1. If you are not an expert in industrial filtration, we strongly recommend you to choose a big professional company. Normally, big company has full process from sample development to final order fulfillment. In case you are not smart in this, they can assist you and get you the suitable products for you. And normally, bigger companies will do honest business. However, if you are an expert in this, you can source some good small factories, they may lack in customer service, and whole order process, but they can provide the lowest price. But if you know how to make requirements, they will surely do according to your requirements, too. In my opinion, choose a reliable partner is quite important, from my decades of international business, clients never change suppliers, even though sometimes, the supplier increase prices due to some reasons, they will still work with you. Unless your products have quality issues, but if this happens, even if you provide great compensation, they will not trust you anymore.
