Thanks for posting. To those buying, beware: BlueAir air purifiers have something called an "ionizer", which has been shown in multiple peer-reviewed studies to cause hazardous health effects.

If you're buying an air purifier, I recommend a Levoit or other non-ionizing air purifier brand.

Posting this because I'd want to be informed if I didn't otherwise know.

Can you mention which peer-reviewed studies?

There are literally hundreds of studies on ozone. Here's one for example

Ionizer does not mean ozone creator, but here is one of those peer reviewed studies. Always have to consider what they are studying vs what you are buying. https://phys.org/news/2021-03-unc...fiers.html (A link to the journal article is at the bottom of this summary article - http://dx.doi.org/10.1016/j.buildenv.2021.107750)

This is generally a misinformed comment. While all BlueAir filters do charge the air, they emit 5 parts per billion or less and are even certified in California.

The background level of ozone indoors is 4-6ppb, only 25% or so of the average outdoor value of 20-45ppb.

If you're buying an air purifier, maybe you should just MOVE instead?
Yes, because if I move my dog will suddenly stop farting.

They work fine once you understand they aren't buttons at all but capacitive touch controls.

Don't have them all, here are a few:
~~~Air purifier ionizers cause direct adverse effect on Heart Rate Variability (HRV) in children:
1. Different cardiorespiratory effects of indoor air pollution intervention with ionization air purifier: Findings from a randomized, double-blind crossover study among school children in Beijing (2019)
https://pubmed.ncbi.nlm.nih.gov/31473392/
2. Metabolic linkages between indoor negative air ions, particulate matter and cardiorespiratory function: A randomized, double-blind crossover study among children (2020)
https://www.sciencedirect.com/sci...2019341169
~~~Air purifier ionizers can produce formaldehyde and toxic ozone gas that scars lung tissue:
Evaluating a commercially available in-duct bipolar ionization device for pollutant removal and potential byproduct formation (2021)
https://www.sciencedirect.com/sci...232100158X
~~~Air purifier ionizers increase biomarker for systemic oxidative stress, which causes cell and tissue damage and is major precursor of cardiovascular disease/heart failure/atherosclerosis:
Negative ions offset cardiorespiratory benefits of PM2.5 reduction from residential use of negative ion air purifiers (2021)
https://pubmed.ncbi.nlm.nih.gov/32757287/
~~~Air purifier ionizers generate Secondary Organic Aerosols (SOAs) and VOCs. SOAs penetrate deep into lungs/bloodstream, exacerbating asthma and cardiopulmonary disease:
Formation of Oxidized Gases and Secondary Organic Aerosol from a Commercial Oxidant-Generating Electronic Air Cleaner (2021)
https://pubs.acs.org/doi/10.1021/...tt.1c00416

The EPA warns of health hazards related to ionizing air purifiers on their website:
