Review on 🔍 Gazeer 20-Pack High-Efficiency Replacement Filter for iRobot Roomba I&E Series i7 i7+ i8 i3 i6+/Plus E5 E6 E7 Vacuum Cleaner by Molly Hoffman

Quantity 20 is suitable for periodic replacement of the old filter. The filters are of good quality and will withstand multiple vacuum cycles. I usually replace the filters after 8-10 uses and clean them after each use. You will eventually need to replace the filter when the dirt has penetrated the filter media, reducing the effectiveness of the vacuum suction.
