All this Cpap stuff is ridiculously priced.
I am going to go find a furnace filter that looks like the same material and spend $15 and cut out about a hundred of these little rectangles.
Has anyone found a cheap way to replace their filter?
Or is there anything wrong with my idea?
[cut out about a hundred]
The edges of the hypoallergenic filters that I purchased with my Cpap are sealed shut. That is likely necessary. If you cut out filters from those larger furnace filters, this might expose tiny particles from inside those filters that migrate out along the edges where you cut . Those particles could end up being sucked up into your cpap and blown into your lungs.
Foreign bodies in your lungs could cause some nasty problems. I don't recommend it.
