Frequently asked questions

What does the TF-4113 sediment filter remove?
It removes larger suspended particles such as sand, dirt, rust, and silt that can affect water clarity and system performance.

Will TF-4113 fit my ISOTwist?
Yes, it's the OEM sediment for ISO-450R / ISO-550R and appears in their filter kits. 

How often should I replace it?
Vertex/retail guidance: about every 12 months (sooner on turbid water).

What does 5 micron mean?
It indicates the nominal pore size, great for sand, silt, and rust protection ahead of GAC/carbon block and the RO membrane.

Does this filter improve taste or odor?
The sediment filter focuses on particulate removal. Taste and odor improvement is handled by downstream carbon or specialty filters.

Is this filter reusable or washable?
No. The TF-4113 sediment filter is disposable and should be replaced when it reaches the end of its service life.
