1. Has anyone noticed any difference in the effectiveness of the generic filters as compared to the OEM ones?
I ordered both hypoallergenic ones and standard ones, but after digging into some threads here I learned that the S9 machines don't take two filters. With the ResMed S9 Autoset it's either the standard OR the hypoallergenic. That's different than some machines, like the Respironics, which are designed for two filters. (Just thought I'd reiterate for the sake of others that also didn't know!)
2. Do the hypoallergenic filters reduce the life of the machine due to airflow restriction, and are they compatible with the thinner ResMed SlimLine and ClimateLine tubes? Do they affect treatment or output pressure at the mask?
As always, many thanks!
