Portable air purifiers used in a public hospital in Melbourne, Australia cleared 99% of aerosolized glycerin particles in a patient room within 5.5 minutes. Researchers substituted glycerin for viral particles
The Environmental Protection Agency also recommends the use of portable air cleaners or HVAC filters to reduce viral load in indoor areas. Portable air filters should be designed to remove smoke and not pollen or dust, which are much larger than viruses
Energy efficient new homes lack adequate ventilation, which can increase the risk of indoor air pollutants, including viruses. The EPA recommends proper ventilation with outdoor air to reduce airborne contaminants, which lowered the spread of COVID-19 in one study 2% more than wearing masks
In addition to lowering the viral load, it is important to support a healthy immune system through optimizing vitamin D, eating within a compressed window of time, eating the right type of fat, making time to exercise and trying to make a sauna part of your routine
