Which is safer for air purifiers with different purification modes?
In recent years, more and more people are beginning to realize the harm caused by air pollution, and gradually use air purifiers to improve air quality. However, in addition to smog, there are many sources of pollution in life. The most harmful to people is formaldehyde, and now the air purifier can not only absorb smog but also absorb formaldehyde. What technologies are used in the air purifier on the market in addition to formaldehyde? Xiaobian has made some sorting out.
The principle of the air purifier is to promote the air circulation flow through the ventilation system, and the air to be filtered flows into the filter net from the air inlet, adsorbs and decomposes the formaldehyde molecules in the air, and reduces the formaldehyde content in the air through continuous circulation. Finally, the purpose of purifying formaldehyde is achieved.
At present, there are many best and cheap air purifiers on the market, mainly through the activated carbon filter to remove formaldehyde. It only adsorbs a variety of gaseous pollutants such as formaldehyde and toluene in the air and then stores them in the filter, which cannot be decomposed. After the purifier is used for one or two years, the filter should be replaced. Otherwise, when the filter is saturated or encounters high temperature, the adsorbed formaldehyde will be released into the air to form secondary pollution.
The air purifier is better for micro electrostatic cleaning.
Every winter, PM2.5 is almost explosion in most parts of the North. On November 8, 2014, Shenyang, Liaoning Province even reached 1400 μg/m3. The government has called on the public to minimize outdoor activities. The highway was once closed due to smog. The dangers of smog can be seen.
It is in this environment that the air purification industry was detonated. Air purification products are mainly divided into two major categories: medium purification and electronic purification.
Media cleaning requires regular replacement of the filter, which is expensive to maintain at a later stage.
There are two kinds of electronic purification: electrostatic dust removal and micro static electricity. Electrostatic dust removal will produce ozone. For people who are often indoors, there will be certain harm; while micro-static will not produce ozone, and there is no need to change the filter regularly, and the maintenance cost is very low. Aiyoute is a technology-based enterprise mainly based on micro-static. The slogan of Aiyoute is “can breathe deeply”. It not only purifies the air with high efficiency, but more importantly, it does not need to replace the filter. The maintenance cost is very low, and the product installation is also low. Very convenient. Beijing Benz Center is taking advantage of these micro-static advantages and signed a supply contract with Aiyoute.
In the future, the air purification industry will focus on user use and portability. Micro-electrostatic purification technology is a qualitative improvement for the field of air purification. It will surely break the existing technological monopoly of the traditional purification industry and achieve rapid growth.
How to make air purifiers more efficient in addition to formaldehyde
The existing best air purifier for allergies and pets in the market mostly adopt a composite type, that is, a plurality of purification technologies and material media are simultaneously used. In general, the principles of air purifier purification can be divided into three categories:
One is to use a fan to pump air into the machine, filter the air through the built-in filter, and then release the clean air. This method is called passive adsorption.
Second, the machine actively releases purified purification factors (silver ions, negative ions, photocatalyst technology, etc.) into the air, and through the characteristics of air diffusion, it reaches the corners of the room to purify the air without dead angle. This is proactive.
The third is to combine passive purification and active purification technology. It has both the filter and the air to absorb harmful substances, and the active release of purification and sterilization factors called double purification. This relatively high-end air purifier is a dual purification mode.
The air purifier is small and flexible, ready to use, and it is a good blade for formaldehyde with a release period of several years. do you know? When is the best time to remove formaldehyde with the best small room air purifier for allergies?
First, outdoor conditions are not allowed, and outdoor air pollution is serious, such as wind, rain, cold, heat, smog and other conditions that cannot be ventilated.
Second, it requires more space to use air purification products, such as perfect use during rest, use in the living room during the day, flexible and energy-saving.
Third, the room has a lot of smoke, soot, and other flavors, we can also open the air purifier to disinfect, it is best to keep driving until the odor is eliminated.
Fourth, when you are staying in a new house, you should buy an air purifier and keep the air purifier open all day. Newly renovated house furniture and walls will emit excessive formaldehyde. During the day, doors and windows should be opened as much as possible. In winter, if you can’t open the window, you need to turn on the air purifier 24 hours a day.
However, the use of air purifiers also needs to pay attention to the following points in order to make the air purifier play its best role.
First, keep the air around the air purifier flowing smoothly. Try not to put it in the corner. You can place the machine in the center of the house so that the airflow is more efficient.
The second is to check the filter screen regularly. The quality of the filter screen determines the air purification effect. Therefore, you should pay attention to changing the filter element when using it, otherwise, it will not be able to purify the air. In addition, the activated carbon with formaldehyde removal is easily saturated, and it is necessary to frequently obtain the activity under sun exposure.
Third, some air purifiers have a humidifying function. Unpurified water, after ultrasonic atomization, is an excellent environment for bacterial reproduction. It is not recommended to buy this. If you feel that the air-conditioned room is dry, you can buy a professional humidifier.
