A good air purifier can purify most of the harmful particles in the air to a certain extent, and can really achieve the effect of clean air.

However, to choose an air purifier, we must first understand the selection criteria of the air purifier. First of all, the air purifier is good or bad, mainly considering the output ratio of clean air. The larger the output rate, the better the purification effect is.

There are several hard indicators for the current air purifier measurement:

1. To ensure that the indoor air reaches a certain number of air changes, the current international standard is not less than 5 times;

2. The purification efficiency of the air purifier should be high. If there are continuous pollution sources in the room, these two indicators can keep the indoor pollutants at a relatively low level.

3. It is recommended to choose an air purifier with a larger fan volume. In particular, in the filter air purifier, there is a fan as the energy source of the air circulation system, because the air volume is large, and the filtering effect and the purifying ability are relatively large.

There are many styles of air purifiers. What should you pay attention to when selecting an air purifier?

1, performance

The emphasis on removing PM2.5 is that the CADR value is indeed high, but never mentioning formaldehyde, resulting in a super low CAD value of formaldehyde. Completely weak against common formaldehyde pollution.

2, energy efficiency

In some places, the air purifiers are normally open 24H, and a high-energy purifier is used for several tens of yuan. The low-carbon, environmentally-friendly, energy-efficient, green energy air purifier is our first choice.

3, filter

In January, a small change, a big change in March, invisible consumption can not afford, a year of filter net top an air purifier, the durability of the filter can be said to be very important.

The air purifier developed by Shangmeng Technology is co-operated by China and Canada's Shangmeng Science and Technology. It uses Shangmeng independent nanotechnology, nano-platinum decomposition of formaldehyde technology and nano-silver high-efficiency sterilization technology to efficiently remove PM2.5 and decompose harmful gases such as formaldehyde. , kill harmful bacteria, fungi, mites, and even viruses. Nano silver sterilization filter, with an average particle size of 15nm, can kill up to 650 kinds of bacteria, fungi and viruses, physical sterilization, long-lasting action, and no resistance.

The nano-silver & nano-platinum -titanium composite nano-materials are self-developed nano-materials, which have high catalytic decomposition rate, change the adsorption effect of the previous air purifier, and directly decompose harmful bacteria such as formaldehyde, benzene and TVOC; The layer has also been modified, and the composite nano-catalyst is transformed into a modified activated carbon filter which is decomposed while adsorbing, which does not cause secondary pollution, changes the durability of the filter, prolongs the service life, and greatly reduces the follow-up of the user. The cost.

Finally, the market price of air purifiers is chaotic, hundreds to tens of thousands. The safest and most effective air purifiers are physical purification types, except particulate matter and gaseous pollutants. Other humidification, aromatherapy, ultraviolet light, and static electricity are all likely to cause secondary pollution. It is recommended that users do not have to pay for these fancy features.
