Organic Cotton Coffee Filter


The best and highest quality, reusable organic cotton filter!

Organic cotton is by far the best coffee filtering material for these main reasons:

  • Takes away the weakness of inconsistent grind sizes because it can filter out any grind size (from fine to coarse). This means that everything from inexpensive blade grinders to the best espresso grinders can be used in conjunction with the ACE Brewer to yield amazing cups.
  • Unlike with paper, organic cotton does not impart any flavour to the finished coffee and so the only taste in your mouth is your pure hand-crafted brew!
  • Non-toxic, reusable and doesn’t require any special cleaning (just a quick rinse after each brew!)

Blending old world coffee traditions with new technology and brewing knowledge; our organic cotton filters deliver the richest and best-tasting cups of coffee.  For best results, use with our Two-Step Steep & Filter® process.

Organic cotton coffee filters are ideal for a multitude of reasons:

  • Better for the environment (made from organically grown cotton, cuts down on waste from disposable filters).
  • Made from the highest quality, certified organic cotton/fleece blend, which is known for its durability (lasts for 2-3 years).
  • Allows for quick and even filtration.
  • Does not require a specific grind particle size for brewing coffee (so you don’t have to worry about your type of grind).
  • Allows for the full spectrum of the coffee flavour (natural oils; including fatty molecules) to pass through the filter and into the cup (paper takes away some of the fatty acids and volatiles that affect a coffee’s natural flavour; also free of the “papery” taste that results from paper filters).
  • Hand-made locally with love by a dear friend of Merchants of Green Coffee.


  1. How long will the organic cotton filter last me? Our organic cotton filters last 1-3 years (depending on how often you use it) before the edges of it start to wear out and develop holes … kind of like your favourite old t-shirt! You can keep using it as long as it’s holding onto its stainless steel filter basket, but we suggest replacing it every 1-3 years in order to keep it fresh and performing at its best.
  2. How do I clean the organic cotton filter? Our organic cotton filters are very easy to clean; just shake off the bulk of the grinds into your compost bin and rinse the filter with running water from your sink after each use. (Coffee grinds actually help unclog drains, by acting as tiny “eroders”, and do not contribute to drain clogging).
  3. How should I store the cotton filter? A wet filter can produce mould if left moist for too long in a tightly sealed, non-breathable container. If you are using your organic cotton filter every day or every few days the best method of storage is to simply leave it sitting out on your countertop.If you are not using your organic cotton filters for longer than 3-5 days at time, it’s best to moisten the filter and store it in the freezer until next use. Once out of the freezer, a quick rinse with warm water will have it ready for use again. (The reason for keeping the cotton in the freezer is to lock in water moisture so that the cotton doesn’t dry out for too long causing any oils left in its fibers to go stale (rancid). Spent coffee oils, when exposed to air for long periods, will turn stale and may impart unwanted flavours to the cotton).
  4. Will the filter develop any bad bacteria? No, the filter keeps itself extremely clean as long as you use it regularly and rinse it out after each brew. And, don’t use it for anything but coffee! We also recommend pouring a bit of hot water through it before each new brew (just to warm your cup and rinse out any remaining flavour from your last brew).
