***交換用フィルターのみ。FR1レスピレーターマスクは別売りでこちらから購入できます
FR1レスピレーターマスク用の交換可能な活性炭フィルター10枚入りです。
これらのフィルターはPM2.5対応です。PM2.5規格は、2.5ミクロンまでの粒子状物質（PM）をブロックし、煙やスモッグを含み、ウイルス、細菌、ガスも吸収します。毎日使用した場合、フィルターは最長1週間効果が持続します。
Opened the box and immediately noticed the carbon layer is thicker than the last pack I bought, which makes me feel better about wearing the mask on smoky days. Swapped one in last night, and I’ve already gone through two of them while painting—no chemical smell getting through at all.
Ten filters for the price of a coffee run, and they click into the mask without any fuss. I've been swapping them out weekly during wildfire season and the seal still feels tight, no gaps around the edges.
The carbon layer actually holds up well over a couple of weeks of daily wear, which surprised me for the price. Ten filters in one pack means I’ve got spares stashed in my car and workshop without worrying about running out.
