I've been a customer of Pacific Pulmonary Services for 10 +/- years. They've provided me with BiPap, Cpap and Oxygen concentration equipment, supplies and service. You could say my life depends on the equipment, supplies and services they provide me. For year they did an Okay job of providing what I needed to keep me breathing at night while I slept. They even showed up a time or two to check out the equipment,
I do not know what happened but they stopped making house call to me. A few years into working with them I had to upgrade equipment and add an Oxygen concentrator, that worked out. Then through the years they got more and more distant, everything was done over the phone and post. Several times I asked them about servicing the oxygen concentrator they told me it does not need any servicing. That concentrator died several years ago and they replaced it. The new machine stopped functioning so I went on line and found the information Pacific Pulmonary neglected to tell me; I was supposed to change a filter every 2 years (I didn't even know it had a filter.)
Replacing the filter would have most likely fixed the first one I had.
After providing me with a Bipap device years ago they've sent me the incorrect replacements parts (twice in a row) to keep it running. It seems they lost track of the equipment they sold me. If you need support with your breathing (i. E Cpap, Bipap, Concentrator, etc.) if you value your health find an alternative to Pacific Pulmonary.
Note: I was able to get a replacement filter for my Oxygen concentrator through Amazon.com. In a couple of days I received the correct one. Go figure.
