Can this product really keep foreign particles out of the mouthpiece, are they easy to clean and replace?
Imran Hanafiah –
Thank you for your question, Maribel! The Problue AC-89-3 Safe Plug for Mouthpiece is designed to prevent foreign particles from entering the mouthpiece, ensuring a cleaner and safer experience. The plug is typically made of a soft, flexible material that effectively seals the mouthpiece. As for cleaning and replacement, it’s usually a simple process. You can wash the plug with soap and water, and then let it air dry. In case of replacement, you can easily remove the old plug and insert the new one. We recommend using the same plug for the same mouthpiece model for optimal results. Please let us know if you have any further questions or concerns!

Faren Tan –
Took a week to arrive in Malaysia. The safe plug is really useful for traveling but it makes the mouthpiece a bit hard to clean due to the compact nature of the plug.
Zara Wong –
What’s the difference between this kind of safe plug and other ones in the market?
Imran Hanafiah –
Thank you for reaching out to us about your question, Zara. The Problue AC-89-3 Safe Plug is designed to be a more secure and reliable alternative to other mouthpiece plugs on the market. One key difference is that our plug features a unique ergonomic design that ensures a comfortable fit in the mouthpiece, making it easier to use and reducing the risk of dislodging. Additionally, the AC-89-3 plug is made from a durable, BPA-free material that resists corrosion and withstands high temperatures. This means our plug is not only effective but also long-lasting and safe to use. We believe these features make our Safe Plug a standout product in the market.
Joanna Foo –
Overall, I’ve been really happy with the safe plug. The one minor problem I experience is that the rubber grips don have very good friction which can cause me to accidentally lose grip when handling the plug. A small annoyance but a great product overall.
Alexis Abdul Rahman –
My favorite thing about the safe plug is how easy it is to install and remove from the mouthpiece. I do wish it were a slightly larger size, though.
Kathleen Tan –
To be honest, it’s easy to use and does what it’s supposed to do. Although, I’m not entirely sure about its durability
