a damn shame that no one seems to give a shit about masking up amidst an airborne pandemic. guess it's gonna be up to me to try and make proper PPE fashionable by serving cute looks with my new mask (selfie ec)

it looks like a 3M 604 exhalation valve filter will fit on it with a little modification, so the PD-100 can be given proper source control! also, it looks real good with the anorak vest that i waterproofed with beeswax. very post-apoc chic. (selfie ec)

I was right, adding an exhalation valve filter was pretty easy. A 3M 604 with one of the mounting hooks broken off and a bit of fishing line, and it's good to go. Now all I need is an o-ring to put around the base of the port cover and this will be fully sealed for source control (selfie ec)

O-ring acquired. It seems to hold up with minimal leakage under an impromptu positive pressure test, so I think I'm all set.

That looks awesome!

I’ve been thinking of waterproofing some things with wax. Did you use solid or melt the wax to put it on?

@McKenna i melted the wax in a little double-boiler (glass jar in a saucepan of water) on the stovetop and brushed it on, heating it with a hair dryer as i went to get it to melt and thoroughly impregnate the fabric. took about 8oz of beeswax, mixed with some butcher block oil (rice bran and lemon oil) in a 20:1 ratio in order to do the whole thing. if anything, the wax went on a little too thick; i wanna send it through the dryer in a pillowcase to remove some of the excess.

@McKenna i'd probably recommend using a rub-on block of something like otter wax for items you care about. this was more of an experiment on a thrift-store find, using beeswax i found at the local hardware store. brushing it on worked nicely to soak the single layer of fabric in what i intend to use as a raincoat, but it would definitely soak through into the liner layer of a multi-layer garment, possibly ruining it

I actually have a block of Otter Wax from a project that I never finished. Might try it on something thrifted for experience first to get the technique down.

I was trying to make a pair of waterproof (resistant?) canvas boots a few years back and bought all the stuff ahead of time but stalled out in the stage where I was sewing on the soles.

@Squiddy need to get myself a mask but i dont know what to buy eicnenfir aaaaa

@lyncia What are you looking for? Full- or half-face? I've been using a 3M 6200 (available at most hardware stores) with 7093 P100 filters for the past 8 months or so. My new mask is a Strong ST-S100 (sold in the US by Parcil as a PD-100), which takes 3M filters or its proprietary screw-on ones with included adapters. Pretty much any elastomeric mask with N95 filters is gonna give you good protection, with P100 filters being even better. There's also stuff from MSA, Dentec, etc.

@Squiddy half face would be fine but full face aesthetics are a good vibe i like
ill go with half mask for rn

@lyncia I'd recommend 3M or 3M-compatible masks, since you can find them and their filters basically anywhere. i'm also using 3M's model 604 filter on the exhaust port of the mask for source control, to filter my exhaled air so I don't spread anything I have. Most elastomeric masks AREN'T designed for source control, so this is something to watch out for.

@lyncia There have been a few new SC masks released since the start of the pandemic, though, like the MSA Advantage 900 or the Dentec Comfort-Air. The Advantage 900 features a voicemitter diaphragm, so you aren't muffled as much when speaking. Those two masks, however, operate so you breathe in AND out through the main filters, meaning they can get really humid as moisture gets trapped inside the filters and humidifies incoming air.

@lyncia The separate filter on the exhaust port, like with the 3M, means you preserve one-way airflow, keeping moisture down. It does come at the cost of severely muffling your voice, though, as the 3M masks lack a voicemitter. My ST-S100 doesn't have this issue, despite my jury-rigged exhalation filter, thanks to its built-in voicemitter.

@lyncia Another half-mask respirator i've heard good things about is the GVS Elipse. It's pretty light and compact and has source control variants (including proper one-way airflow on the P3 filter model). The main issue is that the filters aren't readily sold most places, so you'd have to order replacements online.
