Didn't work. My mask leaked with it on.
Oh how I really wanted to like this but sadly I had to send it back as it did not work. I have deep set eyes which make sealing a mask around my nose difficult. I had high hopes that this would help solve that problem and make it possible for me to wear all the masks I've bought that don't seal around my nose. Unfortunately this didn't do a thing and with it on, my masks still leaked through the top and fogged my glasses. I know that if my glasses are fogging, then there is air exchange that is not being filtered through the mask and that the mask is probably not doing much to protect me or those around me should I become infected.<br />Fortunately, the return process was easy enough and I got my money back.
