The 13 best ventilation tips from Nedco

That is good. A ventilation unit ensures good ventilation in your home. But it is important to have this unit checked every two years by a service technician. Never turn off the ventilation unit. This will maintain optimal ventilation in your home. And remember to set the switch to the highest position regularly. Only at the highest setting will sufficient polluted air be extracted. The valves must also be cleaned at least once a year. In addition, ensure that air can flow through the house by having space under or above internal doors, or by having a vent in the doors.

To summarise:
- Always leave the unit on (except when the authorities advise that windows and doors should be closed).
- Set the switch to the highest position regularly (preferably every day).
- Clean the valves at least once a year with soapy water.
- Ensure there is space under or above internal doors so that air can flow through the house.
- Have a service technician come every two years to maintain the unit.

Read this article to check whether there is sufficient ventilation in your house. Ventilation is enabled by joints or gaps and through vents, tilt and turn windows, etc.

When using the dryer, ensure extra ventilation by turning the central ventilation to its highest setting or by opening a window or door. Hang the laundry out to dry outside as much as possible.

Ensure that the room where the laundry is dried has additional ventilation by opening a window. Dry the laundry outside as much as possible.

When the fireplace or wood burning stove is in use, extra ventilation is needed to supply oxygen and remove harmful substances. This could be provided by opening a tilt and turn window, for example.

It is better not to smoke in the house. Smoking (and passive smoking) is harmful and also increases the effects of other harmful substances in the home. If you do smoke in the house, then ensure you have enough additional ventilation by opening a window or door.

With new furniture or materials, a lot of VOCs (volatile organic compounds such as solvents in glue or paint) are released during the first few months. These substances can affect your health and cause issues such as headaches, fatigue or irritation of the mucous membranes. It is therefore important to ventilate especially well in the beginning.

Ventilate mainly on the side of the house which is further away from the busy road. During peak hours it is better to ventilate a little less. Special sound-absorbing vents are available which allow continuous ventilation without additional noise pollution. Even in a relatively polluted environment, ventilation is important. There are many harmful substances in the house that accumulate when there is no regular ventilation. Regular cleaning of vents is especially important along a busy road.

A sufficient supply of fresh air is very important for a tankless water heater. Otherwise, carbon monoxide may be released during incomplete combustion. Carbon monoxide is very dangerous and even deadly when oxygen is depleted. In the room where the tankless water heater is located there must always be a vent or opening of at least 2 cm through which fresh air can enter. Gas water heaters and other gas appliances should be checked, cleaned, and adjusted at least once a year.

Mould in the house indicates a problem with moisture and therefore ventilation. Insufficient ventilation in the house results in damp. You probably need professional help to solve this problem. Mould in the bathroom can be remedied by increasing ventilation. If mould can be seen in other places in the house, there may be a structural problem. It is important to call in a professional.

Leave these vents open as much as possible to maintain healthy air in the house. Clean vents regularly, for example with a vacuum cleaner. Only clean vents will work optimally. Check that there is enough space under the doors in the house to allow fresh air to flow through. If necessary, door vents can be installed to improve the flow.

Open these windows regularly and preferably daily. Sufficient fresh air can flow in through these windows. Check that there is enough space under the doors in the house to allow fresh air to flow through. If necessary, door vents can be installed to improve the flow.

Ventilation then takes place through any joints and gaps in your house. This ventilation cannot be adjusted and is highly dependent on weather conditions. Check what options there are to improve ventilation. Install vents in window frames on several sides of the building. With a vent you can regulate how much ventilation you need.
