How do you know when the can is empty? The web site is contradictory about how many inhalations, the can says up to 150 but web site says only 70, In my use it is impossible to tell when empty

I'm sorry. I do not know. I haven't used mine that much. My brother, who has COPD, measures his oxygen when he uses one of the canisters. I guess if you did that and nothing changed, it's probably empty.

I think the number of inhalations depends upon how long you hold the trigger for each one. Short inhalations lend to more. I can tell mine are getting empty when the trigger puts out less and less and then eventually puts out nothing. Then it's empty and I recycle and move on to the next one. I agree it's hard since the can feels empty even when full. Hope this helps.

that number is an Average, In colloquial language, an average is the sum of a list of numbers divided by the number of numbers in the list. In mathematics and statistics, this would be called the arithmetic mean. However, the word average may also refer to the median, mode, or other central or typical value.

When it isn't releasing anymore oxygen, that is your answer, and you know it is out.

If you gently squeeze the actuation trigger and you don't hear "hiss" or anything at all...it's out. The number of actuations will vary according to the length of the actuation, in other words, how long the trigger is depressed. So I can see one only getting seventy if you take long, deep, lung-filling "hits" vs. short "nips."

1cc is 1ml. A pint is 473 ml. Since air is 20% oxygen, an empty (but sealed) pint jar will have 95 ml of oxygen in it. One packet would /just/ suffice, but every time you open it you let more oxygen in.

There really is no way to tell. I would suggest buying an extra carbonator so you always have an extra full one on hand.

Hi - We ordered that months ago, and honestly, I can't recall how many were in the pack. something tells me that it is six, but I'm not 100 % sure. The best way to figure it out is to maybe compare the price per can and then per case, see how it balances out cost-wise, if that makes sense. Wish I could be of more help.

Not exactly sure but my guess would be 4 to 6 hours. I have run it on high in a cold hunting blind with a small canister for about 2 1/2 hours before I had to change cans. Hope this helps.

Can't tell you how long a can will last, as it is how much you use it. The can's are not refillable.

I am still on my first can of Private Reserve Wine Preservation System and it is still functioning well. You can still see the pressure of the gases hitting the surface of wine with each push of the button. I assume when you no longer can see the gas pressure hitting the surface of the wine then the can is completely empty. I have purchased two more cans that are sitting unused in reserve because I like this product very much and how convenient it is to use.

I've put a cartridge in mine, fired it a couple of times, set it down for weeks, picked it back up and it is fine. No apparent loss of pressure. Michael's answer of around 70 shots is probably pretty accurate. I haven't counted but you can definitely tell when the cartridge needs changing. You can hear when the pellet doesn't have the same punch behind it and the pellets start hitting low. I think it may be more like 50 shots? I know that when I do notice the cartridge needs changing, I unscrew the cap and only get a short "phisst" and that is it. It's empty. It uses all the CO2 effectively.

It does not have an indicator window or any other way to know how much is left. I just use it until it doesn't spray well, and then fill it up.

It would help to know much volume you are trying to fill. A single can of this product, from my use, expanded about to three times, the original bead. A single can goes a long way as long as you are not trying to fill up a box.

It depends on the airflow in the room, but I have had mine in a probably slightly above average airflow room for about a month and a half and it is about 3/4 gone and I noticed it is not quite as effective so I just ordered a refill and refilled it. But up until a few days ago it has been working great. I have one in a lower airflow room and it is still about 3/4 full. I really like this product.
