ACS is meeting the latest COVID-19 challenges by providing CDC recommendations.

ACS is in the boxing ring to meet the latest COVID-19 filter recommendations established by the CDC as recommended by ASHRAE, the leading authority setting standards for Heating, Air Conditioning, and Ventilation.

Excerpts from ASHRAE documents are seen as ACS’s ‘boxing gloves’ to the virus. We can help Contractors and Independent Businesses, Schools, and Private and Public gathering places, make any space a safer place. Such points being:

  • Using the right filters: MERV 13 or higher, and when not possible the highest MERV allowable by your system.
  • Using Room Air Cleaners to either increase overall effectiveness and protection against the virus or to substitute when filtration methods above are compromised. HEPA and UV filtration highly recommended.
  • DIY-1. When any space has fresh air available from doors or windows, use it to dilute indoor air, reducing the concentration of airborne pathogens.
  • DIY-2. If none of the above is possible, the minimal strategy involves “mixing up the air” to avoid stagnant air pockets in the room; bring in small fans to gently stir up the air to eliminate stagnation and increase movement to your current system.

While nothing is guaranteed, in preventing transmission of the disease, ACS’s part is to provide the filters and air cleaners and doing everything we can with what we know and what we have. Call us to help with your filtration needs and questions!
