Undersink Reverse Osmosis - Kinetico or Home Master? (Scottsdale, Tempe: how much, house)

[SpaceNeedle]

We are looking for an undersink RO system. If you own one of these two systems, we'd love to hear about your experiences on the quality of the drinking water, the system, the services, or anything else that you'd like to share.

If anyone would like to recommend any other brands, we'd love to hear from you as well. Thank you so much.

I'm not sure if there's much difference between brands....when I google the topic they all seem to look very much the same ... a tank, 3 vertical filters, 1 horizontal filter across the top (usually). Our house was built with a line under the sink to feed the ice maker in the fridge and the R.O. systems have an output that feeds R.O. water to your ice maker. Most fridges have a water filter and with the R.O. system some people may be tempted to not use the filter in the fridge. We chose to use our fridge filter as well to get even more stuff out of the water.

I've never seen Consumer Reports rate these things so I take the seller's claims with a grain of salt about how well they work. I suspect the vast majority of these R.O. systems to all work about the same. Anyone selling one of these will tell you their's is the best (Oh sure, the check is in the mail! ... I paid cash for my Benz! I borrow at prime rate!). Brands on Amazon will probably state their specs but we've heard in the media lately that a given percentage of glowing reviews are bogus. Paying a lot more for a small incremental improvement in stated specs is probably not money well spent.

We have an R.O. unit put in by ProSkill who serve this far upper Peoria area. For an annual service fee they come by and replace the filters and also flush the crud from the water heater while they're here. We're full time, year-round residents and we use about 1 to 1.5 gallons of R.O. water every day.

One thing I did was buy was a TDS meter to check the amount of Total Dissolved Solids in our water. IIRC the EPA recommends keeping the PPM for TDS at 50 or below. My Peoria water comes out of the tap at about 475 PPM for TDS, probably calcium or lime, not sure. My R.O. filter outputs water at about 75 PPM and after the R.O. water goes through the filter in the refrigerator is comes out at 45PPM. These are about $20 on Amazon or other sites. When the PPM number starts rising for water from the refrigerator then I know it's time to change that filter.

I got 2 of these from amazon for me and my folks we love the way the water tastes and I also had it hooked up to my refrigerator for clean ice and water. It tastes much better than bottled water

Can't attest to their quality, but thought it was cool that they were headquartered in AZ.

I posted that one. To expand, they make a ton of parts for nearly all of the RO brands across the country. Meaning, most brands are just glorified kit builders using other people's parts. When buying an RO system, a large part of their longevity will be based on how much their replacement parts cost and can you acquire them later when they wear out. I ran into this exact problem with another RO company when the filters/membranes cost about the same to replace as buying a brand new system. Some of the kit builders manipulated their internal part number which makes it tougher to cross-reference it to a Premier part.

When I decided to add an RO system to my MN home, I just bought the Premier. If I was in the market for one in AZ again, I would call them to see if they have an outlet onsite.

Interestingly enough, one of the OPs brands of RO was "Home Master". A quick google shows them to be located at:
Perfect Water Technologies, Inc.
7701 E Gray Rd, Ste 109
Scottsdale, AZ 85260

The owner has a few patents so they at least are more than a kit builder. To the OP. Stay away from the cheap black flip-style handles. They gurgle when they are producing the water. Plus, they break and are cheap looking.
