Dreame AirPursue PM20: two-minute review
The Dreame AirPursue PM20 is an air purifier with a whole load of tricks up its sleeve. The USP is the ‘Follow’ mode, whereby the large, cup-shaped head will swivel to follow you wherever you go in a room, blasting purified air in your direction. In practice, it’s very impressive to watch. There’s also ‘AI Purify’ – an Auto mode by another name – whereby the AirPursue will monitor for five specific pollutants and adjust settings to clear them when they’re detected.
Aside from these and two more special modes, and a variety of manual control options, the appliance can also heat or cool the air as required. So it’s positioned to rival not only the best air purifiers on the market, but the best fans, too. Not bad for the brand’s first ever purifier.
When it comes to air purifiers, I’m often left wondering how I’m meant to know if they’re actually doing anything. Not so with the AirPursue PM20, which offers real time pollutant readings within the Dreame companion app, so you can watch at any moment as it cleans the air in your living room or bedroom. It’s able to sense and remove 14 different pollutants (although that doesn’t include CO2), and gives each one a rating so you can tell how good or bad the air quality is.
All that functionality comes at a bit of a price, and replacement filters aren’t especially cheap either (deals are appearing already, and I think it’s decent value for what you’re getting). While the design is sleek and modern, there’s no getting around the fact it’s really rather large, although Dreame has helpfully added wheels to make it easy to maneuver from one room to another,
The PM20 is geared towards use in medium or large rooms, with a CADR to match (400 m³/h). If you have a smaller space you’d be better off with the PM10 sister model, which has a has a CADR of 300 m³/h.
Keep reading to see how well the Dreame AirPursue PM20 cleaned the air in my historic home and gave me more peace of mind.
Dreame AirPursue PM20 review: price & availability
- List price: US$999.99
- Launch date: June 2025
- Availability: US and Canada
The AirPursue PM20 is Dreame’s first ever air purifier, and launched in June 2025. It’s available to buy direct from Dreame or via Amazon in the US and Canada, with a list price of $999.99. (The smaller AirPursue PM10 costs $899.99 at list price.)
You can take that list price with a pinch of salt, because at time of writing this review the PM20 had only been out a month and was already attracting significant discounts on Amazon (it dropped to $769.99 during the Prime Day Sale). Even with that discount it’s still a premium purchase, though.
The only additional cost associated with this air purifier are the replacements for the carbon filter and the high efficiency composite filter, which are $59.99 and $99.99 respectively. They have to be replaced between 6 and 24 months, depending on how hard they’re put to work.
Considering that this air purifier has multiple modes, speeds, heating capabilities, app and voice integration, and AI settings, I’d say the price tag is reasonable. In fact, I’ve seen more expensive air purifiers that have fewer features. However, it’s still a decent investment, so if you’re on a tighter budget there are plenty more affordable options about.

Dreame AirPursue PM20 review: design
- Large air purifier that can also operate as a fan or heater
- Smart capabilities, AI detection, and app integration
- Provides specific information about pollutant levels
The Dreame AirPursue PM20 arrived assembled, allowing me to plug it in and immediately start purifying the air within my home. The only setup required of me was connecting the air purifier to the Dreame app and tap a button in the app to authorize the voice command function.
In terms of appearance, the Dreame AirPursue PM20 reminds me of a mini R2-D2, with its bulbous head, cylindrical body, and the wheels placed on the bottom. I was so glad for the wheels as I could move the air purifier around the house without having to pick it up – as I may have mentioned, it’s not small. In the air purifier world, it also bears a striking resemblance to the Dyson Big+Quiet.
The head has a small, square LCD screen that displays air pollution levels via colored graphs. Buttons on the head allow you to turn the purifier on and off and cycle through information on the LCD screen like air pollutant, temperature, and humidity readings, and the filter life.
Inside, the PM20 is outfitted with two filters. First, a high efficiency composite filter (HEPA-13 grade) which removes indoor pollen, dust mites, haze, bacteria, viruses, and other fine materials, and which must be replaced every 16-24 months (the app notifies you). Second, a carbon filter, which is used to remove indoor kitchen fumes, pet odor, TVOC, formaldehyde and other harmful gases. The replacement time for the carbon filter is every 6-12 months.
There more going on with this air purifier’s design that can’t be seen. It’s outfitted with dual-flow modulation technology, which means the air flows in and out of the head and the body. It can apparently project air forward up to 10 meters.
The airflow fan speed can be adjusted between 1 and 10 and the wind direction can be set on 45, 90, or 180 degrees. You can also utilize various special modes:
- AI follow – directs pure air at whoever is in the room
- AI purify / Auto – monitors for 5 pollutants and switches on when detected
- Pet purify – enhanced airflow specifically geared towards pet hair and odors
- Comfort – quiet, long-range air projection
- Cooling
- Heating – set between 78 and 104 degrees Fahrenheit
The most exciting of those is AI follow, where the purifier head will follow you as you move within a room. If there is more than one person in the room, the purifier will toggle between the two people’s positions.
