Review on 🔍 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 by Amy Smith

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.
