Disinfection Practices for Covid and other germs and viruses

For the past 17 years that i have been licensed and practicing massage, I disinfect the massage table, head and arm rest using 70% isopropyl rubbing alcohol after each and every client. I mix this with water to the CDC recommended ratio of water to alcohol. The 70% alcohol is very important because it is mixed with water at the manufacturer which  acts as a catalyst and has a major role in denaturing the proteins of cell membranes of vegetative cells. That is, the water opens the cell membranes so the alcohol can easily kill the cell. It also slows the evaporation rate allowing the alcohol time to do its job. 

I have a medical grade HEPA air purifier that filters out 99.9% of particles down to 0.1 micron.
