Just install an app on your smartphone, (included, very easy to install) and you can turn your ozone generator on and off from anywhere in the world. (via wifi) This is a GREAT outlet to use with our ozone generators. It also has a timer and countdown timer feature, but the feature that works best is merely being able to manually turn the ozone generator on and off via the cell phone app.
Performing regular shock treatments when you (and your pets) are away from home will sterilize and sanitize your air and your surfaces and kill molds, bacteria, viruses, fungus even dust mites. Ozone shock treatments when performed on a regular basis I believe is the single most important thing one can do to keep from getting sick (besides drinking clean water and good quality food). If you suffer from allergies, Instead of wasting money on drugs, consider doing regular ozone shock treatments to kick the molds and micro-pathogens that are making you sick to the curb once and for all!
If I have four units with 4 timers, can the app manage them all at once?
Yes, each timer shows up on the app as a separate timer, you name it (bedroom, kitchen, etc)
I have Wi-Fi on my cell phone but I do not have Wi-Fi in my home in order to reduce EMF Is it necessary to have Wi-Fi in the home for this app to work.?
If your phone emits a wifi signal, then you can use this. I thought cell phones only emit a "hot spot" signal, not a wifi signal per-se. Ask your phone carrier if the signal it emits is considered a wifi signal.
