Unit completely rusted out, no warranty coverage

So I have purchased 3 of the PA-II models. One of them completely rusted / corroded out and stopped working. No warranty coverage. Had to just toss it and abandon the site. 35% failure rate is pitiful. Really disappointed with the quality of these units.

Hello,

We apologize that you've been experiencing this amount of trouble. If you would like, we're happy to assist in any way we can or talk about warrarnty coverage in an email to contact@purpleair.com.
