Question: Which filters fit the 1.3 gallon Natural Home compost crock?
Document: Great size, fits the degradeable bags, no rust issues. Natural Home filters found on Amazon are the only filters I have found that fit. Others are too small. NH compost bin looks great on the counter with my other stainless steel cannisters. This little canister does everything except carry itself out to compost bin.
I'd been using an old ice bucket for years for my compost but I knew I needed a metal container. My criteria when shopping was a stainless steel container the right size to fit under the sink. This Natural Home Stainless Steel Compost Bin is perfect. I know it is pretty enough to be on the counter, but I prefer it to be under the sink and it fits perfectly. Amazon to the rescue ... again!
I purchased the Natural Home composting bin. It's a great size & the filter worked perfectly, no smell. It's time to replace & twice I have purchased the wrong size charcoal filter. The one included with the product review does not fit the top properly. So I measured & ordered again.
Love this bin. Looks good, can hold a few days of waste and contains odors well. great purchase but make sure when ordering to get the correct replacement filters!!! Natural Home 2-Pack Replacement Composter Filters
Didn't realize 1/2 a gallon was so big, bigger than I needed but that's on me. Very solid construction and the lid fits snuggly. The lid holds the charcoal filter handily too. I used this to replace the Oxo countertop bin I recently bought - that one was about 1 liter in size but I use bags and they never seemed to fit right into the container mainly because that one is made to be used without bags.
Because it is past the return period, Amazon said I would have to contact the manufacturer, Natural Home. I am going to ask for a refund. We'll see.
Nice size .... Much better for us than a 1 gallon bin since we consume a lot of fruits and veggies. Durable as well. We keep our bin in the appliance cubby but it is nice enough to keep out on the counter.
Thought a stainless steel compost bin would be a good thing. It's not since every single finger print shows on the lid, especially if you are trying to put something in it and haven't rinsed your hands. In addition, I cannot find the proper size filters for it, so am having to use ones that do not fit properly. And, finally, even though the bin is emptied often, washed and dried, there are spots of rust on the inside.
We've had this bin for more than a year now, and it's holding up great -- it looks new and has no problems. We use those green compostable 3 gallon bags with it. No rust issues yet. We do use a rubber band around the outside to hold the bag in place, and we wash it once a week or so by hand. The carbon filter has lasted forever, probably because we don't over-fill the bin and we wash the filter with hot water occasionally.
Looks great in my kitchen with my stainless steel appliances. I ordered extra filters and haven't needed to change my filter yet. It's been about 3 months.
