This mask is awesome! Super breathable in comparison w/ other N96 masks. Leaves marks on my face.

I have had these for about three weeks. I wear it at work 6-8 hours per day.

They are super breathable compared to other certified N95s (had the ACI Certified N95 before this, great protection but harder to breathe).

Fit is very snug. It leaves mask lines on my face, but I care more about breathability with the same level of protection.

I wear one mask for about one to two weeks at a time. I work in an office, so I don't care much about changing them too often. One of the head straps broke after about two weeks of wear and repeated donning/doffing.

Overall - highly recommend!

These are the best

Comfortable and gentle on the face, secure elastic around the ears and superb nose sealing to prevent leaks. Like putting a gentle balm on one’s face.

Carol Laibstain (Virginia, United States)

Masks are comfortable even when worn for several hours. Online orders are delivered in just a few days.

Important to have good masks now more than ever

As an immunocompromised person I have no other choice but to wear a proper N95. With Blox I know I am receiving safe, legit masks. They are incredibly comfortable and the headstraps are snug but do not pull at my hair. Reliable masks are important to me because our government and general population are done with masking which leaves disabled & immunocompromised people and children under 5 at huge risk. Please make kids ones!

Favorite Mask!

I love these masks because they are snug-fitting, not too tight, very comfortable and they do not touch my lips. I feel safe from exposure when I wear these masks. I also like that they have 2 straps which go around the neck and head instead of pulling on my ears! Excellent design.

Gene (Tennessee, United States)
American Made Mask.

So much more breathable than KN 95 masks. And a much better seal. Over all far more comfortable.

Regina Kiser (Connecticut, United States)
Great masks!

Your masks have a great, snug fit, yet are still so very comfortable. The best part is...they are made in the USA!! <3

Midy (Louisiana, United States)
Like them.

They solve problems.


Multi-layer protection provides
full coverage with an electrostatic filter.

The ‘charged’ meltblown layer provides at least 99% filtration efficiency of 0.1-micron aerosolized saline particles.

Designed with double head straps and a flexible nosepiece for optimal seal and all-day comfort.
Our leading consumer-grade straps provide 0.8 to 1.25lbs of force to maintain an adequate seal.

It’s time for a better
high-filtration respirator.

No more counterfeits
No more annoying readjusting
No more difficulty breathing
No more glasses/goggles fogging up
No more subpar filtering efficiency

Donning Instructions

Step 1

Separate the edges of the respirator to fully open it. Slightly bend the nosepiece to form a curve.

Step 2

Using your index fingers and thumbs, separate both headbands.

Step 3

Continue holding the headbands and cup the respirator under your chin with the nosepiece facing upwards.

Step 4

Pull the headbands over your head and let them rest at the base of your neck, below your ears.

Step 5

Position the top headband to rest at the crown of your head, above your ears.

Step 6

Using both hands, firmly press down to form the nosepiece to the bridge of your nose and below the eyes. Adjust to secure all edges and perform a seal check.

Performing a seal check:

It is necessary to perform a seal check prior to each time of use. To check the respirator seal, cup the respirator with both hands, breathe in forcefully. You should feel pressure inside the respirator. If you feel any air leakage on an inhale or exhale, adjust the nosepiece and headbands until you feel a secure fit with no air leakage. Repeat the seal check again to confirm proper fit. DO NOT enter a contaminated area if a proper seal cannot be obtained.
