Price of our Invention

The price of our invention is relatively cheap compared to other solutions to filter storm water. Some other filters can cost up to as much as $15,000 per filter. This is crazy high compared to our $307. Are's can cost up to 50 times less than other solutions! Ours just includes gravel, pebbles, and activated charcoal to take out the chemicals. The gravel and pebbles are $65 each and the activated charcoal is $152. Also, the air filters cost $25. This creates a grand total of $302. This would be an inexpensive way to make our storm water clean!
