What customers say
Customer sentiment for the Chemex FS-100 bonded square filters is overwhelmingly positive, reflecting their critical role in achieving the signature clean, bright cup of coffee that Chemex users seek. Reviewers consistently highlight the superior filtration capabilities provided by the thick, specially bonded paper. This thickness effectively removes fine sediments and oils, resulting in a remarkably clear and non-bitter brew, which is the primary reason for the high loyalty. Users appreciate the perfect fit of the square filters (290x290mm), noting that they are easy to fold and seat correctly in the brewer. The filters are considered essential, not merely optional, for the Chemex system, and many users explicitly state that generic alternatives simply do not compare in terms of taste neutrality or structural integrity. However, the primary point of friction is the cost. These filters are positioned at a premium price point, leading some customers to express frustration regarding the ongoing expense, especially for daily users. Despite the cost concern, most customers ultimately deem the filters a necessary investment to maintain the quality of their coffee experience, suggesting that the perceived value outweighs the high price for dedicated enthusiasts. Overall, the sentiment is one of high satisfaction driven by performance and quality consistency, cementing the filters as a non-negotiable component of the Chemex brewing ritual.
Know before you buy
These filters are unbleached. They are made from high-quality, flavor-neutral paper designed to ensure no papery taste interferes with your coffee.
The square shape allows you to fold the filter to fit your specific Chemex brewer perfectly. This design also creates a thicker layer of paper on one side, which helps regulate the flow rate and ensures consistent extraction.
No, these are specifically engineered for Chemex glass brewers. Their size and thickness are optimized for the Chemex brewing process and will not function correctly in standard basket-style or cone-style drip machines.
Yes. The proprietary bonding and thickness of Chemex filters are designed to remove almost all sediment and bitter oils. This results in a noticeably cleaner, brighter, and more transparent cup compared to standard thinner paper filters.
To fold, simply fold the square in half, then in half again to create a smaller square. Place it in the Chemex funnel with the triple-layered side facing the pouring spout to prevent the filter from sealing against the glass and blocking airflow.
