What are the benefits of ambient air filtration versus exhausting contaminated air to the outside?

Exhausting contaminated air to the outside carries several risks and costs. Fortunately, those problems are solved by using air filtration equipment. Below are some of the reasons to avoid exhausting your air:

  • Energy Costs: When you exhaust heated or cooled indoor air to the outside, you are blowing money through the roof. Fresh air will need to be re-heated or cooled to indoor temperatures again. This is similar to the effect of running your heater or air conditioner with all of the windows open.
  • Environmental Regulations: The Environmental Protection Agency (EPA) maintains air quality regulations that could be broken if you release too many contaminants into the air in too short a time.
  • Worker Health: Dirty air that travels across a facility on its way to being exhausted comes into contact with many workers along its path. If this air contains harmful substances, workers will be exposed, threatening their health and your facility’s compliance with permissible exposure limits.
  • Community Health: The exhaust could negatively impact the community. In a worst-case scenario, unhealthy air could cause health problems in the community. But even bad smells could cause reputational damage.
  • Water Pollution: Contaminants that gather on the rooftop could get washed away and enter the water system, damaging the environment.

Implementing an ambient capture air filtration system solves these problems by filtering the dirty air and returning it to the facility. Here are some of the obvious benefits:

  • Major energy savings. Because you avoid the need to bring fresh air into the facility, you avoid the need to heat or cool that air. In cold and hot seasons, this leads to major energy savings.
  • Containment. Nothing escapes to the outside where it could cause environmental or community health problems.
  • Improved worker health. Workers are exposed to fewer contaminants. This protects their health and productivity, as well as keeping you compliant with permissible exposure limit regulations.
