@FinchTH @Infoseepage @AbraarKaran It's much more than swapping a HEPA but I have found that C-R filter replacement is much faster than original build. No cutting cardboard, just pull/cut the old tape and retape w/new filters, don't need to do anything at all to shroud.
@FinchTH@Info渗流@AbraarKaran这比换一个HEPA要多得多，但我发现C-R过滤器的更换比最初的版本快得多。不用切割硬纸板，只需拉/剪旧胶带并重新贴上新的过滤器，根本不需要做任何事情。
