Everything about indoor air quality.

What is air quality?

Air quality is an indicator of the quality of the air. Depending on the degree to which sources of pollution are present in the air, a distinction can be made between clean and polluted air. Polluted air is caused by various sources of pollution floating in the air.

Fine dust

Our air purifiers filter fine dust as small as 2.5 micrometers (PM2.5). For reference, a fine dust particle is 1/30th the size of a human hair.
allergy

Pollen

Pollen is the name for the flower pollen that is spread by the wind and remains in the air. About 1 in 8 people are allergic to it.

Cooking fumes

Although many people find the odors released during cooking pleasant, the cooking fumes released during food preparation are actually harmful to inhale.

House dust mites

House dust mites are tiny arachnids that like to nest in fabric products, such as upholstered furniture, curtains, and bedding. Their waste can cause allergic reactions.

Chemicals

Chemicals are chemicals found in many of our everyday products; think of cosmetics like perfume or deodorant, scented candles and cleaning products.
pets

Pet dander

More than half of all families worldwide have a pet. What many people don't know, however, is that floating hair and dander from our faithful four-legged friends can be harmful to our health.

Smoke

Although we all recognise the harmful smell of smoke, smoke also has a negative impact on indoor air quality.

The importance of clean and healthy air

Poor air quality has a major impact our health. In many cases, indoor air is more polluted than outdoor air. Because we spend most of our time indoors these days, exposure to poor air quality puts us at risk for a variety of diseases such as stroke, heart disease, lung cancer, and both chronic and acute respiratory conditions.

How do you measure air quality?

Indoor air pollution is often invisible. Tiny particles are 30 times smaller than a human hair, so you can’t rely on sight alone. The easiest way to monitor air quality is with a PM2.5 laser sensor. This sensor, built into devices like the Bright 2, measures fine particulate matter in micrograms per cubic meter (µg/m³).

  • 0–20 µg/m³: Excellent to good air quality
  • 21–75 µg/m³: Moderate to slightly unhealthy
  • 76–999 µg/m³: Unhealthy to hazardous

By keeping track of these levels, you can take action to improve the air you breathe at home, protecting your health and comfort.

Symptoms of bad air quality

Contrary to popular belief, polluted air is not only noticeable with asthma, allergies or hay fever. Health complaints such as tightness in the chest, dry skin, eyes or throat and headaches indicate that the air quality indoors is polluted.

Headaches

Poorly ventilated air with high CO2 and pollutants can reduce oxygen levels, leading to headaches and general discomfort.
allergy

Allergies

Poor air quality can trigger allergic reactions, worsening breathing difficulties, sneezing, or congestion.

Coughing

Coughing is a natural response to clear irritants and pollutants from the lungs, throat, and airways.

Concentration

Low oxygen from polluted air can make it harder to focus, think clearly, and stay alert.

Airway irritation

Polluted air can inflame your airways, leading to irritation in the throat, windpipe, or nasal passages.

Fatigue

Breathing air with high CO2 or pollutants can leave you feeling tired, sluggish, and less energetic.

Shortness of breath

Inhaling pollutants, chemicals, or dust can irritate the lungs, causing difficulty breathing or a tight chest.

How to improve poor indoor air quality

If the air in your home feels polluted, an air purifier can help. These devices draw in air, remove pollutants with a multi-layer filter, and release clean air back into the room. Some purifiers also release negative ions, which help fine dust particles settle so they can be captured more easily.

To choose the right air purifier, check the Clean Air Delivery Rate (CADR). The CADR shows how many cubic meters of air the purifier can clean per hour. A higher CADR means the device can clean the air faster and is better suited for larger rooms. Always match the CADR to your room size for optimal results.
