It’s an amazing filter – makes great coffee. But the cone is very fragile, and I keep breaking it.
Whenever I go camping or travel, I always come back with a crack.
I really wish it was a bit stronger.
On the other hand, there is a ten-year warranty and ROK send a replacement not question asked.
This is my 2nd W1 - not because there's a problem with the 1st, but to make sure one is always to hand. Once you find a comfortable way to manipulate the paper filter into place without poking a hole in it, the brewing becomes more and more enjoyable. I use Melitta 1 x 4 papers as it gives more to work with and make sure there's a bit of slack around the pointy bit. A bit of origami while the kettle boils is all part of the enjoyment. Whatever pouring technique you use, the flavour extraction is impressive. The only thing that doesn't work for me is the metal ring, but I do now have two napkin rings...
Hi Robert, thank you for sharing your detailed experience! We're glad you're enjoying the brewing process and appreciate your tips. The ring tool can help press down the paper when placed into the W1. If you keep it in place before rinsing the paper, it creates a tight fit. But they also make great napkin rings !
The W1 Filter is very effective with slow filtering for an excellent cup of coffee.
Works well so am pleased with the product
This is the second W1 Filter that I've purchased and it's honestly great. It consistently provides flavorful and nuanced cups of coffee without the need to have everything dialed down to the last degree or needing a gooseneck kettle (convenient while traveling). You can get as specific as you want with it or just splash that water right into it. Big recommend.
Disappointed to notice upon arrival what seems to be bamboo composite material which is currently being investigated for potential impact to human health: https://food.blog.gov.uk/2024/07/30/what-are-bamboo-plastic-composites-and-why-they-shouldnt-be-used-for-food-or-drink/
Hi Panda Scientist, You are quite right to question the safety of bamboo composites. We did also. Bamboo composites generally use Melamine as a binding agent. Melamine has been used for a generation for children’s plates and cups as it’s very durable. The latest findings indicated that some Melamine resins may leach Formaldehyde at higher temperatures. We heavily tested our bamboo and found a variant we are confident with. See more in W1 FAQs here - https://us.rok.coffee/pages/help
Since I purchased the espresso machine, I figured I'd try the pour over too. It is a fine device. It didn't supercede the taste of my Kalita and it takes more time getting the filter in, so I will probably just give it away. If you don't already have a pour over, this is a fine unit.
This makes excellent V60 style filter coffee but is much quicker than the standard draw down due to the clever folding.
Simple to use, easy to clean.
I love it.
great product - it does need good strong filter papers. The ones that came with it were fine, other ones I used (Melitta) split
so much better than a standard v60, getting so much more flavour and notes from the coffees i’m putting throughout it!
