Review on 🌪️ Optrel Efficiency Powered Purifying Respirator: Ultimate Protection, Unmatched Performance! by Chris Dildine

Ok here is a more detailed breakdown of this product with no 'professional declaration' - the mask itself is mostly comfortable to wear. It sits well on my head and I had to fiddle a bit to get it to fit perfectly. but it came. Take a few minutes to set it up and wear it for 15-20 minutes to make sure you use it comfortably before you need to use it. So you don't have to mess around with it in an unstable environment. - If you have a beard there is enough room in the mask to fit it in the mask, there is a pouch-like area just under the chin for your beard to fit in there. However, if you have a short beard and sensitive skin, it can cause irritation. IF you have stubble, don't do it. The tape likes to irritate the daylight from your lower jaw. If you don't like facial hair, people with sensitive skin will find this tape annoying. But it's better to have a slight jaw irritation than to breathe in Covid or a room full of sawdust or whatever you're trying to filter. - The weight of the mask. I personally have a neck fusion and don't find it uncomfortable to wear. 9 hours straight. It is made of lightweight plastic and is durable. I often hit my head because I'm not used to having such a large impact radius on my head, so durability has been extensively tested. The battery lasts all day on the MED setting, I don't need it on high for a whole day so can't say it lasts all day. (I'll update this as I test high settings throughout the day.) - The hose touched the top of my head at first, but after a few seconds of adjusting its position, that's fixed. It's also very flexible and not ribbed enough to restrict movement so you hardly notice it. It's also soft so it won't irritate if it hits you on the back. - The strap is too long, but I have found that if you thread it through the loop provided as usual, you can reattach it under the same loop. . You can loop the belt up to 3 times, think of the resulting shape as "unu", this will greatly reduce the length of belt protrusion. With the belt bent on each side, it will not slip or dangle. The combined weight of the battery/filter pack can be burdensome for those who carry it too high on their body, such as above the waist on the lower body. return. I wear mine below the waist of my pants. It doesn't touch my back and it takes a little getting used to, but it solves all back strain issues. However, this does nothing to sit in the chair. But that goes for all these devices, they weren't originally designed for that. Simply detach and place where the tube reaches, for example on the floor. Noise Level: Pretty loud for an office. If you're working somewhere with a decent level of ambient noise, it will blend into the background fairly easily. The carrying case provided fits the mask and filter unit snugly, however this requires you to remove the tubing from both. the included clip is of little help. I've found that if I walk too fast the mask seems to pop out of the clip, either poorly designed or not intended as a walking storage clip. Velcro strips secure it. Just glue the hook strip going through the gap and the loop strip on the side. and it keeps it securely in place so you can walk around with your seat belt securely fastened. If you stick it any other way, you'll probably rub it with your hand a lot and get into your pockets, irritating the skin, that's my 2 cents. - My final comment for those who have been thinking about the inevitable bodily function. No, it doesn't completely filter out your own gases when you release them. Personally, I was surprised by this, BUT it's not surprising that the gas from the filter appears to seep into your mask. However, I could not detect any similar odors in toilets and other smelly places where odors are common. I suspect it was due to the concentration and distance to the entrance and I didn't test this to confirm. If you pass gases frequently, wear a filter or something else to avoid hurting your face. (should have said) I hope you found this helpful.
