The short answer is yes. Rooftop air handling units cannot operate efficiently and as designed when air flow is restricted. Restricted air flow prevents proper levels of fresh air exchange and air movement throughout a building or home, which is felt particularly during summer months.
For years MERV 8 and MERV 11 filters were the standard for most buildings and facilities. MERV 13 filters increased in demand fourfold after the SARS-CoV-2 pandemic. These filters are a high-capacity filter that have the ability to capture airborne pathogens like viruses and bacteria. MERV 13 filters become more efficient as the filter media begins to “load” with particles, which helps in the capture of pathogens as small as .3 microns. MERV 13 filters will need to be changed out a little frequently as they will load faster than MERV 8 and MERV 11 filters.
Almost all building RTUs can use our MERV 13 filters and there will be minimal pressure drop. This is due to the fact that our MERV 13 filter media is electrostatically charged, which enables proper air flow but still provides the ability to capture significant amounts of various pathogens through electrostatic attraction.
All of our prevent screens are custom made. We take precise measurements and custom install the screens on any air handling unit. The screens are extremely durable and maintenance is simple: Use a broom or brush to periodically brush off any cottonwood or debris.
We spray with electrostatic sprayers using a Gencie organic solution. This particular disinfectant is a “mechanical” solution, not a chemical solution. Its nano-spikes penetrate cell membranes, rendering them impotent and incapable of replicating. The solution works for a minimum of 14 days and can continue to provide protection for up to 90 days, depending on frequency of contact on a surface and whether or not alcohol- or bleached-based chemicals are applied after our spraying.
