...out of of probaly 24 or 30 filters, I have two filter not work, including one that increased the PPM over my tap water. When it works, it does work well.
We have 2 ZeroWater filters in the house for our very hard tap water. Bigger-quantity overpacks cost more up front but lower the per-filter price and economize on shipping.
Zero Water filters are the best! Website is easy to navigate, products are quality, shipping is great. I only drink water filtered by Zero Water filters and have for decades. The 5-Stage filters are a must for me and my family.
Filters are fine but my problem is with the testers that they send with the unit they do not work I’ve called had them replaced and they still do not work I complained and then they sent me one they won’t even turn on and laughed at me. Now I have to guess when to replace the filters.

We apologize for the issue with your meter, this certainly is not the norm for our testing devices. A new meter has been ordered for you and we appreciate your feedback.
