Questions about Dyson Hot+Cool Formaldehyde HP09

I leave mine on 12 hours a day. I changed the filter after 12 months.

With these extreme price fluctuations, the decisive factor is usually not the market price, but the internal change of the most favourable supplier, which changes our purchase price. Our system also updates the available sources of products on a daily basis.

yes

It acts as a fan, not as an air conditioner, so it doesn't really cool in that sense.

50W is without the heater at maximum fan speed (there are 10x speeds). With the heater it's 2000W of consumption.

It's really very far off the mark. Thank you for pointing this out, we have corrected the error.

No, you need a dehumidifier for this. Like this one, for example: Kibernetik M20 (50 m², 20 l/24h)

Yes, you can,

This Dyson Purifier Hot+Cool is a HP09 model.

I am sorry to inform you that the HP09 is not suitable for heating an entire 81m2 flat. This unit produces a warming airflow in the immediate vicinity, so it can be used mainly for smaller rooms. The heat function produces up to 2250 watts of power.
