Disposable mask quality control inspection service

Inspection items of various face masks quality inspection: filter efficiency test, quality test, tightness, air tightness, active carbon component test, microorganism test, ethylene oxide residue, dust resistance efficiency, filter element test, etc.

From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: “gb2626-2006-kn100” national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.

Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level A. The corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 μ g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 μ g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350 μ g / m3) and grade A are used when PM2.5 concentration reaches 500 μ g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75 μ g / m3, and make the air quality in the inhaled body reach good or above level.

Some common factors for disposable masks quality control:


Measurement of product

GSM check of each layers

Basic function check

Smell test

Application check

Rub test for logo/fabric

Pull strength test for earloop/seam

Fire test: the meltblown fabric is fireproof

Waterproof: the meltblown fabric is waterproof

Electrostatic adsorption test: the masks with meltblown fabric inside will attract small pieces of paper

Light transmission test

Breath test with a mask test

Packaging & Labels

Carton drop testing

Coronavirus Impact on Manufacturing from China

Unless you are living under a rock, you may have heard about the coronavirus originated in Wuhan, China. The Hubei province, and much of China, is in complete lockdown with many businesses closed, and people staying home as the government extended Chinese New Year for a few days until the epidemic is under control.

This should obviously have an economic impact, at least in the short term, for the next few weeks or months since people are asked to stay home, and a lot of goods consumed is manufactured in China. And indeed, some companies are announcing delays due to the virus.


It’s difficult to find updates of delivery time from companies actually based in China, potentially because they need to check with their sub-suppliers to check whether they are affected by the virus or not. But I’d assume if you have purchased products from Aliexpress, GearBest, GeekBuying, and the likes, and if the parcel has not left China yet, you won’t get it anytime soon unless there are stock at the suppliers’ warehosue. By the way, the virus needs a carrier (e.g. living creature) to stay alive, so there’s no risk to get infected with the coronavirus from a package since it takes several weeks to arrive at its destination.

So far by Feb 1st,2020, Chinese government has officially extended the Lunar Spring Festival to Feb 10th,2020. And only some important retailed shops, foods market, logitic company, mask factories etc are allowed to run first. As I witness, some Chinese companies will have their employee work at home for the week of Feb 3 to Feb 7th, so I believe they will update you the situations when you talk to them if you buy from them.

So beside the human toll, there will be an economic impact, but only time will tell just how much this impact will be.
