Hong Kong people are gradually beginning to pay attention to the importance of air quality, but now in addition to the serious pollution outside the city environment, indoor space is also different levels of pollution, formaldehyde, benzene, VOC and organic compounds pose a threat to human health. To improve the situation, it is necessary to buy an air purifier for indoor environment, there are many types of products on the market, among which filters and negative ions are more commonly used. So, which one is the best air purifier to buy? Before choosing, we need to fully understand the product.
Recommended Filter Styles for Air Purifiers
The filters on the market include HEPA filter and activated carbon filter, of which HEPA filter is recommended by more experts. This kind of air purifier is recommended to buy because the material of this kind of filter is made of chemical fiber and glass fiber, which has a significant isolation effect on some bacteria and harmful microorganisms, animal hair or dander and other microparticles, but the disadvantage is that it can't filter the odor and can't be cleaned. Activated carbon filters can adsorb odors, but they do not keep out dust.
Recommended Negative Ion Models for Air Purifiers
In addition to the filter, the negative ion model is recommended for air purifiers. This product can attach a negative charge to dust and then add weight to it before it falls to the ground, which has a good effect on stopping dust and allergens. However, the range of this model is relatively narrow, and the effect is not significant enough when the home environment is large. Therefore, air purifier recommended negative ion technology with HEPA filter together, the effect will be better.
Recommended size of air purifier
The size of the living environment will have an impact on the effectiveness of the air purifier, so when purchasing, the recommended size of the air purifier has a certain significance for reference. However, the Hong Kong Consumer Council has also pointed out that even if the air purifier is suitable for larger space, the speed of removing pollutants may not be better, because the pollution level of the room can not be ignored, coupled with the fact that different brands in the calculation of the area of the slightly different, so consult a professional before purchasing.
