Boost Oxygen Portable Oxygen Cylinder with 95% Oxygen - 36L, 4x9L Oxygen Canister with Oxygen Mask for More Than 600 Inhalations - Portable Oxygen Can, Oxygen for Home use (Pink Grapefruit Flavour)

Tried different brand, so far this is the most reliable one I am using

Good product

Find the Boost Oxygen very helpful when feeling exhausted. Wouldn't like to be without it.

This item didn’t work, it’s actually the worst one I’ve ever tried. It was filthy and covered in dust when I opened the packaging so they’ve been sitting around in the warehouse for some years myself and my boyfriend who open the Clear film around the mouthpiece we both got our hands filthy. Will be sending this item back.

Great for hayfever mornings if you've got asmtha and wake up not being able to breathe

👍

I'm not convinced this works. Plus the mouth piece is too small.

Waste of money, does absolutely nothing.
