What is the working principle of an Electronic Air Cleaner?.Do they really work???

Ozone is a toxic gas. The extra oxygen atom in the unstable ozone molecule looks to chemically combine with another molecule.

Low concentrations in the air can cause chest pain, coughing, shortness of breath, and, throat irritation. It worsens respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.

You are better off with a electrostatic precipatator to remove dust particles from the air.
 

@ninju...thank you...then if we switch on a mosquito zapper bat,then is it ionize the surrounding air molecule???...then if it ionize the air then that will result in the anions and cations,and I think the anions will attract the dust and other particles from the air....But we can't see anything like that in the net of a bat???..why?...I am not sure about about my doubt is a childish one or not..:).but I would like to know that

@dick_freebird..thank you....but I think its not easy to collect a ignition coil:(....Can I make a circuit as my own??....from ninlu's opinion,can we use a mosquito bat's circuit for this???

@tpeter,But I would like to design one as my own....I think its more interesting to design as my own than buy one from market...

@RCinFLA...Then is it risky to use a air purifier(With an ionizer)??....or any method to avoid the formation of ozone here??...
 

Air Ioniser

This circuit uses 12V low voltage and transformer to make HV. In post #6 is circuit which multiply mains voltage from 220V.
 
@tpeter..Thank you very much...I wish to try this circuit...first I want to collect an ignition coil....By the way is there any problem with the ozone here??

@tpeter..thank u.now i got a clear idea about ionizers,..nw im gonna design one:)
Click to expand...

Just keep in mind that this is HV and work with caution.

Ozone is a naturally occurring gas created from oxygen atoms. The oxygen we breathe is made up of 2 oxygen atoms. These oxygen molecules are broken into atoms by the corona discharge during lightning storms or by UV light from the Sun. Single oxygen atoms cannot exist alone without regrouping back into di-atomic oxygen molecules. During this recombination stage some atoms will regroup into loosely-bonded tri-atomic oxygen. This new molecule is called Ozone. Due to the loose bond in this oxygen molecule - ozone is a very strong oxidant and an ideal chemical-free purification and disinfecting agent.

Ozone is very unstable and must be generated at the site of its intended use. Portable ozone generators create ozone at the point of use. Ozone has a half-life of from 10 to 20 minutes, depending on atmospheric conditions. It reverts back to O2 in a short time.

Ozone is frequently misdiagnosed and equated to low-altitude pollution. Nothing could be farther from the truth. In fact, Ozone breaks down air pollutants.

Effects of ozone on human health

Even very low concentrations of ozone can be harmful to the upper respiratory tract and the lungs. The severity of injury depends on both by the concentration of ozone and the duration of exposure. Severe and permanent lung injury or death could result from even a very short-term exposure to relatively low concentrations.

Exposure to ozone during exercise or work increases susceptibility to this effect. Increased bronchial responsiveness has been observed following 7-hour exposures to 0.08, 0.1 or 0.12 ppm (with moderate exercise), or a 1-hour exposure to 0.35 ppm. This response occurs almost immediately following exposure to ozone and persists for at least 18 hours.

Other symptoms observed following acute exposures to 0.25-0.75 ppm include cough, shortness of breath, tightness of the chest, a feeling of an inability to breathe (dyspnea), dry throat, wheezing, headache and nausea.

An acute occupational exposure to approximately 11 ppm for 15 minutes caused severe respiratory irritation and almost caused unconsciousness. A 30-minute exposure to 50 ppm is considered potentially lethal.

Ozone concentrations greater than 2 ppm can be irritating to the eyes within minutes. No definite effects on vision were noted in volunteers exposed for 3 or 6 hours to 0.2-0.5 ppm, although some increase in side vision (peripheral) and a slight reduction in visual sharpness (acuity) was noted during dark adaptation tests.

You can make Ozon (O3) detector to test your device.
 
@tpeter....thank you very much........lol..may its my last reply :):)....By the way is it easy to design an Ozone detector??...I think its better to design an ozone detector first...:)

That links are very useful:)
 

Actually I am from a rural area.....so I think its not easy to get an ozone sensor....:(...anyway I am gonna design an air cleaner:)
