Why do we need to ventilate?
Fresh air is essential to human life. This makes it important for the air around places we spend the most time in, the house, the car, to be clean and safe. Air pollution outside is bad, but if confined in rooms, it can cause harmful effects on our health along with causing problems to the furniture and objects inside.
Fresh air is one of the most important prerequisites for life
However, all air contains a number of different contaminants, in different quantities, depending on the time and place. A great deal of effort is being made to reduce emissions that have a negative effect on our outdoor air, but unfortunately far too little is being done to improve our indoor climate.
Indoor air is, unless we do something to the air en-route, simply outdoor air plus what you’ll ﬁnd indoors. Most materials, e.g. rugs/carpets, paints, screed ﬂooring, chipboard, etc., release so-called emissions. These substances can be allergenic and hazardous to health. The emissions increase at high levels of humidity; humidity itself is the primary cause of rot and mold. These contaminants remain in the indoor climate for longer periods if the airtight houses of today are not adequately ventilated.
The air indoors is often worse than outdoors. Add the fact that we spend around 90% of our time inside, and you quickly realize that a good indoor climate with proper ventilation is extremely important.
