I finally added a battery to my @SmartAirFilters QT3 using this brilliant hack from @CC14_CC14. It really just takes a small jeweler's file against the lid to make the edit. (Also remember to file an opening into the resting lip on the actual unit, too) 
I made my wiring hole to the right of that little center clasp out of laziness. (It is indeed haphazard, I'll file it flush later)
I bought the same T-CORE battery. Wow is it satisfying to be able to actually close the lid on it. #perfectfit inside that qt3 air purifier compartment. TY for your service in figuring that out
I wear an N95 respirator to protect myself, my patients, my colleagues and my family. Blocking inhalation and exhalation of potentially infectious particles just makes sense during a respiratory pandemic. #PerfectFit on the PortaCount #SayNoToSafetyStewardship #FreshAirWeCare
Because a fit factor of 5 (20% leak) - when quietly breathing through a surgical mask - isn’t respiratory protection.

My mask solution earlier in pandemic was a mask brace to optimize my fit. Have since switched to N95s to optimize filtration (respirator material meets higher testing standards) and function (N95 easier to put on, more comfortable, more breathable).
