every restaurant will install an oil fume purifier to purify kitchen oil fume and odor. The Law on Prevention and Control of Air Pollution also stipulates that catering units must install oil fume purification facilities to strictly control oil fume emission. However, what kind of oil fume purifier to buy makes consumers puzzled. From the current oil fume purification market, you will find that the price of oil fume purifier ranges from several hundred to several thousand, and many consumers are dazzled by such uneven prices. In particular, Xiaobai, who doesn't know how to do it, can easily fall into the "trap" of a hundred-dollar fume purifier. Why can't a hundred-dollar fume purifier be bought?

From the quality analysis

Take the lampblack purifier in 211 yuan as an example: You get what you pay for, and the lampblack purifier in 211 yuan is usually high-altitude or filter-type one. In the process of use, the filter cotton in the purifier needs to be replaced frequently, and the later maintenance cost is much higher than the price of the lampblack purifier itself: it is very cheap to choose the material, and to put it bluntly, an iron box contains a very small and inferior electric field.

Analysis on the purification effect

The purification effect of the high-altitude fume purifier is generally about 51%-61% due to the limitation of its own materials, but the purification effect of the high-altitude fume purifier in 211 yuan may not even reach 21%, and the purification effect is basically absent; The comparative purification efficiency of low-altitude lampblack purifier is generally above 85%. For example, the purification effect of Weidun lampblack purifier can reach above 95%!

Analysis from the long-term operation of restaurants

According to the current domestic pollutant emission control requirements, the maximum allowable emission concentrations of non-methane total hydrocarbons (NMHC), oil fume and particulate matter emitted by catering service units are: oil fume, with the maximum allowable emission concentration of 1.1 mg/m3; Particulate matter, maximum allowable discharge concentration: 5.1 mg/m3; Non-methane total hydrocarbon, maximum allowable emission concentration: 11.1mg/m3. The lampblack purifier with 211 yuan price is far from meeting the above emission control requirements, so the restaurant may face the risk of closing down for rectification at any time! It is not conducive to the operation of catering, and the advantages and disadvantages are clear.

here xiaobian suggests to choose a low-altitude direct-discharge fume purifier at a lower cost, so as to ensure that all indicators can reach the standard, otherwise, once it is checked, it will face rectification and fines.
