LG Airwasher

Previous post: COVID-19 Masks

While (genuine) N95 (USA) and KN95 (China) masks are still recommended, another good option is KF94, the Korean equivalent to N95 and KN95. Important reasons:

• Readily available
• Designed for extended wear
• Inexpensive

TL;DR: Top recommendation: LG Airwasher KF94 Disposable Face Mask

Reasons:

1. High filtration
2. Good fit and sealing (excellent nose wire, adjustable earloops)
3. Easy breathing and talking
4. Lightweight
5. Comfortable
6. 3D shape (will not collapse onto nose or mouth)
7. Does not fog glasses
8. Inexpensive (reusable, replace weekly)
9. Authentic

Runner Up:

• BOTN KOREA: KF94
