Countertop VS Under Sink Water Filter System, Which is Better?

Last Updated on

There are mainly two types of drinking water filter in the market, countertop and underSink water filter system. The usual question that was asked is which system is better?

In my opinion, it is all depends on the functionality of the system..

No matter it is a countertop or a under sink water filter system, the functionality makes it stand out from it’s competitor. However, there are still some major difference between the two. Let’s check it out.

Counter Top Water Filters are not always that affordable…

Although most of the systems in countertop water filters are simple and inexpensive, there are some systems such as the ionized alkaline system and the countertop reverse osmosis system can compete with the comprehensive under sink water filter system.

Countertop ionized alkaline system can be very expensive. Kangen is the most popular brands for counter top ionized alkaline water system. However, it cost more than $3000 to own a Kangen Ionized water system.

The main reason for the high price tag is due to the sales comes from multi-level marketing. The sales person pockets a huge portion of the profit for every sales that is made. Despite the overpriced water ionizer, there are still some affordable ones in the market.

  1. Wow plenty of very useful information here and quite a choice to make.
    Like the way in which you have given the pro’s and con’s of the various installations which of course allows your readers to make an informed decision.
    We have just had a water softener installed. Changed the taste of the water. Do the water purifiers do the same thing ? And my other question is whether the table-top purifier really does do it’s job or is it the poor cousin to those that are installed.
    A great and very informative article which was very professionally set out.


    • It depends on the which type of counter top water filter. The APEC reverse osmosis counter top water filter does a great job in filtering contaminants just like the undersink water filters. My personal opinion, go for the under sink water filter system as they are more choices the solution is more comprehensive.

  2. Wow, Jay, this article is so informative. Take it from me, some one who knows NOTHING about water filters! Now I feel that I could make an informed decision, just by reading this one particular post! Thanks for sharing your knowledge where this is concerned!

  3. Lots of information here Jay, I remember when I used to live at home… my parents had the counter top system. I never really thought of it and how necessary it is until I read your post. To be honest, I use Brita filters in my Brita Jug. I know these systems are obviously more advanced, but how does Brita filter compare? Just curious.

  4. Love the information. My question is I have a RO system through Culligan that is maintained through them. I have bradenton fla county water and have purchased a Aqua ionizer deluxe 7.0. So the question is do I hook the ionizer to the ro water or do I delete the ro system and just use the ionizer. Thanks in advance for your knowledge. Michael Gurucharri MD

    • Hi Michael, Great question. It depends on how contaminated is your source water.
      Aqua Ionizer Deluxe 7.0 comes with an activated carbon filter and the ionizer. It is more suitable for city/municipal treated water which mainly reducing chlorine, odor and taste from the water. In this case, you can just install the ionizer and remove the RO system.
      If you are using well water source, my advice to you is to keep the RO system to get rid of various contaminants before going into the ionizer. This will make sure that your water is clean to consume and the Ionizer will help on adjusting the pH of your filtered water.

      Hope this helps 🙂


  5. 1-Under the sink ionizwr , as you say removes 99% of contaminants ; what porcentage will be removed with over the counter ionizer.
    2- which one is better : ionizer or reverse osmosis on a city water?
    Thank you

    • Hi Jorge, I think you meant under the sink filter instead of ionizer. As far as I know, there is no under sink ionizer. Regarding contaminants removal, it is actually based on which filtration system that you are referring to. If you are referring to reverse osmosis filter(No matter it is counter top or under sink), it removes 99% of the contaminants.
      Some of the countertop filters only remove certain contaminants such as chlorine, mercury, lead, fluoride etc. You can refer to this guide on the countertop water filter.

      For your second question, ionizer is basically changing the pH using electrolysis. It comes with a pre-filter which remove basic contaminants. If you want the cleanest filtration system, go for the under sink reverse osmosis system.

      Hope this helps.
