Notes

A tower air purifier/fan is commonly run many hours per day, so the main wear items are the fan motor, internal power supply, and the filter system (including seals and housings). Filters are consumables and should not be treated as "repairs," but damaged filter doors, noisy bearings, or power issues can be.

Repair tends to make sense early in life when the motor is healthy and the problem is limited (sensor, filter latch, or a single electronic failure). Replacement becomes the safer bet when noise increases over time, the unit struggles to move air even with new filters, or electronics fail repeatedly.

Also consider replacement if parts are backordered or labor costs approach the threshold.
