VENTILATION

To eliminate 99+% of the Viruses and Pathogens from spreading in our Homes, Buildings, Businesses, and Schools, Air Thermal HVAC & Refrigeration recommends using UV light with Ionization technology to eradicate over 99% of harmful bacteria, molds, allergens, and viruses throughout HVAC Systems.                    

Enclosed areas without ventilation are the most vulnerable in the spread of molds, bacteria, and viruses throughout HVAC Systems; in addition, ductless HVAC Systems, such as mini-splits and PTACs (Packaged Terminal Air Conditioner) also circulate molds, bacteria, and viruses including Covid-19 and its variants, especially when relative humidity levels are higher than 50 to 60% ª, which is the comfort level for humans -- Especially worrisome are non-ventilated elevators, non-ventilated houses & buildings that are subjected to SBS (Sick Building Syndrome) and BRI (Building-Related Illnesses), vehicles, airplanes, transport buses, bars, and restaurantsᵇ.

More Importantly, even ventilated homes and buildings are subjected to Airborne Contaminates, like, molds, bacteria, and viruses that are scaled down to 0.1 μm (Covid-19 & SARS-CoV-2 is an enveloped virus ≈ 0.1 μm)ᶜ; CO² molecules, for example, are 0.33nm in diameter – several orders of magnitude smaller than ALL CORONAVIRUSES and readily circulate throughout HVAC Systems, as well as Ventilation Systems and, as a result, are a concern for Ventilation Engineers for building occupants that might enter ventilation systemsᶜ (bars and restaurants provide less transmission of viruses when outside and social distancing is practiced because you're in a well-ventilated environment, but you're still exposed at a reduced risk); for these reasons, masks and eyeglasses should be worn to mitigate transmission, according to CDC guidelines -- MOST viruses and bacteria detrimental to humans prosper in high humid environments, such as your lungs -- relative humidity levels of and below 50 to 60% have been shown to suppress bacteria and viruses on surfaces harmful to peopleª, as well as sunlight exposure while maintaining social distancing -- One technology that has been documented in University Case Studies (Link Below) funded by the CDC (Center for Disease Control and Prevention) to reduce molds, bacteria, and viruses are self-cleaning ionizers, carbon fiber brushes, and ultra-violet light utilizing an enhanced zinc ceramic catalyst for superior bacteria and virus reductionᶜ; in fact, this technology, along with HEPA filtration is used in hospitals, schools, medical facilities, planes, and residential homes to mitigate mold, bacteria, and virus transmission in humans.
