1. An oven comprising:
a cooking chamber;
a steam generator in fluid communication with the cooking chamber, the steam generator configured to transform water into steam for delivery to the cooking chamber;
a water reservoir in fluid communication with the steam generator, the steam generator further configured to draw the water from the water reservoir to be transformed into the steam;
a water fill assembly in fluid communication with the water reservoir and configured to accept water from a source external to the oven that is subsequently deposited into the water reservoir; and
a filter assembly disposed in fluid communication between the water reservoir and the water fill assembly, the filter assembly comprising
a tubular element comprising (i) an exterior surface, (ii) an interior surface defining an interior flow channel, (iii) desiccant disposed within the interior flow channel, (iv) a first end, (v) a second end disposed vertically below the first end, wherein the interior flow channel extends from the first end to the second end, (vi) a first opening into the interior flow channel disposed at the first end in fluid communication with the water fill assembly, (vii) a second opening into the interior flow channel disposed at the second end in fluid communication with the water reservoir; (viii) ridges that are outwardly extending and concentrically disposed at both the first end and the second end, and (ix) an O-ring disposed at each of the first end and the second end between a pair of the ridges, wherein both the O-ring disposed at the first end and the O-ring disposed at the second end are disposed radially outward relative to the interior surface defining the interior flow channel.
