Generic Outlet Bacteria Filter (1 Pack)

No explanations anywhere for "where" it can be installed on the air hose line. (Especially, when HMS is already in use) I bought one just in case I need it.

For those who want "a little extra" filtering, this filter is for you. It fits in-line between your hose and CPAP mask (or your "humidity tank" and CPAP hose - let your machine/"physical comfort" dictate where you install it!) and provides additional particulate filtering - definitely useful for people like me who have SEVERE allergic reactions to "airborne particulates" (pollen, dust, etc.). While it's recommended to change the filter MONTHLY, you can keep it installed LONGER, just monitor the color of the "air intake" side of the filter - when it gets "dark gray" or DARKER (compared to the filter's "output" side), you know it's time for a fresh filter. It can take time to get used to having it, but once you're used to it, you won't really notice its' "presence". Furthermore, it ** DOES NOT AT ALL ** impede air flow/pressure from your machine, even when it gets "dark" (see above). I ** DO INDEED ** recommend this product for ANYONE who uses a CPAP!
