Bloc N95

I originally purchased the top line cloth 3 layer masks pre vaccine and post vaccine. Giving credit to utube channel Sandy at DIY health advice throughout 2020 to current showcasing first the high quality cloth masks when N95s were not available to her transition to only NIOSH approved N95 masks. This gave us followers first hand information along with her modeling all the masks and how they fit. I found this mask through her channel among a couple other manufacturers and this is my preference. This N95 is my favorite duckbill. I only use duckbill. I won’t name competition. Your N 95 rates above the competition with its secure seal across my face. No safety glasses fogging and easier breath ability without compromising quality effective coverage. I am a retired radiation health and safety officer who has donned full face masks with with filters. I have fit tested my team and understand the importance of a complete seal. I treated this virus like I treated radiation. You can protect yourself from both with the proper protective equipment, time distance and shielding.

Excellent masks

These blox N95s are the best masks I’ve tried and I’ve tried many! These masks actually fit with a great seal and still room to breathe.

Answer to a prayer.

Perfect for me. Having had radical surgery on one ear, N95 'around-the-ear' masks were out of the question. Blox N95 masks were just what I needed, one band around the neck, there other over the top of my head, Perfect, tight fit, breathable, and sturdy.

Love these masks they are so comfortable in

Rene (North Carolina, United States)
Very impressed with this N95 mask

Purchased these to be safer in crowded places. Excellent quality! I appreciated the instructions on how to put them on and make sure that you have a snug seal around the edges. They are much more comfortable than a "surgical" mask in that they wrap around the head and not the ears. Additionally, the mask does not rub again the mouth or skin around it so it makes breathing much easier and you can wear lipstick, or balm and not have it smear all over your face. Since you can put it in a paper bag and close it up for 3 days then reuse it, it is more economical than it appears. I feel more comfortable in close spaces wearing this and knowing I can be around people.

Erin Schick (New York, United States)
Sufficient and comfortable

These masks fit much better on me than other N95 styles I have tried, and the seal stays tight even with opening my mouth as wide as I can, exercise, and humidity. They are reasonably priced compared to similar products and will be my go-to for as long as masking is necessary. The only way I can think to improve them would be a bit of padding over the bridge of the nose.

Patricia Sutton (Massachusetts, United States)
Most comfortable, well fitting mask

This is the best mask I've found--fits properly and very comfortable. The only downside is that the elastic is a too tight to start and needs to be stretched out a little bit before use.

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.
