Exclusive explanation on how to buy energy-saving ffu air purifier.

Don't blindly pursue some brands when choosing an air purifier, it depends on what kind of technology is used, what is the working principle of the equipment and what kind of purification method is used. Choosing the right air purifier is a technical activity, which should be considered comprehensively from many aspects, the most important of which is based on the purification principle and the technology adopted.

Pay attention to a few key points when choosing, and don't put the cart before the horse and lose the watermelon. The following points should be kept in mind:

First of all, it depends on the parameter value, and it is necessary to choose three highs and one low, which is in line with the new national standard.

Secondly, considering the purification ability of the air purifier in terms of function, technology and effect, negative ion function can be selected.

Furthermore, it is necessary to comprehensively consider the power consumption, noise and price of the air purifier, and it is best to have low power consumption and no noise.

Look at the service again. Look at the attitude of customer service before buying. Do you have a guarantee or something? Ask for a guarantee.

At present, the common air purifiers on the market can be roughly divided into two categories: traditional fan filter air purifiers and active negative ion air purifiers. Different equipment, different purification principles, except PM2.5, the effect is definitely different.

The former mainly relies on the air volume of the fan for adsorption filtration when the air passes through the filter screen, which requires a lot of air volume of the fan and limits the diameter of the filter screen. For some fine particles, the effect may be different from the expected one.

The latter is mainly through the dust suppression, sterilization and coagulation and precipitation of negative ions. The smaller the particles, the more obvious the effect, and there is no need for fans and filters. Of course, not all negative ions are so significant, only ecological negative oxygen ions with small particle size, high activity and long natural migration distance are better.

At present, there are not many technologies that can artificially produce such ecological negative oxygen ions in China. The leading technologies are ecological negative ion generation chip technology, nano fullerene negative ion releaser technology, and ecological negative ion generator technology with negative ion system and pollutant collection system. When identifying equipment, you should carefully ask the technology adopted by the machine to avoid buying negative ion air purifiers with relatively general effects.
