    Satisfied

    Seems to work great, although the directions on how to "reset" so that the red light were wrong. Kudos to a person on YouTube for extra solutions.

    Works well

    Trying to sleep with a dust allergy is well...trying. The Max Allergenblock filter in my Blueair running in my bedroom is helping a lot.

    The filter subscription program is broken.

    I had signed up for the automatic filter “subscription”. I received Blue Pure emails that delivery was on its way. But the actual delivery app I was linked to for tracking did not register the delivery as existing. The manufacturer’s website and the fulfilment website do not sync. I kept getting conflicting results. The manufacturer’s phantom delivery tracking via email notices versus the empty delivery fulfilment company information. So then I had to dig down to ensure I had not been charged. After weeks of frustration and waiting , I cancelled the filter renewal subscription and simply ordered anew from the manufacturer at full cost (versus the promised discount from the subscription). Not an assure my experience.

    Wonderful for mild dust allergies

    I have had my BlueAir since two years ago because as a foreigner living in a wooden-built house I suffered a lot of sneezing and skin rashes and read that air purifiers can be helpful. This one has done wonders for me. Thanks to this filter both my cat and I breathe very well in my apartment, with so much less sneezing per week.
