Which one removes dust better, HEPA filters or electrostatic dust collection?

HEPA filterCompared to electrostatic dust collection, is that type of dust removal more effective?

HEPA filter is currently more commonly used for air pollution of high-efficiency filter materials, made of special fiber laminated, according to the different layers, generally on the diameter of 0.3 micron particles up to 97%-99% above the filtration efficiency of bacteria particle size is generally in the range of 0.5 ~ 5μm, but the size of the pores of the HEPA filter, it is bound to be in the purification of a greater resistance, the equipment needs to be configured with a higher power motor to overcome the resistance. The device needs to be configured with a higher power motor to overcome the resistance, so that the purifier device volume may be a little larger, the difficulty of silent control will also be greater.

Another is, HEPA filter it is through the adsorption of particles to realize the purification, so after a period of time, when the dust capacity saturated, it will need to be replaced, such as the replacement is not timely, easy to cause the secondary pollution of the indoor environment, which needs to attract our attention, while the replacement of the filter will also increase the cost of use. General filter should be replaced in about 6 months, the cost is about 200-500 yuan.

Advantages of electrostatic dust collection relative to HEPA, lower resistance of the equipment, no consumables, longer service life, but because it is through high-voltage power generation, so that the dust is electrified, the process is difficult to avoid the risk of generating ozone, it is understood that the ozone in fact can be controlled, in response to this problem Haoting new air system of electrostatic dust collector optimize the spacing of the dust collection plate, expand the ionization field, rapid capture of airborne particles, the unique double Voltage technology, together with the aluminum honeycomb ozone decomposition network, can control the ozone at a near-zero level.

Another, need to add is that the air quality is good or bad, relying solely on conventional purifiers can not get a fundamental solution, the amount, fresh, clean oxygen content is more important, in the air is relatively clean place, itself can greatly reduce the breeding of various types of bacteria, mold, so we recommend that you, conditions allow, you can consider installing a new wind system with purification function, is the best solution to solve the problem of air quality! It is the best solution to solve the air quality problem!

Benefits of HEPA filter rating, technology, and size to the consumer!

HEPA filters are becoming more and more widely used, and have become a no-brainer when it comes to filtering PM2.5, with absolutely no ozone production, making them a safe technology for filtering PM2.5. Let's find out what the HEPA rating, technology and area are worth to the consumer.

First, the HEPA rating.

E10/E11/E12 are sometimes referred to as H10/H11/H12 in China.

Different levels of HEPA purification efficiency is not the same. Let's take an example to illustrate: for example, H13 has a purification efficiency of 99.95%, assuming 10,000 PM2.5 particles, then 9,995 are intercepted by the H13, and 5 PM2.5 are missed. If it's H12, then the intercepts are 9950 and the misses are 50. Both seem to intercept about the same number. But the difference in PM2.5 through the filter is huge: H12 [50] is ten times that of H13 [5]. If it's H11, then the PM2.5 missed or said through the filter is 500, which is 100 times more than H13.

From the above example we can see that when choosing a filter, it is recommended to choose a higher level H13 grade, why not H14 grade, which has too much wind resistance to be suitable for car air purifiers.

Currently we see high-end air purifiers like Blueair for home air purifiers and Kaif for car air purifiers using H13 HEPA filters. Sometimes, the H13 HEPA filter is also referred to as a medical grade HEPA filter because it can even filter bacteria.

Second, the technology of HEPA

Different technologies of HEPA will make the performance of HEPA behave differently. Ordinary HEPA is very effective in primary and secondary filtration, but within a few days, the filtration efficiency drops drastically. We usually recommend the use of long-lasting HEPA with electrostatic electret technology, and we have learned that the Fast Air 2.0 uses HEPA filters with this technology.

Simply put, the HEPA filter with electrostatic field, long-lasting electrostatic electret can enhance the electrostatic field, and make the electrostatic adsorption force lasting and stable. Through the electrostatic adsorption principle of the long-lasting electrostatic electret filter, it can effectively filter out PM2.5 and fine particles as small as 0.1 micron. The effective use of the filter will be longer.

Finally, the area of the HEPA.

If we all use H13 level of long-lasting electrostatic electret technology HEPA filter is not the same effect? Here is a business is not happy to say that the problem: that is the area, the higher the HEPA grade, the higher the cost, plus long-lasting electrostatic electret technology, there is a plus cost, if the area is increased, then the cost is also increased. Of course, for consumers, the larger the area the greater the value.

The Fastwind 2.0 Smart Car Air Purifier uses a 0.5 square meter HEPA filter with long-lasting electrostatic electret technology of H13 grade. Typical car air purifiers use a 0.17 square meter filter. Let's assume all other conditions are the same and look at the effect of filter size on lifespan.

0.5 square meters of filter is 0.17 square meters of 3 times, assuming that 0.17 service life of 3 months, then 0.5 service life is 9 months. Considering the wind resistance factor, the wind resistance of 0.17 is 3 times that of 0.5, and the larger the wind resistance, the effective filtering capacity of the filter drops to 33.%. Both of them are integrated, the service life of 0.5 is 9 times that of 0.17, which can be up to 27 months. Considering the actual situation in China, the haze is serious, PM2.5 is often more than 60, more than 100 or even up to two or three hundred, the actual service life of the ordinary car filter in China is about 1.5 months. This calculation under the actual use of 0.5 in about 13.5 months. In order to better filtering effect, the fast wind 2.0 gives the recommendation is 12 months a replacement.

When you go with a regular car air purifier if you replace the filters it takes about 8 a year. At 238 each, the price is also $1,900, or $5.20 per day.

So when choosing a HEPA mesh, it is recommended to choose a H13 grade long-lasting electrostatic electret technology with a larger area.
