Any bottle or bag with a 64mm opening will work. Nalgene was the first to standardize this, calling it their 'wide-mouth' bottle. You will find the 64mm 'wide-mouth' on many bottles from stainless steel, to aluminum, to various polyurethane and lexan-type bottles. The best thing about the Hydromedary, Dromlite, and Dromedary bags is that they will hold much more water at a significantly reduced packed weight and volume. By getting the Spigot Lid accessory, you can turn your hydration system or folding bottle into a camp sink. It is extremely versatile to have around camp. Highly recommended!

I personally don't have one of those filters, but I've seen reviews of these bags on other sites that have mentioned using them together easily.
