Cause we all need fresh air...

Ventilating your home properly is extremely important for your health and the indoor climate of your home. Because, especially modern homes, are well insulated and tightly sealed, a supply of fresh air is needed. The very best way to keep the air in your home healthy is to ensure continuous air exchange, 24/7 and 365 days a year. In addition, you ensure a healthy indoor climate by:  
- Opening windows regularly 
- Cooking with the lids on the pans
- Leaving the hood on during and up to 10 minutes after cooking
- Drying off the tiles after showering
- Leaving a bathroom window or door open after showering
- Grates and ventilation
This may cost energy but, above all, should not be seen as wasteful. More information and additional tips on energy conscious ventilation can be found here.
