All Plantower laser counters are pretested in PurpleAir facilities.
Replacement laser counters are intended for when a sensor’s previous laser counters fail and cannot be repaired. Make sure to select the appropriate laser counters for your device below, as each type features unique mounting and connection methods.
We appreciated the help identifying the problem with our Purple Air sensor. The delivery of the replacement part was quick. The video explaining how to replace the part was easy to follow. Up and running again. Much appreciated!

Fixed my sensor
My PurpleAir Classic Plus sensor went haywire after several years of reliable service, reporting really high numbers completely out of sync with other nearby sensors. I suspected the laser counters were bad, so I ordered a new set. Installation (following the helpful video) was actually very easy. Fixed my sensor and it’s back in service.

Replacement counter
I needed to replace the laser counter in my flex sensor. Deep cleaning the old counter did not fix the problem.
Ordering was easy, shipment was prompt and installation took maybe 10 minutes.
It was great seeing my sensor again showing 100%

Good product
Installed the new laser counters and they are working fine. Installation was not difficult but the instruction video I found on YouTube was just okay. I would have appreciated a repair video link being included with the counters, preferably with a barcode.
