Indoor Air Quality
Pursuant to the ASHRAE guidelines, we have been presenting several options to our commercial accounts. Ultimately, the goal is to make your staff, customers and visitors feel as safe as possible. While each application is different, there are solutions that can be implemented at your location that will demonstrate your clear commitment to meeting that goal.
FILTERS - To catch the virus
Filters are rated on a MERV scale. We currently install MERV8 filters. The recommendation is to upgrade to MERV13, where possible. While viruses are smaller than the .3 microns these filters capture, contaminants tend to bind to dust and aerosols, making them more likely to be caught by the filters. The challenge is that not all systems are designed to handle the increased resistance from these upgraded filters. We would need to evaluate your equipment to determine if a straight replacement can be done or if some modifications need to be made to your system(s). It should be noted that these filters are currently in short supply, since they're made from the same material as N95 masks.
AIR TREATMENT - To kill the virus
UV light has been used to sterilize water, food, equipment, and the air since the early 50’s. Contaminants that are exposed to enough direct UVC light are destroyed. However, it can’t be used in an occupied area so one manufacturer is using UV bulbs, with a catalyst, to produce Ionized Hydro Peroxide Molecules that flood the space. These molecules neutralize pathogens, mold spores, VOC’s etc. that haven’t been exposed to enough UV light. Other particulates, as well as the neutralized pathogens, are more likely to ‘clump’ together because of the positive/negative ions created in the process. This makes existing filters more efficient. RGF recently tested their REME HALO product against COVID 19 and found it to be 99.9% effective in neutralizing the virus. They’ve run successful tests against many of the Novel viruses, Rhinoviruses, molds, pollens etc., so even after this pandemic, your facility can continue to benefit from installing the systems.
A different ionization approach is done without UV bulbs - Needlepoint/Bipolar Ionization. This technology uses negative ions to disrupt the cell wall of contaminants, which neutralizes them. One manufacturer, Iwave, has run tests against COVID 19, with an over 99% success rate. They've also shown that their systems effectively make a MERV 8 filter act like a MERV 13.
FRESH AIR - To flush the virus
Since we know indoor spaces are more contaminated than outdoor spaces, it stands to reason that we want to bring in as much outdoor air as possible. Modern systems are designed to have some minimum level of outside air, which we will verify and/or add to the system(s) with new dampers or Energy Recovery Ventilators (ERV). ASHRAE has recommended flushing buildings pre- and post- occupancy. We accomplish this by modifying the controls for your economizers, automating the outdoor intake dampers or altering the existing control system. If outdoor air is above 38 degrees we will run the system with maximum outside air for 2 or 3 hours overnight. This gives the space enough time to recover from more extreme temperatures.
PORTABLE - For flexibility
There are a number of manufacturers that have portable, 'all-in-one' units. for individual rooms. We've provided several different types that customers have used to facilitate in-person meetings.
