Most air purifiers spend their lives doing the same thing.
They sit in a corner, quietly pulling air through a filter while hoping the air in the room eventually finds its way to them.
The Dreame AirPursue™ PM20 starts from a different premise: what if the purifier came to you?

Not physically, of course. But through a combination of radar sensing, adaptive airflow, environmental monitoring, heating, cooling, and purification, the PM20 behaves less like a passive appliance and more like an active participant in the environment around it. It’s an interesting glimpse into where home wellness technology is heading—and why air quality is becoming part of the broader smart-home conversation.
Air That Knows Where You Are
The most intriguing feature is Dreame’s Enviro Detect™ Technology.
Using millimeter-wave radar, the PM20 can detect people entering a room, power on automatically, and direct airflow toward their location. As occupants move throughout the space, the purifier adjusts accordingly. It’s a subtle shift in thinking, but an important one.
For years, smart-home technology has focused on responding to presence. Lights do it. Thermostats do it. Security systems do it.
The PM20 applies the same philosophy to air.
The practical outcome is straightforward: cleaner air reaches people faster.
A Purifier, A Fan, A Heater—and Something In Between
The PM20’s hardware is equally ambitious.
Dreame’s Dualflow Modulation Technology projects airflow upward and forward simultaneously, creating circulation patterns that move throughout the room rather than concentrating around the purifier itself. According to the company, this results in up to 33% greater purification efficiency and more consistent air distribution across larger spaces.
The numbers are impressive.
Coverage reaches up to 100 square meters of uniform purification area, while the airflow system doubles as both a cooling circulator and a space heater. During colder months, the heating system can begin producing warm airflow in approximately three seconds. During warmer months, it functions as an intelligent circulation system designed to keep air moving throughout the home.
That’s part of what makes the PM20 interesting. It doesn’t occupy a single category.
It’s a purifier.
It’s climate management.
It’s environmental monitoring.
It’s a smart-home sensor network wrapped inside an appliance.
Data, Everywhere
There’s a growing segment of consumers who want visibility into what’s happening inside their homes.

The PM20 was clearly designed with those users in mind.
Seven integrated sensors continuously track:
- PM1
- PM2.5
- PM10
- Formaldehyde
- TVOCs
- Temperature
- Humidity
The information appears on a large LCD display and can also be viewed through the Dreame app. Rather than presenting a generic “air quality score,” the system offers a detailed picture of environmental conditions in real time.
For homeowners concerned about allergens, indoor pollutants, volatile organic compounds, or seasonal air quality issues, that level of visibility can be surprisingly useful.
Built Around Cleaner Air
Behind the sensors sits a substantial purification engine.
The PM20 uses a 4-layer filtration system capable of removing up to 99.99% of airborne pollutants, while targeting odors, allergens, formaldehyde, bacteria, and viruses. Dreame states the system addresses 14 categories of pollutants and 9 types of bacteria and viruses, creating a cleaner indoor environment for households with children, pets, allergy sufferers, and anyone spending long hours indoors.
Additional features include:
- Auto Mode
- Comfort Mode
- Pet Mode
- App Control
- Voice Control
- Hidden Mobility Wheels
- Quiet operation down to 32 dB(A)
Taken together, it feels less like a collection of features and more like a platform for managing indoor comfort.
