That's clear so far.

why do you do it inside your view? Isn't the controller responsible to 
trigger the repository and then assign the products as variable to the view?

function filterAction($filter,...) {
	$filteredProducts = $this->productRepository->findByCriteria($filter);
	$this->view->assign('products',$filteredProducts);
}

So your view doesn't have to deal with filtering the products in the 
repository - the view is only responsible for rendering those products 
and rendering the links to filter stuff (maybe by using dropdowns for 
filtering?).

I think I'd pass the pure settings/filter options by array as long as 
you don't need any logic inside the filter settings (like dependencies: 
if filter "x" is set, then option "y" doesn't have this or that entry, 
so only return those values to the view).
