They are the same company! Filters for Aquasana fit Hahn water systems!

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?

In reply to Michele. 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, Luke

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.
