Hey guys don't want to burst your bubble, however, what you are talking about is not a filtration test, but one that has been propagated by social media. You have sadly been misinformed. The only actual liquid barrier test that is performed on respirator masks is for a small classification known as Surgical N95's, which are considered medical devices by the FDA. Also, liquid barrier protection is rated by ASTM and not NIOSH. Your standard N95 from 3m or Honeywell is not designed for liquid barrier protection and the ability of it to hold water has zero impact on filtration. I emailed Powecom after seeing some of these posts just to be sure and recieved the following back:
:
IT IS NOT scientific to test qualified KN95 masks by pouring water into them. The dripping test is just a rumor. Firstly, water will destroy the protection ability of the melt blown filtering layer, that means: Water will destroy the effectiveness of the face mask; Secondly, too much water has weight (universal force[Laugh]) , so too much water will drip. Also, : The first layer of nonwoven material can let O2 (= oxygen ) pass through the face mask. That is why, the 1st Layer of face mask cannot 100% block water, especially when there is too much (for example, a cup of Water , too much water !!) pour in the face mask. This is not a scientific test and should not be used. Below are links from actual testing reports from the NPPTL that may be helpful Guangzhou Powecom Labor Insurance Supplies Co., Ltd.KN95GB262699.2898.962020-211.1pdf icon [cdc.gov] Guangzhou Powecom Labor Insurance Supplies Co., Ltd.KN95GB262699.5698.182020-303.1pdf icon [cdc.gov] Just want to make sure you guys have all the information. N95's are not for liquid barrier protection and neither are KN95's. The only liquid barrier protection masks are real ASTM surgical masks and Surgical N95's, which right now should be reserved ONLY for healthcare professionals. |
Statement for the Medical Device Respirator recalls in Canada
Guangzhou Powecom Labor Insurance Supplies Co., Ltd hereby declare that the following two importers are not our purchasers.We have not found any information about the relevant companies in the sales records. Our company has an export license. All exports in our company's name are genuine.
There are many fake products on the market. The products that fail to pass the inspection in Canada are not exported by our company. Obviously these are fake.
Our main task in February, March and April is to provide the Chinese government with a large number of high-quality and qualified masks.We've been on the EUA list since April 3 . In fact ,CDC has always tested the quality of all respirators,in order to ensure that all the respirators imported to the United States are safe and up to standard. The following four test reports were issued by NPPTL and can be read on CDC website๏ผ https://www.cdc.gov/niosh/npptl/R...SULTS.HTML
Government of Canada has issued a RECALL on these products.
Health Canada has determined that certain respirators that do not meet performance standards may pose a health and safety risk to users when used in a setting that requires 95% filtration (such as a health care settings).

Curious if anyone else has seen this?
Sure I'll take a pic later today.
Btw, does anyone know a legit place to get the Harley ones on the FDA list?
I've been considering KF94 from Korea since Korea is now allowing each factory to export between 10%-20% but have to find a reputable Korean distribution company. If anyone knows any for KF94 or Harley please share. Thanks.
also bought some Harley from colorsheild health however they were very small. I gave some to my mom without commenting and even she said they were too small
"General" KN95s available at your local store or online are most likely garbage.
But I'm not jumping on this deal until people report on the quality.
Fit is an issue, as ear loops are never as airtight as straps.

When it was new N95 can filter/capture 98% of particles. But after disinfecting with alcohol and drying, the filter/capture drop to 60%. And as we know, KN95 is worse than N95 (especially from little known manufacturer with unpredictable quality) since it allow 10% of leakage, so after wash, not sure how much effectiveness it will leave.
In short, washing the mask was much worse than natural "aging" like just let it air out.

About Harley, I got some from color shield, but 3 out of 10 had welding issue. Their earloops were just loosely touched on masks.
I haven't done any researches on KF94 and not sure if all KF94 are with equally good or acceptable qualites.
