Does tpp220m hepa type air purifier produce ozone

The HEPA certified air purifier by far has been the best type useable since it is very efficient. The most advantageous aspect of this type of air purifier is that does not emit any by-product or secondary pollutants like ozone that is so very harmful. Buy certified HEPA filter air purifier to maintain the freshness of the room.

The graduations are incremental for your ozone output for the purifier control. Generally, the machine can put out enough ozone to cover 3000 sq ft. (when the control is moved all the way to the right, about 5 o'clock.) Half way should be about 1500 sq ft or 12 o'clock. For general air cleansing, you should set the purifier control to produce enough ozone so you smell it when walking into the room (after home) for about 30 seconds. The ozone smell should disappear after that. If it lingers, you've got it set too high. For more severe odor control you can set it higher but remember that some of us are more sensitive to the odor no matter what the setting. It may need some adjustment based on your individual preferences.

I'm confused about the 'red plates' as you mentioned. The original machine comes w/ 2 ozone plates (made of glass) and doesn't produce ozone when one of the plates is removed. I'm guessing that the lines may tell you when you're engaging both plates to work, i.e. more ozone being produced & blown into the room or less only calling on one plate to produce ozone. If you send me a close up pic of the control panel I may be able to tell you more.

HEPA is a type of air purifier. It stands for high-efficiency particulate air. To qualify as a HEPA filter by government standards the filter must remove 99.7% of all particles larger than 0.3 micrometers from the air. The following site lists the top 10 HEPA purifiers available online - http://www.air-purifiers-america.com/AP101_top10.asp.

Try checking the contacts to the ozone plate. Or a wire may be loose--check the contacts and sometimes they need to be cleaned with alcohol.

the UV lamp does produce some ozone .. this one specifies .04 ppm .. thats not very much but might be detectable as a slight fresh air odor .. some other types use electrostatic filtering and some even have strong ozone generators .. ozone does kill bacteria, fungus and such and will freshen the air removing many odors but is not considered healthy in large or concentrated amounts or for prolonged periods .. the UV lamp will also kill bacteria and fungus without producing so much ozone.

Purifying Method: Photoplasma, UV, ions, and ozone.

Any system using electric currents are deadly OZONE producers if your ozone producing machine is broken pleas don't fix it replace it look for any system with a filter not a electric current burning all the dust

no but your uv ligth its burn out

Strictly speaking it is both and neither! It incorporates a high voltage source (18kV) which has the potential to create ozone, though the manufacturer does not claim that ozone is the means by which micoorganisms are defeated. It also incorporates an 85% efficient HEPA filter, but teams it with EMF technology (their own patented technology using the 18kV energy field) to increase the HEPA efficiency to 99.99% (their claim).

Mine has a switch lower right hand side that will stop the ozone.

The Food and Drug Administration requires the ozone that is given off by medical devices that are used indoors to be no more than 0.05 ppm. If you have a manual, does it specify the amount of ozone given off? I'd be interested in the figure.
