Because windows and doors are generally kept closed in the winter months and people spend more time indoors, indoor air is recycled more during this time of year. In order to keep the air quality in your building healthy all season long, you will need to have the properly maintained air filtration system.
Change Your Air Filter
When outdoor temperatures drop below 40 degrees, it’s your air filter that allows you to keep the air from getting “stuffy” without the need to crack open a window. However, in order to work properly, an air filter needs to be free of dirt and debris. Replace filters according to the schedule recommended by the manufacturer, or use a pressure gauge to determine when the filter has reached its final pressure drop.
Choose Filters with Mechano-Electret Media
With mechano-electret filters, businesses can reap huge benefits. These filters offer a combination of electret and mechanical efficiency and are more powerful at eliminating particles from the air that could cause respiratory problems.
Look into the ASHRAE 52.2 Test Report
The filtration efficiency of HVAC air filters in Richmond are rated by MERV: the Minimum Efficiency Reporting Value. It is measured by the ASHRAE 52.2 Test Standard, which provides the efficiency of the filter over three particle size ranges. It is crucial to inspect the ASHRAE 52.2 Test Standard, especially if occupants in your building have respiratory problems.
