Review on 🔒 COAST KN95 Face Masks Individually Packaged by Robert Yates

these days. Most municipalities have adopted and banned N95 paper masks with an exhalation valve, so this type is your only option if you don't want to use a reusable cloth mask or those really regular flat surgical masks (which don't seal well). These masks seal very well due to the shape and the aluminum strip in the bridge of the nose. Ensure very good particle shielding during inhalation. One can only speculate if they are actually doing anything for COVID (and it seems that the "science" about masks isn't entirely clear). But compared to most options I've tried, they're better for the following reasons: 1. There's no exhalation/purge valve, so they're "legal" in very authoritarian states like CA2. Aluminum nose bridge provides a custom fit and a tight seal3. Ear loops are much easier to put on and take off than head and neck masks (e.g. 3M). If you wear a hat or glasses, it's MUCH easier! Some points to be aware of: 1. There is no foam seal on the inside of the nosepiece, so there may be some leakage when you exhale. This will be directed towards your eyes and will cloud your glasses.2. Since they don't have a vent valve, they don't lend themselves as well to sanding/painting and similar tasks as masks with vent valves (which are usually more expensive). This is because the exhaled air gets past your nose and into your eyes, clouding your glasses3. The thickness of the N95 mask, when properly closed, will definitely cause some breathing difficulties. Running with one of these, I definitely feel like I'm taking in less air with each breath due to the extra effort of pushing it through the filter material.
