The Neutop replacement filters have received mixed reviews from users. Some have found that the third-party replacements wear out faster and are less effective than the original Ecovacs brand filters. They are seen as a cheaper alternative upfront, but potentially more expensive in the long run due to the need for more frequent replacements. However, other users have reported that the Neutop filters work just as well as the OEM filters but at a lower cost. Users appreciate the ease of cleaning and the convenience of having several filters to swap out regularly.
Overall, the reception for Neutop replacement filters is mixed, with some users finding them to be a cost-effective alternative to the original brand, while others have concerns about their durability and performance compared to the OEM filters.
