Members or distributors also have multiple inventories unsold in their homes or private shops. This is why NSA filtering units remain available for sale in many locations and even online.

Installing an NSA 50C
The NSA 50C screws to your faucet through the spout. Note that older models have short spouts. Your kitchen faucet should have a thread at the tip.
Sometimes, these units come with a strainer. If yours does, you will want to unscrew it first. Then, install the NSA 50C valve that comes with your purchased kit. You may place back the strainer after you’ve completed screwing the valve one.
Finally, connect the quick connect hose using the specific nut and compression sleeve. You will then have to lightly tighten the connection with some pliers. After that, your filter is ready for use.
At times you may need to throw out the first few filtered cups of sink water. So do this especially if there are some black particles that have come loose from the granular activated carbon and silver filter.
How Long Do NSA 100S and 50C Units Last?
NSA filter system units are disposable. Each filter is fitted with granular activated carbon and silver, which serves to inhibit bacteria growth. Hence, it has a limited life. Further, the sink filter will degrade and it will consequently fail to absorb contaminants after it reaches its maximum use.
Here are some indicators for when it’s time for a new replacement filter:
- When the water quality is no longer as fresh-tasting and clear
- Once its water flow becomes limited or when it slows down
- Next, After you’ve used the sink filter for a maximum of two years
- If one has used it for 6 months to 1 year in a highly contaminated water area, and lastly,
- As soon as you’ve reached the filter maximum life of 3 years
We should also mention that NSA 50c filter is a completely sealed filtration device. There is no cartridge to replace. Hence, it is wholly disposable.
Why Does the Length of Use Vary Among NSA 50C Users?
The length of use varies with each household and location. Generally, one NSA 50C filter may last anywhere from 3 months to 3 years. Some sink water filter owners even reported being able to use this filtration device for 5 years. So what affects the length of use?
- Number of users in a household
- Quality of water in your area, and
- Frequency and volume of filtration
Does NSA 50C Filters Take out Fluoride?
Yes. Plain carbon filters may be inefficient in filtering out fluoride. But the NSA 50C filter uses granular activated carbon to clear your water of contaminants. And this includes filtering out fluoride in tap water.
Do the Connectors Come With the NSA 50 C?
Yes. Your purchase will include the accompanying quick connect hose. Users say the filter material is thick and durable, so it should last you a long while before you’d need to replace it. However, note that during initial use or at the installation of this filter, you may need to wipe it down. Do this first in order to remove the protective oil around it.
Does This Filter Have Available Replacements?
The NSA 50C quick-connect filter is a discontinued product. But an abundance of units remains available for sale. It is a disposable product since it is a sealed filtering device. So once you’ve used the filter to its maximum capacity, you need to buy a new unit to replace it.
Besides buying the same model as a replacement, you can also move up to an NSA 100S. USA Filtration also makes an available replacement for NSA 100S. The Water Marque filter for NSA 100S is also an option. Lastly, you may check replacement units from H20 Distributors. These NSA 100S replacement units and NSA 50C are all available for purchase online.
NSA filters 50C and NSA 100S have maintained a loyal customer base despite being discontinued for production. Units still sell online. And users give positive reviews on granular activated carbon efficiency in removing contaminants like chlorine, fluoride, bacteria growth, and filters other sediments from household tap water.
