Air purifier improves indoor environment and prevents indoor air sub-health.air purifier covid compa

　　At present, there are nearly 2 million excess deaths in developing countries that may be caused by indoor air pollution, and about 4% of global diseases are related to the indoor environment. Monitoring data from our country also shows that the number of deaths caused by indoor air pollution in our country every year is also staggering. The air purifier improves the indoor environment and prevents sub-healthy indoor air.

　　Relevant data show that the main sources of indoor pollution are as follows: ① Human body. When people breathe, they need to inhale air, oxygen is taken in the alveoli, and then discharged containing high-concentration carbon dioxide and other toxic and harmful gases. ②Interior decoration. Decoration pollution has gradually become an important factor that seriously affects people's health in recent years. Among them, the harm of formaldehyde gas produced by indoor decoration to the human body has attracted increasing attention; ③Household appliances. Surveys in some countries have shown that people who have been in air-conditioned rooms for a long time are prone to symptoms such as dry respiratory tract, nasal congestion, and joint soreness in an environment with suitable temperature and humidity. At the same time, chest tightness, suffocation, lack of concentration, and fatigue are easy. Once you leave the air-conditioned room, after one or two days of adaptation, these symptoms will gradually disappear. People usually call this "air-conditioning syndrome"; ④ life exhaust gas. People indoor activities and eating and drinking Lazard will produce abnormal gases, which are also sources of indoor pollution. The air purifier improves the indoor environment and prevents sub-healthy indoor air.

　　Due to the large differences in indoor and outdoor temperature, humidity, airflow, etc., it is easy to catch a cold. At the same time, the enclosed space reduces the exchange of indoor and outdoor air, and the indoor air is dry, which reduces the body's ability to resist infection. The dirty air makes the disease easy to spread. .

　　Indoor air "sub-health" treatment is urgent! Experts pointed out that the purification of indoor air is mainly divided into three aspects: filtering dust particles, eliminating harmful gases, and killing pathogenic bacteria. The air purifier can eliminate these three hazards at the same time, and it is currently a comprehensive and effective product.

　　At present, the domestic air purifier market is mainly divided into three categories. The first category is foreign brands. These companies have strong scale, technology, research and development and brand advantages; the second category is domestic air purifiers with strong scale and strength. Brand, the performance of some of the air purifier products of this type of company has reached the international advanced level; the third type is a large number of smaller air purifier companies, these companies mainly produce low-end products, and the quality is uneven. Qi, mainly relying on low prices to obtain market share, and its competitiveness is relatively weak.

　　As the main representative of international high-end air purifiers, the purification effect of its products has always been in the leading position in the industry. Air purifier technicians said that the air purifier can solve the main indoor pollutants that are currently harmful to the human body. The air purifier adopts a five-stage filtration system:

　　1. Preliminary filter: It captures large particles such as hair and dust, and is easy to disassemble and clean.

　　2. Antibacterial filter: Extend the service life of the charcoal filter and absorb viruses, germs and other microorganisms in the air.

　　3. Anti-virus filter tank: Filters harmful chemical gases and peculiar smells. The mixed carbon filter with more than 40 formulas can filter hundreds of different toxic chemical gases. Activated carbon is the only safe, cost-effective way to filter harmful gases and odors. Tens of thousands of tiny pores appear after carbon atoms are exposed to oxygen. It is unbelievable that a pound of activated carbon has a surface area of 24-60 hectares. The US Army uses activated carbon to prevent toxic gases to keep the troops safe. The working principle of the anti-virus canister is like a sponge, it absorbs all the harmful chemical gases, and needs to be replaced when it is saturated. The anti-virus filter contains 3~46 kg of activated carbon, which can be used for more than 3 years. The specific replacement time depends on the concentration of dust, particles and smoke in the environment. Most air purifiers only contain tens to hundreds of grams of charcoal, which cannot be effective for a long time. The activated carbon of the air purifier is not only sufficient, but also added with a special catalyst, so the purification effect is good.
