Proper Ventilation in Summer: How to Keep the Air in Your House or Apartment Fresh
Keeping indoor spaces pleasantly cool and fresh in summer is a challenge. With the following tips and strategies, you can ensure an optimal indoor climate, even as temperatures rise outside.
1. The Best Times to Ventilate in Summer
To avoid stuffy air in your home, you should ventilate at the right times:
- Ventilate in the morning and evening. Open the windows early in the morning or late in the evening, when it's coolest outside and outdoor temperatures are lower than indoor temperatures. This ensures a quick and effective air exchange.
- Avoid ventilating during the hot midday hours. During this time, warm air flows into the home and worsens the indoor climate.
2. Cross-Ventilation Ensures Optimal Air Exchange
One of the most effective methods to bring fresh air into rooms is cross-ventilation:
- Open windows on opposite sides. This creates a draft that exchanges the air faster.
- Leave doors open. This promotes air circulation between rooms.
3. Monitor Air Quality with the air quality monitor air-Q
Monitoring air quality helps determine the optimal time to ventilate. Use an air quality monitor such as the air-Q for this. This device measures relevant air components such as oxygen, CO₂, fine dust and other relevant indoor air parameters. This lets you ventilate in a data-driven and targeted way whenever air quality declines, ensuring consistently healthy indoor air.
4. Keep the Heat Out
To avoid unnecessarily heating up the rooms, you should take measures to keep the heat outside:
- Keep the windows closed during the day – especially during the hot hours.
- Close curtains and shutters. Dark curtains or closed shutters prevent the sun from heating up the rooms.
5. Use an Air Purifier
If you keep the windows closed during the day, air quality can decline quickly. Air purifiers can help here by cleaning stale indoor air. We tested what an air filter like the Briiv Air Filter can do. You'll find the results in our air-Q Lab "Briiv – The Most Sustainable Air Filter".
6. Additional Tips for a Better Indoor Climate in Summer
Besides ventilating, there are other measures that improve the indoor climate in summer:
- Add houseplants. Plants such as aloe vera or snake plant improve air quality by producing oxygen and filtering pollutants.
- Use humidifiers. Especially during very hot and dry periods, a humidifier can improve the indoor climate.
- Switch off unused electronic devices. Devices such as computers or TVs emit heat. Switch them off when they're not needed.
- Use air conditioning only in emergencies and always in combination with a humidifier. Otherwise, humidity drops rapidly, the air becomes dry, and this puts a strain on the mucous membranes. Dry mucous membranes offer favorable conditions for pathogens and weaken the body's own defenses.
With these strategies, you'll ensure fresh and pleasant air in your home even on hot summer days. Enjoy the summer without having to sacrifice comfort!
How to Effectively Avoid Stuffy Air in Summer
In summer, stuffy air indoors can quickly become a burden, especially as temperatures rise and humidity increases. Stuffy air often occurs when air exchange is insufficient and moisture, heat and pollutants accumulate in enclosed rooms. To avoid this, proper ventilation is crucial.
An effective way to avoid stuffy air is targeted burst ventilation. This means opening all windows wide several times a day to allow for a quick air exchange. It's best to ventilate in the morning and evening, when outdoor temperatures are lower and the air is fresher. This allows the warm, humid indoor air to escape and be replaced by cooler, drier outdoor air.
In addition to burst ventilation, using fans can also help improve air circulation and avoid stuffy air. Fans keep the air moving and reduce the buildup of moisture and heat. Make sure to position fans so they optimally move air throughout the room.
Another tip is to use dehumidifiers, especially in rooms with high humidity such as bathrooms or kitchens. Dehumidifiers reduce moisture in the air, which prevents the formation of stuffy air and makes the indoor climate more pleasant.
Additionally, you should make sure to switch off heat sources such as electronic devices or lighting that aren't needed. These contribute to warming the indoor air and can make it stuffier.
Through these measures, you can effectively avoid stuffy air in summer and ensure a more pleasant indoor climate. Regular ventilation and the targeted use of aids help improve air quality in your living spaces.

Tips for Effectively Freshening the Air in Your Home
In summer, we long for fresh, pleasant air in our living spaces. But often the air in the home can become stale and unpleasant. To be able to freshen the air, a few simple measures can help that significantly improve the indoor climate.
A proven approach to freshening the air in your home is regular ventilation. Open the windows wide to allow for a complete air exchange. This is especially effective in the morning and evening, when outdoor temperatures are cooler. This lets fresh, oxygen-rich air into the rooms and drives out stale air.
Plants are also an excellent way to freshen the air. Green plants such as the spider plant, snake plant or dragon tree filter pollutants from the air and increase the oxygen concentration. At the same time, they contribute to humidity, which can be especially beneficial during dry summer months.
Another tip is the use of essential oils. Use a diffuser to spread natural scents such as lavender, lemon or eucalyptus into the air. These oils not only have a pleasant scent but also a calming effect that boosts wellbeing.
Placing bowls of water with lemon slices can also help freshen the air. The lemon gives off a fresh scent, while the water slightly increases humidity, which can be very pleasant during dry summer months.
Additionally, you should make sure to clean regularly and remove dust, as it can impair air quality. Use natural cleaning products where possible to avoid releasing additional chemical substances into the air.
With these simple measures, you can freshen the air in your home and create a pleasant, healthy indoor climate. Regular ventilation, the use of plants and natural fragrances, as well as thorough cleaning, all contribute significantly to improving air quality in your home.
Air Purifiers Against Stuffy Air: How to Improve the Indoor Climate in Summer
In summer, stuffy air indoors can quickly become a burden, especially as temperatures rise and humidity increases. An air purifier against stuffy air can offer an effective solution here to improve the indoor climate and ensure fresh air.
Air purifiers work by filtering pollutants, dust particles and unpleasant odors out of the air. Models with HEPA filters are particularly effective, as they remove even the smallest particles and allergens from the air. This is especially important in enclosed rooms, where air exchange is limited and pollutants can accumulate quickly.
Besides cleaning the air, air purifiers can also help regulate humidity, which is crucial to avoiding stuffy air. Some devices feature built-in humidifiers or dehumidifiers that further optimize the indoor climate.
To achieve the best effect, you should place the air purifier strategically in the room, ideally near areas where people spend a lot of time. Be sure to change the filters regularly to ensure the device's efficiency.
In addition, the air purifier helps create a healthy indoor climate that boosts wellbeing and relieves the airways. Especially during the summer months, when air quality is affected by high temperatures and pollen exposure, an air purifier provides valuable support.
Incorporate an air purifier into your summer strategy for improving air quality to effectively combat stuffy air and create a pleasant living environment.
