The quality of the air we breathe at home influences our health, our rest and our daily well being much more than we think. We spend between 80 to 90 % of our time in closed spaces, and yet we rarely stop to think if the air in our home is really clean.
Dust, humidity, cleaning products, bad habits or insufficient ventilation can deteriorate air quality at home without us being aware. The good news is that improving air quality is possible, does not require large investments and has a direct impact on our health and on the sustainability of the home. Let us see how to improve air quality at home.
What are the symptoms of poor air quality in your home?
One of the main problems of poor indoor air quality is that it is not always seen, but it is felt. Many people live with contaminated air at home without relating certain symptoms to their real origin. Some of the most common signs of poor air quality at home are:
- Frequent headaches without apparent cause
- Feeling of constant tiredness or lack of concentration
- Irritation of eyes, nose or throat
- Persistent nasal congestion
- Dry cough or mild respiratory problems
- Worsening of allergies or asthma
- Excessive dryness or, on the contrary, feeling of a heavy environment
- Bad odors that remain even after cleaning
In children, the elderly or people with respiratory problems, these symptoms can intensify. Therefore, improving air quality is not just a matter of comfort, but of preventing something that can worsen your health.
Ways to measure air quality at home
Before applying solutions, it is advisable to understand what is really happening in the indoor environment. Today there are several ways to measure air quality at home, from simple methods to more advanced systems.
Air quality sensors and meters
Domestic air quality meters allow knowing data such as the CO2 level, relative humidity, temperature, presence of suspended particles (PM2.5 and PM10) or volatile organic compounds (VOCs). These devices help identify patterns, such as poor ventilation or excess humidity, and are especially useful if you live in urban areas or in poorly ventilated homes.
Observation of the environment
Although it is not a technical method, observing certain aspects of the home also provides clear clues:
- Frequent condensation on windows
- Appearance of mold in corners or ceilings
- Stale smell when entering the house
- Feeling of heavy or loaded air
Tips to improve air quality
1. Ventilation
Ventilation is the fundamental pillar to improve air quality at home. Renewing indoor air allows removing pollutants, reducing CO2 concentration and regulating humidity.
Ideally, ventilate at least 10 to 15 minutes a day, even in winter. If you can, do it by creating cross ventilation, opening opposite windows to favor air circulation. We advise you:
- Ventilate early in the morning or late at night if you live in areas with heavy traffic
- Avoid ventilating during peak hours of pollution
- Always ventilate after cooking, showering or cleaning.
2. Humidity
Humidity is a key and often ignored factor. Both an excess and a deficit can harm air quality at home. It should be between 40 to 60%. Less than 40 would already be too dry air, irritation of mucous membranes, while with more than 60 % there would already be a risk of mold, mites and fungi. To achieve this:
- Use dehumidifiers in humid areas
- Avoid drying clothes inside the house without ventilating
- Use humidifiers if the environment is very dry
- Control humidity with a hygrometer
3. Cleaning and products
Cleaning also directly influences air quality at home, but not always in the way we imagine. Many conventional cleaning products release chemicals that remain in the air for hours.
To improve air quality do not use aerosols or artificial air fresheners, prioritizing ecological or natural products and using vinegar, baking soda or neutral soap to clean when possible. In addition, it is important to maintain regular cleaning of carpets, curtains, sofas and textiles and vacuum cleaner filters. Accumulated dust acts as a reservoir of pollutants and directly affects air quality.
4. Purifiers and HVAC
In certain cases, especially in urban homes or with respiratory problems, air purifiers can be a great ally. Purifiers with HEPA filters help reduce fine particles, remove pollen and allergens and decrease the load of suspended pollutants.
On the other hand, HVAC systems (heating, ventilation and air conditioning) must be maintained correctly, as a poorly cared for system can worsen air quality instead of improving it. Therefore you should clean or change the filters periodically, checking the ducts and air outlets and, if it is an old system and also poorly maintained, better change it for a new one.
5. Plants
Plants not only decorate, they also contribute to creating a healthier environment. Although they do not replace ventilation, they do help improve air quality at home and provide psychological well being. Some plants we recommend are:
- Pothos. Very resistant and easy to care for, helps reduce common pollutants and improves the feeling of freshness in the environment.
- Ivy. Ideal for interiors, especially in areas with humidity. Contributes to reducing suspended particles.
- Aloe vera. In addition to its medicinal properties, it is a plant that helps improve air quality and requires little maintenance. Placing several plants spread throughout the home contributes to a more natural and healthy environment.
Sources of pollution to avoid to improve air quality
As important as applying solutions is avoiding indoor pollution sources. Some of the most common are:
- Tobacco smoke
- Scented candles and synthetic air fresheners
- Cooking without extractor or ventilation
- Paints and varnishes with solvents
- New furniture without prior ventilation
- Excessive use of insecticides
Conclusion: Improving air quality at home is health
Air quality at home is not a luxury or a fad, it is a matter of health, well being and sustainability. Small daily gestures such as ventilating, controlling humidity, choosing suitable products or introducing plants can make a huge difference.
Improving air quality not only reduces physical symptoms, but also improves rest, concentration and quality of life. A home with clean air is a healthier home and more aware of its environment. If you are interested in sustainability applied to daily life, starting by improving air quality at home is one of the easiest and most effective steps you can take. Breathing better is living better.
