Nope! While many manual nectar collectors (or nectar collectors without electrical components) may use water filtration, many do not. If you are using a nectar collector-style wax pen, you will almost never find water filtration being used. Many users are hesitant to use a nectar collector with water since they involve so much movement during the dabbing process. You will have a choice in which style works best for you, so be sure you understand your specific needs before you pull the trigger and buy a product!
