To choose a good air purifier for a living room of 60-70 m²

To choose a good air purifier for a living room of 60-70 m², you need to pay attention to the following factors:

---

1. Effective Coverage Area (CADR – Clean Air Delivery Rate)

CADR is the most important indicator, showing the volume of clean air the purifier can produce per unit of time (usually m³/h). For a 60-70 m² room to have effective purification, you should choose a purifier with a CADR of around 400 – 700 m³/h or higher (depending on ceiling height and pollution levels). A simple calculation is CADR = room area × ceiling height × 3-5 air changes per hour. For a 60-70 m² room with a ceiling height of 2.5-3m, you’ll need a CADR of approximately 60×2.5×3=450 m³/h to 70×3×5=1050 m³/h.

2. Filtration System

• Pre-filter: Traps large dust particles, pet hair, and human hair.
• HEPA filter (High-Efficiency Particulate Air): This is the most crucial filter. It cleans 99.97% of fine dust particles (PM2.5), pollen, mold spores, bacteria, and viruses that are microscopic in size. You should choose a purifier with a HEPA H13 standard filter or higher.
• Activated Carbon Filter: Absorbs odors, cigarette smoke, and harmful gases (VOCs, Formaldehyde).
• Additional Filtration Technologies:
  • Negative Ions/Plasmacluster Ions: Helps eliminate bacteria, viruses, mold, deodorize, and enhance air freshness.
  • UV-C: Kills bacteria and viruses.
  • Humidification (if needed): Some purifiers integrate a humidification function, which is useful for dry climates or when using air conditioning.

3. Smart Features and Conveniences

• Air Quality Sensor: Automatically detects and displays pollution levels (PM2.5 fine dust, gases, odors), adjusting fan speed accordingly.
• Auto Mode: The purifier automatically adjusts its operation based on air quality.
• Sleep Mode/Quiet Mode: Reduces noise during nighttime operation.
• Timer: Schedule when the purifier turns on/off.
• Remote Control/App Connectivity: Conveniently control the purifier remotely via your smartphone.
• Filter Replacement Alert: Notifies you when filters need to be replaced to ensure purification effectiveness.

4. Noise Level

Your living room is a common living space, so choose a purifier with low noise levels (typically below 50dB at the highest setting and below 30dB in sleep mode) to avoid discomfort.
