Low levels? Yea, I guess 1 cigarette a day is OK for your kids. And
they say 1 or 2 drinks a day reduces heart attacks, so Give The kids A
Beer or TWO !

Ozone exposure limit by EPA for 8 hrs is 50ppb. Ozone output of all
filters I have seen is a minimum 50ppb, 24x7. So although there is
dispursion a tight apt can get an unhealthy level, Ozone is an oxidant.
There are Radiation exposure limits, do you go anywhere near ANY
radiation exposure, not unless you have to. Ozone has just been
recently at a NBC , Reuters article been linked to heart failure. Tests
are underway, research is young, At one time cigarettes were thought
safe. So since indoor air is already polluted with chemicals in most
everything out gassing, Why add more! Oxone is proven in many many
tests to agravate Asthma, Google ,Ozone and its negative health effects.
If the EPA limit is 50 ppb 8 hr. Is there a safe level ??? Why be a
lab monkey. But we are already.
