Regarding dustproof performance, it is truly a place like Shigematsu. Resistance to intake and exhaust is also low, and bands do not bother using for a long time. In this period, condensation in the mask occurs and water drips from the lower exhaust port, so we recommend using a genuine water absorbing pad.
One year after purchase, the hook type detachable part of the rubber band cracked. Since one-touch type parts that I used before was able to be diverted, it did not have to be replaced, but there was not even between use, cracks occurred, so I think there was a problem with strength. One-touch type detachable parts were adopted as an inexpensive model, but I wondered why this was a hooking ceremony. The purchase of the mask of Shigematsu is now the fourth one. The first one was an elastomer with a face-contacting part and had durability problems. The next one bought the dressing part was PVC durable but it fell down when sweating. The third one cracked the cover fixing the filter, and this time ... I thought it was Shigematsu as mask ... but I bought it, but I think I will make it as a separate manufacturer next time.
A product manufactured one year ago arrived. It does not affect durability, but it does not feel good. It is hard to use as compared with the thing which can be attached and detached with the one-touch which the rubber band is hook type and used before. Fit feeling is good, there is no gap when moving.
