This filter fits the Devilbiss model numbers 5650D, 4650D, and 3650D nebulizer systems. The air filter should be replaced every 6 months or when it appears dirty. It is a white felt cylinder about 3/4" in diameter and 1" tall. Each pack comes with 5 filters.
Air Filters for DeVilbiss Pulmomate Nebulizer Compressor (5 per pack)
They fit my old but faithful nebulizer very well. Glad I found them with you.
Down to my last nebulizer filter, I ordered a 5-pack and they came in a couple of days.
Great service and great products. :)
Very good nebulizer, nice power and easy to transport.
The filter I previously had was very old and needed replacing. I ordered new filters from JustNebulizers, in preparation for the upcoming winter season. I'm glad I found these, as they are the exact replica of what I already had.
