When using an air purifier, what misunderstandings will reduce its efficiency

　　When using an air purifier, common misunderstandings will significantly reduce its purification efficiency, mainly including the following points:

　　The air purifier is placed against the wall or in the corner

　　In order to save space, many people put the air purifier close to the wall or in the corner, which will hinder the air circulation of the air inlet and outlet, resulting in a decrease in purification efficiency. In addition, dust is easily accumulated in the corner, and the purifier inhaling too many large particles of dust will also affect the effect. The correct approach is to keep the purifier at least 1 to 2 meters away from the wall and place it in a location with good air circulation and close to the activity area.

　　Place the air purifier in a well-ventilated location and use it with the window open

　　Many people mistakenly believe that placing the purifier in a well-ventilated place or using it with the window open can purify the air faster. In fact, this will cause frequent exchange of indoor and outdoor air, and the purifier will find it difficult to effectively reduce the concentration of indoor pollutants. Doors and windows should be closed so that the air purifier can work in a relatively closed environment to quickly and effectively purify the indoor air.

　　The filter is not cleaned or replaced in time

　　The HEPA filter will gradually saturate as the adsorbed particles increase, resulting in reduced purification efficiency and increased energy consumption. The particles on the filter may also become a breeding ground for bacteria and viruses. If the filter is not replaced for a long time, it will not only be ineffective, but may also cause secondary pollution. Therefore, it is necessary to clean it regularly and replace the filter in time according to the instructions.

　　Use with a humidifier

　　When the air purifier is used with an ordinary humidifier, water molecules will provide an environment for pathogens to attach and reproduce, thereby reducing the purification efficiency. Some air purifiers with humidification functions are designed to avoid this problem, but ordinary humidifiers should be used with caution when used with purifiers.

　　Improper placement height

　　The placement height of the air purifier also affects the purification effect. For example, a family with smokers should place the purifier in a higher position (such as a desktop) to better absorb smoke particles; if there are no smokers, it can be placed in a lower position (such as the ground) to filter more suspended particles.

　　Place it only in a single room such as a bedroom

　　The air purifier has a limited coverage area. If it is only placed in the bedroom, the air pollution in activity areas such as the living room and study cannot be effectively purified. Multiple purifiers should be reasonably moved or configured according to the activity areas of family members.

　　In summary, avoiding the above misunderstandings, placing the air purifier correctly, using it in a closed environment, replacing the filter regularly, properly matching the humidifier and choosing the appropriate placement height can maximize the purification efficiency of the air purifier.
