Don't fall for it.

I am so dissapointed in MYSELF for actually falling for this.

Its a large metal can (probably 1.5L size) lighter than a cup of water. There is no liquid in the can.

No sense of 'energy' or boost, or anything else. I thought maybe placebo, but no.

Can someone explain why the can is labeled as 15L when there is nothing in the can?

These are 1L cans filled with 15L of pure oxygen gas compressed into the canister. There is no liquid in the can of course because this is pure oxygen gas. The gas itself only weighs approximately 15g as detailed on the product itself.

This is not a stimulant drug it is just pure oxygen so you should not expect a big rush of energy on initial use.

It should be treated more like a mineral or vitamin supplement where regular use brings long term benefits.

I've been using this company for oxygen for a few years now. Others may say what they like on this site. However try living with COPD and emphysema. The oxygen they supply for me works. Obviously not as good as medical grade NHS oxygen. But for what I need it for ie... mornings when waking and at top of stairs, it works a treat. The MD of the company is really helpful too. Thank you to all that work there!

AVOID THIS CREW LIKE THE PLAQUE

AVOID THIS CREW LIKE THE PLAQUE.

Basically, you will receive a tin which will empty in 3 seconds, yes, one 3-second blast of oxygen.

TOTAL RIP OFF.

This sounds like a damaged or faulty can.

We have asked for your contact details, but you failed to reply.

We have nobody with your name ordering from us in 3 years so we are unable to resolve or follow up.

Please contact us so we can replace.

This individual claimed they didn't receive the item and we had to show proof of delivery.

Clearly they did receive it if they have managed to use it.

Didn't contact us to resolve this supposed quality issue even though we would have replaced free of charge.

All our cans are independently tested to strict British standards of oxygen purity so claims these are just "normal air" are unsubstantiated.

If you are healthy it's basically a scam

1) A healthy person's oxygen level is around 97% and so even high oxygen environment won't change the amount of oxygen in the blood much at all.
2) the amount of air oxygen you actually get from a 1 second puff is miniscule relative to your lung size so you mix something like 1 part 100% oxygen with 50 parts regular air at 20% which is still basically 20% oxygen

1. The mechanism of driving more oxygen into your system is not solely through the red blood cells. Even if you have a blood saturation of 99% you can drive more oxygen into your system through the higher partial pressure of oxygen. This results in diffusion in dissolution to the blood plasma and delivers oxygen through the plasma itself.

2. Studies with a University Hospital in London showed that 400ms of oxygen flow at the beginning of a breath is sufficient to give a significant effect on oxygen saturation. The subsequent air intake drives the oxygen into the alveoli according to the research.

There are multiple studies on our website showing the benefits of supplementing with oxygen even for healthy individuals. Please review the literature.

Sorry to hear the product didn't meet your expectations on this occasion.

Some customers do seem to have very high expectations of an immediate effect. Whilst most people get an immediate effect some do not feel anything at all initially and it's only after consistent use over time that the benefits of supplemental oxygen are evident.

This has been shown in a large number of scientific studies some of which we have put links to on our website.

Sorry to hear you were disappointed with your purchase. It sounds like you have ordered our smallest 10L can. These are specifically made in lightweight aluminium and are meant to be extremely lightweight for portability.

From the description including size it is quite clear this is not a 10L canister, but 10L of normabaric oxygen compressed into a small canister. It does also state the number of breaths expected in the description and on the packaging.

We do canisters up to 240L so if you are looking for value for money the larger cans are better suited to regular use. The 10L cans are just meant for short term use on the move.

Ordinary air is ONLY 21% whereas these are minimum 99.5% pure allowing partial pressure to drive more oxygen into your system than breathing air alone. This is why hospitals treat people with pure oxygen and don't just tell people to breathe more air.

couldn't feel anythingI through the mask, I then started to try inhaling the oxygen direct through it's nozzle. I thought at least I could aerosole some air that way.

Sorry to hear you had a poor experience with our product. Please reach out to our customer services team for a free replacement. We also have an inhaler cap version if you prefer the feel of the oxygen on your skin rather than it coming through a tube and mask.

I have bought one of their items as recently i am dealing and hopefully dealt with very unusual and annoying probelm,some sticky saliva that sticks for back of troat, give you constant feeling to spit and sometimes half-blocking your breathing canals up to feel to open the window in room and stick my head out of it for more air!!
So first time i used their product(can+mask) i used it without having breathing issue that time,did not feel a thing,am i breathing something or not,but 2nd time i had problem andnwas getting bad so i took 4-5 breaths and literually fixed on the moment my breathing,evan made normal my saliva(not sticky) and i felt fresher for a while!!!
Ps. I drink plenty of spring,mineral water

Great product, Caring Company

Great product, from a company that DOES seem to care. Ive been using Clear O2 for a while now and it has improved my well being, I use it when i get up from bed. I take 10 or 12 deep breaths using the push button on the cylinder and the breathing mask, and i feel enlivened and ready for the day.
