Excuse me about the 8822 mask, which is the PPPF2 standard. But the box description says that it can

Hello! Glad to answer for you, there is no PPPF2 standard mask yet, what you are referring to should be FFP2, please make sure you are buying **. The 3M 8822 mask has no protection against harmful gases, and is only effective against particulate matter in vehicle exhaust emissions, and has no effect on gaseous substances (such as hydrocarbons, sulfur dioxide and nitrogen oxides) emitted by automobiles.

The composition of automobile exhaust is very complex, including carbon dioxide, certain heavy metal compounds, such as lead compounds, carbon particles (among which diesel vehicles are the most obvious, because diesel fuel is more likely to crack under high temperature and high pressure to produce a large amount of black soot visible to the naked eye), and insufficient hydrocarbon gases or vapors and oily particulate matter, as well as a small amount of carbon monoxide, nitrogen oxides and sulfur dioxide.

Anti-particulate matter masks with activated carbon with organic gas and vapor odor reduction function can reduce the odor of automobile exhaust, such as 3m 8247 masks.

We hope you are satisfied with the above reply! If you still have questions, please feel free to ask the company.

8822 is an FFP2 particulate protective mask that complies with the EC EN149:2001 standard. This mask is designed to protect against very fine industrial dust, with a filtration efficiency of more than 94%, and is suitable for hot and humid environments or long-term wear protection.

This mask cannot be used to protect against organic vapors, if you need to protect organic vapors, please choose 3M products organic vapor professional protective masks.

The characteristics of 8822 are that it is worn for a long time and filters very fine dust, which has a certain protective effect on automobile exhaust but cannot protect against odors. If you need to protect your car from exhaust, please choose a professional protective mask with 3M organic vapor or call 400-666-5955 to ask a technical specialist for a recommendation. Thank you!

No, no mask can prevent this, you should at least choose a half-mask, and if you are better, you will have a full mask.

Hello! We are glad to answer for you, 3M 8822 protective mask has obtained both European FFP2 level certification and China KN95 level certification.

The European standard requires testing for both non-oily and oily particulate matter, and the FFP2 level represents 8822 with a filtration efficiency of 94% for both oily and non-oily particulate matter. In China, 8822 cannot fully meet the requirements of China's KP95 level, and has obtained KN95 certification, that is, the filtration efficiency of non-oily particulate matter is not less than 95%.

There are no authoritative studies on the composition of medium-oily and non-oily particulate matter, which can usually be treated as non-oily particulate matter when protected.

We hope you are satisfied with the above reply! If you still have questions, please feel free to ask the company.

Hello! I'm glad to answer for you, both of which are organic vapor odor and particulate matter masks.

The difference is the protection level, 8577 meets the American NIOSH standard P95 level, which can filter both non-oily particulate matter and oily particulate matter, and the minimum filtration efficiency is 95% under the test conditions specified in the standard;

9913V has obtained China LA certification, in line with the Chinese standard GB2626-2006 KN90, only suitable for the protection of some non-oily particles and the reduction of some organic odors, relatively speaking, the protection level will be lower, some protection functions are not as comprehensive as 8577, but ** will be relatively cheaper, it is recommended that you choose the right mask according to the actual protection needs.

Both of these are organic vapor odor and particulate matter prevention masks.

The difference is the protection level, 8577 meets the American NIOSH standard P95 level, which can filter both non-oily particulate matter and oily particulate matter, and the minimum filtration efficiency is 95% under the test conditions specified in the standard;

Hello! We will be happy to answer for you, particulate matter can also be divided into non-oily particulate matter and oily particulate matter according to the type. Different masks use different filter materials.

On the one hand, the filtration effect is related to the particle size, and it is also affected by whether the particles contain oil. The 3M mask complies with the GB2626-2006 "Respiratory Protective Equipment - Self-priming Filtering Anti-Particulate Respirator" standard, which classifies and classifies anti-particulate filter elements. The filter material is divided into two categories: KN and KP, K is the meaning of anti-particles, KN is anti-non-oily particles, and KP is anti-non-oily and oily particles; There are 3 levels of filtration efficiency.

