Description
3 Filter Replacement Set for 4-Stage Basic MyAquaFilter Countertop Reverse Osmosis (RO) Systems, including 5-micron Sediment, T28 carbon, and T33 post-carbon inline filters.
Compatibility: Compatible with most 4-stage portable and countertop RO purification systems.
Set includes 3 filters:
- 1st Stage – Sediment Filter: Premium Quick-Connect 5-micron sediment filter. Captures dust, dirt, sand, and rust particles while helping extend the life of the RO membrane and the entire system.
- 2nd Stage – Carbon Pre-Filter: Premium USA-made Quick-Connect T28 coconut shell activated carbon filter.
- 3rd Stage – RO Membrane: Not included.
- 4th Stage – Post Carbon Filter: Premium Quick-Connect T33 coconut shell activated carbon filter for taste and odor improvement.
You can choose one of the following options:
- Filter set: Replacement time approximately 30–40 minutes. Difficulty level: moderate.
- Complete Assembly: Includes replacement filter set, fittings, clips, new RO membrane, and membrane housing. Allows replacement of the entire assembly in about 1 minute. Only two tubes need to be reconnected (from the kitchen diverter to the assembly). Difficulty level: easy.
Sample assembly images shown for 4-, 5-, and 6-stage countertop RO systems. Actual assembly may vary depending on the filter configuration.
