Maid o Mist

I just picked up a maid O Mist 5L with 5 orifices (0.04 to 0.185") to see how well this inexpensive air vent works. I don't know how it stacks up against other vents but this model is about half what a Hoffman 1a is and the fixed vents they offer can be had for half the price of the 5L if you look around.

Does anyone know of a reason not to use these?

    I use them.

    To me they seem very similar to Gortons and come in all the same sizes except for the #2. (There's no #1, but the D is the same size.)



    I like the fact that you can swap the orifices. You can also take them out to clean them without having to soak the whole vent. I didn't know you could get a vent with all five sizes,but if you get complete vents in all sizes you can do the same thing. Sooner or later you'll need to replace vents, but the orifices should last forever unless you lose them.



    The Gortons are supposedly better because they have brass floats instead of plastic. I suppose that's an advantage.

    Good option for experimenting

    I bought the 5L and that comes with all 5 orifices for about the price of a 12 pack at Amazon. Looks like you could have a single adjustable and then just buy the #6's and drill it out for whatever size you need.



    I'm not going to replace my Hoffman 1A's with them but they seem to be a pretty good option.

    If you drill them out

    you'll need a way to keep track of what you drilled them to, or you'll have to keep measuring them.



    But it's nice being able to drill them without getting chips inside the vent, isn't it?
