Rated 5 out of 5 by from Great and easy to install! I love that this can be used under the kitchen sink or a normal faucet. It was easy to install as someone who has changed shower heads before and is more handy with other parts of the house. It took more time clearing out a spot for it than to install it and I love having filtered water to fill up my pots for cooking now.

Rated 4 out of 5 by from Great investment but difficult to install alone. So happy to have recieved this! Makes me feel alot better about using our tap water. Most people would put it in the kitchen, but i use the bathroom sink ALOT and plan on adding another in the kitchen later on. One down side is if we wasn't having a remodel being done when I recieved this item, there would be no way I could of installed it. Alot more difficult than I expected it to be. So plan on bringing in someone to help lol.

Rated 5 out of 5 by from Higher water quality in a very small package The first thing you’ll notice when you pull the filter out of the box is how compact it is compared to some other bulky units I’ve used. Install is very simple just disconnect your cold line and use the included lines that just plug into the filter head unit. I have pretty bad tasting water this filtered the water to a drinkable taste and took away any odor. Mounting is easy the head unit has to holes you just slip over two screws .

Rated 5 out of 5 by from Clean water Super easy install and doesn't take up much space. I like that this hooks right up under the sink and you don't have to have a separate area with a tank or separate faucet. It's super efficient, super quiet and I like that I no longer have to worry about the quality of the eater coming from my kitchen faucet. Maintenance looks to be easy as there's not many pieces to assemble or take apart. So far so good no issues.

Rated 5 out of 5 by from Love!! Love love love this! We installed this and our water is so much better. My husband installed this under my bathroom sink. Super tight fit because of how small the area is but I love!

Rated 5 out of 5 by from Awesome I received the Delta Clarifi High Flow High Capacity Under Sink Water Filtration System free for my honest review. I needed this! It’s awesome. My husband just recently had to replace our faucet because it was leaking and now we have a new filtration system. I’m very picky about my water, especially since our home is older with older pipes. It’s good to have that filtration so I feel safe with my water. I feel so much better knowing I have this now. I love how simple it is to install and how it fits under the sink. The filtration system is made really well and feels very durable. I’m really happy with it.

Q&A

FREQUENTLY ASKED QUESTIONS

How should I decide which filter system to use?

Choosing the right water filter depends on your specific needs, water quality, budget, and installation preferences. Our two-stage system requires a dedicated beverage faucet and filters more contaminants, while the single stage system connects directly to your existing faucet with minimal effort.

Start by identifying the contaminants in your water. Check your local water utility’s Consumer Confidence Report (CCR) using our Water Quality Look-Up Tool or test your water with a DIY kit or professional service. Choose a filter that fits your installation needs and is certified to remove the contaminants you’re targeting.

Under-sink filters strike a balance of convenience, effectiveness and affordability for most households, especially if your focus is cleaner drinking and cooking water.

Is the filter system hard to install?

The Clarifi system is designed for simple, DIY installation and comes with detailed instructions through the user guide and installation videos. However, the difficulty can depend on your DIY skills, tools and existing plumbing setup.

Tools You Might Need:

  • Screwdriver
  • Drill
  • Teflon tape (for threaded connections)

Note that this system can only be installed to a cold-water line. Running hot water through the system will cause damage.

What do I need to know about replacing the filter cartridges?

The filters will need to be replaced about every 1 year or after it’s filtered 10,000 gallons, whichever comes first. The system will use audible alerts and the LCD digital display to notify you when it’s time to replace the filter.

You can order the replacement filter through our website or other vendors. Other brand filters are not compatible with the Delta system.

We designed the filters to be quick and easy to replace. Simply remove the old cartridge and install the new one with simple twist and lock quarter turn mechanism.

After you’re done, the filter cartridges can be thrown away. They cannot be recycled but are not hazardous waste, so standard disposal is okay.

How long do the batteries last? Is there an AC adapter I can use?

The system is designed to only be used with AA batteries. AC power cannot be used.

The 3 included AA batteries last at least 2 years with a multiyear battery life.

Why do I need to flush the system for 10 minutes after install?

The flush primes the filter, ensuring you don’t drink gritty or off-tasting water later and the filter is saturated for optimal performance. Until the flush is done, the water might not meet the taste or clarity you expect from a new filter.

The filters are made of food-grade, nontoxic materials, so the flush water is not dangerous. However, we recommend caution when trying to re-use this water by watering plants as the carbon particles may affect sensitive plants.

How do I know the filter is working?

There are a few signs you can look for to tell if your new filter is working.

  1. Improved taste and odor: To test this, you can sample regular tap water from a separate faucet and do a side-by-side comparison against the filtered water.
  2. Clean water appearance: No visible particles, cloudiness or discoloration should be present.
  3. Proper flow rate: A dramatic decrease in flow rate could indicate clogging. Check your lines for debris or your home's water quality. The more contaminated your water, you may need to replace filters more frequently.
  4. Effective chlorine reduction: You can use a chlorine test strip to confirm the carbon filter is working.

Does this filter treat the water to a Reverse Osmosis level????

Asked by: Dee Anne
Hi Dee Anne, Thank you for your question about the Delta Faucet model DWQ3501510. This high flow filter does not treat to the level that a reverse osmosis system would. Please reach out with any additional questions! Best Regards, Bryan Digital Communications Specialist
