at higher fan speeds, so typically filtration will be greater at higher fan speeds. Increasing the amount of time an air cleaner runs will also increase air filtration. Portable Air Cleaner. Portable Air Cleaner Sizing for Particle Removal
