Oxygen tanks are unnecessary, costly over time and even dangerous if you're not careful with them.

Home Concentrator Glossary


LPM: Is Liters Per Minute, which is how the flow of oxygen is delivered from oxygen therapy machines.

Continuous Flow – Oxygen is being emitted at a constant rate. All home oxygen concentrators feature continuous flow settings.

Energy Usage – Measured usually in watts. Many higher capacity home concentrators can over 500 watts at their high settings. Newer, lower capacity models will average around 300 watts or less at their highest settings.

Filters – Oxygen concentrators use a filter to keep airborne debris that might be in the ambient air from entering the machine.

Humidifiers – A detachable reservoir is filled with water and installed on the concentrator, which will help moisten the oxygen before you breathe it in. Humidifiers help prevent the discomfort of dry throats and nasal passages.
