“We should bring some fresh air into the room!” is a sentence we will utter when we really become aware of the lack of oxygen in the room, which means that in fact it should have been done much earlier. Did you know that on average, in one day we inhale and exhale almost 30,000 times and that one family of four, as a result of daily activities such as cooking, bathing, watering and cleaning, produces as much as 12 L of water vapor, which definitely needs to be ventilated from the apartment?
