Donate: Pulmonary Fibrosis Association

Who is The Pulmonary Fibrosis Association?

The Pulmonary Fibrosis Association, Inc. is a non-profit nationwide charity incorporated in Texas and supported by public donations and fundraising events. Their mission is to raise funds to provide assistance in obtaining necessary supplemental oxygen for pulmonary fibrosis patients with limited resources, educate the public about pulmonary fibrosis, and provide support groups to share information with and encourage patients and their loved ones.

How Can You Help?

If you have a portable oxygen concentrator or home oxygen concentrator that you no longer use, you can donate it to someone who is in need. Liberty Medical accepts donations of portable or home oxygen concentrators on behalf of the Pulmonary Fibrosis Association. We will send a box with packing materials and a prepaid shipping label right to your door and then ship your concentrator to the PFA free of charge, or you can drop it off at one of our two locations! If your concentrator is in need of repair, our certified technicians will repair it and send it to the PFA. The PFA accepts POC batteries, charging cables, and all other oxygen-related accessories.
