Review: Top notch filter system - Top line filter system that purifies the water very well it's easy to use and makes the water not only pure to drink but also taste very good, I did have some problems after the first filter change but a call to Robert at iSpring took care of the problem right away the same day, if you are looking for a top notch filter system and good American based customer support this is the system or other iSpring systems are some of the very best with great customer service, and thank you for the help and great customer service
Review: Great Customer Service - I purchased the iSpring RO5004F-AK about six months ago. Shortly after installing it, the unit began beeping because of an issue with the UV system. I contacted iSpring and spoke with Laurence, who was extremely helpful and explained how to reset the unit. That resolved the problem. Six months later, a similar issue occurred, but this time the lights were flashing and the beeping would not stop. I contacted Laurence again, and he immediately sent me a brand-new head unit—essentially a new RO5004F-AK, minus the filter cartridges. The replacement completely fixed the issue, and the system now runs even better than before. It is rare these days to find a company that responds so quickly and truly stands behind its products without giving customers the runaround. iSpring’s customer service has been outstanding. Thank you, Laurence!

### ⭐ Problem Filter
*by D***Y on October 25, 2025*

UPDATE: 1/24 - replacement unit failed within 3 days of install. Do not waste time or money with this product. There is a serious manufacturing and qc issue. UPDATE: 11/6 - customer service has shipped a new unit and is pending installation. I appreciate the response and will update the review once the new unit has been installed and tested. It’s been nothing but problem after problem with this filter. Within 1 week of installing it the filter started beeping non-stop. Contacted customer service and they said it just needed to be reset. I reset it. A week later same thing happens. I contact them and they say a part needs to be warrantied and they will send me one. I wait a week nothing, I contact them no response. Another week nothing. It has been close to 3 months now and you can’t even use the filter because it doesn’t flow properly and constantly beeps. No response from customer service and a $500 product that doesn’t work. Maybe this review will get their attention. Very disappointed.
