Do you have to use a filter bag?

Whether filter bags must be used depends on the specific application scenarios and needs. In some cases, the use of filter bags is necessary, such as in the fields of air purification, flue gas purification, dust collection, etc., where filter bags can effectively filter out impurities in the air or liquid to protect the health of the environment and the human body. However, in other occasions, such as disposable filter tea bags in home cooking, although they provide convenience, they are not necessary.

In the fields of industry and environmental protection, the application of filter bags is indispensable. For example, in air purifiers, factory ventilation systems, and automobile emission systems, filter bags effectively improve indoor air quality and protect human health by filtering particulate matter, dust, bacteria, etc. in the air. In terms of flue gas purification, filter bags are used for flue gas purification in industrial fields such as power plants and steel mills to capture harmful substances such as particulate matter and smoke in the flue gas and reduce pollution to the environment. In addition, filter bags are also used to capture dust generated in places such as factories and mines to reduce the harm of dust to the environment and the human body.

In daily life, the use of filter bags is more for convenience and hygiene. For example, disposable filter tea bags make brewing tea simple and elegant, and do not need to be cleaned. They can be discarded after use, which is convenient and hygienic. Filter bags used in washing machines can capture 95% of debris, reducing the trouble during the cleaning process. Although these application scenarios are not necessary, they provide great convenience and hygiene protection.
