Dreame Air Purifier PM20

DREAME Air Purifier PM20

The Dreame AirPursue PM20 is a 3-in-1 air purifier, heater, and fan built for large rooms and open-plan spaces. It uses AI-driven airflow tracking to direct clean air toward people in the room, combined with a 4-stage filtration system rated to capture 99.99% of common airborne pollutants. It's designed to refresh a 1,883 sq.ft. space in about 15 minutes and can cover up to 7,534 sq.ft. in an hour.

Features

• Dualflow Modulation airflow – two airflow patterns (forward + upward, or long-range forward) that speed up full-room circulation
• Enviro Detect tracking – senses people in the room and directs airflow toward them; adapts when multiple people are present
• Auto-on by presence – purifier can power on automatically when someone enters the room (app-customizable)
• 3-in-1 operation – purifier, heater (PTC heating, warms to 40°C in about 3 seconds), and fan/cooling mode in one unit
• 4-stage filtration – magnetic pre-filter housing, H13-grade composite filter, activated carbon layer, and a formaldehyde-catalyst filter
• 10 fan speeds, 3 modes for adjusting strength and airflow type
• Long-range air projection – purified air can reach up to 10 meters
