Magento2 – Filter Product Collection by Attribute

try this code

$manufacturerLabel = 'Bosch';
$manufacturerValue = 10; //assumed value of manufacturer Bosch
$productCollectionFactory = $objectManager->get('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('*');
$collection->addAttributeToFilter('manufacturer', $manufacturerValue); // here filter with manufacturer value instead of label 
$collection->setCurPage(9);
$collection->setPageSize(100);

In Magento 2, yourModule/etc/di.xml

<type name="Magento\Catalog\Model\Layer">

<plugin name="exclude_no_image_product" type="yourCompany\yourModule\Model\Rewrite\LayerPlugin"/>

  </type>

Add file yourCompany\yourModule\Model\Rewrite\LayerPlugin.php

<?php
/**

 * See COPYING.txt for license details.
 */
namespace yourCompany\yourModule\Model\Rewrite;

/**
 * Catalog view layer model
 *
 * @api
 * @SuppressWarnings(PHPMD.LongVariable)
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 * @since 100.0.2
 */
class LayerPlugin
{ 
    /**
     * Retrieve current layer product collection
     *
     * @return \Magento\Catalog\Model\ResourceModel\Product\Collection
     */
    public function aroundgetProductCollection(\Magento\Catalog\Model\Layer $subject, \Closure $proceed)
    {
        $collection = $proceed();        
        $collection
        ->addAttributeToSelect('*')
        ->addAttributeToFilter('small_image', array('neq' => 'no_selection'))
        ->addAttributeToFilter('small_image', array('neq' => ''))
        ->addAttributeToFilter('small_image', array('neq' => null));
        return $collection;
    }    
}
