Does :dc Microparticle Stopper Mask has certify by international Certificate
Yes, :dc 3D Mask has certify by varios national strandard，such as EU FFP2, Taiwan, Korea, China.
EU: EN149 FFP2
Taiwan : PM2.5 mask CNS 15980 A class (passed 8 major test items.)
China: GB/T 32610 A Grade PM 2.5 mask
China: KN95 Mask Certificated
Korea KF94 Mask Certificated
:dc mask also done many tests in USA, Japan, China and Taiwan NCTU Lab, please refer https://www.dctpro.com/en/test_reports.php for all our test reports.
What different between medical mask and :dc mask?
All :dc mask serire provide N95 / P95 protection, :dc mak provide better protection than medical mask.
Most general medical masks use electrostatic melt-blown materials, which filter and protect particles larger than bacteria (PM 3 ), but the particles smaller then PM 2.5 are harmful to the human body (particles below PM2.5 are collectively referred to as PM2.5). In addition, the filtering effect of electrostatic materials will begin to decline with the moisture of breathing when worn, and electrostatic filter materials cannot effectively filter oily fume particles (for example: oil fumes, exhaust fumes from automobiles and motorcycles... ) and cannot effectively block oily particles. The electrostatic filter material is also not washable, spray alcohol for disinfection.
:dc mask provide over 95% protection of PM0.075 particles. The nano-film filter material can protect fine particles and oily areosuls particles at the same time. It is suitable for daily air pollution PM2.5, work occupational environment and germ health protection. Gram particles The mask is comfortable, breathable and has high-efficiency filtration at the same time. It can be washed and reused. It is an all-round protective mask.
What is the difference between :dc Microparticle Stopper and other N95 masks?
There are 3 grands of mask , which divide as N Grade (non-oil Proof), R Grade (Oil Resistance) , and P Grade(oil Proof).
The P grade is the highest-level mask, and its protection is better than the N grade mask.
The "N" of the N95 mask stands for non oil proof, which is the protection of "non" oily particles.
Oily particles include exhaust fumes from automobiles and motorcycles, factory fumes, kitchen fumes, barbecue fumes, etc. Nowadays, as long as you go out, you will face the threat of oily pollution particles.
:dc mask provide protection both for "Oil Proof " and "Non-Oil Proof" protection, its FFP 2 certified. And has also passed the standards for the protection of oily particles in many countries, and has been tested by Jiaotong University-Environmental Engineering Institute. Effectively filter 95% of heavy metal particles in the atmosphere.
:dc mask is an all-round protective mask, which can be used for occupational work protection, kitchen fume, air pollution PM2.5 and influenza allergy protection. The mask can also be disinfected and washed for reuse.
