How we write
Sources before opinions
Air-quality claims are cited to published work — WHO guidelines, EPA guidance, AHAM's CADR method — never to our own marketing.
Who writes it
The team that builds the devices
The guides are written and edited by the team behind Klarta air purifiers and humidifiers.
What we will not say
No medical claims
Klarta devices are not medical devices and are not intended to diagnose, treat, cure or prevent any disease. Where filtration is only part of the answer, the article says so.
