A:Answer Simple filtration will not guarantee the water meets health code potable water standards, and thusly, it is not safe to drink. Everything in your air, from dirt, mold, bacteria, viruses, smog, and everything in between will collect on the moisture that builds up on the coils and continue to drain into the condensate pan. Those coils allow all sorts of growth to occur and without a full water treatment system, there is absolutely no way to guarantee that you or animals won't get sick. You can use it to water plants and such, but even then, there is a small chance you could introduce a mold to them that could kill their roots and such. At the end of the day... caveat emptor
