If you have any questions, please don't hesitate to contact us.
PurpleAir is committed to producing safe, reliable air quality sensors and we take any incident reports from our customers very seriously. As you may know, as of January 24, 2019, PurpleAir has received twenty-six reports in the United States of instances where the power supply model number RKPO-UL052000C emitted sparks or smoke. In response to these reports, PurpleAir is notifying all customers of a voluntary safety recall in which PurpleAir will replace power supply model number RKPO-UL052000C free of charge. This power supply model number was shipped with PA-II and PA-II-SD air quality sensors prior to August 3, 2018.
We understand that some customers purchased multiple air sensors and distributed them to volunteers and participants in air monitoring initiatives. We do not have contact information for those who received air sensors in this manner. If you or your organization distributed PA-II or PA-II-SD air sensors to others, we ask for your assistance to inform the recipients of the importance of replacing power supply model number RKPO-UL052000C. We ask that you send us the names and contact information of those who received a PA-II or PA-II-SD air sensor through your organization and we will distribute this letter and power supply replacement information to everyone on your list. Or, if you prefer, you can let us know how many air sensors you distributed and you can forward this email to those recipients.
