"this is a good uv sterilizer. I got this because of the water flow sensor. I just wish they had a delay when turning off instead of instant off. often times i have to fill a couple glasses of water, so after each fill, the uv turns off and then on for the next glass. a 5-10 second delay on turning off would be great on the bulb."

We installed on our refrigerator. No problems, took about half an hour. The filter is very well made and comes with a Phillips light. I would recommend. The only thing we had to purchase was extra tubing. We are happy with this product.sivic

This is an excellent UV filter and the customer service is very personable.After several months, the light stopped turning off after use and it was overheating. I called the company and Sean generously offered to replace the entire unit. I have since added a surge protector to the socket in case surges were the cause of the malfunction.Thank you!larry

Solid little unit, this is the final piece of what I need for the purest water possible after my RO. I've had it for a few months now and I've noticed that my water bottles don't get musty if I have water in them for a couple of days.Sean was particularly helpful when I called to answer any questions I had for use and maintenance as well as questions to upgrade to a whole house filteramanda perye

I've had this installed for a few months and my cat and myself notice a nice improvement when added to the existing system. The value is great for what it is. So far I've not had any issues. The bulbs work great after daily use. There's no odor to the water and doesn't affect flow. Decent product I would recommend to anyone wanting a little better quality water.What Customers Talk About
