@GizmoOcean @Mw_ottawa @trendless @3M @JimRosenthal4 @CorsIAQ I don't. Only thing I know of is commercial air cleaner guide from this account. They're somewhat more expensive than building CR but many are quiet if not run at full speed.

@GizmoOcean@Mw_ottawa@trendless@3M@JimRosenthal4@CorsIAQ我不知道。我知道的唯一一件事是这个账户的商业空气滤清器指南。它们比建造CR要贵一些，但如果不是全速运行，很多都是安静的。
