Since these filters are a set of two, they're extremely cost effective compared to a box of 100 disposable filters, which I usually find for $10-12. However, the second I started using this filter, I wondered why this product exists... I already composted my disposable filters, so this product makes me do the same thing but in a more difficult way. I still have to compost the grounds, but instead of just picking up the paper filter filled with wet grounds and plopping it into the compost bucket, now I have to take a still-hot cloth filter (because the coffee stains set in the longer you let it sit, I figured out), gingerly turn it inside out over the compost bin so I don't fling grounds everywhere, try to shake some out, and then use a dull knife to scrape the wet grounds out of the filter. It's impossible to get all the wet grounds off the filter, so some inevitably do go down the drain when I rinse the filter off. Almost every day coffee grounds end up on the floor or the counter, no matter how carefully I do this.
Bottom line: If I use this set of 2 filters for a couple years, I'll have undoubtedly saved money. But at this point, I don't think the mess and hassle of these are worth it compared to spending $12 a couple times a year.
