cannot afford a cpap machine

My husband has been diagnosed with sleep apnea. We have been searching for an answer to his extreme fatigue for years. However, the insurance wants us to rent a machine for three months before they will step in. Our insurance runs out in January. We cannot afford to rent or buy. I lost my job three months ago, and have yet to find another.
Is there any place we can get a cpap machine at no cost??
