Dyson HP07 vs HP09 comparison: Are both really worth it?

Dyson HP07 vs HP09: Which one should I invest my money on? The old model (HP07) or the newer model (HP09)?  This is one of the major requests from my active readers over the past few months after my review about the Dyson HP02 and HP04 pure hot cool system.

Well, I am a big fan of the Dyson brand so I wouldn’t want to dispute the fact that both units are good. Also to remind you that for years, Dyson have been building up their reputation as a reliable company offering excellent quality. They even manage to put out some great looking air purifiers. That said, I was surprised at how hard it is to choose which model to buy between the HP09 and HP07.

Even though both models are from the same lineup (HP series) and look identical, they differ significantly from each other. One thing that stood out to me is the performance of the HP09. It seems to suck less power into the machine, meaning it is more improved.

Anyway, no need for you to go about stressing yourself. Here in this article, I’ve made a thorough review of the Dyson HP07 and HP09. This includes the Difference and the Similarities between the Dyson models. Read on to learn more!

Whichever model you choose, you can be sure of the possibility of heating, cooling and purifying the air

Device Filtration

The HP09 and HP07 have two-way filtration that ensures that they can capture and destroy even small particles. They both have a HEPA and Active carbon filter. The HEPA filter is designed to capture small particulate substances while the Active carbon filter is designed to eliminate bad odors and glasses. In this case, the HP09 and Dyson HP07 filters are the same.

The HP07 and HP09 are identical when it comes to appearance. Although both have a tower structure and an oblong shape, the HP07 tends to be lightweight and shorter than the HP09. If you are looking to get one of these two models, i’ll recommend you go for the Dyson HP07 because of its ease of transportation and less pace requirement.

Frequently Asked Questions and Answers

What is the difference between HP07 and HP09?

The only difference is that the HP07 can not destroy formaldehyde, but the HP09 can do it. The HP07 is also not as heavy and tall as the HP09. Both devices are similar in terms of specs and functionality. However, looking at the price differences – it’s more expensive for the Dyson HP 09.

Does Dyson HP07 destroy formaldehyde?

No! The Dyson HP07 can not destroy formaldehyde because it does not have a formaldehyde sensor that can detect it. The HP07 only has a particulate sensor, gas sensor, and humidity and temperature sensor. If you need a unit that can destroy formaldehyde, you may need to go for the Dyson HP09 unit. Is the HP09 worth it?

Yes! If your main purpose of getting a unit is to capture and destroy formaldehyde, the HP09 would be worth the investment. Plus you can expect to have this device purifying the air, heating and the room.


Both Dyson HP09 and Dyson HP07 are great options to make your choice because they have the same functionality. Although the Dyson HP09 has a special formaldehyde sensor that will enable it to detect formaldehyde in the air, and therefore be able to purify it.

If you need a device that can destroy formaldehyde, you may want to opt for the HP09. Otherwise, I’ll recommend you opt for the HP07 because the Dyson HP07 is more affordable than the HP09 while still able to heat, cool and purify the air.
