## Description

Enjoy a freshly made cup of coffee from your Chemex coffee maker with this set of 100 Chemex bound unbleached pre-folded square filters. Made from durable paper, Chemex filters are 20-30% heavier than competitor brands. The formulation of the filter allows the correct infusion time by regulating the filtration rate so that it is not too slow and not too fast. A good infusion of the coffee grounds gives the coffee a richer flavor while allowing precise fractional extraction that filters out unwanted ingredients that make the coffee bitter by letting only the desired flavor elements of the coffee bean through. These filters ensure even extraction as the water filters through all soils on its way to the top of the cone. Guaranteed not to burst under the weight of the liquid during filtration and will not break when you lift the bottom out. These filters are disposable filters and practical. Fits all Chemex coffee machines except CM-1, CM-1C, CM-1GH. This set of 100 Chemex bonded unbleached pre-folded square filters is the perfect addition to your Chemex coffee maker. Pack of 100, suitable for all Chemex coffee machines except CM-1, CM-1C, CM-1GH

Review: Great, These Unbleached Surely Better 🤨🔍 - These help remove trace calories and are great and look better than bleached. I’d suggest not to pre rinse with water beforehand because it just tints the brew with random added stagnant water although I do agree it could be good to sort of “wash away a bit of this and that from the factory”. What I would suggest is the following (and before doing so, clairfy with yourself if you have suspicions in processing of paper behind the scenes): 1. Use finest grind as paper removes fines anyway and it doesn’t clog entirely anyway (some things clog very easily with paper filters but the finest grind coffee usually doesn’t). You might think this sort of “has too much flavour vs caffeine soluble stuffs” but I can’t tell if that’s true or not as the root logic is murky if you sort of start thinking coarser grinds help more caffeine consumption, unless they do if fine grinds release so much taste and so little caffeine they don’t work well for more caffeine? A light roast (dark roast lighter in mass in testing) could help here if you think too much flavour vs caffeine is released on finer grinds, or if you think light roast vs dark roast has minimal differences for taste at least, use coarser grinds if you think too much taste vs too little caffeine happens with finer grinds. Honestly, I don’t know really… Yeah look is “coarse grind logic” just “insane theory” or not with this caffeine vs taste thing (idea coarser grind could release more caffeine because there’s less taste extracted and therefore more coffee/caffeine there? OR IS THAT SORT OF COMPLETELY INSANE? LITERALLY CANNOT TELL)? 2. Probably probably don’t pre rinse with water, it just seems to add a random step and a tint of ever ever so slightly stagnated water 3. ☯️☯️ Use hotter water probably, this does seem to increase extraction and given the bean is roasted above 100 deg c, it seems to make sense to use hotter water, unless you’re roasting in a frying pan with green coffee leaving trace green/super light roast flecks on the bean (although in tea you could say 100 deg c v 93 deg c is pointless as well)
Review: A Chemex MUST! - These are the only filters to use! The box is huge so it lasts ages long time! I have used the natural colour and the white ones and I prefer the natural colour especially when using with the original chemex. Fits perfectly and is super strong, the filter can handle multiple pours. I’ve tried the washable filters but you don’t get the quality and same slow drip the chemex is designed for so for coffee lovers- and using these filters is the only was to get the perfect cup!

## Features

- Step 1: Place the funnel in the top portion of the CHEMEX coffeemaker, with 3 layers on the groove side. The groove is an air vent (and also the pouring spout) and allows air to escape from the lower portion of the coffeemaker, letting the coffee filter
- Step 2: Put coffee in the filter paper cone. Use one heaping tablespoon per cup of coffee (adjust to personal taste if needed after first brew). Refer to brewing instructions for remaining steps.
- THICKER: 20-30 percent thicker than the competition, specialty fiber filter design keep bitter elements, oils, and grounds in their place (and out of your cup)
- Fits all CHEMEX Coffeemakers except CM-1, CM-1C, CM-1GH
