Answer: air purifier is a very amazing device, it is hot in the haze rampant in the times, we are in a panic, panic to hold the air purifier home, before using it always hope that it can solve the problem, but after using it to know that it is not so much the case, today we will talk about its advantages and disadvantages, for your reference.
Before understanding its advantages and disadvantages, let's look at its structure and basic operating principle:Air purifier, the first to the floor-based, and now there are wall-mounted. Regardless of the form, its internal mainly by the filter tank, fan and power circuitry, the filter tank usually coarse filter, high-efficiency filter and activated carbon filter composition.
When the user starts the air purifier, the internal motor begins to rotate, the indoor air will be sucked into the machine, the air first through the coarse filter, will be on the hair and some of the large particles of dust to intercept; and then the air comes to the high-efficiency filter, high-efficiency filters will be intercepted pm2.5 dust, and then come to the activated charcoal filter, the filter is mainly to adsorb formaldehyde particles in the air and odor. The air is processed through them and then blown out from the air outlet.
Now some air purifiers are also set up inside the machine ozone generator, violet light sterilization, when the filter adsorption of odors after the air passes through, it will kill the bacteria in the air, the air circulates into the machine, to achieve the role of purification and sterilization.
Disadvantages:1, the noise problem. Machine in operation, mainly fan generated after the operation, the airflow from the air inlet through the filter, in the daytime is okay, if the bedroom at night, is very crash.
2, the filtration effect is less than ideal. From the front of the basic operating principle can be seen, the machine's filtration, first of all, all rely on the internal motor rotation inhalation of indoor air, the motor's power determines the amount of incoming and outgoing air volume. Then the area of the filter is limited, with the growth of time, the filtering effect will be worse and worse.
3, replace the filter more frequently. This problem is when the filter appears too much dust, it is necessary to replace, in addition to the coarse filter can be cleaned inside the purifier, the other need to be replaced; replacement time is mainly to the user's environmental cleanliness is directly related to some families are 3 months, while some families are 6-8 months to replace the filter at least a few hundred dollars, which is the reason that many people lamented the purchase of a cheap, high cost of use.
Advantages:
1. Increases the internal circulation of indoor air. When you have it, it will allow the air inside the room to circulate internally, which will make for a better air experience; just like when we use internal circulation inside a car, it won't feel particularly stuffy.
2. It moderates indoor pollution. The operation of the air purifier can only be said to alleviate the indoor air quality to a certain extent, because if you let it match the volume of the space, its noise and can not stand; so only compromise considerations, so that its filtration effect is discounted, and ultimately rendered the effect is the degree of purification is less than ideal.
3, easy to move, can be a multi-purpose. Because the air purifier is floor to ceiling, so a family can only consider one or two, especially suitable for some independent space needs air treatment of the household, such as the villa's audio-visual room, mahjong room, etc., where the need to move the effect of the real.
SummaryThe use of air purifiers can only be a large machine with a small space, and timely replacement of filters, in order to achieve a better use of the effect. Therefore, in the renovation of the house, can install a new air system to be able to design and install it well, never expect to use it later to solve the air quality problem well.
