Storm drain filter with removable debris tray

A drain filter, comprising:

• a bottom media tray including an outer rim, a concentric inner rim, a depressed peripheral media trough comprising a continuous concave surface connected between and projecting below said outer rim and said inner rim thereof for receiving filter media, and a central overflow opening inward of said depressed peripheral media trough for draining excess runoff, said depressed peripheral media trough including a perforated surface;
• and
• a top debris tray including an outer rim, a concentric inner rim, a depressed peripheral debris trough comprising a continuous concave surface connected between and projecting below said outer rim and said inner rim thereof for collecting debris, and a central overflow opening inward of said depressed peripheral debris trough for draining excess runoff, said depressed peripheral debris trough including a perforated surface, said debris trough of said top debris tray being narrower and shallower than said media trough of said bottom media tray, said top debris tray being removably positioned within said bottom media tray thus defining a media receiving chamber in between for enclosing said filter media, said top debris tray being removable from said bottom media tray for emptying said debris and enabling inspection and replacement of said filter media, said depressed peripheral debris trough for holding said debris securely therein while said top debris tray is being lifted, so that said debris is prevented from falling into said bottom media tray.

A drain filter, comprising:

• a bottom media tray comprising a closed outer wall, a closed perforated inner wall, and a bottom connecting lower ends of said outer wall and said perforated inner wall thereof, a peripheral media trough defined between said outer wall and said perforated inner wall for receiving filter media, and a central overflow opening defined within said perforated inner wall for draining excess runoff, said perforated inner wall for directing runoff into said central overflow opening;
• and
• a top debris tray comprising a closed outer wall, a perforated tapered annular bottom with an outer edge connected to a lower end of said outer wall and an inner edge substantially higher than said outer edge thereof, a depressed peripheral debris trough defined between said outer wall and said perforated tapered annular bottom for collecting debris, and a central overflow opening inward of said annular bottom for draining excess runoff, said debris trough of said top debris tray being narrower and shallower than said media trough of said bottom media tray, said top debris tray being removably positioned within said bottom media tray, said perforated slanted bottom of said top debris tray spaced above said bottom of said bottom media tray thereby defining a media receiving chamber in between for enclosing said filter media, said top debris tray being removable from said bottom media tray for emptying said debris while leaving said filter media in said bottom media tray, said peripheral debris trough of said top debris tray for containing said debris and preventing said debris from falling out during removable of said top debris tray from said bottom media tray.
