Novel Coronavirus Virus Particles in the Air

This morning it was reported that yet another study found that the coronavirus virus could suspend in the air for as far as 16 feet.  Traditionally, the focus on sanitizing is on cleaning and sanitizing surfaces.  More frequency for sanitizing the common surfaces like door handles, countertops, and elevator buttons is the well-known strategy during an infectious cycle.  See: CBS Report

We depend on the cleaning crew to step up their efforts to clean and sanitize surfaces, but we also know how quickly they can be compromised.

But, there is a huge increase in awareness that the coronavirus is being spread through the air and not so much by touch.

The hard question is how to constantly treat the air to kill any airborne pathogens.  Even spray or fogging systems are good routines to treat all surfaces and the air, they are a "Moment in  Time" solution.  What is a better solution in light of the growing knowledge of how the coronavirus is spread?

How about a nightly 30-60 minute ozone treatment that will sanitize the air?  Studies have shown that a short nightly ozone treatment can will infectious bacteria and viruses in the air.  All that is needed is a unit with a two-fold timer.  One for the delayed start, and one for the duration of the treatment.  The 32G ozone generator from has both timers built into one system.

The next choice is to install a hydroxyl generator that runs 24/7 in the background.  There is no smell or health concern when running hydroxyl generators in the building.  The good news is that they are constantly treating the air.  So, any potential infectious threat is being sanitized even as it is introduced.

Both ozone and hydroxyl systems are oxidizing systems with a unique approach.  Ozone must be applied only in vacated areas or when no one is in the building.  Hydroxyl generators can be safely operated with people and normal activity in the building.  Ozone is run for 30-60 minutes at night when people are out of the building.  Hydroxyl generators are operated 24/7 because the system requires much more time to do the sanitizing that ozone does more quickly.

By comparison, ozone generators are more affordable, and there is a pool-like smell that lingers after the treatment.  Allows several hours after the treatment for the air to clear by adjusting the start and run time.  Hydroxyl generators are more expensive and treat 1000 to 6000 sq ft depending on the size of the unit.  Buildings will need more than one unit or need to move the unit(s) from room to room each 24 hours to cycle the whole building in a week's time.

The additional value is that both ozone and hydroxyl systems will remove odd odors, cleanup the toxic or sick building problem, reduce worker, customer, or student allergy or health concerns.  Indoor air quality will definitely improve by using these systems.  By contrast, the heavy use of cleaning and sanitizing chemicals often add toxic chemical residue to the building.
