Don't print directions on the box; include a set inside the box.
I received my filter but the directions were on the outside of the box, covered with shipping labels that would not come off. I still do not know how to reset the machine so it knows the filter has been changed. Add instructions inside the box.

Thank you for the feedback and for choosing the Blue Pure 311i Max Smokeblock Filter. We are sorry the instructions were obscured by the shipping label. That experience should be easier. To reset the filter light, press and hold the fan button for about 15 seconds until the red light turns off. We have also shared your packaging feedback internally. If you have any further questions, please don't hesitate to our support team. We'll be happy to help!

Stopped sensing air quality
This machine was great, it turned on every time we were cooking. It would even turn on across the room if we opened up our powdered vitamins. Ever since I replaced the air filter, the machine now states air quality is “excellent” all the time. It doesn’t even turn on when the room is full of smoke from cooking.

Thanks for sharing this feedback. It’s great to hear the Blue Pure 311i Max was previously responding so well to changes in your air. This behavior can be related to the air quality sensor itself needing cleaning. We’ve reached out to you directly to help walk through a few steps and get your purifier responding as expected again.

Effectiveness
We purchased the Blue Air unit. It has met all expectations even used in normal conditions. It was time to replace the filter and, since we have forest fires this time of year, we ordered the smoke block filter and it has worked perfectly.
