I believe that, during Apollo 1, the astronauts were actually in spacesuits filled with low-pressure 100% oxygen, meaning there was no toxicity risk. However, the interior of the cabin was also pure oxygen at a little more than 1 atm of pressure; I quote a source that describes why a bit further down. The reason for this is interesting.

The reason for using a 100% oxygen atmosphere was partly to avoid the risk of astronauts getting the bends during pressure changes and partly to enable a lower pressure to be used while in space, reducing the pressure difference to the vacuum outside meaning the spacecraft could be lighter. While in space, th

NASA realized that the tanks needed to hold both oxygen and nitrogen along with the associated hardware and plumbing to deliver the gases into the crew cabin came with a significant weight penalty.

With pure oxygen you can comfortably live with only 30% of sea level pressure. This is useful in spacecraft because lower pressures mean lighter weight systems. For Apollo (and Gemini and Mercury before them) the idea was to start on the ground with 100% oxygen at slightly higher pressure than 1 atmosphere to make sure seals were properly sealing.

Was pure oxygen still the environment of choice by NASA after the Apollo 1 tragedy? Yes, for several reasons: A 100% oxygen cabin atmosphere means fewer tanks, less plumbing and altogether less weight. If you are thinking they could just use compressed air, you’re forgetting that life support on a spaceship works like a rebreather.

(Credit: NASA) Fire, as we know, needs three things: a source of heat, fuel and oxygen. Apollo lunar missions had all three in spades. There was plenty of electricity running through the spacecraft, lots of material that could be fuel and a 100 percent oxygen atmosphere under pressure.

However, because a pure oxygen atmosphere had worked without incident for the Mercury and Gemini capsules, NASA decided it would be safe to press ahead with the same for the larger Apollo capsule.

First of all, life support systems were simpler. Second, a pure oxygen atmosphere employed a lower pressure, thereby allowing a thinner, lighter design. But another important reason was the fact that a 100% pure oxygen atmosphere, similar to the one used in EVA suit, could drastically reduce the preparation for extravehicular activities.

"September 9, 1962 - The first known fire occurred in the Space Cabin Simulator at Brooks Air Force Base in a chamber using 100% oxygen at 5 psi. It was explosive and involved the carbon dioxide scrubber. Both occupants collapsed from smoke inhalation before being rescued."
