Today, the epidemic is still fermenting. For home users, it is important to maintain ventilation indoors. This is an important part of protecting the epidemic at home. It is better to have a good air purifier at home. However, everyone also has such doubts. Is buying an air purifier at home useful for the outbreak virus?
So what does an air purifier do?
Most air purifiers extract a certain volume of polluted air through the motor in the equipment. After filtering layer by layer, they release clean air, thereby reducing indoor pollutants, improving air quality, and removing odors. If the decoration owner wants to remove formaldehyde after decoration, and the user wants to adsorb indoor haze and bacteria, they can be carried out through an air purifier. Of course, the actual process will be much more complicated than we think.
At present, there is no direct evidence to prove that domestic air purifiers can adsorb or kill viruses. However, based on the analysis of its principles, Chang expects that even ordinary air purifiers at home or in the office will have certain effects on improving indoor air quality and reducing the risk of infection. However, in the face of new coronaviruses, air purifiers cannot completely absorb and kill viruses.
The transmission of coronavirus is droplet transmission and contact transmission. Two other transmission modes: fecal-mouth transmission and aerosol transmission have yet to be confirmed. So, can air purifiers help protect against the new coronavirus epidemic? The air purifiers suck in air through a fan, purify it through a filter membrane, and then discharge it. In this process, the filter membrane absorbs suspended matter in the environment, including aerosol Etc., so theoretically it can help prevent and control viruses. "
In addition, the aerosol that has been repeatedly mentioned recently is actually an air pollutant that has been neglected by us and has a large impact on human health. What we call air pollutants are mainly divided into three categories: particulate matter, gaseous pollutants and biological pollutants. The biological pollutants are mainly transmitted in the form of biological aerosols, which include bacteria, fungi, mold spores, pollen, dander, allergens, viruses, and dust mite industry parasite eggs. Bio-aerosols generally have a particle size between 0.1 and 1 μm, which can spread quickly as people cough, sneeze, etc., causing allergies and causing respiratory diseases. Studies have shown that nearly 20% of respiratory diseases are caused by biological aerosols. Therefore, for the health of family members, especially families with elderly, children or respiratory patients should be equipped with an air purifier.
How to make the air purifier better
Some studies have suggested that harmful substances such as bacterial viruses in indoor air often cannot exist alone, and they are usually transmitted through droplets and aerosols attached to suspended particles in the air. The main function of air purifiers is to transfer these air The suspended particles in the air are effectively blocked to achieve the purpose of purifying the air. For consumers, if the home air purifier can better purify the indoor air, we recommend that you pay attention to the following three points when using it.
1. Placed correctly
The location of the purifier is somewhat particular. If conditions permit, it is best to place it in the center of the room, especially the purifier cannot be placed against the wall, which will greatly reduce the purification effect. For placement, a certain distance from the wall is required to ensure that the air flowing in and out of the machine is smooth and helps the indoor air circulation.
Do not put the air purifier with the water container or the humidifier together to prevent water vapor from entering the air purifier, causing damage to the machine or causing an electric shock.
2. Open the window timely
In fact, the air purifier should be carried out in a relatively closed space during normal work. At this time, often opening doors and windows will increase the pressure of the air purifier and reduce the purification effect. The user can open the window for ventilation when going out, or proper ventilation when the outdoor air is good.
3.Plug the power supply correctly
If we do not use the air purifier for a long time, we must unplug the power supply. When unplugging the power supply, we must hold the plug. Do not pull the power cord to pull the plug, otherwise it may easily cause power damage or electric shock.
For removing bacteria, viruses, particles, pollen and other materials, the air purifier has a good purification effect, so if you do not have economic pressure and want to improve the indoor breathing environment, it is still necessary to place an air purifier at home.
