Powered air-purifying respirator, abbreviated as PAPR, is a type of filtered respiratory protection equipment that relies on electric fans to overcome the resistance of respirator components. Because PAPR can effectively improve the comfort of users, enhance the reliability of protection, and improve work efficiency, this type of product is widely used in many industrial production, public safety and other fields, the global demand for various types of PAPR products is expanding, and related companies also report great enthusiasm for the development of PAPR products.

3. Key technical indicators of Powered air-purifying respirator
3.1 Air delivery volume
The protection ability of PAPR products is closely related to whether the air environment of the user's mouth and nose is "positive pressure" or not, and the positive pressure is directly related to the actual breathing volume of the user, i.e. labor intensity.
3.2 Protection time
Protection time refers to the time under the specified test conditions, from the beginning of the test medium into the filter element, to the test medium through the concentration of a limited value. Compared with the self-priming filter respirator, Powered air-purifying respirator product design airflow requirements lead to changes in filter element protection time test conditions, which indicates that the protection performance of any supporting filter element used for PAPR should be re-evaluated according to the effective airflow or initial actual airflow of PAPR.
The design characteristics of PAPR products are mainly to improve the comfort of the wearer and increase the efficiency of work while ensuring a certain level of protection. Therefore, the protection time of the filter elements used in these products is generally shorter than that of ordinary air filtration products under the same conditions. In addition, the protection time requirement specified in the standard is only the protection capacity of the filter element obtained under the laboratory test conditions, and does not represent the actual protection time obtained under the actual conditions of use. With the actual use conditions of the filter element, the protection time may be different from the protection time under the test conditions determined by this standard, which may be longer or shorter.
