For normal household use, generally, 40 liter oxygen cylinders can be used for a minimum of 72 days and a maximum of about one year. Because the oxygen storage capacity of the oxygen cylinder is fixed, the oxygen flow determines the use time. If you take oxygen once a day or several days for one hour each time, you can use it for about 72 days. If it is used once for many days, it can be used for months or even a year.
