A Must for CPAP Users.
I have used these filters for my wife's CPAP Machine for years as a final filter coming out of her machine, a ResMed Phillips Respironics Pro.<br /><br />It shows that despite the 2 prior filters on the machine dust and dirt does get through to the hose so I highly recommend them for anyone using a CPAP no matter the brand or type.<br /><br />I have paid more buying these filters over the years until I decided to check Amazon and found these excellently priced filters I could purchase and afford in bulk..<br /><br />YES, I'd recommend these to a friend and again ANYONE who has to breath through a CPAP nightly to prevent undesirable concentrations of debris from being pumped into your respiratory system.. Just look at your final filter after about a week or two, yes that one that you added and the manufacturer didn't even have on there in the first place and you'll see what I am talking about.
