Bought on MyWaterClub.com
MWC-5DT-1-100 or MWC-5DT-1-150
All of these models use the same replacement filters. They differ in the diverter, the adapters included and the size of the RO membrane. Your model and membrane size (75, 100 or 150 GPD) are marked on the sticker under your unit.
Replacement filters
Your system needs new filters every 12 months and a new RO membrane every 24 months. Filter life varies with your water quality and how much water you use.
Every 12 months
Annual filter set
4 filters: sediment, T28 carbon, DI mixed bed and T33 carbon. The RO membrane is not included.
Every 24 months
Filters plus a new RO membrane
On Amazon the membrane is sold separately: order it together with the annual filter set. On MyWaterClub.com the complete set includes the 4 filters and the membrane. Choose the membrane size your system uses now.

Which set do I need this time?
Year 1: annual filter set. Year 2: filters plus a new membrane. Then repeat. The date you wrote on the sticker under your unit shows when the filters were last changed.
How to replace the filters and the membrane
The filter guide shows all 27 steps with photos. Plan for 35 to 50 minutes. The membrane guide is a separate, shorter guide.
- You need the new filters, pliers and paper towels. For the membrane you also need a membrane wrench.
- A collet tool makes the tubing easier to release. It is recommended but not required.
- Before you start, take photos of your system from both sides, so that the flow arrows on the filter labels are visible.
- After the change, check for leaks and flush the system for 20 to 30 minutes before drinking the water.
- Not sure it is assembled correctly? Text photos of your system to (858) 345-7345 and we will check them.
