Since the word PM2.5 into a hot spot, on the air quality awareness is greatly improved, focusing on the consumer mentality, many electronics manufacturers have reached the market a lot of air purification equipment, air conditioning also launched the formaldehyde removal function, a function of the price of natural high. While the manufacturers competing claims their product purification equipment can be effective against PM2.5, to attract buyers eye, for a time, the stores in the air purification equipment sales soared.
Recently, many manufacturers have introduced a different type of air purification equipment, ranging from a few hundred dollars to several thousand dollars. A function of air purification equipment is very eye-catching billboard 96%: "the removal of formaldehyde, benzene removal 96.5%, 99.9% removal efficiency of dust removal function, 99.9%." Store sales staff said, if the air is dry, you can choose to have a humidification function of the purification equipment, and stressed that the removal of PM2.5 is the most basic function of air purification equipment".
The sales staff at a 3000 yuan air purification equipment, the purification equipment can match medical purification effect, can filter the suspended particles with diameter less than 0.3 microns, and some even can filter 0.03 micron particles, "the PM2.5 is a piece of cake", the clearance rate can reach 99%. This salesperson told Xiao Bian, although most of the air purification equipment price is not cheap, but the price of high purification equipment sales are not worse than the low price, more than 2000 yuan of sales.
On the Internet, air purification equipment is also a hot commodity, variety and style more than the physical stores. In the online mall, some air purification equipment is the seller publicity miraculous can remove secondhand smoke, dust, pollen, droplets, and particulate matter can play dust, anti radiation, anti allergy, regulating disease, blood purification, air defense and carcinogens, improve sleep and other health effects.
Shopping malls in the air purification equipment mostly propaganda has multiple filtration system, negative ion, antibacterial layer and so on high-tech content, the impurities, particulate matter, dust removal, harmful gas, sterilization and decomposition of harmful gases in the air filter; some adds a layer of antibacterial coating, which can eliminate bacteria and fungi. Sales personnel, air purification principle has 3 kinds, namely physical and chemical type and compound type, the current market sales of air purification equipment mostly compound, which rely on physical filtration (mainly carbon composition) to remove larger dust particles in the air, and then through the chemical reaction decomposition of harmful air the formaldehyde, benzene etc..
It is understood that the principle of purification of air purification equipment is mainly two kinds, one is the high voltage electrostatic precipitation, the other is through the active carbon adsorption. But most of the air purification equipment can not completely remove formaldehyde, there are two reasons: one is the existence of formaldehyde non disposable, but slowly accumulated in the long process of decoration, formaldehyde from various vector Everfount, difficult to achieve rapid and effective removal, requires a long process of volatile. In addition, a lot of air purification equipment working principle is by physical adsorption of activated carbon, the efficiency is relatively low, basically can not achieve the purification effect of the whole room, part of the general can clean the room, the room in the infant can be considered a necessity, not other places. When the overall air environment is poor, the use of a single air purification equipment to help the human body is not.
