The bottom of the Hot+Cool has a similar perforated design to what we saw with the Dyson Pure Cool Link Tower I reviewed in May; this is where air, odors, and any loose particles floating around in the air are sucked in to be processed through the 360° Glass HEPA filter.

There are buttons on either side that can be pressed to remove the outer casing when it’s time to replace the filter or should you ever need to brush off something that’s causing a blockage.

I’m jumping ahead of myself just a bit but on the back of the fan, there is a plastic hatch which should only be opened when the filter is being replaced …

… inside the hatch, there is a black input that will need to be wiped down at the time you change the filter to help maintain sensor accuracy.

Once you’ve removed the Hot+Cool from the box and figured out where you’d like to place it, you’ll want to connect it to the Dyson Link app. This is a simple process of connecting it as a new device, selecting it from the list of Dyson connected products that will pop up, and then entering your home WiFi network information. Each Dyson Link product has its own WiFi password and MAC address.
