P2 masks and N95 masks are very similar in terms of performance and protection, but they differ slightly in terms of standards and certification:

• P2 masks: Certified under the Australian/New Zealand Standard AS/NZS 1716. They are designed to filter out at least 94% of airborne particles down to 0.3 microns in size. AMD P2 face masks, however, exceed this standard, offering a filtration efficiency of more than 95%, providing the same level of protection as an N95 mask.

• N95 masks: Certified under the US NIOSH (National Institute for Occupational Safety and Health) standard. They must filter at least 95% of airborne particles of the same size.

Nano-filter technology in face masks offers advanced protection and superior performance compared to standard masks that use meltblown filters. Here are the key benefits:

1. Higher filtration efficiency:

Nano-fibre filters provide superior filtration efficiency, capturing particles as small as 0.3 microns with enhanced precision. For example, AMD P2 masks with nano-filters exceed the filtration standards of traditional P2 masks, offering a performance comparable to N95 masks.

2. Better breathability:

Nano-fibre filters are thinner and less dense than meltblown filters, allowing for improved airflow. This makes masks with nano-filters more comfortable to wear for extended periods, reducing the strain often associated with traditional masks.

3. Moisture resistance:

Standard P2 masks with meltblown filters rely on electrostatic charge to trap particles. This charge diminishes when the filter is exposed to moisture, reducing its effectiveness. In contrast, nano-fibre filters maintain their filtration performance even after exposure to humidity or moisture, making them more reliable in real-world conditions.

4. Lightweight and comfortable:

Nano-filter masks are lighter and less bulky than their meltblown counterparts. This ensures a snug yet comfortable fit, making them ideal for long wear in workplaces, healthcare settings, or personal use.

5. Longer lifespan:

Because nano-fibre filters retain their functionality under challenging conditions, masks like AMD P2 face masks can last longer without degradation, providing consistent protection over extended periods.

Key difference between meltblown and nano-fibre filters:

• Meltblown filters: Use static electricity to trap particles, which can degrade when exposed to moisture or over time. Masks with meltblown filters may become less effective after several hours of use.
• Nano-fibre filters: Physically trap particles using a fine mesh of fibres, maintaining high filtration efficiency even in humid or moist environments. This makes them more durable and reliable in a wider range of conditions.
