It’s not really “annual” in my opinion

I probably change my filter once every 2 weeks. And the yellow stick probably needs changed every 2 months as last time I went just past 3 months, I had some algae like stuff building up on the walls.


Thanks for your feedback. Sorry you're not 100% happy with the product. I have issued you a gift card towards your next Annual Maintenance Package!!

Great company!

Great product really works. I wish we had known about the extra filterration products as they are really effective.

Donald Proctor (West Palm Beach, US)

Last one only lasted 1 week before I had to replace due to lack of flow and not chilling properly. Sponges don’t seem to work and I don’t know if algae treatment is working or not


Thanks for your review. If your filters are only lasting 1 week, there is likely some kind of a problem. Give us a call at your convenience so we can troubleshoot and see what might be the cause. Also, if you do have a salt based water softening system, you will likely need to bypass the water softener when filling up your tank as the water softened water can cause problems with filters.

Either way, we only want happy customers, so I have issued a full refund for the item you purchased.

Again, please reach out at your convenience so we can see if there's any troubleshooting needed: 714-509-1320. That's my direct line. If I miss you, just leave a voicemail and I'll get back to you ASAP.
