Review on Authentic iRobot Replacement Parts - High-Efficiency Filter for Roomba e, i, and j Series (3-Pack) - 4639161 by Joaquin Bennett

We use them on our Costco Roomba e6 series and they work great with them. They are advertised as iRobot genuine parts and nothing about them makes me believe they are generic. They look identical to the original filter that came with my Roomba. I included a photo next to a very, very dirty, disgusting original before I sprayed it clean and one of those replacement filters. They are the same size, shape, even with "iRobot" written on the side. Also, we run our rumba once or twice a day on about 700 square feet of tile and 150 square feet of carpet in the bedroom, and we have two dogs (Chihuahua and German Shepherd) and we take our filter out once or twice a week and spray it with our kitchen sink sprayer. They held up very well after a month of spraying, reusing and swirling, and the suction power on our Roomba is still amazing. I'll probably throw away any filter after we've sprayed it 5-10 times or when it shows signs of wear. But I have to say they are doing a great job with all the dust, hair and sand that dogs bring in every day! They're expensive, but they can be sprayed, and that's the price you pay to buy a paper filter room.
