Opt for high-quality materials, such as silicone or phthalate-free plastic, and ensure that the pump fits your size. Make sure the pump can create a vacuum pressure suitable for your needs. Take into account any additional features that might be useful to you. Determine the purpose of using the pump. Finally, follow the usage instructions and consult a healthcare professional in case of underlying health issues.
