Используются функции trim и substring_index. Пример — нужно получить id которые хранятся в формате '82','84','87':

SELECT * FROM `filters_vars` WHERE `shown`=1 AND `filter`=37 AND `id` IN (SELECT TRIM(BOTH "'" FROM (substring_index(`value`,",",1))) AS `values` FROM `filter_values` WHERE `value`!="" AND `filter`=37 AND `item` IN (SELECT `id` FROM `catalog` WHERE `shown`=1 AND (`parent`=76 OR `id` IN (SELECT `item` FROM `catalog_dub` WHERE `razdel`=76))) GROUP BY `values`) ORDER BY 'pos';
SELECT * FROM `filters_vars` WHERE
    `shown`=1 AND `filter`=37 AND `id` IN (
        SELECT TRIM(BOTH "'" FROM (SUBSTRING_INDEX(`value`,",",1))) AS `values` FROM `filter_values` WHERE
            `value`!="" AND `filter`=37 AND `item` IN (
                SELECT `id` FROM `catalog` WHERE `shown`=1 AND (`parent`=76 OR `id` IN (SELECT `item` FROM `catalog_dub` WHERE `razdel`=76))
            )
        GROUP BY `values`
    ) ORDER BY 'pos';
