In addition to formaldehyde, the air purifier is full of flicker!

Yesterday (26th), the results of the first performance evaluation of the first air purifier organized by the National Indoor Interior-Environment and Environmental Product Quality Supervision and Inspection Center were released. The results showed that the function of “removing formaldehyde” of all air purifiers inspected was basically invalid.

In order to make the evaluation results universal, the staff purchased 10 best-selling brand purifiers according to the sales ranking of e-commerce self-operated products. After a month of various tests, the staff found that the air purifier can effectively purify the particulate matter in the indoor air, but it is basically ineffective for purifying the harmful chemical gases in the air.

Not the higher the amount of clean air, the better

△ Purify PM2.5 and formaldehyde gas results

The amount of clean air should be selected according to the size of the room and the cost performance. The clean air volume is more than 100 cubic meters per hour. It is suitable for rooms of 15-20 square meters. It can reduce the PM2.5 in indoor air by 90 hours after starting up. %the above. Therefore, the blind pursuit of clean air is meaningless.

Purifier PM2.5 removal rate is up to standard

From the test results, the high-efficiency filter to purify PM2.5 technology in indoor air is very mature. From the purification technology of the ten air purifiers involved in the test, it is basically high-efficiency filtration technology and the clean air volume of nine sets. Both are above 100 cubic meters per hour, indicating that the air purifier is effective in purifying particulate matter in the indoor air.

The function of removing formaldehyde is basically invalid

Seven of the ten purifiers evaluated this time have the function of purifying formaldehyde. According to the results of the clean air removal of formaldehyde, the seven purifiers have basically no significant effect in removing formaldehyde.

What is the purification performance?
The purifying performance of an air purifier refers to the ability of an air purifier to remove a certain pollutant in indoor air. Specifically, it refers to the amount of clean air of the pollutants that can be removed by the air purifier, that is, the magnitude of the CADR value.

The best effect of a purifier, CADR value of 29m3 / h, according to this data, in a 15 square meter room, boot for 1 hour, in theory, the formaldehyde in the air is also reduced by less than 50%, formaldehyde release indoors In the case of the actual use will be even worse, most of the air purifiers on the market claim that the effect of removing formaldehyde is only a selling point.
In addition, the assessment also found that the purification capacity of the best air purifier is not directly proportional to its price, and the purifier below 1,000 yuan is more cost-effective.

Purifier life is still under test

The purifying life of the air purifier determines the use effect of the purifier and the cost of the consumer, but since the purifying life test is a relatively complicated process, the relevant tests of the National Central Laboratory are still in progress, and the results will be released in time.

Air Purifier Selection Guide that Everyone Should Know

A hotel is a place with a large flow of people, and the air environment of the hotel rooms is complicated. With the improvement of the hotel accommodation environment, whether the hotel room air environment is fresh and healthy has become an important factor affecting the hotel guest experience.
More and more hotels are beginning to deploy air purifiers in their rooms, but the quality and purification effects of air purifiers on the market are mixed. Conventional home air purifiers often cannot meet the complex air purification requirements of hotel rooms.
So, how do you choose an air purifier that can be highly purified? Before buying a suitable air purifier, first, understand what is the knowledge of the air purifier?
The working principle of most air purifiers is to use the fan to extract air, obtain a certain wind pressure through the fan, and then pass through the heavy filter to remove the particulate matter, harmful gases and bacteria in the air, and finally get clean air;
The air purifier can be selected to select the most suitable air purifier with the CADR and CMM values ​​of the air purifier as a reference. The CADR value, the Chinese name is the clean air output ratio, and the national standard unit is m3/h. From a literal point of view, the higher the CADR value, the better the purification effect. The approximate applicable area of ​​the purifier can be measured by the CADR value.
The CADR value of the inspection by the authority is more valuable.
The air purifier market has been very confusing for a long time because there is no clear standard. The new national standard clearly stipulates the key parameters of the air purifier (the most important one is CADR). After the official implementation, most manufacturers will issue test reports according to the new national standard, but they are not enforced, and there is no designated detection mechanism for the purifier. Therefore, a more authoritative third-party testing agency is required to give a credible test report.
The CADR was developed by AHAM (American Association of Home Appliance Manufacturers), so the value of the AHAM-certified CADR value is the most reliable. However, domestic air purifiers are too troublesome to detect in the United States, so the current domestic industry is more authoritative testing institutions such as China Household Appliances Testing Institute, Shanghai Environmental Protection Product Quality Supervision and Inspection Station, and Guangzhou Industrial Microbiology Testing Center.

The higher the CADR value is, the better the performance is.
The CADR value is affected by two factors, one is the primary purification rate and the other is the air volume.

