Tanfelix was born on September 21, 1998, in Dasmariñas, Cavite. He is the eldest of the two children of Mary Grace Torrejos and Gary Tanfelix who are both educators and mountaineers. Although they live in Cavite, where Tanfelix attends regular school, the family also keeps a home in Parañaque to lessen Tanfelix's traveling time when he is filming. Tanfelix finished high school at Cavite School of Life (Dasmariñas Campus) and is now currently studying entrepreneurship at De La Salle University-Dasmariñas. Aside from acting and schooling his sports and hobbies are basketball, wakeboarding and hiking. His passion for basketball is evident when he became one of the varsity players in his high school years.
Tanfelix is opposed to premarital sex. He is also hired by the Commission on Population (POPCOM) as celebrity ambassador for U4U, a youth initiative whose stated mission is to provide Filipino teenagers with critical information on delaying sexual debut and preventing sexually transmitted infections.
