So .. it's been smokey all week here and I am allergic to something in the air. The CPAP machine has a tiny filter on it, but why not upgrade it to a standard size one? My thoughts exactly. Storage box was $10, top end filter $36, plus tape and a hot glue gun, and an hour or so .. (<$60 CDN). I will let you know how it goes!
- Step 1 - buy storage box and filter and silver duct tape .. already had the CPAP machine .. besides, it was 6am and nothing was open except Lowes ..
- Step 2 - use hot glue gun and sharp knife to modify box a) cut/melt electric cord access hole b) cut/melt air hose access hole, c) cut out lid to attach filter to.
- Step 3 - tape filter onto the modified lid. Make sure the air flow directional arrow is pointing the right way (toward the CPAP machine).
- Step 4 - assemble and test. Looking good. Took about 1 hr travel and 1hr to assemble. Easy peasy.
Notes
- I could have taped and sealed the lid onto the box, but I think the filter will work fine without a 100% seal, much like your furnace setup.
- In order to turn off the machine, I need to remove lid to access to the on/off button. Also to clean the hose, will have to remove the lid, disconnect the machine and remove it all from box and then clean the hose/box together.
- The filter claims to have a 3 month lifespan, but so little air is going to be pulled through it - basically just what you can breathe in each night -that I think it will last much longer.
- Night 1 went smoothly: 7 hours with no allergy symptoms noted. Yay
