We spend on average 90% of our time indoors, whether in the office, in shops, or at home. In these enclosed spaces, the air can sometimes be up to five times more polluted than the air outdoors. While air conditioning is often perceived solely as a tool for thermal comfort, it actually plays a "lung" role for the building. If poorly maintained, it can become a source of nuisances; but when well managed, it is the best defense against pollutants, allergens, and viruses. At Climatik, we believe that air at the right temperature is nothing if it's not, first and foremost, pure air.

1. Air conditioning: much more than just a matter of temperature

A modern air conditioning system is not just a simple air refrigerator. It is a treatment plant that acts on three fundamental levers of air quality:

Particle filtration

The air blown by an air conditioner systematically passes through filters. These capture dust, pollen, pet dander and, for the most advanced models, fine particles and bacteria.

•  The impact: An immediate reduction in allergic symptoms and respiratory tract irritations.

Humidity control

Humidity is a key factor in IAQ. Air that is too humid promotes the proliferation of dust mites and mold. Conversely, air that is too dry (below 30%) irritates mucous membranes and facilitates the transmission of airborne viruses.

• The role of the air conditioner: In cooling mode, it naturally dehumidifies the air. Some sophisticated systems even allow maintaining an ideal humidity level between 40% and 60%.

Air renewal

Certain air conditioning systems (notably ducted systems or air handling units - AHUs) are coupled with a fresh air intake. This helps to dilute the CO2 concentration emitted by human occupation.

2. Risks of poorly maintained air conditioning

It is important to be candid: a neglected system can degrade air quality. This is the famous "sick building syndrome."

• Microbial proliferation: If condensates (condensation water) stagnate in the tray due to poor drainage, bacteria (like Legionella) or fungi can develop there.
• Redistribution of pollutants: A saturated filter no longer retains anything. Worse, it can release clusters of dust and spores into the ambient air with each start-up.
• Unpleasant odors: "Musty" or "dirty sock" odors are often a sign of bacteria settled on the heat exchanger.

3. How to improve your indoor air? Climatik solutions

To transform your air conditioning into a true health shield, several technologies and best practices can be deployed.

Choosing the right filters

Different filtration levels are available depending on your needs:

1.  Standard filters (G3/G4): For coarse dust.

2.  Activated carbon filters: Excellent for neutralizing odors and volatile organic compounds (VOCs).

3.  HEPA filters (High Efficiency): Capable of stopping 99.97% of 0.3 micron particles, including most viruses.

Active purification technology

At Climatik, we are increasingly installing systems that include ionization or UV-C lamps.

• Ionization: It charges air particles with static electricity, forcing them to clump together for better capture by filters or to fall to the ground.
• UV-C lamps: Installed inside the units, they destroy the DNA of microorganisms, ensuring a sterile exchanger.

The importance of air change rate

To ensure healthy air, it's not enough to recycle it; it must be renewed. The fresh air flow rate (Q) is calculated based on the number of occupants (n) and the activity:

Q (m³/h) = n x q

Where q is the regulatory flow rate per person (e.g., 25 m³/h in a standard office).

If your air conditioning does not allow for fresh air intake, Climatik recommends installing a dual-flow CMV coupled to recover heat while ensuring perfect oxygenation.

4. The 5 golden rules for daily air quality

To keep your installation healthy between technician visits, here are our experts' tips:

1.  Clean your filters every 3 months: A simple operation that makes all the difference for your health and energy consumption.

2.  Do not over-air condition: A temperature difference of more than 7°C with the outside unnecessarily dries the air and fatigues the body.

3.  Ventilate for 10 minutes a day: Even with air conditioning, nothing replaces a good natural draft to remove indoor pollutants.

4.  Monitor drainage: If you see water dripping or stagnating, immediately call your maintenance service.

5.  Maintain a stable humidity level: Use a small hygrometer to ensure you stay within the comfort zone (45-55%).

Why choose Climatik for the health of your employees?

The mission of Climatik goes beyond simply installing equipment. We are experts in the air you breathe.

• IAQ (Indoor Air Quality) Audit: We use particle and CO2 sensors to diagnose the health of your premises.
• Sanitary maintenance contracts: Our technicians don't just check gas pressures; they perform a complete disinfection of the networks with certified non-toxic products.
• Filtration advice: We adapt the type of filter to your activity (medical office, dusty workshop, open-plan offices).

Conclusion

The impact of air conditioning on indoor air quality is significant. Far from being a mere source of coolness, it is the primary tool for controlling your respiratory environment. A well-chosen system, intelligently regulated, and rigorously maintained by Climatik teams guarantees improved productivity, reduced absenteeism, and unparalleled daily comfort.
