These filters are perfect for the Neato BotVac D3 and should be your first upgrade when choosing a D3 or D4. The filters I received were 100% genuine Neato parts and matched perfectly. These filters allow your robot to clean more efficiently and prevent dust from entering the vacuum cleaner motor after the filter. The included main filter is a disaster and CAN stop particles the size of pepper flakes or larger. Combine these filters with a larger battery and you have a D5 or better at a much lower price.
