A drain guard device for preventing particulates from entering a drain. The drain guard device includes a ring member having an outer circumference and an inner circumference. A groove extends radially along the entire inner circumference. The groove is dimensioned to removably receive a strainer. The ring member is a flexible flat annular ring having a uniform width between the outer circumference and the inner circumference. In use, the drain guard rests over a drain, wherein the lower side of the ring member is configured to frictionally engage an upper side of a surface, such as a floor or sink. The lower side of the ring member is configured to form a suction seal with the upper side of the surface, wherein both the strainer and ring member can be easily removed from the surface by hand when desired.
