They chose the Aura. 💪🏼 @michael_hoerger likely has a more in-depth understanding of this psychology. But it might be a strategy worth trying. Stay safe out there folks. 🫶🏼

Instead of positioning the healthcare provider with a choice to mask or not, I put them in a position to choose which mask they would like. People want the freedom to choose. Instead of the choice between masking or not, trying giving them the choice of which mask to wear.

😷 in healthcare settings. 🏆Success story🏆 (A strategy worth trying) At my routine mammogram appt this morning I approached my technician (wearing a surgical on her chin) with these 2 masks outstretched. “Can I upgrade your mask with one of these for the next 5 min?”

@CriticalAerosol Oh, and I forgot that I passed in a regular ear-looped @BreatheTeq. This is uncommon, and shouldn’t be taken as any advice. Just sharing info.

We have some higher risk events coming up & doing quantitative fit testing offers an added layer of confidence to our mitigations. Grateful for a local CC family who borrowed these machines from @CriticalAerosol & opened their garage to others. Keep taking care of each other.

I continue to pass perfectly in the Aura 9210+ (white straps). I was excited to add another option with a perfect score wearing the Zimi KN100.

Zimi mask (7711) passed with a perfect score on my 7yo, 9yo, & 11yo. They were curious how it would test without the plastic frame inside. Failed miserably.

Date night 💖(with the kids) Annual 😷 testing with 2 portacount machines to ensure we’ve got the best fit, especially with growing kids. A few observations worth sharing … (Shout out to @CriticalAerosol for sharing his machines with our community) 🧵

This!! 🎯
Every school has a policy to protect those with a peanut allergy (1-4%), but 8.2% of American children have Long Covid (climbing every day) and 100% are susceptible. Children didn’t consent to having their lifespan cut in half or being sentenced to a life in bed. Clean the air!

I'm not gonna link to the actual post cuz I don't want to give them engagements. It's buried in my comments. If you want to fight the trolls share this next tweet instead about the youth video contest we are launching to help get the word out about clean air in schools.

I have reached a new status level! My trolls made me a customized AI video. They put my name in their video, with a special hate message just for me! I am so flattered! Unfortunately, AI-generated videos are not allowed in our youth video contest. Sad. https://t.co/n99bOnisNI

Awwwee! I love when my two worlds of clean air advocacy and educational neuroscience collide. I can't wait to hear what you think!!
As a person who was a geeky kid and college computer science major, I am really excited to have this book by @Liesl4CleanAir arrive today. It's meant to be a gift for my #Math #Teacher cousin but I get first read. #Science #Teaching #STEM #STEAM
