Here is the huge issue that is never mentioned regarding Ionizers, most being sold today. Yes some ionizers trap particles on an ionization rod, which needs to be cleaned on a regular basis {more of a PIA than a filter} or the unit becomes less and less efficient. But most of the SCAM ionizers being sold out there today don't really collect anything. They charge the ions in the air and tout that the charged particles will "trap" the dust and pollen. Ooooh that sounds so good doesn't it.. But wait people, let's use our brains and think for a moment.. what happens to those "trapped" particles? They fall to the ground you say? I mean, they're not in the air anymore.. Right? So ok, now you have all these "trapped" particles falling to the ground, all over your house. Why do I say all over your house? Because there's no way to predict where a dust or pollen particle will collide with a negatively charged ion, and when that happens is when that dust or pollen particles will fall out of the air. So let me ask you this.. how often do you vacuum? Cause if you're not vacuuming every day and you're walking around your house or have pets or children, all they are doing is kicking those same particles back up into the air.. over and over. Sounds pretty stupid to me and a total waste of money, not only in purchasing the device but also in the constant use of electricity that accomplishes absolutely nothing. At least with an Air Filter you can pull the filter and see that stuff is actually being removed.

Pretty good explanation, theres almost too much information out there, I'd love to see actual tests, or just not have allergies

Thank you...very well organized presentation.

What about air purifiers with an ioniser built in them?

Thank you for the info, much appreciated!

Very useful video, thank you!

I use them together on my cleanings

I need both more ionizer though

so you only want to use an ionizer only if the air is very polluted. this is a good idea cause i have asthma i don’t want any respiratory problems . i just want no dust in my room.

I just bought one with a voucher,even though it came from China,there is a warranty card and certification mark,i also do some teardown,i found it legit because there is an ionizer module with a brush on it

The principle of action of the air ionizer is to saturate the air with negative oxygen ions. In turn, aeroions inhaled by a person give their electrical charges to blood erythrocytes, and with them - to the cells of the whole body, normalizing metabolic processes.

Should have mentioned noise levels as well. Air purifiers are noisy while ionizers are dead silent.

Which one would use to eliminate the smell of decomposed animals at home?

Wow, way too not compare anything. Give me some real world results for f*c$ sake. Run both in a similarly dusty room sample air before and after.

Les ioniseurs ne produisent pas systematiquement d'ozone.

Heres something wild: cant ijust use a vacuum with a thin cloth to filter dust lol
