air deionizer

Ionizing air filters are extremely effective at removing small particles such as smoke.

If you are referring to negative air ionisers they work very effectively as well....

Not sure what your question is about specifically??

John.

are you referring to removal of static charge or particular type of charge already present in the environment. Air cleaners are negative ion generators and simply spark thru air high voltage sources with corona discharge and some fan.

Ionic air cleaners do work well, and have been used large-scale in industry for years. Remember (if you're old enough) how dust used to get attracted to the static charge on the front of your TV picture tube? Basically the same thing. In the air cleaners, however, high static voltage charges a series of metal plates. As small particles (such as smoke) pass between the plates they are attracted and pulled from the air. Of course, from time-to-time the plates have to be cleaned to maintain their effectiveness.

Negative ion generators, serve a different purpose. Some people believe that human beings feel better when the air about them has a relative negative charge. This occurs at the beach, for example. Sea air is relatively negative in charge. Positive ions are believed to make humans feel not good. For example, smoggy days are said to be times when a lot of positive ions are in the air. So, several companies have come up with electrostatic devices that keep the charge of the air in a room (for instance) at a negative level. Do they work as promised? I don't know. Get one (or borrow one) and find out if it makes you feel better.

Vermin, those negative ion generators do work well, they do have a good effect on health and well being for humans...

Back in the 70s we experimented with them for fun, but were quite surprised at how the mood of an individual did change when the ioniser was switched between negative, off and positive ion output.

The results were obtained at work at Marconi's with the subjects not knowing what the ioniser was set to, sort of blind testing... Quite interesting.

John.

I fully believe you, but where are they?! I'd love to get my hands on one and see if it makes my burrow any more livable. Any suggested manufactures?

I've got an old one sat in my lab somewhere...Like a lot of stuff "it may come in useful one day" !!!

All it is is about a 14 stage voltage multiplier using 1N4007 diodes and 0.01 microfarad ceramic caps, just plug it into the mains 240 volts and you get a cracking 4 to 7 kilovolts out...

Blerdy lethal!!! but good fun!

John.

Not to mention the lethality of the 240 Volt AC mains!!!

Remember (if you're old enough) how dust used to get attracted to the static charge on the front of your TV picture tube?

With a lot of the programming, this is a good use for the TV.

I concur!

And heck, I didn't want to tell him to look inside the TV where the dust is standing on end over two inches thick!!!

When the technology first became popular, numerous (small) manufacturers of other products [e.g., steam irons, vacuums] jumped on the bandwagon and cranked-out their own spin-off versions of this type of air cleaner. Some work quite well, others were engineered rather sophomorically and performed accordingly.

American Lung Association has some good links regarding the different types of cleaners, and other "Indoor Air" facts at:
http://www.lungusa.org/site/apps/lk/links.aspx?c=dvLUK9O0E&b=36056

A variation, of sorts, is the air ozonator. Though hazardous to the human respiratory system in even small quantities, ozone has proven itself to be very effective for killing microbes in water (potable water, pools and spas). And, although they are NOT recommended for use as air cleaners in inhabited areas (see EPA link below) they ARE the proverbial "Cat's Meow" (for you, Del) when using commercial grade equipment, to rid a house, apartment complex, etc. of mold and fungus infestations (basements, living areas, ductwork, etc.) WHILE VACATED, just as you would vacate for termite fumigation. As the EPA link says, the ones that are sold for perpetual cleaning of the air in a residence are NOT effective for that purpose ... tho they ARE effective at causing many adverse reactions!

Wishing you well ~

Don't put yer lips on 'em!

The best on the market is AIR OASIS.COM check them out!!!

Thanks! Will do.

Beware of one thing though. If your place is full of fine particles floating around like cigarette smoke or extremely fine dust these will settle all over the place. Your air will be clean but you will have a job on your hand keeping the place/furnishings clean.

Another thing to watch out for in these desktop ionizers is that quite a number of them produce ozone. So make sure that you get one that has been independently tested and approved.

Best place to look these approved types would be "Consumer Reports".

For a manufacturer of excellent air purifiers see:

http://www.alpineairproducts.com/

I am sure there are some just as good on the market, but I think these are the best.

all the purifiers on that webpage produce OZONE which is bad for you. Also they all are just like ECOQUEST products, and are not suppose to be sold on the net. I am certified in indoor air quality and the use of ozone as well as many other things. I would not use these products in my home and would say you shouldn't. The best company for ACTIVE AIR PURIFICATION is AIR OASIS www.airoasis.com

Hello sir, I am the GreatEagle1 here and I figured out something you guys have not figured out like two things now !!! one question to you ok is how do you use the energy of electrons to get energy at the end ?? Hint only one hint guys here seriously all electrons are part of the magnet !!! I could put a diagram here but you know who would shut or have it deleted here plus they will be watching me even closer !! You guys know who Stan Meyers is yet if not check out his videos on youtube. ok enough of that so your opinions on this site is the best and why you think its the best ? please explain to me why and how does it work thanks

Hi

I am using these since now around 30years,

I put a sheet of paper or aluminum foil beneath not to have problems with accumulated dust, connecting a copper wire below this sheet will greatly improve the efficiency and restrict the dust stained area.

