Remember, it's 5% MAX health increase. So your 120% bonus health get increased by another 5%, basically if you had 100 HP with health+120% and the artifact you'd have (100x2.2)x1.05= 220x1.05=231 HP, now imagine you had a 200HP warframe with 240% bonus HP AND the artifact, it's actually quite a bit.
