The water that reaches our home goes through a lot of treatment, which infuses it with a lot of chemicals. These chemicals, when ingested in large quantities, can cause serious damage to our body. For this reason, we are going to feature our top three picks when it comes to the best under sink water filter.

Water is one of the most important things you need in this world in order to survive. You need it for cooking, for drinking, for survival. Having quality water to drink out of the faucet is a worthwhile investment that every home needs to make. How about you? Have you invested in a safe and trustworthy water filtration system yet?

The Need for a Water Filtration System at Home

Observe what happens to your faucet after frequent use. It will require cleaning, later on, to save it from the metals that have collected through time. There’s even a possibility for these hardened sediments to reach a point of permanent damage that can lead you to replace your faucet altogether.

It is a sad reality that we have to install a water filter just to get safe and healthy water from our sink. So, how do you prevent these harmful materials from mixing with your drinking water? Do you really need to purchase separate water for drinking? Or is there a way to cleanse your water at home for drinking?

Well, that’s exactly what we are going to talk about today!

Top Pick #3: Aquasana Three-Stage Under Sink Water Filter System

Aquasana 3-Stage Under Sink Water Filter System with Brushed Nickel Faucet

CHECK LATEST PRICE ON AMAZON.COM

Finally, we have the Aquasana Three-Stage Under Sink Water Filter System as our third and final pick. This water filter system is quite different from the previous two we have mentioned because of two reasons:

  1. It has three separate tanks; and
  2. It comes with its own faucet.

Its capacity is also smaller compared to the first two as it can only handle 600 gallons of water. Don’t underestimate it only because of its capacity though, because the Aquasana actually has a powerful water filtration system that can match other powerful filtration systems out there.

Its first tank is a pre-filter, which takes care of all the sediments and rust in the water. The second tank is an activated carbon tank, which takes care of all the harmful chemicals present in the water. And finally, the third tank is a catalytic carbon tank, which significantly reduces the heavy metals present in the water for further disinfection.

For more information about this product, here is a quick list of its pros and cons:

The Pros:

  • Easy to install
  • Allows easy filter replacement
  • Has a faster flow rate
  • Comes with an alert device that tells you when it’s time to replace the filters

The Cons:

  • Can only be used for six months
  • Comes with a separate faucet that some users deem inconvenient
  • Comes with three filter tanks that will all need replacement and maintenance

The Verdict

So, after going through the top three under sink water filter systems, which one do you think is the best? Well, it actually depends on your priorities. What do we mean?

In terms of longevity and capacity, we definitely recommend the CuZn UC-200 Under Counter Water Filter. That 50,000-gallon capacity is priceless as compared to the measly 600-gallon capacity of the Aquasana Water Filter System.

If you really value the quality of water, though, not only in terms of filtration but also for its taste and odor, then we definitely recommend the Woder Under Sink Filter Premium Class. It only offers a fifth of the CuZn’s capacity at only 10,000 gallons, but the quality of water produced is significantly better than the previous filter.

Finally, some people prefer the Aquasana Three-Stage Under Sink Water Filter System since they feel that the three tanks are a lot more reliable than a single tank. The filters on these tanks are really easy and affordable to replace, after all.

In the end, it’s all up to you which one you prefer. Just keep in mind that when it comes to water, the most important thing is trust. You need to trust your water filtration system and trust the water you consume. If you do, then you’ll feel the quality of your life significantly improving, along with your health.
