    Terrible S&H

    I’m sure this is another one of those companies that’s trying to reduce packaging material and consequently, their environmental footprint. That all sounds well and good.. They sent the filter in its product box, a very thin cardboard material with no taping on any of the seams, just as if someone pulled the box off of a shelf on a retail store and slapped a mailing label on it. The box was all banged up like people have been playing football with it and it caused dents and impressions on the accordion style filter material. Just put the darn thing in a reasonable sized cardboard box,

    shipping it to your customers in a safe, solid and secure manner..

    Love Blue Signature

    Easy to set up and use. After a week truly feel the difference in our home. Bonus, it’s beautifully designed serving as an end table in the living room.

    I’m having a lot of trouble with my purifier

    First, it will not let me connect to Wi-Fi. I moved homes and in my new house I just cannot connect. I’m doing everything the instructions say. Can you give me a number? I can call so I can speak to someone

    Does a great job!

    I bought the air purifier specifically to deal with smoke from Southern California brush fires. Fortunately, we have not had any fires locally since the purchase. But it does a good job if my husband overheats the olive oil while cooking.
