How to lower the cost
- Ask your utility about medical baseline or life-support rate programs — many offer real discounts.
- Portable units on battery use far less power but deliver lower flow; sizing matters medically, so change nothing without your provider.
- Keep filters clean — restricted intake raises power draw and wears the compressor.
