N95 / KN95 Masks: Your Questions Answered

As the COVID pandemic continues and personal protective equipment start running out, there’s understandable confusion as to what facial masks to use. What is the difference between N95 vs. KN95? Is it safe to use KN95? What is a standard/industrial dust mask vs. surgical/medical grade? What is FPP1, FPP2, FPP3?

We at  have compiled this list of resources to help everyone make well-informed choices on what masks to buy, use, or donate.

The bottom line is, with richer countries cornering the N95 market and driving factory prices up, exponential increase in shipping costs, and China tightening requirement for PPE export, what alternatives are accessible, affordable and safe?


1. The US FDA approves use of KN95 due to shortage of N95.

2. N95, KN95 and FPP2 are all similar. There are different names for different countries of origin.

3. Standard N95 masks—classified as dust masks for industrial use—are allowed by CDC for use in health care settings.

“Most HCP caring for confirmed or suspected COVID-19 patients should not need to use surgical N95 respirators and can use standard N95 respirators. If a surgical N95 is not available for use in operative or procedural settings, then an unvalved N95 respirator may be used with a faceshield to help block high velocity streams of blood and body fluids.”

4. KN95 masks are also classified as standard and medical/surgical. Standard KN95, as the equivalent of standard N95, can also be used in healthcare settings based on parameters given in #3.

Surgical KN95s have the following codes:

– GB 19083-2010 “Technical Requirements for Medical Protective Masks”

– YY 0469-2011 “Medical Surgical Masks”

– YY / T 0969-2013 “Disposable Medical Masks”

Standard KN95s have these codes:

– GB 2626-2006 “Respiratory protective equipment self-priming filter anti-particulate respirator”

– GB / T 32610-2016 “Technical Specifications for Daily Protective Masks”

5. European standard classifies protective face masks/respirators as EN 149:2001+A1:2009 and has 3 classifications:

– FPP1: filters at least 80 % of the particles measuring up to 0.6 μm

– FPP2: filters 94 % of the particles measuring up to 0.6 μm

– FPP3: filter 99% of all particles measuring up to 0.6 μm (when working with oncogenic or radioactive substances or pathogens such as viruses, bacteria and fungal spores FFP3-class respirator masks are recommended)

6. 3M manufactures BOTH KN95 and N95 masks. 3M is also one the most counterfeited.

IAHV Philippines Launches its First Peace Building Activity

From June 19 to June 21, 2019, The IAHV Philippines team, in partnership with the Armed Forces of the Philipines (AFP), visited three areas in Lanao del Sur, Mindanao. We conducted peacebuilding introductory workshops among the Moro Islamic Liberation Front, an insurgent group, former Maute-ISIS returnees and local government units.

It was the first time ever that these groups were together. Although the tension and uncertainty was high in the beginning, we are happy to report that it was a resounding success! The sessions were productive, the participants were involved, and there was an overwhelming feeling of hope over the three days.

Imagine what else we can do!

We’d like to share some testimonies from the participants:

“(The) MILF brothers are the happiest. They are not crying outwardly, but inside, they are crying with joy because of this camaraderie. Our troops really want this to happen again especially since our families need it” –Sommy Mangandog Panda “Commander Bangladesh”, 101st Command, Northeasatern Mindanao Front, Moro Islamic Liberation Front (MILF)

“Before we couldn’t sleep. We feared that the military would run after us. We fear our fellow ISIS co-fighters because they want to kill us. We felt (because of the activities) that this is how to release anger in your life. It was peaceful. It can help us, our children and our families. Because sometimes we don’t know how to release and control our anger.” -“Randy”, Former Dawla Islamiah (Maute ISIS)

“We are very happy that we saw the cooperation between the troops of MILF and the Philippine Government. I am so happy! I have been dreaming of this for a long time, wherein the struggles of both sides will result in achieving true peace for all the youth and citizens of the entire Mindanao.” -Ahmad Sabilullah Lintuan, 101st Command, Moro Islamic Liberation Front (MILF)

“I…quote from one of the commanders how he wished that his comrades were alive to see this day, to see that they have finally won peace together with the soldiers and the community. And everything they fought for was not in vain.” -Capt. Ron Villarosa, Jr. 103rd Infantry, 1st Infantry Division, Philippine Army
