idMASK Sports Soft Silicone Pollution Mask for Running, Jogging, Cycling (Large)

Good:1. great seal no air from sides2. Large filter so no difficulty in breathing3. Filter cleans air effectively4. Easy disassemble procedure can be effectively cleanedCons: 1. Expensive mask with expensive filters2. The silicone seal feels heavy and discomforting on nose area after some time.

It’s a good mask,,made up of soft silicon material, non irritant to skin.. but very expensive.Can able to take breathing, but not fitting to face properly.

While the concept of a changeable filter is certainly good, the weight of this mask makes it unift for daily use. One can only wear it for about an hour before the nose starts paining (as the weight sits right on top of the nose). Useful maybe for athletes who are looking to use it in short bursts, but everyday users should look for a lighter mask

Complete waste of money.. Filter is to be replaced after 1 wk. I feel like bwing cheated.. This is complete money looting policy by the makers.

It is not comfortable

I bought this mask from Nirvanabeing.My review after using for two days.Firstly- the no of filters is only 3 and not 4 as given in the description.Secondly, It is not a very comfortable mask to wear. I got the large size but even that is a tight fit.It intrudes into your field of view which is very uncomfortable. Definitely cannot be worn with glasses/ goggles.The mask sits rather heavy on the nose and is definitely not suitable for extended wear beyond an hour.If you don't buy the shield the filter is exposed.Overall a bad design and definitely not worth the cost.The O2 Curve is a little better option if you really want to go for something like this.
