Pain point 1: Air measurement is inaccurate. The accuracy of air quality detection is crucial to the operation of air purifiers. There are currently several types of air dust sensors, with large differences in accuracy and cost. Moreover, the location of integration into the fuselage is also particular. Products with insufficient technical accumulation can easily misjudge the cleanliness of the air. Most of those air purifiers that can only roughly judge the air quality use cheap infrared sensors.
LIFAair takes a unique approach in air detection. Its products are all equipped with separate independent air detectors, and are designed to integrate multiple sensors. They can not only detect PM2.5 air dust, but also It can display formaldehyde, carbon dioxide concentration, etc., which allows users and purifiers to know the air conditions where the detector is located at any time, which is a qualitative improvement compared to a single detector integrated on the fuselage. Coupled with intelligent algorithms, the LIFAair air purifier can operate more accurately to prevent the purifier from being surprised and interfering with the user's life and rest.
Pain point 2: Purification speed and effect. The filter element is the core component of the air purifier, and its technology directly determines the purification effect of the air purifier. At present, many thousand-yuan air purifiers use HEPA+activated carbon filter element solutions. Most of the filter elements are directly imported from suppliers. The level of filter element purchased by the manufacturer directly determines the purification effect. The purification effect of the HEPA filter is pretty good, but the disadvantage is that the life of the HEPA filter is limited and needs to be replaced frequently.
LIFAair is taking the "stupid" path of independently developing filter elements. The technology called 3G filter has applied for a global patent. 3G filtering is a complex of multiple filtering technologies, including 7-level filtration. : Primary filter that intercepts fibers (PM10.0) and some oil fumes, ultraviolet disinfection device, air ionization system, loose and powerful charged electret filter material, special activated carbon composite absorption layer, opposite polarity to the front-end ionization system High-pressure holding layer and second-stage activated carbon filter.
These 7 filters can block extremely small particles with a diameter of 0.006 microns, including cooking smells, smoking odors, and viruses in the air, which can be filtered at once. This is why Finland’s ambulances and military battlefield nuclear, biological and chemical protection all use LIFAair 3G filtration technology.
We can see the huge difference between 3G filtration technology and HEPA filter elements - using a more active charge capture method and ultraviolet sterilization solution, on the premise of having a more comprehensive filtration effect, the 3G filter element can It has a huge dust holding capacity, which greatly extends the life of the filter element. According to official data, the dust holding capacity of the 3G filter element is more than 2 orders of magnitude higher than that of the HEPA filter, which means that the time to replace the filter element has changed from months to years. count.
In addition, LIFAair's flagship product LAF500 fresh air air purifier is also quite unique - it combines the fresh air system and air purification into one, filtering the outdoor air and actively inputting it into the room to improve the indoor air pressure. It is always higher than the outside, thereby squeezing out the indoor turbid air through the cracks in doors and windows, so that the dirty air and dust outside have no opportunity to take advantage of it. This is an important development direction for household air purifiers in the future, because in the north where smog is frequent, although traditional air purifiers can filter indoor air, they cannot open windows for ventilation for too long, which will also lead to increased indoor carbon dioxide concentration and other problems. . The fresh air air purifier does not require opening the window for ventilation, which will obviously provide a better comfort experience.
Pain point 3: Too much noise. The principle of most air purifiers is not complicated, fan + filter element, it is not difficult to implement, which can also explain why there will be hundreds of new air purifier manufacturers in 2014-2015. This is a bit like building a car. It looks like it has four wheels and two sofas. The core components of the engine can also be imported. However, to achieve a high user experience is a project that tests the technology and design background.
For air purifier manufacturers with insufficient technical accumulation, it is difficult to solve the problems of body resonance and wind noise alone. This requires rich experience and powerful computer-aided design. Advanced companies will even have specialized Noise laboratory to study airflow noise issues. It is difficult to understand the noise problem intuitively from the parameters marked by the manufacturer. You can only believe it by hearing it. Therefore, when purchasing, you should preferably choose a brand with historical technology accumulation and reputation.
Generally speaking, LIFAair’s greatest honor is its core technology, which is why LIFAair is confident enough to be the “dragon that crosses the river”. In addition to the fresh air purifier LAF500, LIFAair's other two popular household air purifiers LA500 & LA300 also have technical features. The parallel filter element structure can prevent secondary pollution of the air outlet by granular activated carbon and enhance the life of the HEPA filter. , and is equipped with a 3.5kg activated carbon barrel and an H12-level HEPA filter element. The CARD values ??are 450m?/h and 350m?/h respectively, and both use ultra-quiet fans. After the air detection, purification effect and noise problems have all been solved, it can be expected that as long as the pricing strategy is appropriate, LIFAair's market competitiveness will still be strong.
