Review on （2 Pack）H13 Suitable Electrical Respir∂Tor Compatible by Demetrius Patsion

Works. Bought this for my wife who is on a dialysis chair for 3-4 hours every other day. Where she sits, smoke seeps from multiple sources. She practically cleared her throat. The AirPro mask saved her a lot. Now she can sleep peacefully whenever she wants during treatment. Many people get dizzy when wearing a mask, they almost constantly breathe their own breath (Co2). The positive air pressure she breathes through the HEPA filter mitigates this; it is actually a constant flow of good air (O2).
