Your Particle + Carbon 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.
The humidification wick filter should be replaced every 6 months. It should be cleaned weekly when in use according to the instructions in the user manual to maintain optimal performance.
To clean the wick filter, rinse with water weekly, or for a deep clean, soak in citric acid and rinse. Use 20g of citric acid for every 1L of water for 1 hour. Rinse well under running tap water.
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 1,728 ft² in 1 hour.
Humidity sensors can vary depending on where they’re placed. For best results, keep them away from windows, vents, and right next to the humidifier—and give them time to settle.
Not at all. In super-dry air, even a small bump (like 5–10%) means your humidifier is doing its job. The air is soaking up moisture as fast as it’s added.
It does exactly what it should
We live in a very dry environment during the winter with the atmospheric humidity dropping considerably indoors. This device makes humidifying the air very easy. It uses an amazing amount of water over the course of the day. The air filtration is a bonus - we already have 2 Blue air filters. One member of the household has COPD so maintaining air quality is very important.
The wireless app is a neat feature too. My only criticism is the lack of a washable pre-filter to extend the life of the main filters.
THis unit is awesome. I highly recommend it. It may be large but it does such an amazing job. and it is nice and quiet too.
Had some issues, but they took care of them in a timely matter, sent another unit and working fine, they had a problem with auto mode, clean air but no humidity but that's working now.
The 2 in 1 Pro is a great humidifier. The app is very friendly and it’s very easy to customize how you want the unit to work. This is the only humidifier I have ever used that got my large spaces up to a comfortable humidity with very little noise and no drafts. The lowest setting is whisper quiet. The large filters last a long time and there is very little maintenance needed. It has converted me from only using a steam humidifier.
I haven’t used it yet as an air purifier. I am looking forward to trying it as the weather gets warmer and the pollen and dust starts to invade our house.
Fabulous!
