changed out my 3M respirator pink disc p100's to a pair of black cartridges I think they work great, worth the investment ☑️ HOWEVER, it NEEDS to be said and noted that 3M respirator cartridges are heavier than I thought they'd be. That extra weight caused me some head/neck strain and stretched the fit of the headband in a way than I wasn't used to just something to consider disability/accessibility wise if y'all have have neck and/or head concerns #wearARespie #WearAMask #Respirator #MaskUp #COVIDIsNotOver #disability #LongCovid #ChronicIllness #StillCOVIDing
