Lightweight and extremely easy to use. Works like magic for reals. lol
I got this for my sister, who suffers with COPD. She uses inhaler, but she always wants and needs a little extra. She often huffs and puffs after coming up her stairs, when walking up hill, etc. A little while after I bought it to her, she called me and was really happy. So, this looks like it is doing exactly what I wanted it for. Happy camper here!
Its fairly small but has high concentration. Very potent! Love it. With Covid not slowing down anytime soon this is perfect to add with my masks and sanitizers.
Wow, I've tried many different concentrators cause my daughter has some breathing problems so we need clean air and things like this to help her be more comfortable and safer, and I've got to say this actually is the best so far out of all of them. Daughter is happily playing around the house with no issues. Worth the money.
Purchased it for my old father... he loves it and said it was useful. Recommended!
I have two similar machines, this one is portable, can work on both 110v or 220v; I take it while traveling or driving, it really works...
