Has anyone noticed that when using electronic air cleaners in a foam insulated home the smell of ozone? Does the Ozone concentration increase when these units are operated 24/7 in house that is tightly sealed!? i.e foam insulated homes...
I just read this study from European Commission Joint Research centre, Institute for health and consumer protection. Here is an excerpt.
6 RISK MANAGEMENT OF OZONE – RECOMMENDED IDEAL PRACTICE
For managing indoor ozone concentrations, there are two practical management options: 1)
to manage the entry of ozone from outdoor air and 2) to minimise indoor sources of ozone.
Typically outdoor concentrations of ozone are higher than indoor concentrations.Therefore,
in the absence of indoor sources, outdoor air is the driving force for ozone concentration in
indoor air. In practice, this means that keeping windows open or otherwise increasing the air
exchange rate, especially in hot summer days, when outdoor ozone is typically at its highest
level, will increase indoor ozone levels.
It is also recommended to use mechanical ventilation, which removes ozone by surface
reactions in air channels. Especially, if refrigerating cooling of incoming air is not available,
the use of active carbon filters is recommended to decrease indoor concentrations of ozone.
Ozonisers should not be used in indoor environments. Indoor ozonisers are marketed as
indoor air purifiers, while in reality they add a new direct source of toxic air pollution – ozone
– and secondary source via highly irritative reaction products of ozone with someVOCs such
as terpenes. It should be ensured that ozone emissions from devices commonly used indoors,
such as printers and copy machines or other electrical devices are minimised.
It is recommended to minimiseVOC emissions from the materials and products that are used
indoors, because reactions of ozone with VOCs produce compounds that might be highly
irritant. Therefore, it is recommended to develop harmonised European wide emission
labelling systems to avoid unnecessary VOC emissions indoors.
I believe that the American Standard Clean Effects is producing 0.03ppm of Ozone on the highest setting. Once again does this ozone level accumulate in a tightly sealed house to unhealthy levels?
