    Air pollution has a pronounced negative impact on human health and is bad news for everyone's health. The increased amount of airborne pollutants can:

    1. Irritate lungs and throat, making breathing hard. 
    2. Coughing, difficulty breathing, or eye irritation.
    3. Increase risks of asthma, bronchitis, and heart issues.
    4. Introduce harmful particles deep into our lungs.
    5. Weaken the immune system.
    6. Potentially shorten our lifespan.

    And bad air quality is especially detrimental for these individuals who are allergic to pollutants. 

    Allergies are specific reactions of the body's immune system to substances. When someone with an allergy encounters their specific allergen, their immune system reacts and trigger allergy symptoms, leading to symptoms like itching, rashes, or even anaphylaxis in severe cases. For instance, someone with an allergy to pollen would have hay fever during high pollen seasons.

    The most common air pollutant allergic symptom is allergic rhinitis – when the air's bad, some folks can't stop sneezing, get a leaky nose, and look like they've just watched a sad movie marathon.  

    LUFTQI has pioneered the application of photocatalytic purification technology in portable air purifiers. Since its introduction, many users who tried it, especially the ones super sensitive to air, say they're feeling a whole lot better with these purifiers around.

    LUFTQI understands that people also need solid evidence to be convinced, so it has conducted experiments to provide concrete proof of the claims.

    To validate the efficacy of LUFT Photocatalytic Air Purifiers Combating Environmental Allergens, a series of animal tests were conducted in collaboration with the Department of Biotechnology at Chung Yuan Christian University.

    Experimental Design and Method

    To understand the improvement in allergic symptoms caused by pollen and PM2.5 by air purifiers. Three groups of Male Sprague-Dawley (SD) rats were put in the sealed chambers to observe breathing rate, asthma incidents, and sleep duration.

    1. Control group: Breathed normal air
    2. Photocatalytic purification group: Breathed polluted air with photocatalytic air purifiers working in the chamber. 
    3. Without purification group: Breathed polluted air without air purifiers.

    The airborne pollutants used were pollen (Japanese Cedar) and PM2.5 particles (diesel engine particle standard CRM558). These are common allergy inducers in the air.  




    There were positive results for the performance of LUFT air purifiers.

    • Breathing Rate: The rats in the photocatalytic purification group showed a significantly reduced breathing rate, similar to the control group that breathed normal air, indicating the purifier's effectiveness in alleviating respiratory allergy symptoms.
    • Asthma Incidents: The number of asthma incidents in the photocatalytic group was noticeably lower, similar to the control group that breathed normal air. This suggests the purifier can mitigate allergic asthma symptoms.
    • Sleep Duration: Sleep duration in the photocatalytic group improved significantly compared to the group without purification, similar to the control group that breathed normal air. 

    Just as avoiding an allergenic food can prevent allergic reactions, eliminating airborne allergens can greatly help those sensitive to them and enhance their quality of life. The experiment results show that LUFT photocatalytic air purifiers effectively alleviate allergic conditions like rhinitis and asthma. Beyond assisting those sensitive to air, the purifier's applications include:

    • Reducing second-hand smoke's impact on others.
    • Eliminating indoor odors (like post-cooking fumes and pet smells).
    • Decreasing indoor suspended particles lowers infection transmission risks.

    In essence, LUFT air purifiers have achieved significant results in purifying air, improving allergy symptoms, and enhancing quality of life, and are anticipated to play an even larger role in future air quality improvement initiatives.
