Hi A.,
As a mother of ten, six still living at home...every winter I break out our purifying humidifier that has a little touch of ozone to make sure humidity I generate doesn't result in harmful bacteria...ozone at a low level is a better sanitizer than bleach & far more pleasant. It compliments our air purifier that also sanitizes and removes allergens, odors even smoke.
If you care to know where I got the Pursonic Mister...let me know.
