Air purifier buying skills?

　　In the smog-ridden winter, the use of air purifiers to purify indoor air has become a consensus. Because of this, the market share of air purifiers has soared, but there are many brands of air purifiers on the market, and the performance, appearance and price are very different, so that consumers will inevitably feel dazzled when purchasing air purifiers. In fact, buying an air purifier is far less complicated than imagined, and a routine is enough to get it done.

　　In September 2015, the national standard for "air purifiers" was officially announced, which not only regulates the air purifier market, but also gives consumers an authoritative basis when choosing. But many people don't know what the standard is, and they are not interested in reading a bunch of professional terms and parameters. Today, I will explain it to you in plain language. Mastering this routine will not only help you choose A suitable air purifier can also teach a thing or two among the friends, showing that you are knowledgeable.

　　The core of the new national standard GB/T18801 can be summarized into the four words "three highs and one low".

　　High clean air volume: The clean air volume (CADR) is an indicator of the purification effect of the purifier. The larger the CADR value, the stronger the purification ability of the purifier and the better the purification effect.

　　High cumulative purification capacity: The higher the cumulative purification capacity (CCM) value, the more pollutants are purified and the longer the filter life.

　　High Energy Efficiency Value: The higher the energy efficiency level, the more power saving.

　　Low noise: The working noise of the instrument is generally lower than 50 decibels, which is relatively quiet. You can observe the prototype for intuitive feeling when purchasing.

　　Product part configuration:

　　1. Brand pre-filter (to vacuum more/extend the life of high-efficiency filter), 2 pieces can be used in turn;

　　2. The United States 3M4inl filter HEPA (with sterilization layer) / new decoration within one year is recommended to use a two-in-one carbon quilted purification layer;

　　3. Multi-effect compound deodorization filter;

　　4. NCF-RCO formaldehyde odor removal module assembly----standard

　　5. Double negative ion generator: work in turn, the ultra-fine ion group hardly produces ozone, which is more friendly to the environment!

　　6. The length of the power cord is 2.45 meters;

　　7. Universal casters, 2 of which have brakes.

　　The ability to degrade new decoration odor and life odor exceeds 50,000 yuan of pure imported products, and can purify dozens of indoor air pollution at the same time.
