+### Custom filters
+Also, you can use built-in custom filters. Or, you can create your own filter.

+[Example of custom filter](https://github.com/eternnoir/pyTelegramBotAPI/blob/master/examples/custom_filters.py)

+Also, we have examples on them. Check this links:

+You can check some built-in filters in source [code](https://github.com/eternnoir/pyTelegramBotAPI/blob/master/telebot/custom_filters.py)

+Example of [filtering by id](https://github.com/eternnoir/pyTelegramBotAPI/blob/master/examples/id_filter_example.py)

+Example of [filtering by text](https://github.com/eternnoir/pyTelegramBotAPI/blob/master/examples/text_filter_example.py)

+If you want to add some built-in filter, you are welcome to add it in custom_filters.py file.
+	
+Here is example of creating filter-class:
+	
+```python
+class IsAdmin(util.SimpleCustomFilter):
+    # Class will check whether the user is admin or creator in group or not
+    key='is_admin'
+    @staticmethod
+    def check(message: telebot.types.Message):
+        return bot.get_chat_member(message.chat.id,message.from_user.id).status in ['administrator','creator']
+	
+# To register filter, you need to use method add_custom_filter.
+bot.add_custom_filter(IsAdmin())
+	
+# Now, you can use it in handler.
+@bot.message_handler(is_admin=True)
+def admin_of_group(message):
+	bot.send_message(message.chat.id, 'You are admin of this group'!)
