Filter adapter for CPAP mask

thingiverse

Turn your CPAP face mask into a particulate-filtering mask by modifying it yourself. I need an expert to tell me which type of filter material is most suitable. I'm currently using standard CPAP machine filters and MERV-13 A/C filters in my home air conditioning system. The CPAP filters I use can be found on Amazon at the following link: https://smile.amazon.com/gp/product/B07FBWJZR5 My MERV-13 A/C filter is available on Amazon as well, and its product code is B01CR9JNGS. Update: I've added a photo of my full-face CPAP mask with black tape covering the existing vents. As you know, standard CPAP masks are not sealed units. To achieve the best results, I found that using PETG and a resolution of 0.1 mm yields optimal layer compression and leak prevention.
