2. In the way of removing Formaldehyde,the difference between ozone and

activated carbon:

The activated carbon has to be put still indoor when using

it to adsorb the formaldehyde.

The air flows slowly indoor which causes the activated carbon adsorbs the

harmful material in a limited space.And it also need to change the filter screen regularly.

If not,it will release harmful material on the contrary.

On the other hand,ozone is gas.

The room can be filled with ozone completely without blind angle.

Then ozone resolve the formaldehyde.

Also ozone is widely recognized as the most efficent bactericide in the world.

Hospitals have already replaced UV lamp with ozone generator.

we can notice with our sense of smell and dodge away or take actions to avoid

further leakage.

So far there is no one dealth reported caused by ozone poisoning.

4. Does the ozone generator work efficently ?

Undeniably,ozone can clean and remove odor and formaldehyde.

It is reported that ozone is a widely used bactericide.It can kill escherichia coli,

bacimethrin efficently and resolve the harmful material in a short time.
