Review on 💧 Enhanced Filtration: Polypropylene Electrostatic Non Woven for Maximum Efficiency by Draven Invert

I thought it was washable but the follow up email said it wasn't washable. I use it on the back of a fan to clean the air in the room. The back of my fan is round and domed so I figured this would work better than fitting a replacement air conditioner filter. I cut and sewed on a sewing machine a round piece for the face and a long rectangular piece for the side. As soon as I put it on, I realized that I could just throw the fabric over it without sewing anything because it doesn't come off when the fan is on. Or simply tie to the sides of the stand with a divided excess on the fabric sides. It's hard to tell which side is out. I thought the cotton looking side should face unfiltered air, but then I read for a letter that said the micro-embossed side should face unfiltered air. So I did mine backwards and then had to flip it. There's enough maintenance to make a few of these. I have a traditional HEPA filter in my home air conditioner, but the weather where I live is so good most of the year that I almost never turn on the air conditioner and open the windows frequently. The problem is, the outside air isn't that nice here,
