In an era where indoor air quality has become increasingly important for health and wellness, Dreame has launched its first-ever air purifier with a feature that sets it apart from the competition—intelligent radar-guided airflow that follows you around the room. The AirPursue PM20, introduced in June 2025, represents a bold entry into the premium air purification market with 3-in-1 functionality: purification, heating, and cooling.
What Makes the PM20 Unique?
The standout feature of the AirPursue PM20 is undoubtedly its AI-powered “Follow Mode.” Using millimeter-wave radar technology, the purifier detects your presence and position within a room, then automatically directs a stream of clean air toward you. This technology maintains coverage within a 5-meter range and can track multiple people simultaneously, adjusting the airflow to deliver balanced air coverage to everyone in the space. When you enter a room, the purifier powers on automatically—a convenience that reflects Dreame’s focus on smart, hands-free operation.
Performance and Purification Power
The PM20 boasts some seriously impressive specs. Its Clean Air Delivery Rate (CADR) hits 400 m³/h, and the Formaldehyde CADR is a solid 250 m³/h. To put that into perspective, it can purify a space of 1,883 square feet in a mere 15 minutes, or tackle up to 7,534 square feet in an hour. This purifier is built for rooms up to 100 square meters, roughly 1,076 square feet, making it a great choice for spacious areas.
Dreame’s own Dualflow Modulation Technology is at work here. This system employs both upward and forward-facing air outlets, which boosts efficiency by around 33%. The dual-outlet design pushes clean air up to 10 meters ahead, preventing the buildup of pollutants in those tricky spots like corners or behind furniture—a known issue with many other purifiers.
Comprehensive Filtration System
The PM20’s core functionality stems from its robust 4-layer filtration system, designed to eliminate 99.99% of detrimental pollutants.
Initially, the magnetic housing pre-filter effectively prevents the entry of debris, hair, and larger particles. Subsequently, the high-efficiency composite filter, incorporating H13-grade HEPA filtration, captures allergens and dust particles as minuscule as 0.1 microns, encompassing both viruses and bacteria. The carbon layer then absorbs volatile gases, such as formaldehyde, toluene, and TVOCs, achieving a CTC rating surpassing 80%. Finally, the catalytic decomposition layer facilitates the molecular breakdown of formaldehyde into CO2 and water, a process that obviates the need for filter replacement.
These combined layers specifically target up to 14 distinct indoor pollutants, including dust mites, pet dander, formaldehyde, and ammonia, as well as nine bacterial viruses, such as influenza variants and human coronavirus strains.
Smart Monitoring and Control
The PM20 is outfitted with seven highly accurate sensors, constantly assessing the air inside your space. It keeps tabs on PM1, PM2.5, PM10, formaldehyde, TVOCs, temperature, and humidity levels. An easy-to-read LCD screen displays real-time air quality data, giving you a clear picture of the pollutants the purifier is identifying and eliminating.
If you want a more detailed look, the Dreame App offers a complete air quality history, pollutant tracking, and smart scheduling options. You can control the purifier with your voice, even without an internet connection. The app also sends notifications when it’s time to replace the filter, helping your purifier run at its best.
Year-Round Comfort
The PM20 goes beyond mere air purification; it’s a comfort device for all seasons. Its integrated PTC heating element can hit 40°C (104°F) in a mere three seconds, delivering quick warmth when the temperature drops. Come summer, it transforms into a robust fan, effectively pushing cool air around your space. This adaptability makes it a strong 3-in-1 option, earning its place in your home.
Design and Usability
The purifier’s design is both contemporary and practical, featuring a sleek bronze and white finish that complements modern interiors. While its dimensions—38 x 38 x 85 cm (15 x 15 x 33.5 inches)—are considerable, Dreame has cleverly incorporated concealed wheels on the base, allowing for effortless relocation between rooms without the need for heavy lifting.
The bulbous head gives the design a somewhat robotic look, a feature that certainly sets it apart visually.
When in Comfort Mode, the purifier runs at a mere 32 decibels—quiet enough to let you sleep soundly. This makes it a good choice for bedrooms and other areas where noise could be a problem. There’s also a Pet Mode, which boosts airflow to better capture pet hair and odors, making it a good fit for homes with furry friends.
Pricing and Value
The AirPursue PM20 originally had a list price of $999.99, but early discounts have brought it down to roughly $699-$770 on different sites. This higher price point reflects its advanced features and the fact that it can do multiple things. Replacement filters add to the overall expense: the carbon filter retails for $59.99, while the high-efficiency composite filter is priced at $99.99.
To put things in perspective, the smaller PM10 model is available for $899.99, providing a more economical option, though it lacks the heating feature. The PM20, with its distinctive tracking technology, 3-in-1 capabilities, and seamless smart home integration, presents a compelling value proposition when stacked against other high-end purifiers.
Practical Considerations
For expansive homes and open-plan layouts, the PM20 emerges as a sophisticated choice. Its capacity to channel airflow directly towards people ensures you’re always inhaling the cleanest air, and the blend of swift room purification with heating and cooling functions minimizes the need for multiple devices.
That said, prospective buyers should weigh the considerable footprint and recognize this as a premium purchase. For those with limited space or a tighter budget, Dreame’s PM10 model or similar options might be worth considering. Also, don’t forget to account for the cost of replacement filters when thinking about the long haul.
In summary, the Dreame AirPursue PM20 offers a fresh take on home air quality. It combines sophisticated filtration with smart AI and the ability to work well in different seasons. The radar-guided Follow Mode is like something out of a sci-fi movie, but it’s real, and the four-layer filtration system and dual-outlet design make sure every corner of your room gets the same level of clean air.
If you’re serious about improving indoor air quality in a larger space, especially if you appreciate the latest smart home tech and want year-round comfort, the PM20 is a strong contender. It’s a premium purchase, designed to do more than just clean the air; it’s meant to elevate your entire indoor living experience.
