I’ve used them a couple of times. Yes they are good, but susceptible to varying quality if not cleaned well, and I’ve never kept one in a good enough condition for long enough for it to be a real cash saving (given they aren’t that cheap to start with).
Anyone tried cloth filters? Like this: https://theclothfilter.co.uk/shop/p/wave
Just got one but tried it on shit coffee at work, so none the wiser really.
I'm a big fan of metal filters on the aeropress, I guess this is the closet thing on drip? At the least it saves the £10-15 a pop on Kalita filters.
Now to wait till a work colleague throws it away.
