Performance of HEPA N95 Nose Mask after 60 days used in Toronto, Canada June 05 2022, 5 Comments
N95 HEPA filter can clean air to keep you health!
I replace the N95 HEPA Filter after 60 days in Torotno, Canada. It is dark on used HEPA fiter in photo.
The left one is a new filter, view from back side
The top one is used HEPA filter, view from front of filter.
I wear the nose mask to super market, watch circus, ride TTC, meet clients, etc.
I feel it is very comfortable with no fog on my glass, easy to breath with fresh air.
HEPA Nose Mask can capture airborne virus February 03 2022, 4 Comments
We use Silver ions sprayed on HEPA H11 for N95 HEPA Filter Nose Mask.
Here are the article about the HEPA capturing the Airborne Virus:
Base on the Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes. Furthermore, on October 5, 2020, the CDC changed its stance on how the virus is transmitted, and now says it “can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours.” In short, the CDC now acknowledges that the virus can spread via the air. That’s a major adjustment of its prior position: that direct person-to-person contact, including via larger respiratory droplets that do not travel far or linger in the air, was the main vector, and that airborne (a.k.a. aerosol) transmission was not a vector, period. Evidence for airborne transmission has been mounting since the spring; to catch up on the course this research has taken, read over University of Colorado-Boulder aerosols scientist Jose-Luis Jimenez’s summary in Time. And it’s worth noting that on September 18, the CDC published—and three days later retracted, citing errors in an internal review process—a version of its guideline that stated flatly that inhalation of aerosolized respiratory droplets “is thought to be the main way the virus spreads.”
Back to purifiers: The virus that causes COVID-19 is approximately 0.125 micron (125 nanometers) in diameter. It falls squarely within the particle-size range that HEPA filters capture with extraordinary efficiency: 0.01 micron (10 nanometers) and above. Many media outlets have incorrectly stated that HEPA filters don’t filter below 0.3 micron and therefore could not capture airborne coronaviruses. That’s wrong. This NASA study of HEPA filtration is quite technical, but the graph on page 7 and the preceding paragraph do a good job of explaining why HEPA filters are actually most efficient—almost 100% at 0.01 micron—at capturing ultrafine particles below the 0.3-micron HEPA test standard.

Mail from The First US Customer for N99 HEPA Filter Nose Mask February 03 2022, 6 Comments
I received the letter from our 1st US Customer Mr. Bob:
Yes I have received the nose mask it is nicely packaged..
.Thank you also for the partial refund of 25 CAD... for the shipping cost
And thank you also for a brief description of how I might be able to open up the mask to have
access to the filter...
I am considering the sale final since I am experimenting with it and will keep you in mind for doing business with again
I am hoping that this mask will meet my expectations in preventing the triggering of allergic reactions due to nuisance dusts
first I have tried it just the way it is and will see if I am not sensitive to the carbon and silver in the filter part if I am I will take that part out..
and I am impressed with how it comes apart and reassembles so that you can take the carbon filter out if I want to..
I am hoping able to use it with my glasses so that the lenses do not fog up
like they do when I use the paper type duct bill masks that leak around my eyes when I exhale...
I am hoping that this one will provide a superior seal since it goes right up against your nostrils and I can exhale out of
your mouth when using it... this is another reason why I considered purchasing it.
It is a smart design that I could not seem to find anywhere and was thinking about trying to making my own by gluing a filter on to a sleep
apnea when I was shopping for parts and fortunately a web search brought me to a link to this product you offered on your site...
