Made a Huge Difference

Within a day I noticed a huge difference. It’s done a fantastic job filtering out the allergens and pet/old house smell I had been living with.
I would recommend this to a friend!

Not the same as the Medium

Just received the Blue Signature Large, to go along with the Medium I have. For some unknown reason Blueair did not include a display sensor for TVOC's like on the Medium model. So one does not know the level of VOC's or if the pruifier reacts to smells. I will see how it does removing ordors, probably not as effective as the medium model. More than likely this will be returned. Why this desirable feature was deleted from the more expensive model is not understandable. Pay more get less?
No, I would not recommend this to a friend.

Works great

We’ve been using the Blue SignatureTM Large humidifier in our 3-month-old daughter’s room, and it’s made a noticeable difference. The air feels more comfortable, especially at night, and it’s helped keep the room from getting too dry.It’s very easy to use—setup was simple, and the controls are straightforward. It runs quietly, which is perfect for a nursery and doesn’t disturb her sleep.Since using it, we’ve noticed the room feels more balanced and comfortable overall, which gives us peace of mind for our baby. Definitely a great addition for anyone with a young child or dealing with dry air.

Looks great, could use a SLIGHT improvement

Works as intended... it’s an air purifier. As an engineer I think that the injection molded plastic used for this system could be beefed up a little bit. For the cost that you pay, the cheap flimsy plastic that is on the top and base could be increased a couple mils to provide a sturdier and more luxurious feel. Do I like the product. Yes. Would I buy it again seeing it in person. No.
