Hello @Leo777 

We'd be happy to go over these differences with you.

The Dyson HP06 is our Pure Hot + Cool Cryptomic machine, which features an advanced 360º filtration system, which captures potentially harmful pollutants from the air. HEPA and activated carbon filters capture gases and 99.95% of pollutants. And, Dyson Cryptomic technology traps formaldehyde molecules, continuously destroying them with catalytic oxidization. With this machine you have 10 speeds of airflow, the ability to set a target temperature of up to 99 degrees Fahrenheit, ability to connect to the Dyson Link App via both Wi-Fi and Bluetooth, and also have backward airflow mode. 

The HP09 Pure Hot+Cool Formaldehyde is very similar in performance, however is a newer model. HP09 was re-engineered to delivery 50% cleaner air, and offers Dyson's most advanced filtration system, combining a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde. HP09 also features a fully sealed HEPA H13 filter- anything that goes inside of this machine is going to stay trapped there.
