Filter for report


I have a module with a list of products with different ages. I want an end user to be able to select whether from a list to show all products < 3 years, >= 3 years and >= 5 years. 


In my module, I have created booleans to check for each of the above.  

I have also created a list for the 3 periods.  I'm a bit stuck now - can someone please assist?
