If we want to remove formaldehyde, our first reaction is to open the window and ventilate, and reduce the indoor formaldehyde concentration through the exchange of indoor and outdoor air. But in the winter, when the outside temperature is low, we don't usually open doors and windows frequently; in the hot summer, Air conditioning in the room will naturally choose to close doors and windows. At this time, in addition to the use of less purified charcoal, green plants assist in the removal of aldehydes. The use of air purifiers has become a new option for people. However, the survey found that For the question of whether 'air purifiers have the effect of removing formaldehyde', many consumers are more skeptical and consider it psychological comfort.
Air purifier in addition to formaldehyde principle
The air purifier relies on the micro-fan inside the machine to stir the indoor air and promote the circulation of air. The air to be filtered will flow into the filter through the air inlet. The molecules of formaldehyde in the air will be absorbed by the filter and decomposed. This will continue to circulate in the air. The content of formaldehyde keeps decreasing and eventually achieves the goal of purifying formaldehyde.
In theory, air purifiers can really remove formaldehyde, and to put it plainly is that activated carbon filters in air purifiers are at work. Activated carbon is already a very mature industry, its strong adsorption, in clean water, clean gas Has been widely used. For now, the physical modification and chemical modification of the double modified activated carbon, its larger specific surface area, adsorption capacity is stronger, better purification effect.
Look at the formaldehyde CADR value to relieve the aldehyde performance
So, how does an average consumer determine the strength of an air purifier in addition to formaldehyde? Simply, look at its formaldehyde CADR value. The formaldehyde CADR of air purifiers on the market varies from tens to hundreds, and the numerical value increases. The larger the amount of activated carbon used by the air purifier, the better the activated carbon quality and the larger specific surface area, the stronger the ability to remove formaldehyde.
Air purifier in addition to formaldehyde detection
In general, most businesses will present the product inspection report issued by a third-party testing agency in the product introduction. Otherwise, the actual measurement process will be recorded in a graphic or video format to prove that the product is not aldehyde. However, these methods often cannot Completely eliminate consumers' misgivings, because they did not really participate in the whole process of testing, they could not intuitively feel the formaldehyde performance of air purifiers, and the credibility of test results was naturally greatly reduced. Therefore, last month On the 20th, the industry's famous brand Xinyi commissioned Chinese Academy of Sciences testing as a third-party testing agency, and conducted the industry's first air purifier detection live broadcast in conjunction with Super Live IP 'That's something for work.' In addition to the aldehyde performance, it strives to verify for the majority of consumers in the most realistic and intuitive way: Is the air purifier really effective in addition to formaldehyde?
The test results show that under the highest grade, Xinyi Xiaobai PRO has a formaldehyde CADR of up to 548.8m3/h. This figure is very good in the air-cleaning industry. What's more worth mentioning is that in the sleep mode with minimum wind speed This air purifier also has a formaldehyde CADR of up to 212.8m3/h, which is even comparable to the maximum formaldehyde CADR of an ordinary air purifier! It is important to know that the purifier is usually used in stalls with the lowest wind speed to control noise. The CADR value is generally low, and the purification efficiency is low. The new 颐 Xiaobai PRO still has 200+ formaldehyde CADR under the sleeping file. It really can be effectively cleaned at night and it can be effectively clarified. It is not a 'performance monster'!
In general, whether or not the air purifier has the capacity of removing formaldehyde mainly depends on the activated carbon content and quality in the filter. The higher the amount of carbon used and the better the quality of the carbon, represents the large dust holding capacity of the purifier. Longer life; and a simpler way of judging is to look at the formaldehyde CADR values of the air purifier's stalls. The higher the value, the better the purifying effect!
