Wild Orchid also recorded cover versions of "Our Lips Are Sealed" and "You're No Good".

The album was released in September 1998 and coincided with their stint as Guess spokespersons and models and as hosts of the new Fox Family reality show Great Pretenders, in which kids and teens of all ages lip sync their favorite songs while competing for prizes.

They went on a promotional tour throughout the U.S. and were guests on Donny and Marie, where they performed "Be Mine" (the album's lead single).

The group even made a guest appearance on the Beverly Hills 90210 episode "Beheading St. Valentine" where they performed "Declaration" and "Come As You Are" at the fictitious Peach Pit After Dark.

Since Oxygen was a commercial failure, rumors were spread in 1999 about the group returning to the studio to record a new version of the album.