Because I tested the AirPursue in the summer, I usually used the Cooling mode, but I was also pleased to learn it would earn its space in winter by doubling up as a heater. I found Comfort mode was a great option when sleeping at night because it lowered the fan speed so the noise wasn’t bothersome.
Speaking of which, noise-wise, the air purifier is not that loud. On the lowest fan speed, it has a dB rating of 54. I measured the highest speed at 67 dB.
With the remote, you can adjust the direction of the fan, change the fan speed, turn on the heating function, and choose between the different modes. I preferred managing the settings in the app or with voice commands.
Dreame AirPursue PM20 review: performance
- Detects and clears pollutants quickly
- Can cool or heats spaces while purifying them
- App makes it easy to control purifier and monitor pollutants
My house was built over 100 years ago, and as a historic building it produces a lot of dust and allergens. Not to mention, it was probably updated at various times when pollutants weren’t necessarily monitored or regulated. As someone who has asthma and allergies, I’m always looking for ways to make my home – where I work, sleep, and live – healthier. After testing the Dreame AirPursue PM20, I feel a lot more confident and comfortable breathing in my own house.
To speak plainly, I love the Dreame AirPursue PM20. It was easy to move it between rooms with the wheels. Once I connected it to the app, I dove in. I was glad to discover that the air quality of my house is better than I thought. I gleaned this information from the overall air quality score. However, thanks to the Dreame sensors, I was able to see the exact levels of harmful pollutants – PM1, PM2.5, PM10, HCHO, and TVOC – present in my home.
I didn’t know what these pollutants meant, but the app provided definitions of each one. For instance, I learned that HCHO is a “common indoor pollutant, the release period of formaldehyde from furniture, paint, and adhesives lasting for years”. Not only that, but the Dreame app tracked the pollutant reading and provided a value range for each pollutant, and then labelled the reading as either excellent, good, moderate, or poor. I was able to track the pollutant readings at any moment and even by days and weeks within the app.
To see how well the Dreame AirPursue PM20 detects pollutants and clears them, I ran a test with dry shampoo. I began by screenshotting the readings (prior to spraying the dry shampoo) to gain an air quality baseline. Then I sprayed dry shampoo about two feet in front of the air purifier. Within the app, I saw the air purifier recognize the pollutants from the dry shampoo within about 10 seconds.
From there, I monitored the air purifier, noting the initial increase in pollutant readings. The purifier cleaned the room within about 11 minutes. The TVOC reading was the only pollutant that didn’t quite reach the original reading after 11 minutes (it was 2 points higher). In fact, the TVOC reading fluctuated over the next few hours within one to two points of the original reading. At least it remained well within the ‘excellent’ air quality range.
Most of the time, I set the Dreame AirPursue PM20 on a fan speed of 10, and the wind direction at 180 degrees. Sometimes, I used the AI Follow feature which means the head of the purifier followed me around the room, literally purifying the air around me. This feature was cool to see in action, and reliably well on test.
I don’t have pets, so I didn’t need the Pet Purify mode, but I know that it could be helpful for those who do share their home with four-legged friends, especially in removing odors (the purifier cleared kitchen odors within my house in minutes). The Comfort mode was great to use at night; it was quieter than my ceiling fan.
Like a few Dyson fans, the Dreame AirPursue can also be used as a fan or heater. Because I was testing in Texas in July, I mostly used the Cooling more, but the Heating option will be ultra-helpful in winter (it lets you adjust the temperature between 78 and 104 degrees Fahrenheit. The 12-hour timer was nice, but for the most part, I turned the purifier on and off at my own will.
I didn’t have any issues with this air purifier. The only thing to keep in mind is that when the fan speed is set to 10 (or the highest speed), you must raise your voice and move near the air purifier to use the voice command. That wasn’t a big deal to me, because I usually used the app on my phone to adjust the settings as I always forgot the voice commands and would have to look them up in the app anyways (helpfully, Dreame lists the voice commands here for reference).
Overall, I think the Dreame AirPursue PM20 does what it says it will do and brought me a lot more peace of mind. I feel better knowing that I’m breathing cleaner air in my home day or night.

How I tested the Dreame AirPursue PM20
I used the Dreame AirPursue PM20 for a few weeks in July in my 105-year-old home in Texas. I used the purifier in various rooms to get a variety of readings, as well as testing each of the windspeed settings and special modes. To get a more objective view of how efficiently it cleared air, I also sprayed dry shampoo a few feet from the purifier to see how quickly the purifier detected it and cleared it from the room.
