Purriko is another surprisingly good air purifier. It worked as well as the best purifiers we tested and it’s much more affordable—only about a third the price.
It’s not as gorgeous as the BioTrue, but it does look nicer than the average air purifier. It comes with a string you can use to attach it to a bag or keychain, making it easy to carry around with you.

Purriko uses a photocatalytic technology called Purrikomil—it’s said to decompose harmful gases into water molecules. When we tested it, we found that it worked just as well as the air purifiers that cost three times as much.
However, we found some issues with design: first, its odor-removing material isn’t very thick, so this purifier won’t last as long. (The company claims it lasts for 10 years.) Second, we had some difficulty getting all of the air purifier’s metal bits to stick to the adhesive on its backside. Once we got everything in place, however, we were glad to have that trouble.
