It turns out that some of automobile air purifiers that are currently on market lack performance as they are not very effective in purifying air.
Consumers Korea showed its results of CADR (Clean Air Delivery Rate), removal rate of harmful gas, and amount of ozone occurrence on 9 automobile air purifier brands.
These brands include Philips’ ‘GoPure GP7101’, 3M’s ‘3M Vehicle Air Purifier Plus’, ABL Korea’s ‘ABSL PureZone AIR-90’, TechData’s ‘ForLG Air Circle’, Bullsone’s ‘Bullsone Air Therapy Multi Action’, Inavi’s ‘Aromi Air ISP-C1’, Airvita’s ‘Carvita CAV-5S’, CrystalCloud’s ‘Crystal Cloud Car Air Purifier’, and Alpine’s ‘Automate’.

After comparing their CADRs, products from Inavi, Airvita, CrystalCloud, and Alpine showed less than 0.1m3/min and thus showing not much effect in purifying air. Out of 5 products that displayed their CADRs, actual CADRs of products from Philips, ABL Korea, and TechData fell short of displayed CADRs.
After comparing their abilities to remove bad smell and VOCs (Volatile Organic Compound), it was shown that 7 products excluding ones from 3M and Philips showed not much effect in removing harmful gases.
Anionic air purifiers from Airvita, Alpine, and CrystalCloud have shown to create ozone and they require special attention from consumers when using them in a closed space such as cars.
“Even if ozone level is below standard level, ozone has tendency to accumulate in a closed space and it can cause harmful effect on one’s health when a person is exposed to it for long period of time.” said a representative for Consumers Korea. “These products require warning signs on them for proactive management and consumer safety purposes.”
