DIY DIY Carbon filter

[Playboy20272]

I built this with some sticks, tape rubber bands, a bottle and a cardboard box

The filter came from a bad ass air purifier i never really use but it has one of those 100$ filter with the charcoal and all that good stuff

Any thoughts?
I made sure every crack is sealed and there is no leaks
