High-quality masks. The air in the place where I work is not good. I have tried several other masks and I always cough. Since wearing this mask, I don’t cough anymore.
Jackie Wang –
Thanks for your feedback ,yes, the built -in nano filter film helps the mask to reach the 95% filtration efficiency , so it is a mask have real function.

These are the best masks we have used. My daughters were provided with them at their school, and after using them, the youngest brought me the package and asked me to order more, since they were comfortable and easy to breathe in. I ordered extras for them and some for the rest of the family. We haven’t been using any of our other masks since getting these, since they are noticeably better.

This mask is the best I’ve tried so far in terms of not fogging up my glasses. Not perfect, but better than all the others I’ve tried – the metal nose strip is substantial.

Great masks. Got a few more for my son after VSB gave them out. Fits great and he claims they are the most comfortable masks we’ve got for him over last 12 months. Easy local pickup option too. Fast and convenient.

Elizabeth G. –
I bought 2 mediums and 2 large for myself, my husband and 2 teenage boys. Both sizes work for all of us. They are very comfortable and seal very well. The fabric sucks in when we inhale, and I can wear the with my glasses without fogging up. Overall I think these are the best masks I have purchased yet. They are more comfortable and better fitting than the disposable kn95s I purchased from Costco

These masks fit really well and having the adjustable straps and nose wire is great when I’m wearing glasses. The shipping was fast and the masks were just as pictured on the website 🙂
Bob C. –
Masks are extremely well made. Best I’ve ever tried. Coverage is amazing. Fits so well. So many options for adjusting. Fits so well that it doesn’t fog up my glasses
David T. –
Best fitting mask yet – and I have twenty in my drawer! No joke. Good fit around nose which is the most important thing (no foggy glasses anymore!!!). I went XL because I have a sizeable beard and it covers that too instead of having the beard bush out the bottom… Keeps all the air contained. Nice feeling fabric. Love that I can wash it. XL was the right choice and great for people with glasses, larger faces, beards etc. Seriously how can I get so excited about a mask?!?
Troy –
It fits great no issues but worried about the tab to adjust it
Simon –
These masks are great! Having bought many, many masks this past year, these are the best so far for comfort, value and protection. I love that they can be washed too, making them more environmental.
I picked up my masks to get them faster and it was an easy process. Will buy more of these as needed.

Because of the nose wire, the mask fits very well and the glasses don’t fog up. Comfy and breathable.
Mickael M. –
They fit reasonably well, are mostly comfortable, easily adjustable, and look great. The N95 rating is very helpful. The only downside is talking seems to pull it down on my face somewhat.
Jackie Wang –
hi Mike, thanks for your feedback ,if you found talking will pull the mask down , then we would like to suggest you choose one more size bigger to avoid this problem . thanks!

Awesome mask. Seals well and no need for a filter. My eye-to-chin measurement is 4.5 inches and so I ordered size large. I think medium would fit better so next time I’ll order that.

I haven’t had a chance to use the mask yet, but delivery was terrible! I PAID to PICK UP my mask since Purolator only comes once and I was on a call with a client and couldn’t just drop off to go down and pick up the envelope. Should use Canada Post for local deliveries. An expensive mask and I hope it is worth it. I don’t think I will buy again.
Jackie Wang –
hi Nadine, sorry about the delivery issue , in fact we pay more to Purolator than Canada post ,we expect a much better service ; already complain to Purolator and hope they can improve their service ;

Very comfortable and fits just right. The adjustability is a nice feature. I feel much safer with this mask then a plain fabric one, and it’s nicer than the standard blue mask that are everywhere.

Comfortable to wear.

This rating is not on the mask itself, since it still hasn’t been delivered and at this point probably never will – the estimated delivery date just keeps moving out and out. My recommendation to 3SMask is to pick a more reliable courier service than ICS if you are going to be soliciting customer feedback on your product.
Jackie Wang –
HI Neil, sorry about the delivery problems ,we talked to the logistic company and they said the parcel will be delivery today, we will change to purolator for future shipment ; at the same time we will refund the shipping fee to you as compensation ;
Jody W. –
The masks were ordered and delivered very quickly. It only took 3 days to get across the country. I had ordered 2 black (M and L). I was a bit disappointed that I was given a black and grey, but the masks do work as intended and the fit is great. My glasses do not get steamed up when mask put on correctly.
Jackie Wang –
hi Jody, sorry about this mistake, I have seen your second order coming in ,we will give you one Black MFF-5 free and ship them together with your second order, thanks again for your trust and support !

My husband’s favorite mask by far! He finds it most breathable and the extra strap helps with his hat and glasses combo.

While they don’t eliminate glasses fogging these are the best I have used in minimizing it. Really like the adjustable strap options

I heard about the kn 95 filter and liked it was reusable so I got this as large for myself and x-large for my son. Really like the shape and my son like the nose clip and said this mask did not fog up his glasses. I received compliments how nice it looked on me. I found it was easy to breathe and talk while wearing this mask.
I would probably buy more if it came in pink or lilac and also suggest the inside lining not be white as my makeup gets on it. I’m going to get one for my friend as she has smaller features and the adjustable straps will be good for her.

These masks are BY FAR the best on the market. They are comfortable, breathable, seal around the nose/face well and if the reports are true about being similar to an N95, then these should be the reusable ones that everyone uses. Love the little Canadian flag on the side. Absolutely love them. Hope you keep making them as we see ourselves wearing masks indefinitely in crowded areas and transit.

Great fit, good protection, well made.

Can’t imagine my teaching day without these! I own many masks but since I started using these last March, these masks are all I wear. They don’t fog up my glasses and I have no issues wearing them for eight hours.

Bought several masks for myself and my family. They are comfortable and I am happy to be able to have a higher level of protection due to the n95 equivalent filtration. The only small issue I note is that the metal nose bridge on several of the masks has broken after a few months of use. The mask is still wearable and fits well, but the broken nose piece does make it slightly less comfortable. I would easily recommend this product and have just put in an order for several more.

The wire on the nose bridge breaks quite easily, other than that, the mask is very breathable, fits well, comfortable

This is a comfortable, well fitting mask. The mask seals well preventing fogging on glasses and eye irritation do to airflow directed towards the eyes as I have experienced with other masks. The back strap is a nice addition both to ensure a sealed fit without causing ear discomfort. I would highly recommend these masks!

I was amazed at the speed of delivery – less than 24 hours. Beyond that it met all my expectations for comfort and wearability. I’m a conductor and no other mask stayed on my face. I spent more time adjusting my old ones than conducting. Not only did this stay put, I could easily be heard as I spoke throughout the rehearsal. You have greatly eased my anxiety and my frustration. I thank you and the musicians I conduct thank you double that.
