Blueair Air Purifiers – Are They Worth It?
And Use Ionizers.
We tested for ozone next to the ionizer in a Blueair purifier and found that it produced 181 parts per billion (.182 PPM) of ozone, exceeding the California Air Resource Board limit of 50 parts per billion. The test was done right next to the ionizer, whereas the certification conducts tests away from the purifier.
Blueair air purifiers such as the Blueair Blue Pure 211 and 411 models are some of the most popular air purifiers on the market. Yet there is confusion about whether Blueair air purifiers use ionizers and produce ozone.
In some sections of their website, Blueair avoids answering the question directly, instead saying that “Blueair air purifiers use a combination of mechanical and electrostatic filtration.”
What Make’s Smart Air Different?
University of Chicago Professor Thomas Talhelm started Smart Air as a not-for-profit B-corp because of how shady the air purifier industry is. Smart Air provides extremely effective (and beautiful!) HEPA air purifiers with no dangerous gimmicks at an incredible deal.
And Use Ionizers.
The Illinois Institute of Technology found that this ionizer function increases negative ion concentrations over 10 times! These negative ions can potentially react with the air to produce dangerous VOCs – something their HEPA filter doesn’t capture.
Pollutant removal efficacy testing involved measuring the CADR for each air cleaner using a pollutant injection and decay method (Offermann et al., 1985; MacIntosh et al., 2008; US EPA, 2018). The CADR is a measure of how much pollutant-free air an air cleaner provides, reported in units of airflow rate (e.g., cubic feet per minute, or cfm). The CADR is traditionally measured for particulate matter but can also be measured for other types of airborne pollutants (Howard-Reed et al., 2008).
Why Ionizers?
It’s quite simple. Adding an ionizer is an extremely cheap way for an air purifier company to increase its purifier’s CADR (measure of performance). Additionally, consumers are typically unaware of the negative effects of ionizers (or the fact they are in the purifiers at all).
