 Zhejiang five sets of the "Search" section on the air purifier air purifier interviewed Hanjing Used to be effective on the market is now so much a wide variety of air purifiers, they clean the air in the end there is no use? I put this tricky question thrown at staff Shanghai Environmental Protection Product Quality Supervision and Inspection Station of air treatment, the other gives an affirmative reply: From a technical point of view, it is useful. "But this 'useful' is conditional." The staff said, each air purifier has its use limitations, first used only within a certain area of ??space, beyond the scope of its use, then purifying function on the weak; Also under the specified conditions, such as filters should be changed regularly, clean, or used poorly can cause secondary pollution of indoor air purifier air; but also to ensure the normal use of the air inside the machine can control, such as swing put in the correct position. So, if you want to buy an air purifier, we must look at the selection of products for compliance with standards, which can absorb harmful substances, but also to look at the use of cleaner area, the purification efficiency. Do not let the cleaner "spit" hazardous substance "must remind consumers to prevent secondary pollution of air purifier in your home." Whether it is the air purifier industry or environmental product testing staff, have repeatedly reminded I must inform all this. Plough Chongqing Environmental Engineering Limited Mr. Han in the air purification industry with "spit" to describe air purifier secondary pollution. "Using a long time, air purifiers might spit out harmful substances," he said, a lot of people have a consumer misunderstanding that the air purifier is the most clean, no cleaning, some businesses deliberately not inform consumers of the fact that the filter needs to be updated lead had become a source of indoor air pollution in many home air purifier in use for some time. Air purifiers, like drinking fountains as its filter needs to be replaced regularly. Such as activated carbon, the best updated every three months. So he suggested that we'd better buy a filter that has an automatic update feature to remind air purifier. Without this feature, but also ask how long the validity related materials, updating the required filter where to buy. What the reaction of people being poisoned by formaldehyde formaldehyde at low concentrations it initially irritate the eye mucous membranes, upper respiratory tract stimulation slightly higher concentrations, causing coughing, chest tightness, and forehead feel special pressure, and mucosal ulceration, and then cause inflammation in the lungs. One of the most sensitive sense of smell and irritation, so the main hazard for the stimulating effect on the performance of the mucosa. Formaldehyde easily absorbed through the respiratory tract, nasal inhalation of formaldehyde 93% retention in the nasal tissue, there will be severe respiratory tract irritation and edema inhaled at high concentrations, increased airway resistance, decreased respiratory rate, eye irritation, headaches. According to reports, when the air formaldehyde content of 0.06 to 1.2 mg / cubic meter, you can smell the taste; 0.01 to 1.9 mg / cubic meter, eye tingling; 0.1 to 3.1 mg / cubic meter, throat excitement; reach 5.0 to 6.2 mg / cubic meter, 30 minutes exposure to which people will cry; 12 to 25 mg / cubic meter, from which one hour would strongly tears; 37 to 60 mg / cubic meter, there will be edema, inflammation, pneumonia; 60 to 125 mg / cubic meter, people will die. Human repeated inhalation of small doses of formaldehyde can trigger allergic reactions, asthma; formaldehyde direct contact with the skin can cause allergic dermatitis, pigmentation and necrosis. With a variety of mammalian cells in vitro test results of indoor air treatment, formaldehyde has proven to induce gene mutations in mammalian cells the role and effect on DNA damage. Experimental animals exposed to high concentrations of inhaled can cause nasal squamous cell carcinoma. Epidemiological survey showed that the risk of exposure to formaldehyde nose, nasopharynx, and an increased risk of oral cancer - Plough Chongqing Environmental Engineering Limited.
