Yes, they do. Air purifiers are highly effective in capturing airbornepollutants like dust, pollen,smoke, and even harmful chemicals. Youmay notice improvements in air freshness and reduced odors withinminutes. Long-term use helps reduce allergy symptoms, improvessleep quality, and supports overall respiratory health.

There's no one-size-fits-all answer, it depends on your environment.In new homes, pollutants like formaldehyde from furniture, paint, andflooring are released gradually in a process called off-gassing. Thisrelease varies depending on materials, temperature, and humidity.That's why continuous purification is key. We strongly recommendrunning your air purifier consistently to capture pollutants as they'reemitted.

Because air doesn't move evenly. Pollutants tend to settle in cornersunder furniture, and in stagnant pockets of air. A high CADR (CleanAir Delivery Rate) means nothing if clean air can't reach those areas.Dreame's DualFlow system pushes purified air farther anddistributes it more evenly, so your whole room gets clean air, not justthe center.

Most air purifiers use 2 to 4 layers of filtration. Dreame air purifiersuse a 4-layer filtration system, each designed to tackle specificpollutants:
1. Pre-Filter: Captures large particles like pet hair, dander, andplant fibers.
2. High-Efficiency Filter: Traps fine particles such as PM2.5,pollen, bacteria, and viruses.
3. Activated Carbon Layer: Adsorbs harmful gases and odors,including formaldehyde, toluene, and other VOCs (volatile organiccompounds).
4. Catalytic Decomposition Layer: Breaks down formaldehyde atthe molecular level into COz and water. It works continuously anddoesn't need replacing.
This layered approach ensures cleaner, healthier air-targeting bothvisible and invisible threats.

The Dreame PM20 comes with a built-in heating feature. You canadjust the target temperature from the current ambient roomtemperature up to a maximum of 104°F(40°C)
