NSA 100us Under Sink KDF/GAC Water Filter (Compression)

Replacement for a NSA is Water Marque. NSA extinct. Not a lot of choices, but specs appeared to be the same. Fitting sizes are different than original NSA, but replacement fittings are in package. All seems to be good. No leaks, etc. I must say the water taste much better.(residence is close to water plant--high chlorine or chemical taste in water). All good! All clear! Better than bottled water.

I love this product and have used one on my kitchen sink for the last 25 years. Sadly - this type of NSA filter is no longer being made. I was SO happy to find one from second level distributor through Amazon. They last 3 years. When this one wears out - I will have to make a change and nothing seems to stack up against this unit.

I love this water filter. Ordered it before through a different party but this time it came very quickly. Ordered it on Thursday and we had it the following Wednesday and had it installed immediately by my brother in about 10 mins. LOVE IT. It lasts about 18 months and our water it so good and clean.

This filter was the recommended replacement for my old NSA filter, and it was easy to install using the same connections. The water tastes great!

It was just installed so we will have to wait and see how it preforms. So far it seems to be filtering the water.

bought it from another recommendation from another buyer because of long life of filter and quality of water at tap.

Great filter...we wanted something hidden and not on top of the faucet. It was easy to install and the water taste great! I asked the company for a list of everything it filters out....very pleased with this product.

I ended up not needing the fiter. The merchant took it back without a complaint but did first try to see if there was any way I could have used it. Good communication.
