An indoor ventilation system is needed to ensure air exchange, i.e. to maintain an optimal CO2 level in the room. To do this, it is necessary to ensure the supply of fresh air (naturally or by force) and the disposal of exhaust air, along with excess moisture and odors. The correct and most common option is filtered supply ventilation combined with efficient exhaust ventilation.
Proper air exchange ensures a comfortable microclimate in the rooms where people are located. If the air exchange is not organized, it will negatively affect both the health of the person and the house or apartment. For example, mold can grow in poorly ventilated bathrooms.
Why do you need supply ventilation with a filter?
First, you need to understand why you need supply ventilation with air purification. People regularly stay in an apartment or house, inhaling clean air and exhaling CO2. Accordingly, a sufficient amount of carbon dioxide is concentrated in living quarters, and in bathrooms and kitchens, moisture and odors also enter the air.
Compared to an apartment, the air outside can already be called clean – but only if you focus on the CO2 content. Nevertheless, it contains unpleasant impurities, such as dust. If you live near a large avenue or some kind of enterprise, odors will be added to the dust. For example, you can often smell burning or car exhaust. Equally often, allergy sufferers are disturbed by poplar fluff and plant pollen. In general, all those unpleasant aspects, including insects that get into an apartment or house when you open a window.
How to choose ventilation with a filter?
Before choosing a particular filter equipment, you need to understand how much air it will have to process. There are three ways to calculate air exchange.
By multiplicity, according to DBN standards. For each room, taking into account its size and purpose, it is calculated how many times the air should be changed over a certain period of time.
By the number of people. As a rule, in a house or apartment, each family member has his or her own room, and there is a room where the whole family gathers. Taking into account how many people are regularly in a particular room, air exchange is calculated. Thus, for the minimum level of comfort, 15 m3/hour per person is taken, for the optimal level – 25 m3 per person, and for increased comfort – 36 m3/hour.
By CO2 level. Perhaps the most effective method. In this case, a sensor is installed in each room that measures the level of carbon dioxide and regulates the supply and intake of air. The advantage of this method is that no matter how many people are in the same room, they will always be equally comfortable.
Taking into account the above information, you can choose the right equipment.
