Chemex Bonded Circle Pour-Over Coffee Filters — 100 ct Pack, Thicker Fiber for Cleaner, Brighter Cup

These are Chemex Bonded Circle paper filters — a 100-count pack of premium, multi-layered filters engineered to deliver a cleaner, brighter pour-over cup by trapping oils, fines, and bitter particulates.

Designed specifically for Chemex pour-over coffee makers (compatible with all models except CM-1, CM-1C, and CM-1GH), these bonded circle filters use a thicker specialty fiber construction that removes unwanted sediment and oils while preserving flavor clarity. The pack comes in exclusive packaging and contains pre-cut circular filters that fold into a funnel shape for an airtight fit in the brewer. They’re intended for home or light commercial use where consistency and an uncluttered cup profile matter.

How do I prepare and fold the Circle filter correctly?

Folding the Chemex Circle filter is simple and creates the proper funnel shape to sit securely in the brewer. Proper folding directs water flow, allows air to escape through the groove, and supports an even extraction.

• Fold the round filter in half, then fold it in half again making a cone.
• Place your finger between the third and fourth layers and open the cone into a funnel shape.
• Set the funnel with three layers on the groove side so the groove serves as the vent and pouring spout.

What brewing ratio and grind work best with these filters?

Start with a standard guideline and adapt to taste: Chemex recommends roughly one heaping tablespoon of ground coffee per cup — adjust for strength after your first brew. Use a medium-coarse grind to maintain flow rate and prevent over-extraction with the thicker filter material.

• Begin with one heaping tablespoon per 6-ounce cup; tweak to preference.
• Use medium-coarse grind to balance extraction and flow through the thicker paper.
• Pre-wet the filter to remove paper taste and warm the brewer for even brewing.

How do these filters change the cup compared with standard paper filters?

Because these Chemex bonded filters are 20–30% thicker than many competitors, they trap a higher proportion of oils and fine particles, resulting in a clearer body and pronounced acidity and aroma. Expect a cleaner mouthfeel and a cup that highlights brighter, more defined flavor notes.

• Thicker, specialty fibers hold back oils and fines for clarity in the cup.
• Removes bitter micro-grounds, reducing sediment and harshness.
• Produces a lighter-bodied brew that emphasizes delicate flavors.

Who is this for? These bonded circle filters suit home brewers and coffee enthusiasts who use Chemex brewers and prefer a crisp, clean cup with minimal sediment. They’re also good for cafes wanting consistent pour-over results and for anyone who values an easy-to-fold paper filter that fits securely and supports controlled extraction. Note: not compatible with Chemex CM-1, CM-1C, or CM-1GH models.
