Amazingly big and effective

It is hardly believable that I continue to receive great service from my 22 year old Remstar Choice CPAP machine and am ever so pleased that these gigantic (compared to all other machines) filters are still available. With this micro-filter and the foam filter it rests upon capturing so must dust and other stuff, I am totally uncertain how you users of other systems are surviving the pollution that comes through your CPAP machine. I even use an additional in-line bacterial filter because of allergies and it turns ugly shades of gray just like the Remstar Choice filter. I am convinced that my health is better off because of this great filter.

The filter fits well.
