Im torn betwen the equi-resp and the silver horse care mask. I was all set to buy the Equi-resp but after talking to a couple people (Some pro girls) they told me its better to have the mask that DOES NOT seal around the nose and that it allows the "bad air" to exit the mask quicker. 

HELP! 

Flexineb if you want the best one. 

Equi-resp if you want the second best. 

I bought the Silver Horse Care one 

Maybe it’s not the same as humans - but my son has a nebulizer. His doctor had told me that it didn’t matter which nebulizer I bought-they all do the same thing. My son’s masks have holes in them. I think it’s for the exhale.
