The inlet filter cleans room air on the way in. The in-line filter guards the boundary between the machine and the wearer, catching bacteria and fine particulate in the airflow and, just as importantly, stopping anything travelling back down the tube toward the blower. That matters in three situations in particular: where a machine is shared between users in a clinical setting, where the wearer has a respiratory infection and the circuit would otherwise be contaminated, and where a machine is loaned, hired or sold on. It is also the cheapest way to protect an expensive device from the inside.

It is easy to dismiss as trim, and it is not. Without it the filter is not held flat against the inlet, so air takes the path of least resistance around the edge of the filter rather than through it. The machine then draws unfiltered room air straight into the blower and down the hose. The cover is also the part most often lost, because it comes off every time the filter is changed, it is small enough to slide behind a bedside table, and it travels loose in a bag.

It is easy to dismiss as trim, and it is not. Without it the filter is not held flat against the inlet, so air takes the path of least resistance around the edge of the filter rather than through it. The machine then draws unfiltered room air straight into the blower and down the hose. The cover is also the part most often lost, because it comes off every time the filter is changed, it is small enough to slide behind a bedside table, and it travels loose in a bag.

The cover comes off at every filter change, which is monthly at most intervals, and it is a small light piece of plastic that is easy to put down and lose. It also travels badly: packed loose in an overnight bag it can be left behind in a hotel room or crushed against something heavier.\u003c\/p\u003e\n\u003cp\u003eThe consequence is that a machine ends up running with an open filter recess for weeks, which quietly undoes the whole point of filtration and leaves dust and pet dander accumulating inside a blower nobody can clean. Buying a spare cover costs very little against a machine that has ingested months of unfiltered air, and it means a lost cover is a nuisance for one evening rather than a problem for a month.\u003c\/p\u003e\n\u003cp\u003eThe twin pack suits a household with two machines, or anyone who travels with theirs and wants one permanently in the bag.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eHolds the filter flat against the inlet\u003c\/strong\u003e, which is what forces all incoming air through the filter rather than around it.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eClips on and off without tools\u003c\/strong\u003e, so a filter change takes seconds and the cover goes straight back.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eFits AirSense 10 machines\u003c\/strong\u003e, seating in the filter recess on the side of the device.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eSingle or twin pack\u003c\/strong\u003e, selected from the options on this page, with the twin pack covering a second machine or a travel bag.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eReplaces a lost or broken cover cheaply\u003c\/strong\u003e, rather than leaving the filter recess open until a machine service.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eWipe clean plastic\u003c\/strong\u003e, cleaned alongside the machine housing.\u003c\/div\u003e\n\u003cdiv class=\"pw-box\"\u003e\n\u003cstrong\u003eAlvera own brand\u003c\/strong\u003e from Elarix Medical, supplied direct and individually referenced so reordering is by code rather than description.\u003c\/div\u003e\n\u003cdiv class=\"pw-alert\"\u003e\n\u003cp\u003e\u003cstrong\u003eCheck the machine before ordering\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis cover fits AirSense 10 machines.
