Cinnamon oil, Eucalyptus oil, tea tree oil, lemon or lemongrass oil. Lavender & of course clove oil. Try them in a mix of scents you like by mixing in a bottle three parts water (small bottle) a tsp. or less of Vodka, a few drops of your favorite oils (listed above) and if you do not like the smell just try and do your best to deal with it because they kill off these viruses. You do not get the chemicals in these other room sprays and I am sick right now so I am going to make up some sprays I have not used in months. I use diffusers but not the sprays like I should. Give it a shot. It cannot hurt.
