The burp filtering device has the body of a writing pen, with an intake port at the upper end of the body, a plurality of exhaust ports adjacent the writing tip, and a filter disposed within the body. The filter may be made of activated charcoal or other media for filtering eructation odors. In use, the user holds the upper end of the pen body to his lips, releases the suppressed burp, and the filtered gas is exhausted through the ports at the writing tip.
