We wear masks hoping to gain extra protection. We understand that pollution in many factory environments is severe, and the protection provided by medical masks is insufficient. We need to wear N95 masks to protect our lung health. However, most N95 masks are too stuffy, too tight, and uncomfortable to wear for long periods while working. Additionally, N95 masks cannot block oily particles. Prolonged exposure in a polluted workplace for eight hours a day can significantly harm our health.

Daily commuting exposes us to exhaust pollution from vehicles, and our work environments might also be severe pollution issues. These exposure problems are familiar and habitual, so we might not be aware of the risks. For example, kitchen oil fumes for chefs and fine machining, cutting oil mist, and grinding particles for engineers are all exposure issues.

The size of kitchen oil fumes ranges from PM0.1 to PM1, and the aerosol particles from lubricant evaporation in factories are also around PM0.1 to PM1. These particles are smaller than PM2.5 and can penetrate not only the alveoli but also the cardiovascular system, causing cardiovascular diseases. Medical masks cannot effectively protect against these pollutants, and neither can the electrostatic filters of medical masks and N95 masks. Many work environments have severe air pollution, but people often overlook this and the long-term health impacts of environmental exposure.

Typical N95 masks have multiple layers of filters, making them bulkier. Due to their thickness, they are less breathable and cannot be worn for extended periods. The

mask uses a special thin-film filter with a microporous structure that allows large-scale air circulation, ensuring smooth breathing. The thin-film material also overcomes the limitation of traditional N95 masks in not filtering oily particles.

The dcmask’s protection level is certified by the EU FFP2 standard, equivalent to the US N95/P95 specifications, filtering both dust particles and oil mist aerosols. Its stylish design and color options also reduce the fear associated with the cup-shaped appearance of N95 masks.

Even better, the dcmask is washable and reusable. One mask can replace 5-7 N95 masks, making it ideal for companies implementing ESG concepts. It addresses environmental plastic reduction, health care for colleagues (from medical examinations to preventive measures), and is cost-competitive in the long run. After washing, its cost is comparable to that of an activated carbon mask while providing N95-level protection.
