Indoor air purification - air quality & recommendations

Indoor spaces accumulate pollutants such as VOCs (volatile organic compounds), particulate matter, mold spores, and allergens. Sources include furniture, building materials, cleaning products, cooking, pets, and inadequate ventilation.

Poor indoor air quality can be identified by a stuffy smell, increased humidity, fatigue, headaches, or irritation of the eyes, nose, and throat. A CO₂ meter can indicate the exact condition.

Ventilate regularly (2-4 times a day), minimize sources of pollutants (smoke-free rooms, low-pollutant materials), place plants, and occasionally filter with an air purifier.

Yes, plants like peace lily, ivy, or snake plant slightly improve air quality by reducing pollutants and regulating humidity. However, their impact is limited and does not replace thorough ventilation or air purifiers.

Air purifiers suck in room air, filter it through HEPA filters (removes fine dust and allergens) and activated carbon filters (binds odors and VOCs) and return the purified air to the room.

Devices with HEPA H13 or H14 are ideal because they reliably remove over 99.95% of the finest particles, such as pollen, house dust mites or pet hair.

An air quality sensor is useful because it measures CO₂, particulate matter, or VOC levels and tells you directly when you need to ventilate or when the air purifier should be operated more intensively.

No, air purifiers do not remove oxygen or CO₂. Regular ventilation is necessary to provide fresh air and reduce CO₂.

Most appliances consume between 10 and 70 watts. At low power, this equates to approximately CHF/EUR 10–30 per year; when used continuously at the highest power level, it costs significantly more. Automatic modes help save energy.

Many modern air purifiers have a quiet night mode with noise levels below 30 dB (comparable to a whisper). This is especially important for bedrooms or children's rooms.

Older buildings often have natural ventilation (leaky windows), but more frequently have moisture problems (risk of mold). New buildings are airtight and require targeted ventilation (e.g., controlled living space ventilation), but often initially emit harmful gases.

Depending on usage and manufacturer's specifications, this usually occurs every 6–12 months. Regular maintenance is important to ensure optimal cleaning performance.

Yes, many models offer smart home integration via Wi-Fi or Bluetooth. This allows you to control devices automatically and monitor air quality at any time via the app.
