Almost all essential oils have some degree of anti-microbial activity. The oils in this table are best known for their antiviral and/or antibacterial activity. They make the perfect choice for a diffuser blend to disinfect a room. Not only can they cleanse the air of the nasties, but studies have shown that hard surfaces in a room are also disinfected when essential oils and diffused. Oils in bold font are most frequently noted for their antimicrobial properties. If you have a favorite oil or blend for room disinfection, please leave a comment below.

i have a COPD .Which oil is best for better breathing? and Which oil is better antibacterial and antivirus for diffuser use. Thank you.
Hello,
In the chart above most are good in a diffuser for either bacteria or viruses. Lemon, oregano, tea tree, cinnamon, clove, and eucalyptus are good anti-viral oils. Bergamot, eucalyptus, lemon, lavender, pine, and tea tree are good anti-bacterial oils. I am not a doctor, so I don’t feel comfortable making recommendations specifically for COPD. My personal feeling is using essential oils for serious health concerns should be done under the supervision of your doctor and/or a qualified aromatherapist that can review your medical history personally. It would be irresponsible of me to make a blanket recommendation. I hope you understand and are able to find someone to help you with that.
