Can an air purifier really remove formaldehyde?
The answer is yes, it's just a question of more and less, fast and slow, mainly depending on what equipment you are using and which machine.
Currently in the market, many sales are exaggerating facts in many areas, emphasizing the advantages and not discussing the disadvantages. The same is true in the field of air purifiers. Many promoters claim that their own brand air purifiers remove more than 99% of formaldehyde. Some even directly claim that air purifiers purify hundreds of cubic meters of formaldehyde per hour. Seriously mislead consumers. Friends who are suspicious about this, suggest that you prepare a formaldehyde meter. In a room where formaldehyde exceeds the standard, you can turn on the air purifier to remove it and test it. After running for a period of time, check the entire indoor air quality. Don't just check the air quality at the air outlet. Is it right? The test result is either that the formaldehyde concentration is almost unchanged, or the indoor formaldehyde has increased instead.
The core principle of the air purifier is internal circulation equipment, the internal use is mainly physical filtration, with activated carbon adsorption filter, and some brands also add electrostatic dust removal. From the analysis of its principle, the removal of formaldehyde is based on the adsorption of activated carbon. The adsorption capacity of activated carbon is indeed very strong. It is widely used in the removal of peculiar smell, water purification and air purification industries. Tested in laboratory utensils, the formaldehyde adsorption effect in the unit container is good. , Up to 99% of the data comes from this, but in actual applications, the adsorption capacity of the activated carbon of the air purifier filter is really limited, and the indoor volatilization of formaldehyde is constant. Therefore, it is strongly recommended not to use an air purifier among the new house users. The removal effect of formaldehyde is in vain. And when the air purifier is used, effective indoor ventilation cannot be achieved, which increases the pollution degree of indoor decoration.
So what is the real function of the air purifier? Remove or reduce indoor odors and reduce indoor PM2.5 concentration. Since 2013, we have recognized the power and hazards of smog. In many cases, PM2.5 is as high as 300 or more, which may cause asthma in some patients with respiratory diseases. Put an air in the room. The purifier can effectively reduce indoor PM2.5 concentration and reduce the impact of haze on health.
If it is only for smog, choose an air purifier, which is economical, easy to carry, easy to move, and flexible.
If it is necessary to remove formaldehyde when the formaldehyde exceeds the standard, the most effective and practical method is to use a professional super-oxygen formaldehyde purifier. It is the latest black technology on the market. It decomposes formaldehyde through super-oxygen molecules, quickly and completely removes formaldehyde, and removes energy. In addition to removing formaldehyde, it can also kill more than 99% of common germs on the market. In addition to moving into a new house or driving a new car, it can also be used to remove second-hand smoke, refrigerator preservation, and deodorization. It has no secondary pollution and no consumables. When using the super-oxygen formaldehyde purifier to remove formaldehyde, close the doors and windows, and try not to stay indoors. After removing the formaldehyde, shut down and open the windows for ventilation. The effect is very obvious.
