Designed for easy DIY maintenance, the carbon and RO filters and optional remineralizer cartridge have a two-year lifespan so you can quickly and easily replace them at the same time, and it takes less than a minute to replace each filter. You can install with confidence, knowing the Delta® Clarifi™ Tankless Reverse Osmosis System is backed by our warranty and highly-trained, live customer support.

Review: We’ve had the Delta Clarifi installed for about 9 months now and it’s been a huge upgrade. We had a traditional RO system with a big bulky tank before. This one freed up a ton of space under our sink. I was honestly shocked by how much room we got back. The water tastes noticeably better. Clean, fresh, no chlorine or chemical aftertaste. It fills glasses quickly too, which I didn’t expect from a tankless system. It looks sleek, runs smoothly, and is certified to filter out all the stuff that matters like lead, chlorine, PFAS, and more. Filter replacements are simple and it reminds you when it’s time so there’s no guesswork. A couple quick tips. It does need power, so make sure you have an extra outlet available. Ours was taken up by the garbage disposal, so we installed a Garbage Disposal Wireless Switch Kit and now everything runs seamlessly. There’s also a short flush process during setup but it’s easy and well explained. After 9 months, still very happy. Great water, no bulky tank, and a cleaner, more usable cabinet.
Review: This replaced my old Aquasana RO filtration system that used a tank. This Delta one is far better in many ways and I’m really happy with my purchase. First the total cost of ownership is less, there is no tank so I can use lots of water for cooking and drinking all at once, the system tells me when to replace the filters, it wastes less water and the water comes out really fast and tastes good. Now to the noise. It’s not a problem AT ALL! I was concerned reading the reviews here that it was going to be really noisy when it was running but I can barely hear it in the under sink cabinet and the water landing in my glass is louder than the machine. There is a customer video here of it being really loud which was concerning but after doing my own install I can say as an engineer that if anyone is having a noise problem they either have a defective unit or didn’t install it correctly. If the machine is in spec and you install it correctly you won’t have a noise problem, simple as that. In order to ensure mine would be quiet I had to take some very specific steps - preloading all the water lines with water to ensure when first turning on the unit that no air was sucked in, ensuring no tubes touch the sides of the unit while it’s running by doing a clean and organized install, not using an air gap faucet (they aren’t needed for tankless systems like this unlike the old tank RO systems that do need the safety feature of an air gap), and finally using sorbothane vibration isolating feet on the unit instead of the factory feet which isolates vibrations from reverberating through the sink cabinet and making noise. If you do all of those, you’ll be set! (If you watch the video I attached you can hear the faint dull hum of the machine filtering in the background as the glass fills) (Photo is of sorbothane feet for vibration isolation)

*by P***N on 10 January 2026*

Works well so far (2 months ownership). It is loud as others have said in their reviews. I put foam blocks under the unit to abate some of the noise. Also note, placing the remineralizing cartridge on your system could potentially raise your pH level quite a bit. I ended up removing the cartridge to bring the pH level down.
