I've had a noticeable difference in not needing to use my rescue inhaler during the day and my breathing has been normal and effortless! Love the design of the machine as well. It's also fairly lightweight to carry with the handle to move it in my bedroom at night.
Easy set up and very quiet
Recently I purchased a Sans unit which I use in my bedroom at night. I have suffered with frequent morning headaches for many years. Since using the Sans unit, there has been a significant decrease in the number of headaches and the quality of my sleep has greatly improved. The unit is extremely quiet and I don't even realize it's on.
It does a great job, and it's quiet. I'm very happy with it!
Purchase in February 2021. Works great, looks great, is easy to move to other rooms. This was purchased to eliminate virus/bacteria to cut down our chances of getting flus and viruses, dust and pollen since I have allergies. So far doing great. Company very responsive to questions and concerns.
