Guide To Buy Best Water Filter For Salty Water

The only way to get rid of salt from water is by using filters. Water filters not only remove salt but also make water contaminants free. But how can you recognize a filter which is best for removing salt? 

Below are some factors that help you to pick a perfect water filter.

Reverse Osmosis

We recommend buying a water filter system that offers RO technology. In such a system, water is forced to pass through a semipermeable membrane; this membrane filters contaminants to 0.0001 microns. It only allows water molecules to pass through the filter; the salt and other pollutants stay. In this way, you will get pure and salt-free water.

NSF Certified Filters

Only NSF-certified filters are trustable as they offer high performance. Make sure your filter or pitcher is NSF certified. Compared to other filters, the NSF standards filter offers 5X better filtration and lasts longer. 


The last thing is price, and it varies from filter to filter. But the more you invest, the better value you will get. The $120-$200 range is best; in this range, you can buy an APEC filter system and iSpring system. 

And if you want a permanent solution, you have to make a serious investment in whole house water filters. For that, AFWFilters and Aqasana whole house water filters are the best solutions for salty water.

Final Words

Salty water may be dangerous for your health and heart, especially for the elderly. You should avoid such water. The only way to remove salt from water is by using water filters. The water filters, as mentioned earlier, are best for salty water, making your tap water cleaner and improving its taste. 

For a permanent solution, we recommend the APEC water filter as its top rate filter on our list. All other water filters also remove the salt, not it’s up to you which one you want to buy.
