The solution is FFP3 respirators for all staff including support staff and also for visitors, available free for patients able to wear them also

Finally trying some tests with isopropyl alcohol. We know that it can affect electrostatic filtration media from various studies. But I've never tried it myself until now. This first experiment is going to be for about 24 hours. 130 ml of 70% isopropanol in one jar. And 39 ml…

Do you live in an apartment or stay in hotels? Got a "oops, outside air can get you" study. Coming out of Beijing University of Technology - taking airborne transmission seriously. They rented 50 rooms of a building. Did some very cool CFD work - then, be still my heart,

📢🚨 Big update for healthcare & community mask users! 😷 The new EN 14683 standard (v2025) on medical masks just dropped with key updates. Let's dive into the changes 🧵👇 ⚠️ TL;DR: Medical (surgical) masks are NOT PPE! They are designed to protect others, not wearers.
