In every household, good ventilation is necessary to maintain healthy air in the home. In many houses, however, the ventilation is poor. However, the consequences of poor ventilation in the home are greater and more serious than most people think. Draughts, moisture and health complaints are common consequences of poor ventilation. Old houses are usually poorly insulated, meaning that fresh air can enter the house through seams and cracks – this and deliberately opening windows and doors is called natural ventilation. In modern, well insulated houses, outside air has no chance to enter the house. It is therefore necessary to actively ensure that fresh air can enter the house. This is often done by placing ventilation grilles or installing a balance ventilation system.
In order to ventilate your home properly, it is important to ensure that ventilation grilles and vent windows are open day and night. This way you can ensure the continuity of fresh outside air flowing in. Extra ventilation is often desired after cooking, by means of an extractor fan, after showering, by means of a bathroom fan and while sleeping, by means of a mechanical ventilation system in your bedroom. Just airing the house by opening windows or doors is not enough. After half an hour there is nothing left of this fresh air, so moisture and harmful substances can accumulate in the house again. Good ventilation is therefore very important and indispensable in every household!
A lot of moisture is produced in a house daily by the residents, pets and plants, among others. Cooking air, smoke and dust mites also contribute to air pollution in the home. By ventilating, this moist and polluted air is removed from the house. Good ventilation is indispensable – especially if your house is well insulated! The polluted indoor air will otherwise linger in your home, causing you to suffer from various health complaints such as headaches, fatigue and dizziness.
Are you wondering whether you have sufficient ventilation and clean air in the house? You can measure this with a CO2 meter. A CO2 meter measures the CO2 concentration in the indoor air so you know when extra ventilation is needed. Not only is this good for your health, you can also save money and energy by only ventilating when needed.
A lack of ventilation or inadequate ventilation can cause mould and house dust mite in the home, which can lead to health problems. Complaints that can occur as a result of insufficient ventilation include shortness of breath, coughing, fatigue, headaches and chronic colds. If you suffer from asthma or other allergies, good ventilation is also very important. Do you suffer from these complaints and do you think this is due to poor ventilation? Contact your family doctor as soon as possible and get advice on how to improve the indoor environment in your home.

Good ventilation is of course just the start of optimising the indoor climate in your home. To ensure that your health does not deteriorate in your own home, you can take the following steps:
- Install sun blinds
- Ensure proper maintenance of your boiler and ventilation system
- Have the old open boiler (if any) replaced by a new central heating boiler
- Keep carpets and curtains free of dust and clean
- Provide extra ventilation after and during cooking and showering
- Do not smoke in your home
- Tackle any moisture problems
Even if you think that the outside air is more polluted than the air in your home, you need to ventilate. The indoor air is almost always more polluted than the outside air. Do you live on a busy road or near an industrial estate? Then only open the windows and doors as far away from there as possible. This way you ensure that the cleanest air can enter your home.
If there is a disaster or are there chemicals in the open air near you, then immediately close your windows and doors! However, outside air does not only enter your home through open windows and doors, but also through ventilation grilles and any mechanical ventilation system that may be present. In the event of a disaster, ensure that all ventilation grilles are closed and that the mechanical ventilation system is switched off. If there is a collective mechanical ventilation system that you cannot turn off, set it to the lowest possible position so that as little harmful air as possible can enter your home.
Poorly ventilated spaces and homes can quickly create an unhealthy living environment. As people live in these rooms, the indoor air is polluted by people breathing, cooking, heating, washing and showering, among other things. An average family provides 14 to 20 litres of moisture per day. In most skin contents, all kinds of unhealthy substances are often released from clothing, bedding, carpets, parquet, newspapers and cigarettes. In these poorly ventilated situations, fungi and house dust mites are given free rein to develop and reproduce. Bad smells also linger for a long time.
Poorly ventilated rooms are also particularly harmful to people with allergies or sensitivity to certain substances. The polluted dust present in the indoor air can then cause all sorts of different health complaints. Asthma patients, for example, suffer much more from asthma symptoms in poorly ventilated rooms. Good ventilation is indispensable – especially in homes of people with allergies, asthma or hypersensitivity to certain substances!

A big misunderstanding is that ventilating is a waste of energy because the cold incoming air has to be heated again and again. However, ventilation is absolutely not a waste of energy, not only is dry and clean air easier and faster to heat up (and thus also costs less energy), ventilation is also very important for health. Energy can be saved with a new fan such as an Itho cve ecofan box. Is there still an old ventilation unit in your home? Then you can save over £st50 per year with a new energy-efficient direct current Itho extraction fan. In case you have a heat recovery unit in your home, the fresh incoming air is already heated through the heat exchanger, so it takes less energy to heat this fresh air. All in all, absolutely no waste of energy – if you do it right, you can even save energy! For more information on energy efficient ventilation, please read articles on our ventilation blog.
The outside air is indeed often polluted, especially in the vicinity of busy (highways) or industrial estates. What one often does not know, however, is that the pollution in the house is often higher than outside. As people live in a house (often also several people), the air pollution in the house increases enormously. The presence of pets, plants, curtains and carpets, for example, also causes moisture, fine dust and other contaminants to enter the indoor air. Letting in so-called polluted outside air is a relief for the internal living climate. Are you not afraid that you will get too much polluted air in your house? Make sure that you place ventilation grilles on the sides of the house that are not on the road or an industrial estate, i.e. the side where the risk of air pollution is lowest. It is also best to open windows and doors on this side of the house to get fresh air into the house through natural ventilation. For more information we refer you to our ventilation blog, here you can find everything you need to know about ventilation!
Most old houses do not have a mechanical ventilation system at all, but use natural ventilation through cracks and holes in the house. Old houses, mainly built before 1970, are often poorly insulated, so that outside air can easily enter the house. Houses built after 1970 often have a mechanical ventilation system in the house (about 30%). Through mechanical ventilation the fresh air enters the house naturally, through ventilation grilles, doors and windows, while the polluted air is removed mechanically. Some houses even make use of balance ventilation by a heat recovery unit. With a heat recovery unit, both the incoming air and the outgoing air are mechanically controlled. A heat recovery unit also uses heat recycling, which extracts heat from the outgoing air and releases it to the incoming air.

Many people think that ventilation is not necessary, but a poorly ventilated home can cause serious health problems. For example, people who frequently stay in poorly ventilated rooms can suffer from headaches, fatigue and chronic colds. People with a sensitivity to polluted fine dust, allergies or asthma also benefit enormously from a well-ventilated home. Ventilation is essential for good health! Ventilation is not only necessary for your health, it also allows you to save energy and therefore money. As clean and dry air is faster and easier to heat, it costs less energy and less money.