The former represents how clean the air can be filtered inside the purifier, while the latter means that a fixed volume of air can be filtered several times in a certain period of time.
The ideal state is to filter the air almost every time and then filter it many times in a short period of time. But this is actually a contradiction: the higher the purification rate, the higher the filter grade of the purifier, the denser the filter is placed, and the thicker the filter, which makes the resistance of the air through the filter much larger. , resulting in a significant drop in air volume.
Therefore, the middle and low-end purifiers generally “quantify”, that is, use high air volume and more cycles to compensate for the lack of single purification efficiency. The side effect is that the filter life is very low, usually 3-6 months. replace.
The high-end purifier is “stable”, with a focus on the pursuit of ultra-high purification rate and longer filter life.

The CADR values ​​of PM2.5 and formaldehyde are separate
The CADR value is how many cubic meters of clean air can be output per hour. It should be noted that the clean air here refers to the air that does not contain certain harmful substances. For example, clean air without formaldehyde can be expressed by [CADR formaldehyde]. As for PM2.5, it does not matter. Similarly, clean air without particles is represented by [CADR particles], as for whether there is formaldehyde in it. It doesn’t matter. Therefore, there are two types of CADR specified in the new national standard for air purifiers: CADR (PM2.5, dust, etc.) and formaldehyde CADR. The two parameters represent two aspects, which are also presented separately in the test report.

What are the standards for an excellent air purifier?
For the air purifier, although the CADR value can directly reflect the purifying effect of the purifier, which machine filter can be used for a longer time, the working noise is loud, and what kind of working principle is used is also a good purifier. It should be noted at the time.

1 long-term effective
CCM (cumulative purification, in mg) is another important parameter in the new national standard for air purifiers, which specifies the amount of particulate matter or formaldehyde that can be eliminated before the filter is “discarded”. Like CADR values, CCM is also divided into particulate CCM and formaldehyde CCM, and each CCM is divided into 4 grades. The larger the CCM value, the better, indicating the longer the filter life.

2 have a clear authority inspection report

This is the strongest evidence to prove that a purifier is excellent. The published report must show the CADR and CCM test data for particulate matter and formaldehyde, respectively. The key information that should be included in the report meeting the new national standard is particulate CADR value, formaldehyde CADR value, and particulate matter CCM grade.

3 running noise is small
A good purifier with a minimum working noise of 25-35db (and the higher the CADR of the minimum file is better), the maximum working noise cannot exceed 70db. High CADR values ​​are inseparable from high air volumes, but the greater the air volume, the greater the noise. A good purifier can reduce noise by using a better fan and a more reasonable internal air duct, which makes us more comfortable.
The minimum gear of the purifier is usually used when we are resting. At this time, the purifier needs to be quiet. 25-35db is the equivalent of the sound we hear when we are quiet at night, and it hardly affects our rest. The highest 70db is the national new national standard. Any qualified household air purifier, no matter how high the CADR value, should not exceed it.

4PM2.5 numerical real-time display
Many air purifiers cannot display specific values, only roughly use different colors or use “excellent, good, medium, and poor” to display, and look ambiguous. An excellent purifier can display the value of PM2.5 in the air in real-time so that we can see the changes in indoor air quality very intuitively.

The purifier with remote control allows us to master the room air quality in real-time. When the air quality is not good, it can be driven to the maximum position before returning to the room. When you return to the room, the air quality has become better, you can adjust to the gear with less air volume, and the working noise is smaller.

The biggest source of pollution in your home may be an air purifier!

Central heating in the north began in succession, and major cities ushered in a new round of smog. “Going out to wear a mask to filter, to open the machine to clean up” has become the standard of urban life.

But the market is full of purification equipment, the effect is as good as it is?

“Big card” is not reliable

In 2016, the Beijing Consumers Association conducted a sample survey of online shopping air purifiers. Among the 50 brands, 11 brands had safety hazards during use, and the performance of 15 brand products did not meet the requirements of the new national standard. The brand accounts for more than half of the total sample.

According to the survey, the more popular brands that the public is more inclined to trust, the greater the problems such as Philips, Brutal, and Sharp, such as virtual standard performance and data fraud.

“protective umbrella” turned into a source of pollution

Blindly relying on big names is a big misunderstanding of consumers. Another misunderstanding is that air purifiers are a once-and-for-all thing.

Many brands in the market are claiming that their products have a larger CADR value (air circulation capacity). In fact, when testing CADR values, long-term effectiveness is not considered. Most purifiers use the activated carbon filter to absorb the pollutants such as pm2.5 and formaldehyde. The non-selective, water vapor, perfume, and other substances are also adsorbed. The filter is easily saturated and the service life is 1 week~ 3 months’ time.

