‘According to the Environmental Protection Agency (EPA), indoor air quality can be two to five times worse than outdoor air quality. David Bloom, chief science officer of Green Home Solutions, says that it’s not unusual to see indoor air quality levels even worse than that.’①
‘In the western countries, people usually spend 90% of their time indoors. The average American spends even more than that 93% inside buildings or cars. For years scientists have sounded the alarm that our disconnect from the outdoors is linked to a host of chronic health problems, including allergies, asthma, depression, irritable bowel syndrome, and obesity. More recently, experts in various fields have begun studying why buildings, even those designed to be as germ-free as possible, are vectors for disease, not the least Covid-19. Now, with a global pandemic raging, these researchers are suddenly in demand.’ ②
Of course, the most urgent question is where to find SARS-CoV-2 and how to kill it. Beyond that, there are also long-term questions. How can we promote indoor microbe populations that don’t make us chronically ill or harbor deadly pathogens?
How to keep the indoor air safe?
“Nearly all indoor air pollution, depending on the intensity, can be controlled with “proper ventilation, filtration and in some cases, additional air treatment devices to eliminate bacteria, viruses and other unwanted material,” Mock says.”①
- Introduce fresh air: If the outside air in your area isn’t affected by wildfires, dust storms or other natural disasters, letting fresh air in can help. “This may sound silly, but often ‘the solution to pollution is dilution,'” Bloom says.
- Clean AC regularly: Keeping your AC ducts clean is probably one of the best things you can do to improve your indoor air quality, Bloom says, as is using a high-quality AC filter.
- Invest in an air sterilizer&deodorizer: LIVA air serilizer&deodorizer, can remove dust, pollen and PM2.5 particles, inactivate bacteria, viruses and microorganisms and decompose the volatile chemical gases and remove the odors.
Why LIVA air sterilizer&deodorizer can make it?
Primary filter: removes large particles of pollutants such as dust and pollen;
Activated carbon filter: removes harmful gases and odors;
HEPA (H13) filter: removes particles such as PM2.5;
Under UV-A irradiation, titanium dioxide (TiO2) will produce highly active hydroxyl radicals (OH). OH has strong oxidizing properties and can quickly decompose viruses, bacteria in the polluted air, finally form harmless water.
After testing by the authorized lab, the sterilization rate of Human Coronavirus can reach 99.99% in 1 minute. ‘disinfections by titanium oxide are 3 times stronger than chlorine and 1.5 times stronger than ozone’③
Activated carbon filter: Absorbs formaldehyde, benzene, etc;
TiO2-based photocatalysts: Oxidize organic and inorganic compounds;
- Unique design of zigzag sterilization module:
TiO2-based photocatalysts: the zigzag design of the sterilization module increases the reaction time between hydroxyl radicals (OH) and air pollutants, LIVA air sterilizer &deodorizer is equipped with four sterilization modules, and the airflow will be sterilized for 6 times.
