Which FF mask after dreamwear?

[PaytonA]

The whistling problem is a common F&P problem. I had the same problem with F&P Zest nasal mask when I was trying to use that. One of the members back then cut some of the vent holes open and found a lot of irregularities of the diameter. Apparently these irregularities can trap some condensation which causes the whistling. I do not remember if I ever found a solution to that other than hoping that the next replacement did not have the problem. The Simplus that I have does not do the whistling thing. May be a defect that occurs when the tooling gets older (I have had my Simplus for quite a while).

One thing that you might try when washing your mask is to use a small interdental brush in addition to soapy water to clean out the vent holes. Interdental brushes are those small, round brushes used for cleaning between teeth or under dental bridges and can be purchased at drug stores.
