Devilbiss Co 3655D-601 Air Inlet Filter FOR 3655D 5/Pk

Fits perfectly in my Nebulizer machine and a good value for the quantity

It is really hard to find the right filters for our Nebulizer, it’s an older model. These were a perfect fit. I love that it is conveniently shipped right to my door, I didn’t have to drive 20–30 minutes to pick it up!

fast shipping, great packaging, fits perfectly for my machine. thank you for a flawless transaction!

I use the Devilbiss Co 3655D nebulizer daily and was in need of replacement inlet filters so I purchased these. They are listed for this model but they don't quite fit. They are slightly too small in diameter and are loose fitting when in place. I can't begin to tell you how many times it's fallen out and I'm searching under the bed, dresser, night table or questioning if the cat got it and is never to be seen again. Thank goodness it's a multiple pack. If you use these, be careful of this looseness. The filter does work thus 4 stars.

Received next day just as ordered. These actually fit in and STAY IN my Devilbiss 3655D Pulmoaide Compact Nebulizer. I have one for my toddler who has asthma and the one the pharmacy gave us fell out constantly. They wouldn't replace or even sell me a new one so I found these on Amazon and they worked perfectly.

I have had my nebulizer machine for about 12 years. First time ordering replacement filters online. These fit perfectly and seem to be of the exact same quality as previous filters. Working fine. Will order again.

These are just a teeny bit shorter than the original. Don't stay secure so I put a piece of tape across the top to hold it in.

...how to rate this, because I have nothing else to compare it to, but I've used them on a nebulizer and the unit worked so I'm giving it 5 stars. They're clean, not dirty, seem new... not sure what else to say or judge them by.
