How to choose an air purifier when you need it.mini fan heater

　　1. The location of the air purifier is improperly placed, and the purification efficiency is greatly reduced. For the air purifier we repurchase, the amount of clean air, that is, how much air can be processed in a standard unit time (ie CADR value), that is, the size of the airflow, the general unit is m3/h. The CADR value usually matches the area of our room. Therefore, the air purifier can only purify the entire corner of the room to achieve the highest purification efficiency. The indoor air can be completely purified, otherwise the purification effect will be greatly reduced.

　　2. If the air purifier filter is not cleaned for a long time, the machine is invalid. At present, many filter air purifiers become dark and dirty after being used for a period of time. If the user does not replace the filter and does not clean the filter, the filter will be covered with dust, which will prevent the purifier from adsorbing the new filter. The effects of pollutants, dust and bacteria attached to the machine will cause secondary pollution to the indoor air.

　　3. If the sink of the humidifying air purifier is not clean, the machine will have an unpleasant smell. More air purifiers are used in northern China, and local air is drier. Many people prefer to buy humidified air purifier products, but if the sink of the machine is not cleaned in time, it will cause the filter to be molded, and the result will be in the air purifier. There will be an unpleasant smell.

　　4. The setting method of the negative ion air purifier is to charge the particles in the air and coalesce to form larger particles for precipitation, but the particles are not actually removed, but attached to the nearby surface, which is very likely Caused dust. High-pressure ion technology will produce by-products such as ozone during operation. Therefore, when using a negative i air purifier, always use the mop to drag the house many times, otherwise it will easily cause dust again.

　　The above four points are the shortcomings of using air purifiers, and these shortcomings must be avoided when using them. Otherwise, the effect of the air purifier is not great.

　　In fact, the main disadvantage of air purifiers is secondary pollution. For example, some air purifiers have a carcinogenic risk because they generate ozone during work, and people work and live in an environment with high ozone content for a long time. As we all know, all air purifiers that use negative ions and electrostatic dust removal will definitely produce ozone. It is like the protein in eggs and the water in milk. This is an objective law. Some also produce ozone. At present, the Stig purifier adopts pure physical filtration technology, which will not produce secondary pollution such as ozone. For example, Stig uses pure physical filtration technology, a five-stage filtration system, and it is impossible to produce ozone. In addition, the Stig machine does not contain any chemical harmful substances, such as its hepa filter, which is covered with an aluminum alloy cover and a lower silicone packaging. Unlike some purifiers, they are packaged in paper or plastic. When the new machine is turned on, some purifiers will have a sour smell, that is, the machine itself contains chemical harmful substances, such as formaldehyde. All Stig machines will not produce dioxide pollution, such as ozone, which is very safe, reliable and harmless.
