Review on MZY LLC 12 Pack Hepa Filter Replacement Filters for iRobot Roomba 800 900 series - Models: 860, 870, 871, 880, 960, 980 - Robotic Vacuum Accessories by Scott Schram

I vacuum the filter after every use of my Roomba 880. I couldn't help but notice how pearly white the top of the original filter is, even after a month of use. I tried one of these filters and after the first use I saw dust coming through it! Also, not much was sucked from the bottom of the filter. another sign that dust is escaping. It seems to me that more dust than usual got into the dustbin, perhaps because it allows more air to pass through. However, I don't think this is good for the car and I have a hard time believing that this is due to hepa filters. Kicked them all out.
