Air Purifier Buying Tip: The HEPA filter rating is the deciding factor in how good the machine is!

Air Purifier Buying Tips:HEPA filterThe grade is the deciding factor between a good and a bad machine!

The growing popularity of air purifiers, the corresponding purchase of more people, starting appliances need to be related to the purchase of guidelines, in fact, as long as the attention of the following three points, especially the last one, can reduce the detour you take to find the right air purifier.

Air Purifier Buying Tips:

1, look at the life of the filter material, it is best to choose the purification and filtration cartridge with regeneration function to extend its life.

For example, the CCM (Cumulative Clean Mass) is the cumulative cleaning mass. The higher the value, the longer the filter life cycle and the more pollutants accumulated inside.

However, CCM has two different sets of standards for particulate matter and formaldehyde, both of which have four ratings, P1-P4 and F1-F4, with level 1 being the lowest and level 4 being the highest. In other words, P4 and F4 (12000mg and 1500mg respectively) are the highest ratings.

2, look at the purification technology, different purification technology differences will bring different use effect.

CADR represents the clean air output ratio, that is, the total amount of clean air output per unit of time after filtering through the purifier, the unit is m/h, including particulate CADR and formaldehyde CADR, which is the most important indicator for determining the strength of purification ability. Generally speaking, the larger the value, the higher the purification efficiency of the air purifier.

3, look at the filter, choose H11 grade or above HEPA filter.

The HEPA filter is the core component in an air purifier, and whether or not it uses a HEPA filter is the deciding factor in our choice of machine. If it doesn't, there is basically no need to consider it. If it does, the material and grade of the filter should also be examined. Typically, the most common in air purifiers is the H rating, where H13-rated HEPA filters can achieve a total efficiency of 99.95%, and H14 is 99.995%.

4. Minimum decibel value

The decibel value, which is also the sound the machine makes when it is running, is also critical because air purifiers often need to be activated for a long period of time to be effective, and if the sound is too noisy, it will be difficult to tolerate. Generally speaking, the decibel value of the lowest gear of the machine should not exceed 40 decibels at night when it is quiet, otherwise it will disturb people's sleep.

What filter cartridges do purifier manufacturers typically use?

At present, the domestic purifier market is more chaotic, many purifier manufacturers just a publicity purification efficiency 99.99%, and its use of the filter specifications generally take an evasive attitude, which is rarely seen online about the product filter specifications level of the reasons for the introduction. Some misguided users think that the higher the HEPA level of the cartridge, the better, the best is H12, or even H13, then we are familiar with some of the well-known brands are actually using the use of what cartridges?

The picture below shows the product brochure of Sharp, a traditional international purifier manufacturer, which has been one of the top sellers in China. The description of this product is clearly labeled "HEPA class H10".

Priced at up to 10,000 yuan more than the medical grade purifier IQ air, also used the same H11 level of filters, as shown below, its role and function of the specifications of the filter is also described in detail. IQ air of this filter element domestic price of 1,280 yuan, the price of foreign tax excluded price of 79 U.S. dollars.

In summary, HEPA filters have specifications according to the level of filtration capacity, but not the higher the filter specifications of the product purification performance is necessarily better. For the choice of HEPA filters, different manufacturers will make the best balance between the level of filters and air purification through the effectiveness of the air to choose. If you do not take into account the comprehensive design of the product, leaving aside the measured air purification performance only empty talk about the level of the filter, obviously lack of a basic understanding of the working principle of air purifiers!
