Ideally, your office or school will make multiple COVID indoor air management improvements including HVAC ventilation, filtration, purification, & disinfection.
An upgraded MERV-13 filter removes at least 85% of particles greater than 1 micron as they pass through the room’s HVAC system, which recirculates indoor air.
Minimum Efficiency Reporting Value (MERV)
MERV is a rating based on the percentage of particles a filter can collect in a single pass. Because of physics, smaller and larger particles are easier to trap and most filters are least effective at 0.3 microns. MERV-13 is recommended because it blocks most particles in the 0.5 to 1 micron size. Many HVAC systems are built to run MERV-8 filters. As a result, allowing air to flow faster with less resistance but trapping only 40% of particles in the 1 micron size.
Contact nearby RAM Air for a certified HEPA air purifier or cleaner that is appropriately sized for the room. Most importantly, a HEPA filter removes more than 99% of airborne particles that pass through it, including COVID.
Scientists conclude portable air purifiers with HEPA filtration remove virus particles that cause COVID 19
Portable HEPA (high efficiency particulate air) rated air filters remove more than 99 percent of airborne particles regardless of the particle size. Call RAM Air HVAC to find the right air cleaner for your room size and type. As a result, ensuring the clean air delivery rate (CADR) matches or exceeds the square footage of the room you are trying to clean.
A HEPA H13 air filter is capable of blocking up to 99.95% of Maximum Penetration Size Particles
Coronavirus is very susceptible to Germicidal UV-C lights and if it’s irradiated for a certain amount of time it’s inactivated. As a result, it can no longer infect you.
Germicidal ultraviolet light (UV-C) to combat COVID-19 indoors
Ultraviolet Germicidal Irradiation (UVGI) is very effective at damaging viruses. Because germicidal UV has the ability to damage the DNA of microorganisms they can no longer replicate. And COVID is very susceptible to germicidal UV-C.
Moreover, there are two air disinfection applications on the market. Because one application uses fixtures that attaches to the wall or ceiling the UV-C light is beamed overhead across a room. As a result, these upper room UV systems reduce the amount of active virus in the air at a much lower energy cost.
The other application involves placing a UV-C light in the recirculating air duct. As a result, the UV-C lights takes the air from the room you are in and irradiates it. Then cycles the clean air back into that same room.
