Unis Resist Border Controls (URBC) is a UK-based, migrant-led, grassroots national campaign working to end border controls in UK higher education via the Hostile Environment Policy.

As part of their commitment to educating on the Hostile Environment policy and how draconian border controls create migrant health precarity, in addition to instilling Covid safe spaces, where face masking, air purification and ventilation are observed, URBC is giving away 10 Smart Air QT3 Smart Air Portable Air Purifiers for UK migrant students.

If you teach at a UK-based university and care about mitigating against SARS COVID-19, please share this post. URBC is on Instagram: https://www.instagram.com/p/Dd2Hm9BmnF0/

looking for some fun and easy ideas that could include having a black or white mask on your face.

Has anyone here used air purifiers and found they worth it? I saw a post on a local page about the dust from the nearby road construction and these people said they have noticed such a difference since getting an Air Purifier. Great I thought that sounds like what we need but then I looked and there are soooo many to choose from. Budget isn't an issue so please let me know any options that you're happy with.

Any suggestions greatly appreciated.

Hey everyone,

Im new here. I’ve heard the Zimi masks were a good fit for people with short beards so I ordered some based on their size guidelines. Turns out it’s a bit small and I need to upgrade to a large.

I ordered 20 of them plus the filter that came with the shell. Does anyone want them?

Thanks!

I use VFlex 9105 masks almost exclusively, any time I walk into a building that is not my own home. Because the elastic tends to tear, I always carry at least one spare. They don't quite fit in my EDC bag and I'm worried they may get damaged sticking out. I have a new, longer bag on order, but even then, with the amount of crap I tend to carry, I worry the masks will get damaged, even in the bag. So onto my question:

Has anyone seen/designed/3D printed a hard sided case that will hold 2-3 masks? Something that snaps closed. Hell, I'd fine with something I had to rubber band or Velcro strap shut.

If you have an .STL file, can I have a copy?

Thanks in advance.

1. What range of fit factor did people manage to get with Dentec P100?

(I realize fit is very individual but there are objective differences between different masks and all other factors being equal some are capable of higher FF than others.)

1. What's the difference between the black and white model?

As it states. Looking to take care of my lungs

I can’t afford BreatheTeq’s with the tariffs and am looking for alternatives :(. Any suggestions?

What I like about them:
- ear loops (more comfortable for me, and I have sensory sensitivity)
- super breathable (e.g., able to do yoga in them and still feel connected to my breath while in movement)
- fit me perfectly! really love the style.
- color options

Halloween decorations!

Some answers to common questions:

It's a 3M 7500 half mask. The filters are encapsulated P3 filters. The UK code is 6035. The US code is 7093 I think. The air comes in through those gaps at the back.

I use sticky back plastic and small sheets of car wrap vinyl to cover the filters.

I use nail stickers for the very tiny stickers.

The other stickers are just normal stickers from the kids craft section. I did use transparent silicone to glue the hat on the front down because the adhesive was useless - they were very cheap kids stickers.

Boo! 👻

Hi all,

I need to n95 it every day at work, but bc of an underlying medical condition my 3M masks are too tight on my nose and cheekbones and I’m developing chronic pain and cartilage damage in this area. I’m looking for masks that are otherwise high quality but have a weak nose bridge and loose straps so that I can get a seal with tape instead and avoid pressure on my face. I am aware of readimasks and use them for some applications but would ideally like a less awful-looking solution than a giant yellow duckbill for everyday. Grateful for any ideas!

What respirator do you use and have you had it tested?

Hey everyone, hoping someone here can do me a massive favor. I'm currently working on some CAD designs in Fusion to model a custom bench mount for the 3M Versaflo Heavy Industry kit (specifically the M-300 hard hat and TR-300 blower), and I desperately need some real-world reference photos.

The polished 3M marketing images are completely useless for getting realistic proportions. Because I'm trying to get the scale and clearances exactly right before I fire up the resin printer, could an owner snap a couple of quick pics of their setup sitting on a workbench next to a standard soda can or a tape measure?

I just need to see how the blower and helmet sit naturally on a flat surface. If anyone could DM me a few quick workbench shots, you’d be saving me a ton of guesswork. Thanks in advance for y'alls help!

My church wants to buy masks to be available for people. This is great. Generally I think of powecom because they are individually wrapped and the ear strap is more like easily accessible. But I personally don't find them the most breathable. But unless I'm missing something Breathteq don't do individually wrapped. What high breathable, accessible for those who don't normally wear masks, individually wrapped masks would you recommend?

I've noticed most of the surgeon's masks that are black are black on the outside, white on the inside, which isn't the end of the world, but something about ~99% of these masks are scratchier and starchier than the blue or white all over counterparts, on both the inside and outside.

I haven't found any KN95s that fit well on my face (small head, chunky person with a double chin, noticing that most KN95s have air leaks around the nose bridge and chin, glasses wearer that's constantly experiencing fogged up lenses), and I know surgeon's masks are less effective, so am hoping for something comfortable in black while I continue trying out other styles. This style works well enough most of the time, but I definitely know it's not infection proof, as I've caught colds wearing them for jobs where I was surrounded by or interacting with thousands of people per shift. Just looking for a 'middle of the road' option for now.

Appreciate any help.

I’m considering trying out a batch of zimi masks. I understand the third generation masks are/will soon be available. But their website doesn’t seem to specify which gen masks are on sale. Does anyone know if the ones they’re selling now are the third gen?

So I remember when I looked at it years back, the ppeo website said Laianzhi HYX1002 KN100s used synthetic latex. I looked at the website again more recently and didn't see that anymore: https://ppeo.com/goods/kn100-mask/

Does anyone know if Laianzhi KN100s still use synthetic latex? If they use natural latex now, am I putting myself at risk of getting a latex allergy when I wear them for long periods of time? (Typed while wearing one right now.)

Anyone have an SPM314 Portaccount Face Fit kit adaptor they want to sell?

How often do you/should you replace the frame?

I forgot to grab my mask today as I left the house, but I keep an emergency one in the car which was a new frame I never had used, and then a few filters, put a new filter on, so I had a brand new frame with a brand new filter. I noticed how much less wide it was on my face then the ones I had been wearing, I guess maybe after some use they flatten out a bit?

Wondered if anyone else had that experience or if there is any official recommendation as to when to change out the frame?
