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： 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).

Since most of the 3-ply face mask posted in SD are made in China and more likely have China Standard mentioned on the package, here are some information about those Standard...
https://matters.news/@avengermojo...
Basically this is a BFE (3.0 Microns Bacteria Filtration Efficiency ) >95% Mask. It is most likely a 2D flat base with 3 layers. Basically this is considered as a regular face mask that both US and Europe has higher standard requirement then this.
Other test standards go along with this mask will include:
GB/T 15979 for one time use hygienic standard. GB/T 16886 for In-vitro Cytotoxic, Skin Irritation /Sensitization (ISO 10993)
This mask standard is a bit mood because it is BFE > 95% and PFE ( Particle Filtration Efficiency ) > 30% only. Which doesn't match another standard in the US or Europe. But it does include the fluid-resistant test and the flammable test.
These two standard could be confusing but their filterability is basically the same. The only difference is the fluid resistance test with GB19083. In the US NIOSH standard it should be called Surgical, and the Europian standard is Type R. Chinese has 3 levels from PFE KN95 > 95%, KN99 > 98% KN100> 99%. So KN95 is basically the same as N95, N99 similar to KN99 and N100 similar to KN100. Europian FFP1 starting with > 80% FFP2 > 94% and FFP3 >99% .
China only has Surgical Mask which is only 30% PFE and F2100 Level 1 is 95%, Level 2 is 98% and Level 3 is the same with hight fluid resistance. So you are highly unlikely to find ASTM 2 or 3 in the market unless they are US-specific factory.
Europian Standard use their sharp to different the two standards so EN14683 is basically the Medical Mask with no PFE filter just like China YY/T0969 . has Type I, II, III and representing 95%, 98, 99% BFE. And EN149 is the cup sharp respirator with PFE over 80%, 94% and 99%.
The Europian standard surgical fluid-resistant represented by Type R at the end. For example, EN149 FFP2 Type IIR is basically the same as Surgical N95 and GB19083–2010 Level 1.
If we are going outside but not an enclosed environment, a Medical face mask should be enough to stop droplet getting into our system. Even the filter is not PFE > 95% the static of the mask will able to attract virus in the aerosol. If you are going to a room for a longer period of time, a KN95 would be better which is PFE > 95%. If you are medical front line that requires staying in a high viral loan environment for a long period of time, the N95 with a surgical face mask at the front can help extend the usage duration. For ICU it is better Surgical N95 or above and Surgical Face mask at the front or a face shield.

Fix to "something has gone wrong" when trying to checkout:
not sure if is was one or both that helped
1. click checkout first (dont enter coupon yet) and on the next page you enter payment info , it allows you to enter coupon again, it worked
2. also was in incognito mode which may have helped
went for 2 10 packs - almost was going to do the 30 pack to get a little discount but I am betting these will fall in price even further,
since there was a freeship code , figured might as well order 2 , give them a better margin too
In for the freeship code, a wash with price increase. Not hot but I'm not sick either.
