The fan in my SDS011 became very noisy due to collected dust putting the blades out of balance. . I removed the fan and and cleaned it. Now the SDS011 reads low. I assume the fan has slowed thanks to my efforts. Does anyone have a source for a replacement fan? Any other ideas would be welcome. I did find a few of the fans on ebay but at a cost near that of the whole unit.
Okay, so housekeeping is not my thing.
