      Over 90% of small air purifiers on the market are of the negative ion type. They are popular due to their compact size and cost-effectiveness. However, their effectiveness in truly purifying the air has been a topic of debate. The main principle behind negative ion air purifiers is that they release a stream of negative ions into the air, which then bond with positively charged particles such as dust, pollen, smoke, and other allergens, forming larger particles.

      While this process sounds promising, it has a significant drawback. The negative ion purifiers do not eliminate these larger particles; instead, they fall onto the surfaces around the purifier, such as walls, ceilings, and furniture, due to their increased weight. This phenomenon is often referred to as the "Black Wall Effect".

      While the air may appear cleaner because these particles are no longer suspended in it, they are still present in the environment and can be stirred back into the air with any disturbance, like walking by or turning on a fan. This process could potentially lead to secondary pollution.

      Since the range of negative ion emission is limited, most of them cover only about 20 cm around the device. As a result, you'll notice a lot of dust accumulation around the device. These fallen particles create a layer of dust around the device, requiring regular cleaning of the surrounding areas. Hence, negative ion purifiers are not truly cleaning the air but merely displacing particles.

      In contrast, LUFTQI utilizes Photocatalytic Oxidation to provide genuine air purification, capturing and neutralizing harmful particles in the air. With the Duo model, LUFTQI further utilizes the bonding characteristics of negative ions to create an excellent dust collection design. Through the use of an intake fan, the dust is concentrated and properly contained within the machine itself.

      Since the advent of photocatalytic technology, it has been commonly used in the air conditioning ducts of medical institutions as a sterilization technique.

      LUFTQI is the first to miniaturize this photocatalytic purification technology into a small air purifier. Since beginning product development, LUFTQI has invested substantial resources in conducting various pathogens elimination tests through third-party testing institutions, such as SGS and SuperLab.

      As for the coronavirus that caused the pandemic, LUFTQI also commissioned a well-known domestic scholar who studies bat coronaviruses to verify the effectiveness of SPP Nanotech in neutralizing the coronavirus. Due to biosafety considerations and regulations, the test was conducted using feline coronaviruses. Since the characteristics of all coronaviruses are similar, the inactivation tests are proven effective.

      The LUFTQI team collaborated with the Industrial Technology Research Institute in Taiwan to conduct field tests in a bronchoscopy room within a medical institution, verifying the efficacy of their device in eliminating various types of bacteria and odors in that setting.

      In 2021, the LUFT Duo received the SNQ(Symbol of National Quality) epidemic prevention product certification, showcasing LUFTQI's robust capabilities.

      LUFTQI uses a UVA LED light source to stimulate the photocatalyst. The design ensures that most UV light energy is contained within the reaction chamber. Any minor leakage of UV light undergoes multiple refractions, and the energy released is significantly lower than exposure to the summer sun for one minute. Thus, it will not pose any risk to human health. However, looking closely into the device with your eyes is not recommended.

      Theoretically, the photocatalyst does not deplete. However, in practical applications, the efficiency of the photocatalyst can be diminished by the numerous dust particles in the air that coat the photocatalyst's surface, thereby reducing its effectiveness over time.

      LUFTQI has considered this in its design and optimized the system accordingly. The continuously rotating magnetic levitation fan is the main factor limiting the LUFT air purifier's lifespan. Its Mean Time Between Failures (MTBF) is designed for 40,000 hours If used 24/7, that is equal to 1667 days.

      LUFT air purifiers employ a stainless steel antibacterial filter. Depending on the air pollution conditions in your environment, it needs to be cleaned every one to three months! There's no need to replace consumables, eco-friendly and cost-effective.

      *Please be noted that the machine body should not be rinsed directly with water.

      Allergy symptoms result from an overreaction by the human immune system to foreign environmental substances. Diluting the allergens that cause immune responses usually improves allergy symptoms.

      LUFT uses the hydroxyl radicals and superoxide ions derived from the energy conversion of photocatalysts to break and degrade organic substances. For individuals sensitive to air quality, LUFT continuously degrades allergens in the air in areas where you spend a lot of time (such as sleeping areas, offices, cars, etc.). Delivering the purified air close to the respiratory system help people who suffer from allergies.

      LUFTQI team has further cooperated with the laboratory of the Department of Biotechnology at Chung Yuan Christian University to conduct animal experiments to confirm: LUFTQI's experimental group improved the research results of asthma induced by 40% of allergens.

      Many people feel that small air purifiers should come with batteries. To clarify, none of the LUFT series include a battery and requires no charging. Therefore, when using LUFT air purifiers, you must plug them into an external USB power source (recommend 5V/2A or above) to keep them running. If you need to carry the air purifiers out, you can get portable power banks and use them together.

      Among various purification technologies, photocatalytic tech stands out for odor removal. LUFTQI's patented SPP Nanotech enables noticeable odor removal, which has been highly praised. If you have food smells, cigarette smoke, musty smells, cooking fumes, pet odors, etc., lingering in the space, LUFT can handle all of them.

      We all have noses that are more sensitive than sensors. Run LUFT air purifiers in places with a strong smell, such as in a car, bathroom, or bedroom with stagnant air that has a musty or smoky smell for ten minutes, you will clearly feel the improvement of air quality.

      If you intend to use LUFT air purifiers for personal protection, LUFT is not restricted by space sizes. LUFT Cube and Duo both come with a wind guide cap and can deliver clean air directly to your nose for breathing. As long as you stay in the airflow range, you can always be protected from pollutants.

      If you want to use LUFT air purifiers for odors removal, a LUFT Cube can provide good performance in areas no larger than 16.5m2 (178ft²), such as in a car, bathroom, or small room, and a LUFT Duo can work decently in spaces no larger than 22.3m2 (240ft²), such as in a living room, dining room, or the office meeting room. For larger spaces, it is recommended to use multiple LUFT air purifiers to get optimal results.
