So who can confirm that an air ionizer can generate negative ions without producing ozone?

what is your job

to purify the air, the base is 15m3H per person
it's very easy with a small device with a microparticle filter

what is the interest of the ionizer?
- very delicate to use
- requires regular maintenance
- measurement of ozone production not easy to control

to sum up a lot of worries about an air filter

The regulation is 20m3 / h and per person minimum for the hygienic air renewal, the flow rates will be variable for the air purification, but filtering the air especially in recycling would tend to deplete the amount of negative ions which will stick to the filter

I wonder if there has been a comparison between an ionizer and a filtration system, in a school for example to see if the rate of absenteeism reduced ...

http://www.naturavox.fr/article.php3?id_article=1846 a écrit :Indoor air quality
The Indoor Air Quality Observatory (OQAI) conducted a campaign on air quality in housing in mainland France over the 2003-2005 period. This study targeted around thirty chemical, physical and microbiological pollutants. It has been pointed out that there is specific pollution inside the housing that is not found outside or in a lower concentration.

Volatile organic compounds (VOCs)

The campaign has shown that 10% of dwellings have very high concentrations for several pollutants simultaneously (2 to 20 times higher than the median values ​​of the overall sample); conversely, 45% of dwellings show significantly lower concentration levels for practically all of the compounds measured. 15% are still associated with high to very high concentrations for 1 or 2 compounds (5 to 400 times).

For 18 of the 20 compounds measured, the indoor concentrations are significantly higher than outside. The percentage of French dwellings with higher contents of volatile organic compounds (excluding glycol ether) inside the dwelling than outside varies between 68 (trichlorethylene) and 100% (formaldehyde and hexaldehyde).

sure, nothing replaces good ventilation with the energy losses that go with it, so you need a double flow system with energy recovery
So, in the absence, can an ionizer do the job?

There "would" be other virtues of ionized air, such as ensuring better pulmonary exchange ...

true? false? I would like to know, nothing official in everything I see

yes that's exactly the solution ...

AIR IONIZERS
certified without ozone
Fees :
Air ionizers are devices that emit billions of negative oxygen ions per second (4000 billion). Their goal is to raise the level of negative oxygen ions contained in the ambient air to around 8000 (mountain air)

The oxygenation of the air approaches that of mountain air.
These devices find their place with asthmatics, respiratory allergies but also in nurseries, hospitals, offices, wherever the air needs to be enriched.

PLACES CONCERNED Negative IONS per liter
Waterfall foot .. 50000
Mountain .............. 8000
Seaside .......... 4000
Forest ..................... 3000
Campaign ............ 1200
Urban environment ........... 200
housing /
office / workshop ......... 20
Vehicle ................... 14

The greater the number of negative ions, the healthier the air breathed.

Important: OR'IONS air ionizers are the only ones certified by the GENEVA Ecotoxicology Laboratory, which does not release ozone or nitrogen dioxide. Exclusive OPTEL plasma over-containment system. Certificate provided upon purchase. Ozone and nitrogen dioxide are two aggressive gases for the respiratory tract.
Or'ion ionizers strengthen the immune system through restful sleep and better organ oxygenation.

Ionizers Volume treated Price €
MV4 .......... car ........... 270,00
NP90 ......... 35 m2 ............ 375,00
TP95 ......... 35 m2 ............ 475,00
LB180 ....... 70 m2 ............ 715,00
R24 ......... 200m3 ............. 715,00

Thank you, but this is a manufacturer's advertisement

official report? medical tests?

it seems difficult to guarantee ions but no ozone
but just ask GENEVA's Ecotoxicology Laboratory:

- how they do it
- what is the quantity of ozone measured at least on the device mentioned

I'm looking for information and especially scientific studies on air ionizers.

Because I'm not a fan of pollen, it's not my period : Cheesy:

So I still hesitate between an ionizer and a "classic" air purifier, I saw an ionizer model that I like, the price I like less :? it's the lightair, it has it efficient and there are no filters ...

It's super difficult to find sites with scientific studies to prove the effectiveness of ionizers that are not in English, but I found this:

"The corporation of practitioners in alternative medicine in Quebec also wrote an article on the benefits of negative ions.
Here is their conclusion: “To be effective against allergens, studies have shown that it is necessary to use a device equipped with a HEPA (High Efficiency for Airborne Particles) filter, made with fiberglass. This type of absolute filter has a filtration capacity of 99,97% of particles of 0,3 µm. "
Source of copy and paste: site on air ionizer

So here it is, it doesn't help me too much if we say that HEPA filters are good and useful! Hepa filters are present in vacuum cleaners for information!

But I am looking for an ionizer without filters :|

If you have feedback, thank you in advance !!!

The problem with ionizers is the creation of ozone

I advise you rather to install a fountain / waterfall in your home

otherwise, a double flow ventilation box with gravimetric filtration already does the job well

Thank you for this list of places with a high concentration of negative ions!

I found air ionizers like the LightAir for example which are without generation of negative ions, on their official site it is shown that the generation of ozone is so weak that it cannot be measured and therefore that it is considered as non-existent!

So I think many models generate ozone but not the new ones

But hey the price is not the same as an ionizer in the form of usb stick : Lol:

But it is a good idea the water fountain, but difficult in an apartment! I write it down for later
