stands in the fight against
Coronavirus (Covid-19)

In championing the air we breathe,  5 DIAMOND MECHANICAL stands in the fight against coronavirus (COVID-19).  The airborne nature of this coronavirus puts it as a priority for its prevention and containment — 5 DIAMOND HVAC professionals are front and center of this fight. Our priority will be keeping our employees, and families safe. 5 DIAMOND MECHANICAL will be aware of what technologies are available informing, educating, and assisting our concerned clients so that improved air quality and safer homes and offices are a tangible reality.

One of the big questions about COVID-19 — especially from an HVAC perspective — is how significant of a role airborne transmission plays in its spread.

The current consensus is that it’s predominantly large droplet transfer. This means droplets too large to remain airborne that are spread through coughing and sneezing within a fairly close range of other people. The Center for Disease Control (CDC) puts this range at about six feet. Because small particles remain airborne for some period of time, the design and operation of HVAC systems that move air can affect disease transmission in several ways, such as by the following:

  • Supplying clean air to susceptible occupants
  • Containing contaminated air and/or exhausting it to the outdoors
  • Diluting the air in a space with cleaner air from outdoors and/or by filtering the air
  • Cleaning the air within the room
  • How to best protect occupants from exposure to the virus, in particular in relation to airborne particles that might be circulated by HVAC systems.

 5 DIAMOND MECHANICAL  is recommending the iWave-R Air Purifier along with a high MERV rated filtration.  The iWave-R uses a needlepoint bi-polar ionization generator to create positive and negative ions which actively purify the supply air, killing viruses, mold and bacteria in the living space. By removing these and other unwanted particles from the air, indoor air quality improves and makes for a healthier indoor environment.  iWave-R treats the air in any brand HVAC duct air system up to 6 tons, is self cleaning and requires no maintenance.  Filters with a high MERV rating are designed to capture particulates in the air … while the iWave-R ionization is effective at inactivating pathogens. iWave-R systems have also been shown to reduce microbial load and pathogens that are found within the HVAC system and drain pan that would otherwise be introduced and distributed throughout the building.

Since COVID-19 is transmitted via air and direct contact, it could be presumed that HVAC systems that are not using a high MERV rated filter and or an iWave-R system can inadvertently facilitate the movement of viruses. Airborne droplets containing infectious agents can remain in room air for six minutes and longer. Scientists have found that COVID-19 can remain infectious on surfaces at room temperature for up to nine days.  

5 DIAMOND MECHANICAL recommends upgrading filters to a MERV 14 or higher to capture the COVID-19 airborne droplet nuclei and droplets.  The World Health Organization has defined airborne droplets and droplet nuclei of COVID-19 to range from 0.5-5.0 microns in size. The NAFA  ASHRAE 52.2 chart (available upon request) shows the MERV 14 is highly efficient in capturing this particular size.

5 DIAMOND MECHANICAL is committed to providing the very best in HVAC. Join us in our fight against COVID-19.  Have a regular maintenance schedule for your system. Use high MERV rated filters. Install an iWave-R air purifier. Please Be Safe. Please Be Well.
