The indoor environment is believed to be more polluted than the outdoor air. Given that pretty much everyone spend more time indoors instead of outdoors, they end up with drastic allergies and asthma. Indoor smoking is 1 of the most usual ways of compromising air quality. The Residues from cigarettes settle on fabrics inside the house, posing a risk to children and those with heart and lung problems! Electronic cigarettes also leave traces of Volatile Organic Compounds(VOCs), which are also harmful to your health. Household cleaning products also lower your air quality. This is because they have drastic chemicals that emit fumes that irritate your mouth, nose, skin, and lungs. Humidity levels in the house should be at an optimal level, as low humidity levels increase dryness of skin, rashes, eye irritations, and dry nose. When the humidity levels are in excess, water condenses onto icy surfaces to cause mold growth and increase dust mites. Using gas stoves also produces carbon dioxide and particulates, thus affecting those using them for cooking. Synthetic floorings also cause bad air quality because of the VOCs being released from vinyl flooring. Air purifiers should prevent these VOCs from being inhaled. As much as plants are hailed to be great air cleaners, you should check the soil to see if there is mold growth around them as plants produce moisture favorable for mold growth. You can also use air filtration to prevent mold growth; Fiberglass used in building insulations is also a source of Volatile organic compounds at home. It is best to groom your pets annually, stop using gas stoves, stop smoking, and officially change your air filters.