The needle like points made from tungsten where the ions are produce need resharpening from time to time as there is some erosion.

The voltage there shall be restricted to -4.5KV as at this level there is no ozone production but above there is and ozone is very poisonous.

You can run into severe trouble with this device with capacitors of medium to high voltage specs nearby. These collect the charge until breakdown - I assume there is always one of the pins with a lower resistance to earth than the other. So if you touch one pin only you won't feel anything until breakdown occurs - and this may kill you. (In this situation your body is the low resistance path and the other pin the ion collector.)

Sensitive people will feel and suffer much less from existing or coming bad wheather if using these.

So what's the REAL story about ozone?!

When I was a kid, my train set recked of it, and mom's dryer generated it to disinfect the close. And almost every laserjet printer gave it off... So am I brain damaged or lung damaged or what.

And don't say I've just answered my own question!

IF YOU DO OZONE TESTS WITH THESE UNITS RUNNING YOU WILL SEE THAT THE LEVEL INCREASES TO UNSAFE LEVELS OVER TIME. IF YOU STAY IN THE AREA LONG ENOUGH YOU WILL GET PREMENANT LUNG DAMAGE. I HAVE BEEN TO CONVENTIONS FOR THE COMPANIES THAT MAKE OZONE AIR PURIFIERS AND IT'S FUNNY BECAUSE EVERYONE WEARS THE LITTEL ONE AROUND THEIR NECK AND THEY ARE ALWAYS COUGHING AND CLEARING THEIR THROATS. I ALSO HAVE HAD MEETINGS WITH THE TOP PEOPLE IN THE COMPANY AND OZONE IS ALWAYS TALKED ABOUT BECAUSE OF THE HEALTH CONCERNS. THE STATE OF CA. WAS WORKING ON SOME KIND OF BAN ON THESE UNITS SO THE COMPANIES NOW MAKE SPECIAL UNITS FOR OZONE RESTRICTIONS HERE AND IN OTHER COUNTRIES LIKE CANADA. BOTTOM LINE IS YOU CAN TRY TO MAKE LITE OF THE TRUTH BUT IT IS THE TRUTH OZONE IS BAD FOR YOU!!!!! THEY EVEN TELL YOU THAT IN THERE BOOKLETS.

I assume by the uppercase type that you're yelling at me. I was not making lite of this. My experiences with ozone are as I described.

So, am I safe in assuming that ozone can be smelled in smaller amounts than that which is dangerous? If yes, what level in the air is considered damaging?

Hi,

ozone is splitting into atomic and molecular oxygen, The atomic oxygen will react very fast with any organic material (except pure carbon).

The severest attack will be on the wet surfaces in nose, throat , bronchial ducts and lung.

If the damage is light then the mucosa will regenerate after some healing process.

If severe you may have to live with non wetting surfaces of mouth, nose and troat, I am not sure but I estimate that nobody will survive this severe damage if in the lungs.

If cells are attaced (by this or other oxidising agents) during cell division then it is likely that DNA replication is not correct.

This will result in cancer cells with a low probability so it takes some time and multiple exposures to get cancer by this or other prolonged or recurring injuries.

(In the mean this is correct but as an individual the risc is with every exposure.)

Early laser printers had an ozone remover , a filter covered with fine particles of charcoal. I did not look into a modern one.

So this action is belonging to a class of poisons that will add up the risc until a permanent damage, usually in the form of complete surface tissue killing or in the form of cancer generation is existing.

Asbestos fibers and radioactivity are similar.

It needs only 11eV for Ozone production so 4.5keV is a lot of voltage and energy source for electrons to get accelerated, hit and ionize O2 atoms. If you believe you have no Ozone then you can also believe that UV of 11eV can not produce Ozone. In fact all vacuum UV in 10eV to 30eV range do a lot of ionization of air and generate high energy UV.

Perhaps if you pulse ark for a while and reduce active time then some reduction is possible. Take care as only 0.7ppm of O3 in air for an hour is permissible else will leave you without functional neurons and your memory will not be worth counting your bank transactions.

It sure works as long as hardware is fine and power is applied. Too much humidity may cause problems of low voltage discharges.
