Not snug, does it seal ?
Does not fit snugly, but it seems to make a decent seal when the grey fabric sleeve goes back on.

Great replacement filter. Easy to change the filter
Fits my Blue Air 311 Auto air purifiers very well. The diameter is about 1 cm larger than the original filter but once the outer fabric is in place the fit is snug, no gaps. It was easy to remove the older filter and install the new one. No tools needed.
