Well, I wear it more for work, those who say that the filter doesn't protect, etc. are nonsense. Along with the mask, it has several filters that you can put right in front of your mouth-nose, which has a pocket-like feature.
It is very convenient in terms of being held by the head and not the ears, you can tighten or loosen it and the fabric is elastic, it doesn't bother you. The only downside of this mask is its price, that's why I gave it 4 stars instead of 5, which is a bit high, but personally, I liked it and it suited me.

Wasted money on dangerous scams.

The most useless item I have ever purchased! I wonder how they are allowed to circulate it! Supposedly, its purpose is to provide safety due to the product's specifications (weaving characteristics, geometry and design, etc).
The most basic flaw: the fabric fully adheres to the nostrils and mouth, resulting in moisture from the first moment.

It is impressive how the sellers promote it... It is obvious that anyone who buys this mask, at the outrageously high price of 19-20 euros, does so to have a protective measure against viruses, bacteria, pollutants... which is also somewhat fashionable.
The company describes it very cleverly, avoiding taking responsibility for the suitability of the product:
Features - CoolNet fabric mask with a 3-layer filter system with 98% bacterial filtration efficiency. The package includes five replacement filters that meet surgical mask standards. ...
Warnings - The mask does not protect users or others from pathogens...!

Between serious and funny, the only way to make the mask functional is to use it with a silicone accessory that fits from the inside and leaves the necessary distance from the mouth and nose (available in some pharmacies)... unless someone wants it for Halloween!

Unacceptable.
It goes into the mouth when you speak.
The straps press on the ears.
It presses on the nose too much!
The size is not suitable for a large face, in a striking way, nor for a small face! and it creates different problems for everyone.
For me, it was small, so it comes out of the nose in the first word, it didn't have enough strap length, it presses on the nose.
For my girlfriend, it was big, so it wrinkles on the chin. It requires a lot of tightening to stay in place, so it still presses on the nose.
And it bothers both of us in speech (goes into the mouth).

+It is very beautiful

+ It does not hang from the ears and therefore does not cause fatigue when used.
+ It hugs the face and does not have gaps like other masks.
+ Lightweight.
+ Easily adjustable for any type of head.

- Both the mask and the recommended filters are expensive and need to be changed every 24 hours.
- Glasses fog up no matter where you put them.
- It starts to feel a bit uncomfortable on the nose after 1-2 hours

The mask has a very good fit on the face and can be comfortably worn by a six-year-old child without discomfort or complaints about anything bothering them or not being able to breathe. It is very comfortable and highly recommended. The filters are very thin and we change one per day. The 30 filters cost 15 euros. For the comfort and perfect fit, it is worth its money.

First of all, without an inserted filter, the mask is essentially useless. The fabric is very thin, yes it is lightweight, but it feels fake. I'm afraid I will tear it every time I open it to put it on. Seriously guys, don't buy it, it's not worth it.
Edit: The filter keeps crumpling up and tends to come out, so you have a white thing sticking out, and you have to constantly fix it if you don't want it to show.
