The Drinkwell original charcoal filters, like Lois said. They are sure to fit.

You can buy the filters for the big blue system on the website of ispring watersystems. They let you sort by big blue.

They take the filter Eureka DCF-4/DCF-18. The manual in mine said not to wash the filters, and you can get them here on Amazon for about $8, non-brand name.

It comes with a few paper filters. I ordered a permanent filter to accompany it that cost under $4.

I purchased (http://www.amazon.com/gp/product/B000LTOCSG), but am still using the filters that came with the unit. The filters are really only a paper circle, I don't believe you'll find a stainless or ceramic to replace it.

#4 coffee filters. Melitta makes them, or you can just buy a generic brand. They come bleached (white) or unbleached (brown).

I believe you can just buy the filters if you have the assembly piece the filters go in to.

Any standard coffee filter that's cheap. I generally buy 200 or 300 at a time when they're on sale. That's the wonderful thing about this type of coffeemaker: it's cheap to buy and cheap to maintain.

I order the filters from Home Depot. You can also vacuum the cartridges and the felt pre-filter and get a little more life out of them. Remember to push in the reset button by holding down the end of a paper clip into the hole till it beeps.

Depends how much water you drink. I guesstimate 2 months. You can get filters on Amazon or Ebay.

Hi....I've been getting mine from www.lumasun.com for the past 3-4 years. I originally bought the filter system from my physician, but Sharron at Lumasun can help you. Hope this helps!

You can order them from www.theperfectwater.com, Home Depot, or on Amazon. The perfect water will have every filter you need but you may find one of them cheaper elsewhere.

We use the regular Bunn filters because they are deeper than the others. You can usually purchase these Bunn filters at Walmart. -- Al
