Replace them every 12 to 18 months as a general rule to ensure your machine is producing the correct concentration of oxygen. Compatibility Designed specifically for the Inogen Rove 4 portable oxygen concentrator. Not interchangeable with the Rove 6 (which shares columns with the G5), G3, G4,
The removable sieve columns for the Inogen Rove 4 contain the sieve filters that separate inert gases from room air and concentrate it into medical-grade oxygen. Replace them every 12 to 18 months as a general rule to ensure your machine is producing the correct concentration of oxygen.
Designed specifically for the Inogen Rove 4 portable oxygen concentrator. Not interchangeable with the Rove 6 (which shares columns with the G5), G3, G4, At Home, or other Inogen models.
2 sieve columns — a complete set for replacing both at once. (Columns work in alternating cycles, so both should be replaced together to maintain proper oxygen output.)
Replace the columns every 12 to 18 months as a general rule.
Earlier replacement may be needed depending on operating conditions. Your Rove 4 will alert you with the "Replace Columns" symbol on the display when the columns need attention.
What sieve columns do
Inside an oxygen concentrator, sieve columns are filled with a molecular-sieve material (typically zeolite) that adsorbs nitrogen from compressed room air. What passes through is the concentrated oxygen your machine delivers. Over time, the sieve material loses its capacity to bind nitrogen efficiently — which is why these columns need periodic replacement to maintain the proper oxygen concentration.
Call 1-800-775-0942 with your Rove 4's error display — we'll help confirm whether columns are the right replacement part.
