Welcome to your trusted resource for evidence-based mask information during COVID-19 and beyond. From choosing the right mask type to proper maintenance techniques, this guide offers practical knowledge to keep you and your community safe. Explore our interactive tools, bust common myths, and learn where to find assistance when needed.
Mask Types and Effectiveness
Different types of masks offer varying levels of protection. Learn about each type to make informed decisions.
N95 Respirator
Filters at least 95% of airborne particles when properly fitted. These provide the highest level of protection.
Surgical Mask
Loose-fitting, disposable masks designed to protect against large droplets, splashes, or sprays.
Cloth Mask
Reusable masks made from various fabrics. Effectiveness varies based on material and number of layers.
KN95 Mask
Similar to N95 respirators but manufactured to meet Chinese standards. Filters at least 95% of particles.
Mask Selection Tips
- Choose higher filtration masks (N95, KN95) in high-risk indoor settings
- Surgical masks are good for everyday use in moderate-risk settings
- Cloth masks are suitable for low-risk environments when properly made
- Any mask is better than no mask in reducing transmission
Proper Mask Wearing Guide
Wearing a mask correctly is essential for it to be effective. Follow these steps to ensure proper mask usage.
Steps for Proper Mask Wearing
Wash Your Hands
Always clean your hands with soap and water or hand sanitizer before touching your mask.
Inspect the Mask
Check for tears or holes, and identify the top side (usually with a metal strip).
Position Correctly
Ensure the colored side faces outward (for surgical masks). Place over nose, mouth, and chin.
Adjust Metal Strip
Pinch the metal strip to fit the shape of your nose, ensuring no gaps.
Secure the Fit
Adjust the mask to cover your face with no gaps on the sides.
Common Mistakes to Avoid
Wearing Below the Nose
Your mask must cover both your mouth AND nose to be effective. The nose is a primary entry point for the virus.
Touching the Front
The front of your mask may be contaminated. Only handle by the ear loops or ties.
Gaps on the Sides
Ensure your mask fits snugly against the sides of your face without gaps.
Removing When Speaking
Keep your mask on at all times, especially when speaking, as talking can release more droplets.
Mask Care and Maintenance
Proper care of your mask helps maintain its effectiveness and extends its usable life.
Mask Care by Type
Cloth Masks
- Wash after each use with regular laundry detergent
- Use the warmest appropriate water setting for the cloth
- Dry completely on highest heat setting or air dry in direct sunlight if possible
- Store clean masks in a clean, breathable container (paper bag works well)
Surgical Masks
- Designed for single use – dispose after each use
- If supplies are limited, store in a breathable paper bag and reuse after 72 hours
- Always handle by ear loops only
- Dispose in regular trash after use (tie in plastic bag first)
N95/KN95 Respirators
- Ideally single-use, but can be reused with proper care if supplies are limited
- Keep in breathable container between uses (paper bag)
- Allow at least 72 hours between uses (virus degrades)
- Do NOT clean with soap, alcohol, bleach or other disinfectants
- Replace when visibly soiled, damaged, or difficult to breathe through

Mask Myths and Facts
There are many misconceptions about masks. Here are the facts behind common myths.
MYTH:
Masks reduce oxygen levels and cause CO2 buildup.
FACT:
Masks are designed to be breathable and do not affect oxygen levels.
Medical professionals wear masks for long periods with no health effects. Studies show no significant changes in oxygen or CO2 levels when wearing cloth or surgical masks.
MYTH:
Masks don’t protect against viruses because they’re too small.
FACT:
Masks primarily block respiratory droplets, which carry the virus.
While individual virus particles are very small, they travel in larger respiratory droplets. Masks create a physical barrier that catches these droplets. Multiple studies have confirmed masks reduce transmission.
MYTH:
You don’t need to wear a mask if you’re not sick.
FACT:
People can spread the virus before showing symptoms.
Studies show that a significant portion of people with COVID-19 are asymptomatic or pre-symptomatic, yet can still spread the virus. Wearing a mask helps prevent unknowing transmission.
MYTH:
Once vaccinated, masks are unnecessary.
FACT:
Vaccines reduce risk, but breakthrough infections can occur.
While vaccines dramatically decrease the risk of serious illness, breakthrough infections remain possible. Masks provide an additional layer of protection, especially in high-risk areas or when new variants emerge.
Why Myths Spread
Misinformation about masks often spreads through social media and unreliable sources. Always verify information with reputable health organizations like the CDC, WHO, or your local health department.

Resources for Mask Distribution and COVID-19 Assistance
These organizations provided free masks and other COVID-19 related assistance during the pandemic.
Project N95
A non-profit organization formed during the pandemic to deliver critical PPE to healthcare workers and the public.
Get Us PPE
A volunteer-run organization that helped deliver PPE to healthcare workers and underserved communities.
Masks For All
A grassroots movement that advocated for universal mask wearing and distributed free cloth masks.
COVID-19 Health Literacy Project
Created accessible COVID-19 information in multiple languages, including mask guidance.
Government Resources
Several government programs also provided free masks during the pandemic:
- CDC Mask Distribution Program – The CDC coordinated distribution of millions of free N95 masks through pharmacies and community health centers.
- USPS Free COVID Tests – The U.S. Postal Service delivered free COVID-19 tests to households, complementing mask initiatives.
- State Public Health Departments – Many state health departments coordinated their own mask distribution programs.
Note: Some of these programs may have changed or concluded as pandemic conditions evolved.
