@GizmoOcean @Mw_ottawa @trendless @3M @JimRosenthal4 @CorsIAQ To be clear, those AC powered fans are WAY more powerful than PC fans. I don't know how effective something built with PC fans would really be, even with better filters. Probably only useful for a very small space.
@GizmoOcean@Mw_ottawa@trendless@3M@JimRosenthal4@CorsIAQ明确地说，这些交流电源的风扇比PC风扇强大得多。我不知道用PC风扇制作的东西会有多有效，即使有更好的过滤器。可能只对非常小的空间有用。
