It ended up breaking my purifier!

since owning an older blueair square metal purifier and using the smokeblock filter with that one and being impressed with its performance , i bought TWO smokeblock filters for my 411i a max purifier. i was shocked when not even two weeks later my fan is making a weird scratch noise, then not even a day later the whole unit shuts off like it has a short in it! My guess is that the filter put too much strain on the motor and put my unit to bed early.
Im hoping to get in touch with customer service to see about fixing this but im uncertain ill get a replacement as my 411i was a gift from my family back in april. and i dont have the reciept for it.
otherwise i hope to still use blueair products.

Unsure if it's working
Before replacing the filter the device became red regardless of ventilation or any other identifiable factor. Same with new filter. Not sure what's going on.

Thank you for your feedback on the Blue Pure 411i Max Smokeblock Filter. If the red light is the filter indicator, it may just need a manual reset by holding the fan speed button for about 15 seconds until the lights flash. If it’s the air quality light staying red, something else may be affecting readings. We’re here to help, so please reach out to our support team for further assistance.

Filter is a bit large
We made it work, but won’t be replacing with a new one when needed.
