I opted for the Sedna water filtration system upon a friend’s recommendation. And I am happy that I did. It has made my life so much easier. I have the assurance that my family is drinking clean, safe water. I no longer have to deal with the stubborn marks that hard water leaves on various surfaces, and I am not cutting the lifespan of my appliances short by exposing them to mineral/chemical-packed water. What more does one want?
