All cleaning work in the 10,000-level laminar flow operating room requires wet cloth wiping during the operation of the purification system. Only in this way can the clean environment be protected as far as possible from infection! The following is a summary of the decoration of laminar flow operating room. Its specific work can be divided into the following aspects:
(1) After the operation, all kinds of dirt should be removed immediately, and classified into waterproof and pollution-proof bags, sealed, and transported from the dirt passage. Wipe all kinds of equipment and tidy up the operating room so as to avoid air pollution caused by dirt staying indoors for a long time.

(5) Sampling the air and equipment surface of 10,000-grade laminar flow operating room every month for bacterial culture; testing the number of air dust particles, noise, temperature and humidity, and registering the results for the record. The primary and intermediate filters will be replaced once every 6 months. Replacement of efficient filters every year.
(5) Clean the coarse filter, intermediate filter and return air outlet device once to ensure the dust filtering effect.
