    ->addFilter('country','Nepal');

You can use diffrent condition like below reference from this.

$collection = Mage::getModel('catalog/product')->getCollection();

Is Equal To

$collection->addAttributeToFilter('status', array('eq' => 1));

Greater Than

$collection->addAttributeToFilter('price', array('gt' => 3));

Contains – with % wildcards Is NULL

$collection->addAttributeToFilter('sku', array('like' => 'DVD%'));

$collection->addAttributeToFilter('entity_id', array('nin' => array(1,2,12)));
