Are Air Purifiers Safe in Regards to Ozone?
Air Purifiers have gained a bad reputation because of their ozone output; although they were created to produce only 0. 025ppm of ozone for the room space they are intended. This is significantly lower than the CSA and EPA standard of 0. 040ppm and the 0. 050ppm required by many state laws.
There is anywhere between 0. 01ppm and 0. 125ppm found naturally in our every day atmosphere which is also higher than the recommended safe levels of ozone and thus higher than the levels produced by most units. Studies carried out by the University College Dublin showed that certain brands of Air Purifiers operated safely and effectively within the operating conditions specified by the suppliers. Based on their studies, while operated in appropriately-sized rooms, the ozone produced by the units did not exceed the regulatory levels of ppm. Prestigious scientists stand behind the fact that “the units that were tested emit ozone levels that will saturate to less than 0. 05ppm in the room size for which they are designed. “
Based on these findings, the most critical component of owning an air cleaning system is using them in the right size space. If a high output model is placed in a 100sq. ft room, one might find levels of ozone higher than 0. 05ppm. That's because the high output was created to cover 4000sq. ft. When used appropriately, the units work as intended and do not emit harmful levels of ozone. When used appropriately, the units work as intended and do not emit harmful levels of ozone. Just as with anything that is created for an intended purpose, if used inappropriately, the results could be harmful. For example, vehicles have the capability to reach speeds that exceed the regulated speed limits set by each state, but can be extremely dangerous when operated outside of legal guidelines.

Another thing to keep in mind is moderation. The Greeks had it right— moderation, moderation, moderation. If a certain unit is run in a closed off 500 sq. ft. room continuously on high for a month, the air in the room could exceed the safe levels of ozone. Purifier units were designed for average use in the home. On any given day, the units should be run intermittently and only until the room has been cleared of odors or other irritants.
All-in-all, most air purifiers are a very safe and effective way to cleanse the air without being harmful to individuals or to the environment. Other ozone generators that do not adhere to the 0. 04ppm EPA regulatory levels can be harmful to the individual and should be avoided; but, many brands are not ozone generators. They are air purifiers. Their main purpose is to cleanse the air using UV light, Photoplasma, AND Ozone. People who have avoided these in the past can rest assured that their homes and offices will be comfortable, clean, and safe!
