Magento - Add filter to getLoadedProductCollection()

In my magento store (ce-1.9.0) I have setup a custom product attribute:

custom_depth_check

And the attribute has the setting of

Used in Product Listing : Yes
Used for Sorting in Product Listing : Yes

I now need to filter any getLoadedProductCollection() with this attribute. The attribute will either be set at:

null
0
1

I need to filter all instances of getLoadedProductCollection() so that it will EXLCUDE any products with 

custom_depth_check : 1

I have tried to clear and reload like so:

$_productCollection=$this->getLoadedProductCollection()
->clear()
->addAttributeToFilter('custom_depth_check', array('neq' => 1));

But that results in an empty collection. I also tried adding ->load() at the end but again nothing comes up.

The collection is loaded in the file: app/code/Mage/Catalog/Block/Product/List.php in the function: _getProductCollection()

Do a local ovveride by copyng that file in local folder app/code/local/Mage/Catalog/Block/Product/List.php

and add your new filters just before the line

$this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

your code will be like:

$this->_productCollection->addAttributeToFilter('custom_depth_check', array('neq' => 1)); //Your new filter
$this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

best regards Giuseppe
