From 21 independent Baryon Acoustic Oscillation (BAO) measurements we obtain the following sum of masses of active Dirac or Majorana neutrinos: src="Edit_b9e46fd6-6ae7-4ce7-900a-18da620bed0b.bmp" alt="" />, where src="Edit_845cd944-4683-4d80-890a-3a5cc234199e.bmp" alt="" />and src="Edit_be40e906-f818-46ac-ba08-5ef4037f3026.bmp" alt="" />.
