Change Magento collection to show only grouped products

I'm trying to modify Magento (1.7.0.2) collection to show only grouped products in the product list. I've tried to do this with addAttributeToSelect or addAttributeToFilter like this

$_productCollection=$this ->getLoadedProductCollection()
->addAttributeToSelect('*')->addAttributeToFilter('type_id','grouped');

or

$_productCollection=$this ->getLoadedProductCollection()
->addAttributeToFilter('type_id', array('eq' => 'grouped'));

but it's not working now with this version of Magento.

Anybody knows how can I get it working?

Filters not being applied often happens when the production is already loaded.

Try doing a $_productCollection->clear() before you iterate across the collection. Preferably though, find a place to update the collection before it is loaded.
