Make sure you are using a medical grade (oil and particulate free) compressor, because aerosolized machine oil and micro metals are super bad for people to breathe in.
- adammunich 7y agoThe free piston compressors don't use oil as far as I have been able to tell. I believe they are diaphragm pumps.
- mike_d 7y agoCheap compressors (even labeled oil free) will still have residue machine oil on internal surfaces from the manufacturing process. Chinese manufacturers usually surface coat metal to prevent rusting during shipping. It might not be enough to bother you or I, but if someone is respiratory compromised to the point they are on a vent, they really need medical grade oxygen.
- adammunich 7y agoOK we can recommend a filter if the compressor is of unknown quality. I have tested our design with supplemental air from a Phillips EverFlo and it still works well.
