Review on GVS SPR551 Elipse Integra Nuisance by Matthew Riley

- Made in the UK - All face contact parts are soft TPE - 2 straps, fully adjustable - Weight 6.944 oz. The difference with an exhalation valve is that it only filters your breaths. Exhalations are not filtered. This makes you safe from others, but others aren't safe from you ;) I have a pretty weird face and masks don't suit me. For example, my cpap mask is a child environment. My eyes and nose are close together, so it's difficult for something that goes over the bridge of my nose to not touch my eyes. The mask is ideal for this. I didn't feel any pressure on my eyeballs. I can wear glasses, but I have to say that my glasses are very small. The earpieces fit well and unlike the half mask version, the nose of the mask doesn't get in the way of my glasses. However, the glasses themselves should be pressed fairly close to my face. No distortion or uncomfortable fit. There is no fog at all. There was no impairment of my vision at all. I have a heart rate monitor, I didn't lose any oxygen in the mask. In fact, I found it easier to breathe with this mask than the half-mask (non-valved) version. I have COPD and have trouble breathing and I wear this with no problem. It doesn't have an oxygen port, but you can easily get one if you have oxygen. Expiry date 1/2026. That's fine too, but vacuum-seal it in mylar until you need it and you'll get significantly longer shelf life. Replacement filters are around $16 at Amz and appear to be on par with other brands. I took a few pictures showing the installation of the replacement filter. That tiny white thing, I thought, means you picked the lock to replace it. It was'nt easy. Turns out there's a big white base inside the mask that's pretty easy to twist to unlock, even with long nails. I might wish it was in the attached info but maybe it will be in a refill pack. Overall I find it quite comfortable to wear and can't take the heavy weight on my face well. The straps were quite soft and I'm really impressed with the nose bridge design. Solid 5 stars for me. This is my perfect mask.
