Breathing clean air inside the home is essential for our health and daily comfort, but the importance of proper air recirculation and frequent air changes is often underestimated. A closed and poorly ventilated environment can favor the accumulation of harmful substances such as carbon dioxide, fine dust and volatile organic compounds, with negative consequences on health and well-being.

With the evolution of construction techniques and the improvement of thermal insulation in modern homes, natural air exchange has become increasingly limited. This has made it necessary to adopt targeted solutions to guarantee clean and oxygenated air in closed spaces, without compromising the energy efficiency of the home.

Why good air circulation is essential in the home

Proper air circulation is essential to prevent the accumulation of harmful substances that can have a direct impact on health. The absence of adequate air flow can lead to several problems:

• Accumulation of carbon dioxide (CO2): a stagnant air environment can cause fatigue, difficulty concentrating and headaches
• Presence of allergens and pollutants: fine particles, pollen and volatile organic compounds accumulate in closed spaces, aggravating allergies and respiratory problems
• Proliferation of bacteria and viruses: stagnant air also favors the spread of pathogens, increasing the risk of disease
• Appearance of mold and humidity: without adequate air exchange, humidity tends to condense on the walls, creating conditions favorable to the formation of mold that is harmful to health and to the structure of the building

In closed environments, the sick building syndrome often occurs, a condition recognized by the World Health Organization (WHO) that links poor indoor air quality to ailments such as eye irritation, respiratory problems and drowsiness. To avoid this, it is essential to ensure adequate air renewal in the home.

How to ensure effective air recirculation

To improve indoor air quality, you can adopt different strategies, but not all are equally effective.

Natural ventilation, obtained simply by opening the windows, is the most common method. However, it has several limitations: it depends on the external climatic conditions, it doesn't guarantee a constant exchange of air and, in urban areas, it can introduce pollutants instead of eliminating them.

A more effective and controlled solution is provided by Heat Recovery Ventilation (HRV) systems, which ensure a continuous and filtered air flow, eliminating pollutants without dispersing heat. HRV technology allows you to:

• Extract stale air and replace it with clean, filtered air
• Remove excess humidity, preventing the formation of mold
• Avoid wasting energy thanks to heat recovery

The importance of humidity in keeping the air in our homes healthy

One of the most neglected aspects of air quality control is humidity regulation. Excessive humidity can cause condensation on surfaces, favoring the formation of mold and the deterioration of building materials. On the contrary, excessively dry air can cause respiratory problems and irritation of the mucous membranes.

Maintaining the right humidity balance in the home is essential for the well-being of its inhabitants. An HRV system with heat recovery helps to regulate indoor humidity, avoiding excess and maintaining a healthy climate all year round.

Air recirculation technologies: HRV as the ideal solution

Today, Heat Recovery Ventilation (HRV) systems are the most advanced solution for guaranteeing an effective and continuous air flow. Unlike natural ventilation, HRV allows you to maintain optimal air quality without wasting energy.

Thanks to the filtration of the incoming air, the HRV blocks fine dust, pollen and atmospheric pollutants, ensuring a healthier home environment. Furthermore, with heat recovery, these systems avoid thermal losses, contributing to the energy efficiency of the house.

The adoption of a Heat Recovery Ventilation system allows you to:

• Ensure constant air exchange without waste
• Reduce the accumulation of humidity and mold
• Eliminate pollutants and improve the health of the inhabitants
• Optimize living comfort in all seasons

Good air renewal in the home not only improves the liveability of the rooms, but also represents a strategic choice for long-term well-being. Investing in an efficient ventilation system means protecting your health and improving the quality of your daily life.
