and mold spores. Allergens can trigger asthma, allergies, and other
respiratory conditions.
-
Smoke: Smoke from cigarettes, fireplaces, and cooking can
contain various toxins and carcinogens, which pose a risk to lung health.
-
Bacteria and Viruses: Airborne pathogens like bacteria
and viruses can spread diseases, making air purification important for
maintaining a healthy environment.
How Indoor Air Quality Impacts Health
Poor indoor air quality has both short-term and long-term health effects,
ranging from minor irritations like eye, nose, and throat discomfort to
serious conditions like asthma, heart disease, and respiratory infections. For
those with pre-existing respiratory or cardiovascular conditions, exposure to
indoor pollutants can worsen symptoms, affecting their quality of life. Clean
air is vital to prevent these adverse effects, and air purifiers play a
significant role in improving indoor air quality.
Role of Air Purifiers in Improving Air Quality
Air purifiers filter out harmful particles and pollutants from indoor air.
They use specialized filters such as HEPA (High-Efficiency Particulate Air)
filters to capture particles as small as 0.3 microns and carbon filters to
neutralize odors and VOCs. Air purifiers constantly filter the air, reducing
the levels of contaminants and creating a healthier indoor environment.
Key Features to Consider When Choosing an Air Purifier
When buying an air purifier for your home, here’s what you should look for: Choosing the Right Air Purifier in India: Everything You Need to Know!
Room Size and Coverage Area
The first step in selecting an air purifier is determining the size of the
room where it will be used. Each air purifier is designed to clean a specific
area efficiently. Here’s a breakdown of typical coverage recommendations:
