For an NR08M that makes no mist, Miro's own troubleshooting separates mist formation from fan delivery. Start with enough water for the floating engine, correct engine installation, a clean undamaged vibrator, the genuine adapter, and the normal floating depth. If the engine forms mist but the fan or funnel does not deliver it upward, move to those separate branches instead of replacing parts immediately.
If you can see fog being created inside an NR08M but little or none reaches the room, Miro specifically points to the inner funnel and the fan path. The inner funnel is not decorative: without it, mist can remain inside the humidifier. Verify the funnel and engine assembly first; if mist is clearly forming but the fan does not spin, follow the fan-specific path.
When an NR08M's vibrator is making mist but the fan is not moving it upward, the problem is narrower than a general no-mist complaint. Miro recommends checking engine installation first. After a long period of non-use, its support article also describes soaking the engine in lukewarm water for about 30 minutes, manually freeing the fan while the engine is unpowered, then reinstalling it for a retest.
