How long do under-sink water filters last?
Most water filters need to be changed every 6 months or 1 year. Our sediment and carbon filters should be replaced every six months. You will only need a new post-carbon inline polishing filter once a year. Finally, if you have a reverse osmosis membrane that lasts 3 to 5 years. However, high-demand situations or well water may require more frequent changes.
The 1-year water filter supply for a standard four or five-stage unit includes:
- 2 – 5-micron sediment filters
- 4 – 5- micron carbon filters
- 1 – post-carbon inline polishing filter
- Optional reverse osmosis membrane (additional charge)
- 1 filter housing wrench
What type of replacement water filter do I need?
Most water filtration systems use standard-sized filters, but some systems use proprietary filters that can only be purchased from the manufacturer. If you are unsure what replacement water filter you need, consult your water filtration system manual or contact us. Be sure to include the manufacturer and the model.
