    I can't tell if it made an air quality difference or not. I have a new home and just wanted to take precaution. It was the only product that stated it removed formaldehyde.

    This fan from Dyson is quite good. It has both afan and heating mode, allowing you to tweak the temperature in any area in which you might be located. Many features can be controlled using Google Assistant, allowing you to hands-off control this unit. I use G.A. through scheduled routines to remotely turn the Dyson on and off at specific times. It has a small display screen on the front that allows you to view the status of your filter, which granted I don't use a lot, but is handy because it will tell you how many particulates it has filtered or if the filter is at end-of-life. Based on our experience with this Dyson, it is worth every penny.

    The heat works pretty well on it but the air doesn’t cool down a room much. For the price you would assume that both would have a pretty significant impact. I haven’t noticed a difference in the purifying.

    Wow what a product. Able to take formaldehyde out of the air is the best feature. Not cheap though. Wifi linkage though is not really working and you need this to check product status.

    This is simply the best air purifier. If you want to know what's in your lungs, use this. If you're concerned about VOCs/formaldehyde/etc, and not just dust particles, this is the way to go.
