Clean air and a healthy climate at school, in the catering industry, at work, in childcare facilities, in retirement homes and at home.
From 900 ppm CO2 it is required by law to take action:
If additional ventilation by opening windows and doors is not possible,
then local air cleaning with a mobile device the solution.
We take care of the installation for you, just plug it in and go.
With our (silent) air cleaner
in your school / business / office / nursery / rest home
you have extra protection.
For the catering industryInvest in air cleaning and you can receive visitors at 100% capacity instead of 70% capacity.

Points to consider when choosing an air cleaner
When choosing an air cleaner, consider various elements:
1/ The capacity (in cubic metres per hour) must be sufficient to clean the air in the room at least 6 times per hour.
2/ The filter method must not generate any hazardous by-products. HEPA air filters only filter the finest particles from the air and do not generate any by-products at all.
3/ Operation must be quiet, even in the highest position.
Together we can do it
The coronavirus spreads through the air via airborne particles (aerosols). How do you know if you are breathing other people's breath? The main indicator is the level of carbon dioxide (CO2) in the air. CO2 is the gas that we exhale when we breathe.
It is well known that checking the CO2 level is useful to see whether a room is well ventilated or not. In a well-ventilated room there is usually less coronavirus in the air, and all we want is less virus in the air! If ventilation is not enough to get below 900 ppm CO2, it is necessary to install an air cleaner.
In early 2022, Prof. Bert Blocken took the initiative to set up a research project "Air purification in the classroom", and more than 50 schools in Belgium and the Netherlands are already taking part in this project to measure the effect of air purification on aerosols and the effect on the number of infections.
When you have readings above 900 ppm CO2 in your classroom, you need to improve ventilation. If that does not work, it is interesting to install an air cleaner. This is a mobile device, which you can install by simply plugging it into the wall socket.
Continuous measurement of CO2 and particulates is vital
CO2 sensors are often "shared" in schools. A CO2 profile of each classroom is measured for one day or one week and this is then taken as the reference for the rest of the school year. That is wrong!
The CO2 level depends on many factors. Occupancy, activity, temperature, relative humidity, ... A measurement for one week is therefore no reference for the other weeks. It is a bit like measuring the temperature in your living room for one day and then adjusting the heating to this profile. We all know that will not work.
To create a safer environment in classrooms, CO2 and fine dust (PM1, PM2.5, PM4, PM10) must be measured continuously.
Proper measuring is important
Don't be fooled. Many hand-held CO2 and particulate matter sensors on the market do not suffice to measure correctly.
The only correct way to measure is with a so-called NDIR CO2 sensor. This is also what the Flemish Care and Health Agency indicates as well as the Taskforce Ventilation of the Governmental Commission Corona.
In addition, the measurement error is also very important. This is the extent to which the displayed CO2 value can deviate from reality. As indicated by the Flemish Care and Health Agency it may not exceed 10 % at 900 and 1500 ppm (and 5000 ppm for devices capable of measuring up to 10000 ppm). Taskforce Ventilation of the Governmental Commission Corona then gives 10% up to 2000 ppm
We use qualitative NDIR sensors which are the only correct way to measure CO2.
Our used CO2 sensor more than meets these guidelines.
For the nerds:
- NDIR
- Accuracy: ± (50 ppm+5% value)
- Range: 0 - 5000 ppm (increased range from 14 June 2021)
- Configurable warning levels
Accurate
An air quality meter is only useful if it accurate is.
We have done this as follows.
Complete
Everything necessary for accurate and correct air quality measurements:
temperature, relative humidity, NDIR CO2, particulate matter PM1, PM2.5, PM4, PM10, VOC, light and noise.
The carefully selected Sensirion SP30 fine dust sensor is MCERTS certified!
