Dyson Purifier Humidify+Cool PH2

Yes. The PH2 De-NOx features a catalytic filter that continuously traps and breaks down formaldehyde molecules into water and CO2, so you do not need to replace the filter as often as you would with standard carbon filters.

The device uses Ultraviolet Cleanse technology to expose every drop of water to a powerful UV light, which eliminates 99.9% of bacteria before the water is released into your room as mist.

It is important to note that this is a purifier and fan, not an air conditioner. While it uses Air Multiplier technology to project a powerful, cooling stream of purified air, it does not lower the ambient temperature of a room like a refrigerant-based AC unit.

Filter life depends on your local air quality and usage, but generally, the HEPA H13 filter should be replaced once every 12 months based on typical daily use. The MyDyson app will track your filter life and send you a notification when it is time for a change.

You have full control. You can set a target humidity level through the MyDyson app or the remote, and the machine will automatically adjust its output to maintain that level, or you can switch it to manual mode to adjust the fan speed and mist intensity yourself.

Yes, it features a dedicated Night mode that monitors and purifies using the quietest settings and dims the display lights. While it is not silent, it is designed to operate at a lower noise level to minimize disruption.
