Easy, efficient, economic

Thick and nice

Fast but sturdy filters

I generally order the pre-folded unbleached squares, but I thought I would try these this time.

They are easy to fold, but I agree with the other reviews that the flow rate is much faster than the bleached filters - I found it faster than the squares.

With a finer grind and a more controlled pour, these still make delicious coffee, but I recommend the squares for a better experience.

Just have to be careful

These are good straight-forward filters, but you have to be careful when dialing in the grind and pour time compared to the bleached ones, as the bleaching process does affect the paper in more ways than colour. If you keep that in mind, there's no reason why you can't get the exact same results as your "normal" white filters. Only reason it's 4 instead of 5 stars from me is that I prefer not to use single-use disposable items.

Different flow properties

I purchased these after going through several boxes of the bleached filters. The first thing I noticed when folding them was how thin they were. After brewing my first batch of coffee I was surprised with how fast the coffee was filtered through these filters. Brew time was nearly cut in half and the coffee seemed much thinner. Perhaps I need a finer grind, which I will try next, but didn't expect such a different cup of coffee. I'll continue to play around with the grind and pour rate, but as of now I'll definitely be getting the bleached filters next time.

Hi Chris! We've tested this, and it did shave around 25 seconds off the brew time (4:00 vs 4:25) - we do suggest playing around with the grind and making it a bit finer until you find something you like!
