What version of PHP are you on?
filter_var is a PHP function available in version 5.2+
http://php.net/manual/en/function.filter-var.php
I cannot imagine a reason why that would fail but I will consider removing it.
Who’s your web host? Would you mind asking them if they have any idea why that native PHP function would not work on their server?
They advertise PHP 5.1 to 5.6 here:

So we need a definite confirmation that your server is running at least PHP 5.2, the minimum version required by WordPress.

Thank you all, the answer came from hosting support:
In this case, you need to connect the PHP filter extension.
You can connect the extension through the hosting control panel:
– log in to the control panel (https://hosting.nic.ru), using your contract number and password;
– go to the section “Web server” – “Manage modules”;
– Click on the link “PHP (configure the module);
– in the “PHP module extensions” block, click the “Manage extensions” link;
– Select the checkbox “Show all extensions”;
– Find the desired extension in the list that opens, check its box and save the changes.
I’m glad you got it working. I wasn’t aware that could be disabled. Thanks for sharing the solution.
