What if the air we breathe every day is threatening our health? While air pollution is mainly thought to be caused by external factors such as cars and factories, surprisingly, indoor air can be up to 10 times more polluted than outdoor air. There are even statistics indicating that this causes 4 million deaths worldwide each year. Especially as the weather gets colder and ventilation decreases, we will explore ways to eliminate factors that worsen indoor air quality and maintain healthy air.

The easiest first step is ventilation.

Introducing fresh air into the house is the most important step to improve indoor air quality. Well-heated and well-insulated homes tend to have less external air inflow, making ventilation easier to overlook. Even in winter, opening the windows for just 10 minutes to bring in fresh air and prevent bacteria and mold growth is essential. Especially when using strong chemical cleaners or painting, proper ventilation must be ensured. According to Harvard University research, replacing furniture containing harmful substances with healthy material furniture can reduce toxic dust in the air by 78%. When purchasing new furniture, thorough ventilation is recommended, and using second-hand furniture is also a good option.

Use of cleaning products without chemical ingredients

Cleaning is important for maintaining health, but some cleaning products can actually harm health. Many household detergents contain volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). These can cause △headaches △allergies △respiratory problems and may lead to lung cancer, brain disorders, and cardiovascular diseases in the long term. Even 'eco-friendly' products should be carefully checked for ingredients, as some still contain harmful substances. Experts recommend using databases like CPISI (Cleaning Product Ingredient Safety Initiative) that verify ingredient safety before purchasing.

 

 

Air purifier installation

No matter how thoroughly you clean, it is difficult to remove ultrafine dust that is invisible to the naked eye. Air purifiers filter out these ultrafine particles and circulate clean air. They are especially effective in households with allergy sufferers or pets. Air purifiers equipped with HEPA filters remove 99.97% of ultrafine particles, and those with ion emission functions also help neutralize viruses and bacteria. Using an appropriate air purifier is effective in alleviating symptoms of respiratory diseases such as asthma and allergies.

They say it's not good to always close the door tightly just because it's cold.

When the afternoon sunlight is nice, also ventilate the house a bit.

The office is also leaving the water open for a short while.
