Fast replacement (under warranty)

New counters work fine, hopefully will last longer than my previous set (replaced original after several years), which lasted ~300 days... thanks!

Excellent support

One of my counters was giving very high readings. After I tried the suggested cleaning routines, Purple Air offered to send replacement counters. I installed the new counters and now my unit is working properly. Great service.

I failed at installing a replacement laser counter

I did try to follow the instructions very carefully, but, nonetheless, my Purple Air is now dead. I had a lot of trouble transferring the old chip to the new laser counter. Oh well, it was fun having the device for a couple of years.

Laser may be fine but my unit still doesn't work

I am glad there is an option to replace the laser. It did not work for me and have tried several troubleshooting ideas. I wish I could just get a new unit but it is not in the budget at this time. Hoping others have better luck.

Hi Andrea,

We're sorry you've had a hard time replacing the laser counters in your device. We'd be happy to help if you send an email to contact@purpleair.com!
