While Comparing Dyson am09 vs pure hot and cool, we discovered the HP04 has some upgrades which are lacking in the AM09. Below a comparison between the Dyson AM09 vs HP04 would give you detailed information on their specifications. Which includes the difference and similarities in features.

Dyson Filters

When it comes to filters, both HP04 & AM09 certainly comes with filters. While The HP04 serves as a purifier, heater and fan with a sealed HEPA + Active Carbon air filtration system. Although the AM09 filter is not known yet as of the time of writing this review

The air filtration system in the HP04 allows for it to filter the air. Its HEPA + Carbon filters in the HP04 is responsible for the capturing of 99.97% microscopic particles that are 0.3 small in size and could easily evade most regular filters.

While the Active Carbon filter is responsible for containing bad odours, moistures, toxins, and Volatile Organic Compounds.

LCD Display

Talking about the display, the Dyson HP04 and AM09 comes with an LCD. The Air purifier Display is responsible for making the recording of airflow, temperature and all other data in real-time displayed. In turn, helps you to understand the condition and gives the possibility of controlling it. 

System Functions

The Dyson Pure Hot and cool serves 3 in 1 functions (Purifier, Heater & Cooler). However, the AM09 serves 2 in 1 functions (Cooler and Heater). The air purifier function is responsible for purifying the air contaminated free, Cooler to make the normalize the whether a make it cool during heat period, and the heating function which serves as a heater to warm the room up during winter season.

Going through these functions, we discovered that the HP04 serves more functionality compared to the AM09 which doesn’t support the purifier function. Although still perform the heater and cooler functions.

Fan Modes

Both systems offer a jet focus control and diffused mode. However, while the HP04 offers additional modes (Auto and Night modes), the AM09 doesn’t support the Auto modes and Night modes.  The Jet focus mode helps to dispense enough air in a certain position within the room for a long time, while the diffused mode is essential for the distribution of air widely across the room.

The night mode helps to automatically put the system on night function during the night to avoid distraction from sleeping at night, this is useful to avoid noise.

System Connectivity

While researching HP04 and AM09, I was discovered that while the Dyson HP04 offers smart connecting features and control functions such as WiFi connectivity, Dyson Link App for easy control of your purifier using a smartphone and Alexa control for easy voice control.

Sad to say, the AM09 does not support any of those Smart controls which makes life easy, except for the simple magnetic handy remote control which is all available in the HP04.

Based on our findings, we confirmed with Dyson company, and it was stated that they discontinued the AM09. (although, Dyson offers air purifiers, which could serve the sames purpose as that of the AM09). As an alternative, we recommend you go for the HP04 Purifying Heater + Fan.

Aside, the purifying function which makes it more advanced than the AM09, the HP04 also comes with smart control such as the Dyson Link App. Plus it’s WiFi-enabled & Alexa voice control compatible.

Lastly, the HP04 has a backward mode in addition to the auto & night mode, and the diffused and Jet focus mode. All these are also missing in the AM09 model.
