I have been using cpap for over 30 years and this is by far the most comfortable and best fitting mask I have ever used.

Just got this mask from Jeremy. Best company in Canada to deal with. I have been using CPAP equipment since 2014 and have been a repeat customer to Jeremy many times in the past. Always treats me with respect and the service is great. My pressure is at 14, and with this mask I haven’t had any issues with keeping the seal, and if you can maintain a good seal, you will reduce your number of events, and that is the most important thing to do.

I have been a CPAP user for over 25 years and have used many different masks and suppliers over that time. The technology has improved so much over the years and the F20 is the mask that ticks all the right boxes for me. It is comfortable to wear, easy to clean and maintain and easily meets the higher pressures of my prescription. On that same note, the service I get from Jeremy at CPAPSupply has been nothing short of stellar! There always seems to be a personal touch when placing an order. Well done Jeremy.

This F20 mask has been my go to since I started also breathing through my mouth. It has been just what I needed. As always when I placed the order Jeremy was sure to get it shipped quickly with the correct product. Nothing better than getting a product that was ordered correctly and as quick as possible

Thanks Jeremy
