How much ozone does the aprilaire 5000 produce?

Consumer question:

I was reading the most recent CR evaluation on air cleaners and they warn against ozone generation by some cleaners. There was no mention of ozone in your FAQ. How much ozone does the aprilaire 5000 produce?


Aprilaires' response:

Aprilaire shares our customer’s concerns about ozone, and wants to reassure you that our Model 5000 Whole Home Electronic Air Cleaner is not designed to produce a significant amount ozone.

Ozone is produced as a result of many factors, some are man-made and some originate from nature. On any given day in the US, outdoor levels can be as high as 150 ppb.  More polluted areas typically have higher outdoor ozone levels because there is a greater concentration of the components that create ground level ozone. 

Levels of ozone inside our homes typically range from 10 to 70 percent of the level found outdoors, primarily depending on whether windows and doors are left open. (ref. “Ozone Decay Rates in Residences”, Harvard School of Public Health, Environmental Science and Engineering Program).  The reason indoor levels are lower than outdoor levels is because ozone readily reacts with other gases and surfaces.

As a manufacturer we look to government organizations to set the standards as which to develop and produce products by.  As such, we offer an air cleaner that produces 2 ppb, well below the established FDA standard of 50 ppb for medical devices and the UL standard to evaluate products for consumer safety.

The high voltage power supply contained in this (and any other) electronic air cleaner produces ozone only as a byproduct of operation; the small amount of ozone generated dissipates by the time clean air filters out and into your home. In addition, the Model 5000 removes particles from the air that have proven by research to be harmful to humans. 

There are a select group of people who are sensitive to ozone.  For these people, we recommend using the Aprilaire High Efficiency air cleaners Model 4200 or 4400.  For everyone else, the Aprilaire Model 5000 is the best air cleaner for your home.

you did NOT answer the question...
So can you try again: How much Ozone does the 5000 produce, and while you are at it, what is the ozone production for the 4200 and the 4400.

It says right above "we offer an air cleaner that produces 2 ppb" which doesn't seem like much. But I'm looking for a report that indicates that as I had planned to purchase a 5000 and searching google I can find nothing that gives me a degree of comfort in selecting this even with that small amount of ozone. I have a child with asthma so there is a concern and I'm running out of time to purchase as I want one very soon.

Thank you for contacting us. The ozone that is produced dissipates in the air and is broken down into the environment turning into oxygen. The ionizing frame within the air cleaner charges the particles that pass through the ductwork and the filter captures the charged dust particles. The ozone that is produced starts to get broken down after it is produced and passes right through the filter and the 2ppb of ozone that enters the environment is the ozone that did not completely breakdown yet.
The 5000 electronic air cleaner is the only air cleaner that produces ozone.
Please let me know if you have any other questions.

Thank you for giving us the opportunity to be of assistance.
