Harvard University professor and director of the Harvard Healthy Building Program Joseph Allen, D.Sc., MPH, states: “The people who design, operate, and maintain our buildings have a bigger impact on our health than our doctors.” That explain the importance of indoor air quality.

Therefore, architects who design our homes and interiors should prioritize solutions to improve indoor air quality. Air makes up 90% of every home’s interior. If you’re lucky enough to live to be 80, you’ll spend 55 years in your home, breathing 8,250 litres of air daily.

Although we all want to believe the air in our homes is of good quality, unfortunately, this is mostly not true, according to the Environmental Protection Agency (EPA, indoor air is usually 3-5 times more polluted than outdoor air, and access to healthy and quality outdoor air is a luxury that less than 1% of today’s world population has, according to the World Health Organization (WHO.

Therefore, the air we breathe in a closed space directly affects our health and well-being. Invest in a healthier, happier home by taking these steps to maintain clean indoor air quality.

What you can do to ensure a healthier and happier environment for yourself and your family can be read in detail in a recently published article on our LinkedIn profile, and the following are brief guidelines:

🧹 Clean your home thoroughly

Good indoor hygiene is fundamental to clean indoor air.

🚫 Throw away products that contain harmful and dangerous substances

Avoid equipment, furniture, and hygiene products that harm indoor air quality. Choose eco-friendly methods for maintaining hygiene instead of chemical-based ones.

🌧️ Pay attention to moisture and mould

Moisture is the basis for mould creation, which is dangerous to your health.

🌷 Choose your indoor plants wisely

Indoor plants can improve indoor air quality and user comfort, but care should be taken when selecting them, as some species can trigger allergic reactions.

🪟 Ventilate your home

Ventilation is crucial for good indoor air quality, but be mindful of outdoor air pollution and related health recommendations.

🛠️ Maintaining your HVAC system is essential

If you have a centralized ventilation system, do not skip the recommended service activities, as they help ensure system efficiency and prevent indoor air quality issues.

🍃 Regular replacement of the air filter

Replace all air filters in your home regularly. Do not forget those for a central ventilation system, a kitchen hood, a home air purifier, or a room air conditioner. If possible, increase the filtration class in use.

🕯️ Avoid candles and air fresheners

All activities that emit volatile organic compounds (VOCs) in the space, and any open flame, should be avoided.

🫕Be careful in the kitchen

Use stoves that reduce emissions (see our previous posts for more). Frying food less and boiling or cooking it more are better for your health and emit fewer airborne particles.
