FAQ

What is the warranty for Blue Signature™?

Register your product to extend the 1-year warranty to a 3-year warranty.

How often do I need to change the filter?

You filter will last up to 1 year thanks to our unique patent-pending design & proprietary RealTrack algorithm that accurately calculates the remaining filter lifetime based on fan speed, usage time, and pollution levels.

When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you. Alternatively, connect to the Blueair app to receive an alert and easily re-order at the touch of a button.

What are the noise levels?

Blue Signature™ operates quieter than a whisper on low at 23 dB and is no louder than 55 dB on high fan speed.

What room size is best?

To achieve maximum performance we recommend placing your unit in a room around 705 ft² so your air purifier can clear the air at the AHAM recommendation of 4 times every 12.5 minutes. The Blue Signature™ will clean up to 3,385 ft² in 1 hour.
