I have been wearing masks from this company for a few years now. I only buy the masks with a valve because they are easier to breath through and cooler to wear and I always use the headstraps and never the ear loops, which are too thick to be comfortable. The nose foam sometimes comes off when the mask is being washed but I have found a cheaper alternative nose foam which works just as well and helps seal the top of the mask. The mask is comfortable to wear for a few hours at a time. I like that it has a carbon filter which definitely reduces the smell of car fumes (I've tried walking in a busy area with and without the mask). My asthma in winter isn't as bad because the mask heats up the air around my face and for the third year running I haven't had much hayfever and haven't had to dose myself on antihistamines all summer. I have a few of these navy blue masks and they are a good colour for matching with most of my outfits. I will continue to buy these masks in future. They are cheaper than disposable and give a better fit if you get the right size and wear it properly. The thick ear loops are a mystery though. I can't see how you can get a good seal and have a comfortable mask wearing the ear loops and not using the head strap. A redesign with 2 straps that go around the back of the head would be awesome but I realise that costs money and the mask works well enough for me to stay a customer. I've even bought some for family members in the past.
