Removing filter boxes on category page

Right, I have removed the filters from the category page by deleting <?php echo mp_products_filter(); ?> from mp_category.php.

I also have added some code I found to automatically replace "our Products" with the category name.

My problem is as follows, when I press the search button the "our Products" appears and so does the drop down filter boxes. How can I fix this.
The link below shows how the page looks before search is pressed.

The link below shows the page after search has been pressed

Hope someone can help
