use _.mixin to extend a omitDeep method:

_.mixin({
    'omitDeep': function(obj, predicate) {
        return _.transform(obj, function(result, value, key) {
            if (_.isObject(value)) {
                value = _.omitDeep(value, predicate);
            }
            var doOmit = predicate(value, key);
            if (!doOmit) {
                _.isArray(obj) ? result.push(value) : result[key] = value;
            }
        });
    }
});

var my = {
    "key1": {
        "key2": {
            "key3": [null, {
                "key4": "string",
                "key5": true,
                "key6": null,
                "key7": 8,
                "key7": undefined
            }, null]
        }
    }
};

console.log(my);
console.log("omit null:", _.omitDeep(my, _.isNull));
console.log("omit undefined:", _.omitDeep(my, _.isUndefined));
