I put this together with a $14, 20" x 20" fan from HD, and about $9 to build the light. The box was shot together with shelving I had collected for free over the past year or so. The air filter is the same size my home HVAC uses.
You can even use a sturdy cardboard box.

Looks great David - How is it that it's so clean?? LOL
Just curious - Why are you selling it?
I made mine the same way but with a lager computer monitor cardboard box.

It isn't for sale. Just wanted to show how easy it is to make a cost effective painting both. The interior is a hard gloss white finish.
