FAQ
1. What’s the difference between the Dacian FFP2 respirator mask and a regular medical mask?
The Dacian FFP2 respirator mask offers N95/P95-level protection, which is significantly higher than that of standard medical masks. Anything a medical mask can protect against, the Dacian FFP2 mask can handle—and more.
Most medical masks use electrostatic melt-blown material, which is effective against particles larger than bacteria (typically around PM3). However, the real threat to human health lies in fine particulate matter smaller than 2.5 microns (PM2.5). Electrostatic materials lose filtration efficiency over time due to moisture from breathing, and they are ineffective against oily particles like cooking fumes or vehicle exhaust. Additionally, these materials cannot be washed or disinfected with alcohol.
In contrast, the Dacian FFP2 respirator mask offers 99% filtration efficiency against particles as small as PM0.075. Its nanofilm filter protects against both ultrafine particles and oily aerosols, making it suitable for everyday air pollution (PM2.5), occupational exposure, and health protection against germs. The Dacian mask also combines high breathability with superior filtration, and it’s washable and reusable—making it a comprehensive, all-in-one protective mask.
2. Has the Dacian 3D High Protection Mask been certified under CNS 15980, EU FFP2, or other standards?
Yes, the Dacian 3D High Protection Mask has passed Taiwan’s CNS 15980 national standard for anti-smog (PM2.5) masks, meeting all eight A-level test criteria under Method A.
It is also certified under the EU FFP2 standard, which is equivalent to or exceeds the N95/P95 level in the U.S., offering protection against both fine particles and oily aerosols.
In addition, the Dacian 3D High Protection Mask meets several international standards, including:
Taiwan’s TN95
China’s GB/T 32610 A-level and KN95
Korea’s KF94
Other Dacian masks also meet relevant standards:
The Dacian Fitted PM2.5 Filters Mask is certified under Taiwan's TN95 testing standard.
The Dacian Flat Face Mask is certified under China’s KN95 standard.
Furthermore, the Dacian High Protection Mask has undergone a variety of laboratory tests in the U.S., Japan, China, and at National Chiao Tung University in Taiwan.

3. What’s the difference between the Dacian High Protection Mask and an N95 mask?
Globally, respirators are categorized based on the type of particles they filter:
“N” for non-oil-based particles
“R” and “P” for oil-resistant or oil-proof particles, with “P” being the highest grade
The “N” in N95 stands for “non-oil resistant”, meaning it's only effective against particles that do not contain oil.
However, in today’s environment, we're constantly exposed to oil-based pollutants—from vehicle exhaust and industrial emissions to kitchen fumes and BBQ smoke.
The Dacian High Protection Mask goes beyond standard N95 protection. It is certified to the P95 level, meaning it filters out both non-oil and oil-based particles with over 95% efficiency. It meets multiple international standards for oil particle protection and has been tested by National Chiao Tung University’s Department of Environmental Engineering, confirming its ability to filter out heavy metal particles in the atmosphere.
The Dacian High Protection Mask is ideal for occupational safety, kitchen use, air pollution (PM2.5), and flu/allergy protection. It is also washable, disinfectable, and reusable, making it a practical and durable option for everyday use.
4. Is there a difference between the Occupational High Protection Mask series and standard basic masks?
Whether it's our 3D-fit, slim-fit, or Occupational High Protection series, all Dacian masks use the same high-grade nanofilm filter. This means every mask in our lineup provides effective protection against air pollution, oily particles, fine dust, and germs—and can be washed or disinfected with alcohol for reuse.
The Occupational High Protection series was created to promote the idea of "respiratory protection in the workplace."
Many people work over 8 hours a day in high-pollution environments (often during severe air quality alerts), yet most aren't aware of the long-term health risks from chronic exposure. Sadly, some only discover health issues years after retiring from decades of hard work.
To help raise awareness, we use color-coded masks for different industries and provide detailed information in our brochures about the specific pollutants and risks each industry may face. This helps workers better understand the hazards in their environment and take proactive steps to protect their health.
Since all masks in the High Protection series use the same filtration material, they offer comprehensive protection—whether against fumes, aerosols, fine particles, or PM2.5.
If you're already thinking about your respiratory health, you can simply choose the color that fits your profession or personal style.
5. What’s the difference between the 3D Protective Mask, Fitted Facemask, and Flat Facemask?
The 3D Protective Mask, Fitted Facemask, and Flat Facemask all use the same high-grade Dacian filter material, offering the same level of protection. The main differences lie in the fit, comfort, appearance, and the fabric used on the outer layer.
The 3D Protective Mask features a specially designed cut and curved shape that creates a spacious breathing chamber, making it more breathable and offering a better facial seal compared to the flat design.
The Fitted Facemask is an upgraded version of the Flat Facemask. It’s a slimmer, more contoured design that improves both the seal and comfort, addressing some of the limitations of standard flat masks.
The Flat Facemask is the basic model, offering solid protection with a simpler, traditional look and fit.

7. Can the Dacian High Protection Mask be used to protect against secondhand smoke? Does it block the smell of chemical solvents?
Yes, the Dacian High Protection Mask is effective against secondhand smoke, but it’s important to understand how it works.
For example, secondhand smoke contains smoke odor, tar, and nicotine, which are made up of both gases and aerosols.
Odors are carried by gas molecules, which can pass through any breathable mask. So you may still notice a faint smell, since our mask is designed to allow airflow.
