FAQ

Topway Global Frequently Asked Questions

How do I order replacement filters for my Topway Global RO drinking water filtration system?

Start by clicking on the photo of your Topway Global (TGI) RO system above. From there, you can add the needed filters to your cart. In some cases, you can save time by ordering all of the needed filters in one "filter kit" (not available for all models). Keep in mind that the RO membrane usually only needs to be replaced every two years, while the sediment and carbon filters are replaced every 6-12 months depending on water usage and water quality.

Which Topway Global (TGI) RO membrane and filters do I need for my RO system?

Although Topway Global (TGI) no longer manufactures RO systems, we still carry replacement parts for these systems. Select your RO system from the list above. You will be taken to a new page that shows the available membrane and filters for your RO system. Be sure to select the correct membrane size (listed in GPD or gallons per day). If you have any questions, please call our customer support team at 1 (877) 377-9876. We're available Monday through Friday, 9 am to 5 pm Central Time.
