The upper layer can be filled with unfiltered tap water, the lower layer will get clean water after filtered. Because it does not require electricity, it can be used indoors and outdoors. NOTICE: When the bottom bucket is full of filtered water, please do not add tap water to the top bucket or it will leak out.
