The Taste Is Gone

The water with the Nu Aqua System was delicious when we first bought it, but after the first filter replacement it never returned! I have called Nu Aqua several times and no satisfactory answer was given. I even hired a professional plumber to install the filters and replaced all three at the same time. Same result.

When you call, you are told to read the manual. Very disappointing. I would not buy this system again.

Filter 1 replacement

Filter 1 lasted about 6 months in tankless RO system. Replacement was easy, and instructions were clear. Couldn’t order a replacement immediately because company took a holiday weekend for Memorial Day. Also, there was no description estimating free shipment delivery time, so had to pay for UPS second day. And there was no mention of how to recycle or dispose of the old filter or whether it could be returned to recondition. Double boxing was likewise not environmentally conscious.
