Air Quality What is a particulate matter sensor?

Fine particulates are tiny dust particles smaller than 10 micrometres (µm) that you can't see with the naked eye, but which still affect the air you breathe. A particulate matter sensor makes this invisible air pollution visible: the device measures the amount of (fine) dust particles in the air, expressed in PM (Particulate Matter), giving you a simple and clear insight into the air quality in a given space. That way, you know exactly when it's time to ventilate, and you protect your own health and that of others. Good particulate matter sensors often have multiple functions, measuring not only particles below 10 µm but also below 2.5 µm, as well as CO2, humidity and other volatile gases.

Air Quality How do I measure the air quality in my home?

How clean is the air in your home, really? With a simple check, you can find out in no time. Measuring the air quality in your own home is actually not complicated at all! With a CO2 monitor or particulate matter meter (sometimes also called an air quality meter), you can see straight away whether the air quality in your home is good (enough) or not. If it isn't, you immediately know that extra ventilation is needed. In this blog, we explain how you can measure the air quality at home quickly and easily, what healthy indoor air quality actually means, which substances can cause poor(er) air quality, and what the relevant requirements and regulations are.

Ventilation What is the difference between an air vent cover and an air valve?

An air vent cover and an air valve seem, at first glance, to do the same thing: they let air in or out of a specific space, such as your home. Yet they are two very different products, each with its own place and function. In this blog, we'll first show you the visual difference, and then get to the heart of the matter: when do you use an air vent cover, and when do you use an air valve?

Installation & maintenance Installation MVHR ventilation system and mounting tips

Installing an MVHR unit is very achievable. However, you do need to know what to look out for. An MVHR system (mechanical ventilation with heat recovery) ensures a healthy indoor climate by continuously supplying fresh air and extracting stale air, while recovering the heat from the extracted air. That's efficient, but it does require the MVHR unit installation to be done correctly. Whether you want to install an MVHR system yourself as a DIY enthusiast, or simply want to understand how connecting an MVHR unit works: in this blog we take you through everything you need to know, step by step. From the right mounting position and electrical connection to duct selection, sound insulation and commissioning your MVHR installation.

Ventilation What is demand-controlled ventilation?

Demand-controlled ventilation automatically adjusts based on the air quality in your home. It ventilates more when needed and less when it isn't. The result: a healthy indoor climate and lower energy consumption, without any effort on your part. In 2026, demand-controlled ventilation is the standard in modern mechanical ventilation systems and heat recovery units. In this blog, you'll find everything you need to know about demand-controlled ventilation and which products from our range are suitable!

Air Quality Our tips and tricks for ventilating in summer

The temperature outside is rising quickly: summer is here! Warm weather is often lovely, and we spend a lot of time outdoors. What is less pleasant is the heat slowly entering your home. The result? An uncomfortable and sometimes even unhealthy indoor climate. Many people keep windows and doors closed during the day or even switch off the mechanical ventilation in their home. That is not the right way to fight heat. By ventilating at the right times and consciously managing the indoor climate, you can keep the air in your home fresher, healthier and more pleasant. In this blog, we tell you more about this.
