One kind having the feeder for sensing and showing aerosol concentration, can detect air suspension particle concentration comprising a blowing unit, the gas transmission unit of a connection what blowing unit, one and export the particle detector of concentration signal, a Resetting Switching that the operation result of the control unit can be zeroed to the control unit for being replaced and cleaned the time of one strainer of decision, the display unit and one to show the strainer efficiency according to the concentration signal. Thereby, it can make the feeder that there is the air demand of preferable air feed quality and abundance, and look after sufferer most preferably.一種具有感測及顯示懸浮粒子濃度之供氣裝置，包含一送風單元、一連結於該送風單元的輸氣單元、一可偵測空氣懸浮粒子濃度並輸出濃度訊號之微粒偵測器、一依該濃度訊號用以決策一濾網之更換清洗時間的控制單元、一用以顯示該濾網效能之顯示單元及一可將該控制單元之運算結果歸零的重置開關。藉此，可使該供氣裝置具有較佳供氣品質與充足之供氣量，且使病患得到最佳照護。
