Culligan SY-2650 vs. Aquasana

[food4u]

How does the culligan SY-2650 compare to Aquasana? Does the Culligan SY-2650 accept standaard 10" replacement filters?

Culligan has discontinued the SY-2650 and has replaced it with the US-EZ-4.

You can review the US-EZ-4 here:

Pentek still makes the SY-2650 but sells it under their name. It is exactly the same as the SY-2650. Pentek calls it the US-1500. They system uses the same filters and comes with an electronic monitor to tell you when to change the filters. The system comes with a faucet and the installation tubing.

You can purchase the US-1500 at the following URL:

The replacement filters are the P-250A and can be found here:
http://www.waterfilters.net/culligan/undersink/replacement_filters/Pentek-P-250A.htm
These need to be replaced every 500 gallons or 6 months. The electronic monitor will monitor the water going through the system and alert you when they need to be changed. You can use any two filters in this system that are approximately 9.75" x 2.4" x 2.4".

The best drinking water systems are the Reverse Osmosis systems. I don't know if you've looked at those at all. The RO Systems are better than under sink systems because they have the reverse osmosis membrane that reduces dissolved solids. Regular under sink systems cannot reduce dissolved solids. Dissolved solids include nitrates, nitrites, barium, cadmium, sodium, etc. RO Systems are more expensive but they do reduce more from the water. All of our RO systems are located here if you would like to take a look at them:

Thanks for the info...

Short of the RO systems... would you say any system with a pre-filter and carbon block filter is the next best thing? Or is there a technology that is better? (again, besides RO)

How does the GE GXSV10 Under Sink Water Filter System compare to US-1500?
Aren't these simply "housings"...and it's actually the quality of the filter that makes the difference?

[waterfilters]

The US-1500 is the next best thing to the RO system. The filters reduce sediment, chlorine taste and odor, mercury, chemicals ( VOCs), pesticides and herbicides, MTBE, etc. These are really good filters, so I don't think you would want to use different filters in this system although you could.

We like the Pentek / Culligan systems better because it is easier to get replacements parts. The GE housings are harder to get replacement parts for (if they are even available).

For these types of housing, you are correct – the quality of the filter is what matters. The filters reduce the contaminants and sediment.
