3M 9330 Aura Fold Flat Unvalved Dust/Mist Respirator, FFP3

Good quality masks, they have the best and most comfortable fit I have ever seen. But they are ridiculously expensive!

While the product and price are great, I was shocked to see that the driver said ''handed to resident''.Especially as a) delivery was not meant to be for at least a week still, but b) I was not even in and came home to the box just sitting in front of my front door for all to see.Amazon have to sort out their staff and their systems as this is not acceptable, they should at least say it was left in the open and resident was not in.

This is one of the only masks without a valve and circular seal that is small enough to fit my face and seal tightly. It's comfortable to wear, even for long periods of time. Two issues I had with it: when first putting it on, the mask is tricky to unfold. There are 3 parts to it and they need to be unfolded while the straps are already in place around the head. This is fiddly to do, especially when touching the face or inside of the mask is supposed to be avoided, and I saw people wearing this type of mask in a wrong way because they were unable to unfold it properly. Also, the chin flap kept slipping inwards and needs to be frequently pulled back into place. I would also like for this mask to be designed so it can be easily reused without contaminating the inside (right now, it's almost impossible to re-fold it without touching inside and outside filter surface together.

+ Good fit if used correctly (I’m a large adult male - reviewers claiming small size haven’t observed instructions).+ FFP3 protection; offers protection for the wearer rather than just from the wearer as per IIR 3-layer surgical-type masks.+ Non-valved design; suitable as a mask to also protect others from the wearer.+ Comfortable for extensive periods of wear.- Single use- Prone to sweat-through- Requires clean shave for effective fit- Can ride up whilst talking- Elastic snags on hair- Elastic retainers poorly designed and fail easily, especially when exposed to low or high temperatures and UV.- Slightly odd smell.

Got a nasty headache after using this mask for the first time. You really need to get it out of its individual packaging and leave for a day before using it. Not sure it is as effective after that though.

Very comfy and feels protective. There have been a few different sellers of these but the ones that I bought were sold and dispatched by Amazon. Some reviews mention a very strong smell when opened. Mine do not have this issue. Other reviews mentioned the straps snapping- again, I haven't had this issue. Yes, the straps are tight- they need to be for this type of mask. But, If you take care putting the mask on and don't over strain the straps, there's no issue. They feel very protective and there was a good use by date. Very happy.

Some people have said it is too small, and it snaps. For me it's a great fit, comfortable, I feel truly protected for the first time! I have a small face, but nothing uncommon, and it feels almost big, so it should accommodate most people (especially with this cool design). The elastics are confusing at first, it seems tight but it expands a lot, and it gives a firm, comfortable hold. I would recommend buying these, especially as this is a real discount, the actual website is quite expensive.EDIT: the foam triggered my latex allergy, but still a great mask for most people

I got these masks for travelling and wore them twice for over 6 hrs without removing. I found them comfortable to use, and it was clear that no air escaped from the sides or around the nose so they also felt very safe.The only downside is that they are more tricky to put on compared to the masks you have loops around your ears. And once on, I found that the top loop kept falling down the back of my head and the rubber material felt uncomfortable on my hair.The internet to the rescue: if you have long hair, put it in a ponytail, just below where you want the top loop to sit. This will help it stay in place, and this is what I did for both my trips.The bands are so tight that after a few hours I found it start to get mildly uncomfortable but nothing compared to how much my ears ache with the other type. So, I will definitely use these if I again find myself in a closed space with little social distancing.Don't wear these before taking photographs - they sit tight on your face and I had marks from the edges on my face for over an hour :D