The efficiency of KN or KP90 is 90%, the efficiency of KN95 or KP95 is 95%, and the efficiency of KN or KP100 is that the most difficult particles to filter are used as the test medium. The difference in grade means that the filtration efficiency is different, and there is no difference in the particle size of the particulate matter. If protection against highly hazardous particulate matter, such as lead dust, is required, a filtration efficiency of KN95 or higher (95% or more) is usually required.

For protection against low-hazard particles, low-efficiency filtration can be used.

Non-oily particulate matter is very common, including solid dust, smoke, water-based fog, etc., such as coal dust, rock dust, cement dust, acid mist, paint mist, etc., and microorganisms also belong to non-oily particulate matter;

Common oily particles include oil smoke, oil mist, asphalt smoke, coke oven smoke and particles in diesel engine exhaust.

KP media can also be used to protect against non-oily particles, but KN filter media cannot be used for protection against oily particles.

We hope you are satisfied with the above reply! If you still have questions, please feel free to ask the company.

3M masks are commonly used into KR and KN series, KR series can filter oily particles, KN series mainly filters non-oily particles, but cannot filter oily particles.

Filtration index: 95 series can filter 95% particles, 90 series can filter 90% particles.

For example, N95 refers to the KN series mask, and the filtration index is 95%.

Some models contain activated carbon, which is designed to filter unpleasant odors.

In Beijing, it is better to wear the 95 series, after all, the filtration index is a little higher. In terms of sealing, 8210 can not be folded, so it can be folded, and it is easy to put in a bag or pocket. In addition, it is not easy to breathe when wearing a breathing valve, which will be more comfortable.

Here's a detailed breakdown of 3M masks::

1): N 95 series (less than 10 times, indefinite) 8210 dustproof, 8511 with valve, 8515 electric welding with valve, 8512 with welding valve, 8514 with welding valve, 1860 medical carbon content.

2): N100 series (non-oil as above, ten times more than the standard of use, toxic metal aluminum, cadmium, arsenic and radioactive particulate matter, pharmaceutical industry, etc., above filtration efficiency, 8233 with valve.

3):R 95 series (less than 10 times, 8 hours in oily environment, non-oily until respiratory obstruction, 8247 organic vapor odor and particles containing carbon, 8246 acid gas and particles containing carbon.

4) :p 95 series (less than ten times, oily medium 40 hours, non-oily no until blocked, 8577 organic vapor odor and granules with valve containing carbon, 8576 acid gas and granules with valve containing carbon.

5): 9000 series 9001A 9002A standard, 9003A 9004A small and medium, 9021 9022 durable, 9041A 9042A organic vapor odor particles contain carbon.

6):FFP1 series particle protection (European standard, micron particle size 95 liters, minute environmental test, more than 80% filtration, used in mining, casting, grinding, textile, agriculture and other ordinary, )8200C.

7):FFP2 series particle protection (European standard, more than 94% filtration efficiency, used for ultra-fine industrial dust, suitable for damp heat and long-term wearing) 8822 with valve, 9320 foldable.

8):FFP3 series high toxicity protection (European standard, more than 99% filtration, used for high toxicity, radioactive particles, welding metal fumes, etc., suitable for damp heat and long-term wearing, ) 9332 with valve.

There is no difference, only the level of particulate matter filtration, generally N95 mask filtration efficiency is greater than 95%, N99 efficiency is greater than 99%, N100 efficiency is reached. There is also a difference between oily and non-oily particles, FFP3 masks are currently the highest level of masks, you can refer to Sanhui's SH2550 and SH2300V masks.

Under normal circumstances, as long as you wear an N95 mask, you can already meet the daily needs of life.
