In this Dyson TP07 vs TP09 review, we will compare two of the latest Dyson air purifiers that can help you clean your indoor air from PM 2.5 and other types of air pollution.
Both devices can be used not only for air purification but also as a fan. And from the outside, not much separates them aside from the color. So should you go for the Dyson Purifier Cool TP07 or invest in the Dyson Purifier Cool Formaldehyde TP09?
This side-by-side comparison will help you find out.

Comparison: Dyson TP07 vs TP09 – What are the Differences?
Coverage Area & Efficiency
The TP07 and TP09 are suitable for rooms with an area between 46 m² (500 ft²) and 74 m² (800 ft²). With an oscillation of up to 350 degrees combined with Dyson’s Air Multiplier technology, both devices are able to project purified air throughout the room.
They also come with a focused mode for more direct and focused airflow, a diffused mode for more broad airflow, and finally a backward mode which diverts the airflow through the back of the machine, basically disabling the fan function while still purifying the air.

Clean Air Delivery Rate
Removing up to 99.95% of particles and allergens including pollen, dust, and pet dander as small as 0.1 μm with a HEPA filter, a layer of activated carbon also removes odors and gases including VOCs. In addition to all that, the TP09 is capable of removing formaldehyde.
Both the TP07 and the TP09 are fully sealed to HEPA H13, thus making sure that the captured pollutants stay within the machine. Clean air is then projected throughout the room at a rate of 290 liters (77 gallons) per second for the TP07, while the TP09 reaches up to 390 liters (103 gallons).

Working Noise
Considering that the TP09 has a significantly higher airflow, it is impressive to see that the engineering team at Dyson still managed to slightly decrease the maximum noise level from around 62 decibels (dB) for the TP07 to around 60 dB for the TP09.
Both devices feature a night-time mode that restricts the speed to Level 4 out of 10. During the day, you can set the TP07 and the TP09 to automatic mode so it only runs as fast and therefore as loud as is needed to keep the indoor air quality at the desired level.

Sensors & Display
A particulate sensor, gas sensor, and humidity and temperature sensor provide the TP07 and the TP09 with the latest information regarding their surroundings and act as input for the automatic mode. An additional fourth sensor allows the TP09 to detect formaldehyde.
The sensors also make it possible for you to view real-time air quality reporting such as 24H AQI, PM 2.5, PM 10, VOCs, NO2, SO2, temperature, humidity, and filter life on the integrated LCD screen and via the Dyson Link app (see below).

Connectivity & Compatibility
Both TP07 and TP09 offer three ways to interact with them. First, there is a remote that allows you to turn the device on and off, change oscillation, speed levels, set a timer, and change the mode. Thanks to a magnet inside the remote, you can attach it to the top of the purifier.
Then there is the Dyson Link app, which not only lets you control your device from anywhere you want but also displays the current air quality and notifies you once your filter needs to be changed. Lastly, you can also interact with both air purifiers using voice control via Amazon Alexa, Apple Siri, or Google Home.

Conclusion: Dyson TP07 vs TP09 – Which is the Better Air Purifier?
Formaldehyde can originate from furniture and carpets, paint and varnishes, air fresheners and household cleaners, and various other sources. If some of these items can be found in your home, you might want to consider investing in the Dyson Purifier Cool Formaldehyde TP09.
Aside from that, however, the Dyson Purifier Cool TP07 is almost identical to its successor, including when it comes to important buying criteria for an air purifier such as the coverage area, noise level, or the ability to monitor and control the device through your smartphone.
