Under sink water filters are installed out of view and leave the counters available for use, which helps save space in any kitchen. In this article, I look at the 9 best under sink water filters for well water. I selected 3 designs that represent the best water filter price, treatment rate, and value for any budget.
The top 3 filters I selected operate on reverse osmosis. A water filtration process that uses pressure to send water through a semipermeable membrane at super-high rates which remove impurities and contaminants for clean, high-quality drinking water.
Really, what else could fit through those tiny micron-sized holes? Pure water for a healthy life.
Included is a comparison table where you can compare the key features and more, plus detailed reviews that provide critical features of each water filter, their price, etc. I’ll help to answer those questions as we look at the top 9 best under-the-sink water filters available:
Table of Contents
Why Should You Treat Well Water?
To be honest with you, I prefer well water over the city supply water at any time. It comes from the natural underground source, and usually, well water is rich in healthy minerals.
This being said, underground water just tastes better on most occasions.
However, as much as I like well water, it is far away from being safe these days too.
Just think about it for a second.
As humans, we release so much waste to landfill daily. It has all sorts of different forms:
- Industrial runoffs (chemicals, synthetic materials, industrial oil)
- Agricultural waste (pesticides, herbicides)
- Urban runoffs (flooding, communal runoffs, pharmaceutical)
- Commercial runoffs (cleaning chemicals etc.)
And this is just a small example.
Now, the layer of the ground that separates water and these runoffs works as a filtration medium.
It absorbs these runoffs, and they pass through the layer to the point when they eventually reach water under the ground.
The truth is, that ground player works well as filter and absorbs a certain amount of contaminants. However, a lot of pollutants still get into the water.
Generally, the deeper the groundwater source is, the fewer contaminants are likely to be there, but with the populational and economic growth, it is almost impossible to find a pure and clear water source.
I am not saying that they ‘don’t exist, but compared with the past, the number of sources is way smaller.
Regardless of the depth of ground source, well water always will have sediment present in it which needs to be removed too.
For the reasons mentioned above, I believe that well water must be treated as any other source.
In the following section, I have selected my top ten picks.
Before you jump onto them, I just wanted to add that I well water is usually hard because of all the minerals. This is the reason why I have selected quite a few reverse osmosis products here.
How do the Top 9 Look?
‘Here’s where you can read about the under the sink water filters that I recommend in more depth. Find out which filters best remove contaminants, how long they last, and more.

iSpring 6-Stage RO – for the special Editor´s Choice award, the iSpring wins for overall value, and not just because the filter is transparent purple! The 6-stage process with alkaline remineralization is a pro-feature of this filter for clean drinking water right out of your kitchen faucet, with superior water to bottled right at home.
You can taste the difference. It has a cool design, includes the Alkaline Filter for remineralization which adds nutrients back into the water, restores pH levels, and offers reverse osmosis at a fine price point.
Final Words
That’s all for this review, and there are more than a handful of candidates looking good. I hope you feel you learned something and go on to upgrade to clean, pure water (at least 99%) with a better water filtration system for your home and office.
At the end of the day, it’s all about quality and finding the right system that works for you, paired with the best purity rate for an all-star home run. If this review helped you, and you have an idea or question to add to the discussion, please feel free to send in your comment, and get in touch.
I look forward to hearing about your experiences with whatever filter you choose. Good luck!
Really detailed information. I am considering buying a water filter at the moment as the normal tap water always has a chlorine taste to it. As a family we started buying bottled water but it works out too expensive over time.
I am definitely interested in switching to a water filter long term.
Thanks again for info.

Hi Mark,
Yes bottled water is a very expensive solution but also not very healthy one, as plastic contains a lot of chemicals in it as well. I am preparing an article on this topic. I am glad that you have found this article helpful.

Your page is very detailed. I’m not ready to purchase but the information you provide will help me make a decision in the near future.
I am quite familiar with the water filter business as i deliver leaflets for a company based in Woking, England. You have covered quite a selection here and they are all great models to choose from. I will check out the price range to see what is the best offer and see how they compare.
Hello, I have a question, I live in Mexico and the water is not safe to drink out of the tap. Will using one of these make it suitable to drink?
Hello Joseph, Yes these will make your water suitable to drink. Hope, you have selected the best one for your needs 🙂
It would be very helpful if you would rate the best non-reverse osmosis under-sink filters. The wastewater could be an issue for some of us with septic tanks. As much as I want reverse osmosis, I don’t think that it would be an option for us – unless there is an RO system with very little wastewater.
Have you ever rated Mountain Pure or Waterstone?
Also, would your ranking in the article be the same for non-well water? ( Ex., we are on city water.)
