How your indoor climate affects your health.

How your indoor climate affects your health.

Our working lives are undergoing some enormous changes right now, with COVID-19 meaning many people are working from home. And to ensure you keep performing at your best while at home, you will need more than just a laptop and office equipment: you will also need a good indoor climate.

A study from the prestigious Harvard School of Public Health has shown that your indoor climate has an enormous impact on your health. Too much CO2 in the air, for example, can cause headaches and fatigue. The risk of this happening is especially high in modernised, energy-efficient buildings, because their excellent insulation significantly reduces the exchange of air between inside and outside.

Another factor that could potentially harm your health as well as CO2 are air pollutants. Many furnishings such as pieces of furniture, floor coverings or wallpaper contain materials that can be harmful to health. Pollutants can also be released during cooking or by fireplaces, according to the study. So it is even more important to have a regular exchange of air in your home.

With Zehnder ventilation systems, you can say goodbye to thick, stale air in your home office: our systems control oxygen content and humidity automatically. And they remove pollutants too. So you can stay healthy and focus on your work properly.

2
Healthy air humidity in your home

The humidity of your indoor air should be in balance: An indoor climate that is too dry damages your skin and makes it permeable to viruses and bacteria. If, on the other hand, the air is too humid, mould will quickly form, causing lung diseases.

FAQ

FAQ

  • question_answerWhich ventilation system is right for me?

    The system you choose will depend on your budget and your property: we tend to recommend a central ventilation system for single-family homes, whereas a decentralised system is more suitable for smaller apartments or individual rooms.

  • question_answerI am an allergy sufferer. Is a home ventilation system suitable for me?

    Definitely – Zehnder ventilation systems are actually incredibly hypoallergenic. Extremely fine filters ensure that no pollen makes it inside the home. So you can breathe easy.

  • question_answerHow will a Zehnder ventilation system be good for my health?

    It's simple really: fresh air is extremely important for our bodies. For our organs to work perfectly, they need a good supply of oxygen. Ventilation systems save you the hassle of constantly opening your windows and doors. They also ensure that pollutants are either left outside or transported there.

  • question_answerHow can ventilation systems help in these times of coronavirus?

    Coronavirus has created a great deal of uncertainty. But one thing that is definite is this: comfortable indoor ventilation helps to reduce the number of virus particles in indoor settings and successfully convey the stale air outdoors.

    Operating purely as an outdoor air system, comfort ventilation provides a continuous supply of fresh, filtered outdoor air and distributes it around the different rooms in the building, thus rapidly diluting any contamination in the air. Stale and contaminated air is not re-used, it is all removed outdoors instead. Supply air ducts and extract air ducts are kept separate from one another.

    Find out more how balanced ventilation contributes to dilute virus particles indoors.

  • question_answerWhich filter class is suitable for my domestic ventilation?

    With filter class F (ISO ePM1), even the tiniest pollutant particles are left outside.

    Zehnder original filters are the best choice for your home. They always meet the latest standards and legal requirements.

    We recommend checking your filters regularly and replacing them in compliance with hygiene regulations as required.

  • question_answerWhat is the cost of residential ventilation?

    Home ventilation systems are available to suit every budget. The price will depend mainly on the size of the system. Click here to see all Zehnder ventilation systems.
