I created a new page with module.Settings are:
Theme/app/etc/modules/Theme_Newpage.xml

<?xml version="1.0"?>
<config>
<modules>
    <Theme_Newpage>
        <active>true</active>
        <codePool>local</codePool>
    </Theme_Newpage>
</modules>
</config>

Theme/app/code/local/Theme/Newpage/etc/config.xml

<?xml version="1.0"?>

<config>
    <modules>
        <Theme_Newpage>
            <version>0.1.0</version>
        </Theme_Newpage>
    </modules>


    <frontend>
        <routers>
            <Theme_newpage>
                <use>standard</use>
                <args>
                    <module>Theme_Newpage</module>
                    <frontName>newpage</frontName>
                </args>
            </Theme_newpage>
        </routers>
        <layout>
            <updates>
                <newpage>
                    <file>newpage.xml</file>
                </newpage>
            </updates>
        </layout>
    </frontend>
</config>

Theme/app/code/local/Theme/Newpage/controllers/IndexController.php

<?php

class Theme_Newpage_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {

        $this->loadLayout();

        $block = $this->getLayout()->createBlock(
            'Mage_Core_Block_Template',
            'newpage',
            array('template' => 'newpage/content.phtml')
        );

        $this->getLayout()->getBlock('root')->setTemplate('page/2columns-left.phtml');
        $this->getLayout()->getBlock('content')->append($block);
        $this->_initLayoutMessages('core/session');
        $this->renderLayout();
    }
}

?>

Inside of this page, in content section i have displayed my products.Left side is empty because is set as 2columns-left.phtml.I want to display filters of my products there.I created a new layout newpage.xml and there i have:

<?xml version="1.0"?>



<layout version="0.1.0">

    <newpage_category_layered translate="label">
        <reference name="root">
            <action method="setTemplate"><template>newpage/content.phtml</template></action>
        </reference>
        <reference name="left">
            <block type="catalog/layer_view" name="catalog.leftnav" template="catalog/layer/view.phtml"/>
            <!--
            <action method="unsetChild"><alias>category_filter</alias></action>
            -->
        </reference>
    </newpage_category_layered>
</layout>
