Our blog is about indoor air and air quality

Our blog serves as a guide, a reference, and a source of information. Here you'll find solid expertise, practical advice, and the latest research on air quality and a healthy indoor climate.

Many people sleep worse in the summer, even with the window open. The reason lies in various substances present in the air, which can be measured with the air-Q.
Tips July 30, 2026

Many people sleep with the window open in the summer, yet they still wake up feeling stuffy, tired, or with a headache. The reason is usually a combination of heat, rising CO₂ levels, and a lack of air circulation in the bedroom.

Even at low concentrations, hydrogen fluoride can be harmful to health. That is why it is important to measure hydrogen fluoride—for example, with the air-Q.
Air Quality July 23, 2026

Hydrogen fluoride (HF) is a highly dangerous gas that can be produced, among other causes, by defects or fires in lithium-ion batteries. Find out what health risks exist, what exposure limits apply, and why continuous monitoring with an HF sensor is important for battery warehouses, BESS facilities, and industrial applications.

Implement and verify ventilation concepts using the air-Q
Air Quality June 11, 2026

A ventilation plan ensures an adequate supply of fresh air and protects buildings from moisture and mold. This article explains the requirements of the DIN 1946-6 standard, why replacing windows may necessitate a ventilation plan, and how to monitor air quality using the air-⁠Q.

Fine particles are generated, among other things, by everyday activities such as cooking, heating, and burning candles. These health risks can be avoided by monitoring air quality with the air-Q.
Air Quality June 4, 2026

Fine particles indoors pose an invisible but serious health risk. PM2.5 particles are not only caused by traffic, but also by everyday activities such as cooking, heating, or burning candles. What’s particularly concerning is that this pollution often goes unnoticed. Air quality monitoring makes it visible and enables targeted improvements to indoor air quality.

Inadequate ventilation can lead to excessively high humidity—even in the spring and summer—and, as a result, mold. With the air-Q, this unwanted humidity can be controlled and regulated.
Air Quality May 28, 2026

Indoor humidity is also an issue in the spring and summer. The dew point explains why ventilating can sometimes introduce additional moisture. The air-⁠Q measures air temperature and humidity, detects critical conditions, and uses data to help protect against condensation and mold growth.

Monitoring with the air-Q for a QNG assessment.
Air Quality May 21, 2026

El QNG evaluates sustainable buildings comprehensively and according to clear requirements. But the true quality of a building only becomes apparent in day-to-day use. The QNG, QNG-Plus, and indoor air quality are the focus of attention. Monitoring indoor air quality with the air-⁠Q is becoming increasingly important for quantifying the health and comfort of buildings in operation.

Radon is an invisible hazard and the second leading cause of lung cancer, but it can be measured with the air-Q
Air Quality May 14, 2026

Radon-222 is a naturally occurring radioactive gas that can enter homes through cracks and crevices. It increases the risk of lung cancer, but remains invisible. With the air-⁠Q, you can continuously monitor radon levels, detect elevated levels, and take specific measures to protect your indoor air quality.
