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.

Replaced or a traditional undersink RO with this system and it seems to be the right choice. The ordering process was simple and receipt of the unit was very fast. I appreciate the fact that it doesn't waste nearly as much water at the traditional system not only because I live in the desert and that's anathema to my being, but also because I hated hearing that incessant trickle for 15 minutes while the traditional system balanced itself out.
