How does this model differ from the Blue Pure 411?

Key upgrades include: more coverage, quieter on highest fan, & smaller compact size.

I've replaced my filters, now how do I reset the filter replacement indicator?​

Press and hold down the LED button for 10 seconds to reset the replacement filter indicator. ​​

Why is my LED yellow?

The LED indicator will turn yellow after 5 months of operation to warn that it's almost time to change the filter. When the indicator light turns red (one month later), it’s time to change the main filter.
