The perfect indoor climate – for more energy, better concentration and a great mood.

The climate and air quality that prevail in enclosed spaces have an enormous impact on how we feel. If the air is fresh, our minds are too. Oxygen-rich indoor air at a well-balanced temperature improves our concentration and our productivity. We sleep better, are more cheerful and feel full of vim and vigour. Zehnder room ventilation systems are designed to create exactly this perfect indoor climate – and they do it automatically, without you even noticing. They are really energy-saving too, which is guaranteed to put you in an even better mood!

Better concentration

Fresh air makes it easier to think. Studies have shown that the more often you ventilate your surroundings, the better you perform. So it’s a great way to reduce stress and stay healthy.

More energy

Our domestic ventilation provides you with a constant supply of fresh air and renewed energy. So not only will you hit rush hour full steam ahead, you will still have lots of energy to spend hours messing about with the kids once your work is done.

Better sleep, more vitality

We should actually ventilate our bedrooms every two hours during the night to keep CO2 levels low and have a restful sleep. Our domestic ventilation does that for you automatically – while you just sleep through it. And that is good for your health, since restful sleep is essential for a strong immune system.

Better mood

A good mood comes free of charge with our ventilation systems. A study has shown that school pupils are much happier if they have fresh air – which will be a relief for any stressed-out parents dealing with home schooling at the moment.

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.

How Zehnder ventilation systems work in your home

How Zehnder ventilation systems work in your home

1. The unit takes in outdoor air.

2. The air taken in by the unit is filtered. Pollen and fine particulate matter are left outside.

3. Pipes in the walls, ceilings or floors distribute the fresh air throughout the whole home.

4. Heat recovery ensures that heat from the stale air is retained inside the home as required.

5. Humidity recovery ensures that humidity is retained inside the home as required. This process prevents the indoor air from getting too dry, especially in winter.

6. If the temperature soars during summer, the optional enthalpy exchanger can remove heat and humidity from the warm, humid outdoor air before the fresh air enters the home.

7. This way, your home will always have the best indoor climate.

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.
