Do *NOT* Buy Until You Read This Hahn vs Aquasana Comparison

Article Last Updated: November 2021

Before talking about Hahn vs Aquasana let’s take look at why you might want to get one in the first place.

Water is vital and absolutely essential. Our body is roughly 65% water and can only work with a proper amount of water and minerals.

The water we drink, shower and cook can have a significant impact on our health.

Hahn drinking water filters claim to use the best filtration technology and so do Aquasana.

Yet they will also re-mineralize which means it adds back healthy minerals back into the water. This includes potassium, magnesium and calcium.

The result is a healthy and tasty water that gives the body optimal hydration.

All of these claims come with independent testing and certification. This includes NSF certification and other independent testing.

Both brands also make big claims related to the environmental impact of their filters, which are made from recyclable parts and compostable materials.

Now that we are familiar with some of the big similarities, let’s look at how they are different. This will help us find out which one is better.

  1. I also have the Hahn RO system i got 6-7 years ago. I can’t seem to purchase replacement filters anymore, not sure if Hahn stopped selling. My question is simple… can I use Aquasana replacement filters in my current Hahn RO system?

  2. I currently have a Hahn reverse osmosis system and the replacement filters are very expensive. They are no longer offered through Costco. Would you be willing to dissect both sets of filters (hahns and aquasanas) to find out which system is the best? I see that you recommend aquasana, but what’s inside those filters and which ones are best? Since my Hahn system is over 6 years old, I would be willing to replace it if I knew the answer to this question.

    1. Hi Michele

      I have taken a quick look at both of their replacement filters and it appears to me that they are virtually identical. I would be willing to bet that both brands white lable certain products from the same manufacturer.

      The only difference that I can see is that Aquasana replacement filters are typically cheaper and have more cartridge options.

      Stay hydrated,
