Register your product to extend the 1-year warranty to a 3-year warranty.
Your filters will last up to 6 months thanks to our 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.
To achieve maximum performance we recommend placing your 2-in-1 in a room around 360 ft² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes. The 2-in-1 will clean a 863 ft² space in 30 minutes, and 1,726 ft² in 1 hour.
