In The 100, all of the station's population descends to Earth because the oxygen generating system of Ark had failed.

Later, Murphy, Bellamy, Monty, Raven and others went up there and spent 6 years before descending again.

How can they survive without oxygen for 6 years?

According to the100.wikia.com, they installed oxygen scrubbers in S04E13. The relevant part from that wiki (emphasis is mine):

"Then, Murphy, Emori, Harper, Monty, Raven, Bellamy, and Echo get onto the Ark, but Raven is low on oxygen. Murphy and Emori decide to share theirs along with everyone else. Meanwhile, Monty instructs Bellamy to connect the oxygen scrubber to the conduits on the Ark."

    If such an easy solution is available why did the space stations descended down to earth in the first place?

  • @Sonevol I don't know for sure, but I think they needed supplies from that lab (don't have a source atm, but that's how I recall from watching it a year ago or so).

    I haven't seen this episode yet, but I'm inferring that teh oxygen scrubber in question came from the vessel they used to return to the Ark - it wasn't on board before. Also, one oxygen scrubber might be good enough for 7 or 8 people, but it probably wouldn't be enough for everyone that was up there before the descent.
