It's probably not feasible or safe to try to improvise UV yourself. Spread more air cleaners around the room.

@gardengirl778@BarryHunt008@booyah2yah@apmalong@Ghughes@Eric\u Carroll@ZiadFazel@akm5376@MarvinH2\u G2@TruthAbout\u ME2@YouAreLobbyLud你很幸运你的学校甚至会让你这么做。C-R盒子是最划算的，但可能会引起（毫无根据的）担忧，因为它们看起来是即兴创作的。
这可能是不可行的或安全的尝试即兴紫外线自己。在房间周围多铺一些空气滤清器。
