Good deal, saves me from having to keep picking these up every 6-months to a year. These filters seem to do the job well, though I have not tested how effective the pH filter is under continuous use.

After about 13 months of use with my NON-iSpring 6-stage RO system installed last year by a local vendor, the water taste had noticeably changed. By then, Id been trying to schedule for weeks a date/time with the same vendor for filter replacement. When the tech finally came, he didnt have the alkaline filter with him... I said goodbye to him, and onto Amazon I went.These filters fit perfectly with my RO system. This is by far the best bargain for RO filters, and even includes a replacement membrane (replaced every 3 years). The local RO shop charges ~$150 to replace the 6-stage filters annually (not the membrane), and thats with the "6 months" filters being used for 12 months, and since iSprings includes 6 of the "6 months" filters, its an even better value. And you can replace the filters at your own convenience.Only caveat was I had to call iSpring to request 4 free quick-fit adapters to thread onto the stage 5 & 6 filters (my previous ones had quick-fit built into the filter cases), with several wraps of Mr. Gasket 2842G Teflon Tape. Phone support was very prompt and helpful.Check YouTube for simple "RO filter replacement" videos. Youll want to clean the Stage 1-3 filter canisters (the big vertical ones), since they get grimy after a year.If you dont already have a horizontal mount for the stage 5 or 6 filters, Id recommend S5-TO-S6 RO Kit for 2.5" diameter Inline Filter (buy 2 if you need a pair for both filters), which will keep the stage 5 & 6 filters stable and less prone to hose leakage.

Great tasting water and fraction of what the local vendors charge!

Purchased 3 year pack for 6 Stage filter which has better value. Purchased directly from 123filter.com. Quick shipping and excellent service support. Trust this brand and people. Will definitely recommend to any one who is interested in quality water and reasonable price.
