🔍 Hongfa Replacement Roomba i7 i7+ i6+ Filters, 18 Packs Replacement Parts for i-Robot Roomba i7 7150 i7+/i7 Plus E5 E6 i6+ E7 i3 i3+ i4+ (4552) Vacuum, Roomba i & e Series Replenishment Filters Review

I've been using the 12 pack I bought for 7 months now. They fit perfectly but get a lot dirtier and there is a lot more hair, dirt and debris in the bin. They don't seem to filter and they are always very dirty. I will not buy them again for these reasons. iRobot filters are better and last longer, and while they're more expensive, I think they do a better job.

So it may not be a HEPA filter but it actually causes dirt to build up on the back of the bin unlike the original filters, which either seemed to rise a bit in the middle or just got stuck in the slide and activated the "garbage full" alarm when it was nowhere near full. They're a little firmer than the original, but so far so good. And I don't mind changing them more often considering the price.

These filters clog up very quickly - I don't know what they are made of compared to the iRobot brand but now we keep getting cart empty and other error messages. iRobot brand filters last a very long time, only lasting a time or two before clogging. The brush that came with it doesn't seem to do anything. You can't use a handheld vacuum to clean the filters, which is something we've always been able to do with the iRobot brand. We are back to very expensive filters. I don't want them to destroy
