Frequently Asked Questions
Helpful answers about face mask types and practical use.
What is the difference between KN95 and N95 masks?
KN95 and N95 refer to different respirator standards. Specifications and approval systems differ, so always check the exact model and its labeling.
How can I choose the right mask size?
Look for a snug, comfortable fit around the nose, cheeks, and chin. Follow the manufacturer’s sizing and fitting instructions.
Do children need different mask sizes?
Children’s faces vary in size. Check sizing carefully and supervise use. Never assume a child-sized design has the same certification or fit as an adult respirator.
Are masks with valves suitable everywhere?
Not always. Some settings restrict exhalation valves because they may not provide the desired source control. Check the rules for your setting.
How should masks be stored?
Store in a clean, dry location and follow packaging and manufacturer guidance on handling and replacement.
