Op, it's not healthy to live in a sanitised environment particularly if you have children or animals. Google it.
Sadly some people don't understand what a discinfectant is, or when they should be using it, they think zoflor is some cheap way to make your house smell good, like an air freshener. It's not.
As said, you should only be discinfecting, if you've had sickness in the house. Past that, just clean normally. Using zoflora is no different to using pure dettol or any other discinfectant.
