Radon is a colourless, odourless, and tasteless gas, meaning its presence cannot be detected by human senses. The only reliable way to determine radon levels is through measurement. Testing is particularly recommended for older buildings, homes with basements, properties located in areas with a high radon index, or when there are health concerns potentially linked to prolonged indoor exposure.

If measurements indicate radon levels above those recommended by the World Health Organization (100–300 Bq/m³), action should be taken immediately to reduce exposure. The first step is to analyse the causes and propose appropriate corrective measures. This is followed by the installation of a suitable system — such as specialised heat recovery units or other technical modifications — to permanently lower radon concentrations. The sooner these measures are implemented, the quicker the associated health risks can be reduced.

An anti-radon system operates continuously throughout the year, automatically regulating the intake of fresh air and the extraction of radon-laden air. During winter, it preheats incoming air via heat recovery, while in summer it contributes to maintaining a comfortable indoor climate. Maintenance typically involves regular filter replacement and an annual professional inspection. Operating costs are low and negligible when compared to the significant health benefits.

Yes. These units are equipped with a radon sensor that continuously monitors indoor radon levels. Based on the readings, the system automatically adjusts its operation to maintain the lowest possible concentration. Remote access is also available, enabling you to monitor not only radon levels but also CO₂ concentration and other air quality parameters. To ensure long-term effectiveness, regular maintenance — particularly timely filter replacement in accordance with the manufacturer’s recommendations — is essential.
