How to add custom filter to the existing ones?

Dear all, I’m really new on Magento and I’ve to implement a custom filter on numeric value that involves more than one attribute. In other words, if a product have attributes A and B, I need to add filter on something like (A + arg1)*(B+arg2)<arg3, where arg1, arg2 and arg3 are input numeric values. I found the addExpressionAttributeToSelect to apply the selection to the product collection but I’m not able to retrieve and take into account the already applied filters, e.g. the selected attributes in the Shop By section, returning the complete filtered product list.
I’m using Magento CE.
Can someone help me?
