Essential Reasons Why Air Purifiers Are a Must for Cleaner Living Environment

According to a study shared by the Environmental International, allergic diseases are often linked to indoor air pollution, including dust, pet dander, and other common allergens. These pollutants can worsen asthma, allergies, and respiratory conditions by triggering inflammation in the airways.

Types of harmful pollutants in the air (ranked in order):

  1. Particulate Matter -like dust, dirt or smoke

    Particulate matter are harmful pollutants that can irritate the eyes, nose, and throat, and cause respiratory issues like asthma. The smallest particles can enter the lungs and bloodstream, increasing the risk of heart attacks, strokes, and reducing life expectancy. Long-term exposure poses serious health risks.


  2. Pet Dander

    Pet dander, the microscopic flakes of skin shed by animals, can trigger allergies and worsen asthma symptoms. It spreads easily through homes and public places, causing sneezing, runny noses, itchy eyes, and nasal congestion.


  3. Pollen

    Pollen, a common trigger of seasonal allergies, is released by plants to fertilize others. Once airborne, it can irritate the respiratory system, causing allergic reactions like sneezing, runny nose, and nasal congestion. Tree, grass, and weed pollens, such as ragweed, are the main culprits for these symptoms.


  4. Mold Spores

    Mold spores can become airborne and, when inhaled, can trigger allergic reactions, respiratory issues, and even infections, especially in individuals with weakened immune systems. Some molds, like black mold, can also produce toxins that are harmful to both humans and animals.


  5. VOCS

    Volatile Organic Compounds (VOCs) are gases from household items like paints, cleaners, and air fresheners. They can cause irritation, headaches, and nausea, and long-term exposure may lead to liver damage, fatigue, allergic reactions, and cancer.


In summary, air pollutants like particulate matter, pet dander, pollen, mold spores, and volatile organic compounds (VOCs) can cause various health issues, including respiratory problems, allergies, and long-term diseases. These pollutants can lead to irritation, congestion, and fatigue, affecting sleep quality and overall energy levels.


Benefits of having an air purifier:

  1. Relieves Symptoms of Asthma

    Helps by removing airborne allergens like pollen, pet dander, and dust mites. Their HEPA filters trap these particles, reducing irritation and preventing asthma attacks, leading to cleaner, healthier air.


  2. Eliminates Harmful Chemicals

    Air purifiers remove harmful chemicals from outdoor pollution and cleaning products. HEPA filters reduce outdoor pollution indoors, while activated carbon filters eliminate toxic chemicals, helping to reduce health risks.


  3. Neutralizes Unpleasant Odors

    Air purifiers with HEPA and activated carbon filters capture VOCs and odors from sources like paints, cooking, and sweat, improving air quality and keeping your space fresh and clean.


  4. Reduces the Chances of Airborne Diseases

    Air purifiers with HEPA filters capture airborne pathogens like flu viruses, reducing illness risk, especially for families with children, the elderly, or those with weakened immune systems.


  5. Reduces airborne mold spores

    Mold releases spores into the air that can spread throughout the home, including the bedroom. Air purifiers with HEPA filters capture these spores, preventing their circulation and reducing mold growth on surfaces.


How does an air purifier work?

Air purifier helps to remove particles from the air that circulates in your home providing cleaner, healthier air and reducing the risk of allergies and respiratory issues.


How often should I change the filter in my air purifier?

It depends on usage, but generally, HEPA filters should be replaced every 9–12 months.


How do I know which air purifier is right for me?
