There are two ways to mount a device to the wall:
For temporary installations, you can use the included double-sided tape.
For permanent installations, we recommend using screws for wall-mount
Before installing, you should always assess if the included 3M command strip is sufficient, or if the wall or placement of the product requires screws for secure mounting.
3M command strip

How to apply
Clean the surface with rubbing alcohol. Do not use household cleaners.
Remove the red liners, and press strips firmly onto the back of the device.
Remove the black liner, and press the device to the wall for 30 seconds.
How to remove
Remove the device from the backplate, and twist the backplate carefully sideways until it loosens. Never pull towards you, as this may leave sticky adhesive on the wall.
Specifications of the 3M command strips
Good for humid environments: NO
Material: Foam
Weight capacity: 1 pound (0.45kg)

NB! There are stronger adhesives available on the market, that will provide a much more robust attachment, although they may not provide as easy removal. As mentioned in the business manual; Airthings does not take responsibility for improperly installed devices.
Screws
For permanent installations, we recommend using screws to wall-mount. Use flat-top screws (the backplate hole is 4 mm) where the length and plug type is highly dependent on the wall material.
