The working principle of an air purifier:
  The motor and fan inside the machine make the indoor air circulate. Polluted air passes through the air filter in the machine and various pollutants are removed or adsorbed. Some types of air purifiers also install a negative ion generator at the outlet (during operation, the negative ion generator generates a high voltage that produces a direct current negative high voltage), ionizing the air continuously and generating many negative ions. These negative ions are sent out by the small fan, forming a negative ion airflow, achieving the purpose of cleaning and purifying the air. It is mainly composed of a motor, a fan, an air filter, etc.
  Although the names, types, and functions of air purifiers advertised in the market vary, when traced back to their origins, the working principles of various air purifiers mainly fall into three types: forced, automatic, and main forced-mixed.
  Among them: The main principle of a forced air purifier: The fan sucks air into the machine, and the air is filtered by the built-in filter. Its main effect is to filter dust, odors, toxic gases, and kill some bacteria. The principle of an automatic air purifier differs fundamentally from that of the forced air purifier. Unlike the forced air purifier, which waits passively for the indoor air to be sucked into the purifier for filtration and purification, the automatic air purifier effectively and automatically releases purification and sterilization factors into the air, through the characteristic of air dispersion, to purify the air in every corner of the room. The two-layer purifiers are originally a combination of forced purification technology and automatic purification technology.
The above three purification principles are the most widely used and common air purifiers in the current market.

  Features of air purifiers:
  Air purifiers are one of the most important purification devices in the purification field. We have evolved from simple protective tools in the past to today's capable of purifying allergens, asthma triggers, viruses, bacteria, harmful gases, and other airborne substances. Our requirements for environmental protection and product quality are getting higher and higher. Air purifiers have already become a necessary purification device in today's life.
  The appearance of air purifiers and commercial purifiers is very different. The main difference lies in their functions and parameters. However, many customers do not have such professional knowledge, so they often waste a lot of resources during the purchasing process. Now let's grasp the following characteristics for choosing an appropriate household air purifier:
  In terms of function, air purifiers adhere to traditional technology and manufacturing methods, and the raw materials of the filter have not changed. The air intake and exhaust design adopts the method of side intake and side exhaust. The motor uses a German original imported EBM fan, with large air volume and low noise. Whether it is during rest at night or normal work, it can quietly purify every corner of your space. At the same time, the machine's power is the highest only 70W. Even if you operate at the maximum speed for 24 hours, the energy consumption is less than 2 degrees of electricity. The noise is the lowest only 32 decibels. It is truly high efficiency, low energy consumption, and low noise.
  Air purifiers have strong oxidation functions, allowing toxic components in the air to undergo chemical oxidation-reduction reactions. After the reaction, harmless gases such as hydrogen and nitrogen, carbon dioxide, etc. are released, improving the previous situation where air purifiers only had the method of absorbing harmful gases. It opens up a new situation for air purification.
  Disinfection, deodorization, and removal of formaldehyde and other harmful gases: The traditional method of releasing ozone (also known as active oxygen) is to use an ozone glass tube under high frequency and high voltage to release ozone. This method is simple in technology, but the lifespan of the ozone glass tube is short, only 1,500 hours; the current company's products release ozone using stainless steel guides and alloy needles under direct current negative high voltage, and the released ozone volume is higher than the international standard by 0.04 ppm. Scientific verification shows that ozone has strong oxidizing and sterilizing functions. When we are in the seaside or in forests, the ozone concentration is above 0.04 ppm, giving us a refreshing feeling.
  The raw materials of the filter core of the purifier neither stretch nor shrink, nor expand or contract. The effect is the same as that of the pulse. The lifespan of the filter core is extended, and the steel structure is sturdy and durable. The energy-saving modification of the purifier's shell remains unchanged. The electricity-saving value of using it for one and a half years can recover all the modification costs. The new system can recover all the investment after three years of use. When purchasing an air purifier, we need to think carefully. We can refer to the top ten brands of air purifiers for a reasonable purchase. Do not be greedy for small benefits. Do not buy goods of poor quality.