The saturated filter has a formaldehyde removal capacity of 0. As the air flows, the formaldehyde is easily desorbed, forming a new source of pollution. Therefore, most products on the market are not effective enough to deal with formaldehyde for a long time, which is why few manufacturers dare to install formaldehyde monitoring digital display.

How to buy a reliable air purifier?

Consider the following 5 points
1. Filter purification capacity:
General purifiers have multi-layer filters for filtering different contaminants. Try to choose a purifier with a large amount of filter material. Under the conditions, understand whether the raw material quality and production process of each layer of the filter is advanced, and ensure the purification rate is above 98%.

2. Filter life:
As the use time increases, the purification capacity of the filter will decrease with the increase of deposits, and if it is not replaced in time, it will become the largest pollution source in the room. The filter and the complicated replacement process of hundreds of yuan have caused consumers to commit “delayed disease” again and again. In order not to worry about yourself, choose a filter that lasts for more than one year!

3. Air circulation capacity:
That is the CADR value we mentioned earlier, of course, the higher the better. Although it can not fully represent the purification ability, it is also the embodiment of the cycle efficiency. Generally, the family chooses a CADR value of 300 or more.

4. Whether to display in real-time:
The real-time digital display makes the air quality more intuitive. Consumers can also judge whether the purifier is effective or not and whether the filter needs to be replaced.

5. Is it silent:
The purifier should complete his work silently in the corner, which is also the basic quality of white electricity.

If you are interested, the Internet is probably a search. Most of the purifiers that meet the above conditions are more than 5,000 yuan, and today I recommend this air purification artifact – Olansi air purifier, the crowdfunding price is only 1999 yuan.
Olansi Air Purifier is funded by China’s established listed company Baoan Group. Baoan Group has been committed to controlling automobile exhaust, industrial waste gas, and domestic air pollutants for many years. The products are exported to Europe, America, and the Middle East.

I didn’t understand that the company that is unique in the industrial field, why should we continue to develop life products, the product owner said:

“The Chinese people generally trust foreign brands, but their air purifiers are mainly in addition to local pollen. The ability to remove formaldehyde and pm2.5 is not strong. The products of Europeans and Americans are not changed and sold to Chinese people. It is always inappropriate.”

Can you use the most cutting-edge technology to make a purifier that truly solves the problem of indoor air in China?

Multiple composite filters filter out multiple contaminants
Purification rate up to 99.99%

Mr. O’s air purifier uses a three-stage high-precision filter. The first-effect filter is imported from Taiwan, with high-density nylon mesh material and a well-developed pore structure. It filters 5mm dust particles and hair fluffy substances in the air.

The core filter is designed with a platinum titanium catalyst filter + nano-ceramic plate. Under the action of platinum-titanium catalyst, formaldehyde is efficiently decomposed into carbon dioxide and water, and harmful substances such as benzene and nicotine are filtered out. The service life of the filter is 3 to 5 years.

At the last stage, the US imported a HEPA filter. The glue line, peak fold and folding distance on the surface of the filter are reasonable, and the adsorption area is 3 times larger than the conventional filter. More than 80 kinds of pollutants such as pm2.5, bacteria, virus, fungal spore pollen, and asbestos metamorphic products suspended in the air were filtered, and the filtration rate was 99.99%.

350 m3/h particulate matter CADR
Guarantee 5 hours of indoor air purification for 1 hour

The Olansi air purifier adopts a circular air guiding ring air inlet, a side air inlet, and a top three-dimensional circulation design, and the airflow is large. After starting up, it produces a high concentration of negative oxygen ions (about 10 million / m3), mixing clean air, and can also embrace the mountain wind at home, regulate the nerves, and eliminate fatigue.
Japan Shenrong Import Sensor
Intelligent digital display air quality is visible in real-time

The accuracy of the sensor also determines the filtering effect. Mr. O’s air purifier adopts a Japanese Shenrong imported laser sensor to detect changes in external air pollution faster and start cleaning air earlier. Although the application cost is high, the detected data is more reliable.

In terms of the display screen, the Olansi air purifier is the first to be equipped with a professional formaldehyde monitor. The PM2.5 and formaldehyde content values ​​are displayed independently, and the air quality is comprehensively evaluated, which is not possible with other purifiers.

Sleep mode noise is 28 decibels, and daily power consumption is about 1 degree.

On the core components, the Olansi air purifier adopts a DC low-resistance fan, and the circular air guide ring of the air inlet and outlet is designed to be operated with less low noise and low noise. Only clean air and subtle wind sound accompany you to sleep.
