Ministry of Supply makes two masks, which both fit their proprietary filter. I only tested their Apollo mask, however. The filter is extremely high quality and tested by Nelson Labs. The Apollo mask is super soft and has a good integrated nosepiece that adjusts easily without feeling like it will break. The website says the fabric utilizes NASA-developed Phase Change Material and a moisture-wicking pique-knit to quickly dry breath-based condensation and reduce clamminess during regular use. The behind-the-ear elastic is not very adjustable and makes my ears hurt after a relatively short time. The filter is relatively easy to install, but compared to the Happy Mask or Halo Mask it is a one-time use for no more than eight hours and feels less substantive than Halo especially.
