    Just upgraded to the DualProtection filters

    The order and delivery process went well. Too soon to tell about the efficacy because these new, finer filters just arrived a few days ago, but so far they fit our devices easily and are working well.

    Thank you for sharing your detailed feedback. We apologize for any disappointment you've experienced with the design and performance of your humidifier. We understand that aesthetics and functionality are important, and we're sorry to hear that the unit did not meet your expectations in these areas. For the best performance, we recommend placing the Humidifier in a room up to 500 sq. ft, adjusting your preferred target humidity level and setting the humidifier to Auto mode. This allows the device to react to the changing humidity in your room and adjust to meet your target humidity. We appreciate your acknowledgment of its reliability and quiet operation. Your feedback is valuable to us, and we will use it to improve our products. If you have any further questions or need assistance, please don't hesitate to reach out. We're here to help!,Blueair,Blueair Team,clientresponse

    Excelent devices, highly recommendable.

    I have been using these filters 2 years ago, and you can feel the difference in the quality of the air surrounding you.

    I have 2 one in each room, the sensors tell you what's going on!

    There are very accurate.