However, the harmful components—such as tar and nicotine—exist as aerosol particles. These are the real health threats, and the Dacian High Protection Mask is designed to block more than 95% of these oil-based aerosol particles.
In short, while you might still notice a light smell, the mask effectively blocks the particles that are dangerous to your health. If you’re still noticing strong odors, it’s usually a sign that the mask isn’t being worn correctly. Be sure to check the fit and seal, especially around the nose and chin.
So yes, the mask is suitable for secondhand smoke protection, as well as for filtering aerosolized chemicals and fumes—just make sure it’s worn properly for the best protection.
8. How do I clean the mask, and how many times can I reuse it?
Cleaning the mask depends on whether you're targeting microorganisms (germs) or fine particles (PM2.5) and oily pollutants.
For disinfecting germs and bacteria:
You can spray the inside and outside of the mask with 75% or 95% alcohol, hypochlorous acid water, or any disinfectant you trust.
Once the disinfectant fully evaporates and dries, the mask is ready to use again.
For removing fine particles and oily residue:
We recommend:
Soaking the mask in diluted mild detergent, then gently press-cleaning it by hand
Or rinsing it under clean running water for 30–60 seconds, followed by air-drying
If you have oily skin, using warm water can help better remove skin oils
Suggested reuse time (varies by mask type):
3D Protective Mask: Replace after 5–7 days
Fitted (Slim) Mask: Replace after 3–4 days
Flat Mask: Replace after 2–3 days
If the filter membrane becomes damaged, or the mask starts to feel stuffy or hard to breathe through, replace it immediately.
When cleaning, avoid rubbing or scrubbing, as it may damage the shape and structure of the mask.
For a detailed cleaning demonstration, watch: https://youtu.be/9ZiYoNQCKPY
According to TTRI (Taiwan Textile Research Institute) testing, even after 5 alcohol cleanings or 5 water washes, the Dacian High Protection Mask maintains a 99% filtration efficiency.
9. Why does my mask feel stuffy after cleaning?
If your mask feels stuffy or harder to breathe through after washing, it's likely because the tiny air-exchange pores in the filter have become clogged, reducing breathability. As a result, you may notice the mask moving in and out with each breath.
This usually happens when residue from the cleaning agent—such as foaming agents, thickeners, or other additives—isn’t fully rinsed off. The nanofilm in the mask may treat these leftover substances as contaminants, causing them to block the filter surface and restrict airflow.
To prevent this:
Always dilute the detergent before use
- Or lather the detergent in your hands first, then gently clean the mask with the foam
- Make sure to rinse thoroughly with clean water until no residue remains
- This will help keep the mask breathable and comfortable after cleaning.
10. What types of jobs require the Dacian High Protection Mask?
If your work environment involves dust, oil mist, smoke, sparks, or chemical odors, then the Dacian High Protection Mask is highly recommended.
Workplace safety isn’t just about immediate hazards—long-term exposure to air pollutants can lead to serious lung and cardiovascular issues. In fact, the Ministry of Labor has long promoted awareness around occupational cancer, emphasizing the importance of protection from airborne risks on the job.
Some examples include:
- Kitchen work: The cooking fumes you inhale are the same as those pulled into the exhaust hood—rich in oily particles harmful to your lungs.
- Precision machining: Cutting oil mist doesn’t just settle on the floor—it lingers in the air, where workers can unknowingly breathe it in.
- Welding: Welding generates not only sparks, but also toxic smoke containing heavy metals and hazardous substances. Long-term exposure can cause serious health problems.
- Carbon fiber / powder metallurgy: Grinding and casting release fine particles and microfibers that can embed in your skin or enter your lungs and cause lasting damage.
- Nail and hair salons: Dust from nail filing, acrylic powders, solvent vapors, and hair dye aerosols all get into the air—and into your lungs.
If your job regularly exposes you to any of these risks, the Dacian High Protection Mask offers the comprehensive protection you need.
11. What information does the QR code on the mask box provide?
The QR code on the seal of the outer packaging links to the production record for that specific box of masks.
Each batch of Dacian filter material is tested by a third-party inspection agency, and only batches that pass all standards are used for mask production. Every box of Dacian High Protection Masks has a unique serial number, and by scanning the QR code, you can easily access:
- The filter test date
- The filter test report
- The mask production date
- The box’s individual serial number
This ensures traceability and transparency for every mask you wear.
12. I need a mask for kitchen oil fumes or riding a scooter—are activated carbon masks effective? What kind of mask should I use for oil-based particles?
According to research from Taiwan’s Ministry of Labor, activated carbon masks are not effective at filtering organic solvents.
(Watch the video at 3:19 mark)
You might notice that some activated carbon masks have a strong smell of their own—often stronger than the odors they’re supposed to block. This is a sign that they’re not truly absorbing external pollutants, and they’re also ineffective against oil-based aerosol particles like kitchen fumes or vehicle exhaust. That makes them unsuitable for use as oil-fume protection masks.
Activated carbon works by adsorbing pollutants from the air, but most carbon masks on the market aren’t vacuum-sealed, so there’s no way to know if the carbon is already saturated before you even open the package.
Kitchen fumes and vehicle exhaust contain aerosol particles, not just gases—and ordinary activated carbon masks can’t effectively filter these aerosols.
The Dacian High Protection Mask uses a nanofilm filter that blocks aerosol particles, including those found in oil fumes and exhaust, making it a suitable choice for this kind of protection.
You can choose either the Kitchen Oil Fume model or the Chemical Aerosol model, both of which offer comprehensive protection in oily or polluted environments.
