I ordered this because of COVID worries, then I worked for a full day in a skid row alley in a major city. During the entire day, I breathed only fresh air. When I removed it for a second to scratch my nose, the air hit me with absolute disgust of smell so bad that I could feel and taste it. I quickly put the mask back on and took some deep breaths to clear my lungs and senses of taste and smell.
Now I did catch COVID indoors with a close family member so we are isolating. I'm wearing the mask all day, continuously, and it's become a normal part of my being. I use the enclosed charger cord (it's a low voltage cord) plugged into a battery in my pocket so I can leave the voice on all day, too. Using voice really runs down the battery in the mask but it seems to use little from the battery in my pocket.
I love it. With my work in hazardous places sometimes, I'm incredibly grateful for it. I feel safer dropping into indoor wifi spots (cafe's etc) to do my reports between jobs.
I can't say enough good things about it. I'm a smallish woman and now that I've worn it so much, I feel naked without it. It's very lightweight and comfortable.
My ONLY complaint is the cost of filters. I want to buy the masks in bulk, one for each family member and employee but the filter costs are prohibitive. Is there a way to buy them in bulk to make them reasonable? Thanks.
