"Since we moved into our new house with an inherited hydrodynamic cavitation system, we thought we better do some research on it and ask the company the merits of the system & what were the service intervals for changing out the consumable filters that accompany the system. I gave a call to the number listed on my device and got a call back instantly from Keith. Keith is quite the expert and very passionate about these water systems as he should be. He gave me the information. We had some issues with the AO filters which are not really rated to be outdoors (plastics withstanding the elements) a few months later and I notified him. Keith offered to come and check it out even on a 3 day-holiday weekend as he was concerned that we wouldn’t have water that week. His level of expertise and dedication is amazing & commendable! I later found out that he was caring for/dealing with a sick/injured person at home during this time. He proceeded to upgrade our filter system as HDC no longer uses the smaller A/O filters to the more robust GE system. Although we still filter the water out of our sink tap due to habit, the times we drank directly from that faucet were totally fine.  We are happy to report a reduction of bacteria/pathogens in this great tasting water. There is no more heavy metal taste as you get with many taps in Honolulu.  The water feels softer kind of like the water I have had in Japan. I feel like it’s contributed to smoother skin & softer hair.  I can truthly say that HDC stands by their decade warranty as is clearly true with the level of service he’s provided us (and we inherited new system, albeit it was fairly new),  I read somewhere that they have NSF-372 certification for this system which is comforting.  Keith mentioned that they have been outfitting large hotel/property corporations with his systems. I can’t remember which large chain it was, but it would be good if most if not all hotels were so informed about their water systems for their guests’ safety & peace of mind. Such a small investment for a big reward. Mahalo!"

"I installed HDC device and threw a super bowl party after the 5 day break-in cycle was complete. After 40 people spent the night jumping in and out of my 10,000 gallon backyard pool/jacuzzi it was expectedly a bit cloudy, but by the next day (after leaving the pump running) was once again crystal clean and clear! I tested the water and it was completely balanced. Also, no one used my outside shower and prior to installing the HDC Device everyone would use the shower. Couldn’t be happier with our new pool, thanks guys!"

Bill Saugus Mass | A HDC Products Customer

"I purchased the HDC Products home system 4 weeks ago and I have noticed several great things. The acne on my face has gone away, my coffee tastes really great and the toilet bowl no longer has a ring. 
Thanks, Keith."

Jelena D. | Waipahu, Hawaii

"We like the water system very much.  Taking a shower is a joy, no more slippery feeling but when I dry off and my skin feels clean and smooth.  Also, I notice there are less water spots on our dishes and in the sink, and my windshield glass looks a lot cleaner.  Our grass and plants look greener and healthier, like you said, which makes us very happy.  I happily recommend this system to anyone looking to improve their wellbeing."

Ronald | Waipo, Hawaii

"The water is really great because we no longer need to wipe down the water from the glass and walls. Also, there is no more chemical smell. Just great!!"

Sharon | Honolulu, Hawaii

"We are loving the water! We hardly have any toilet bowl rings anymore and spend less time watering the lawn. Plus, our water taste great from the tap. There are many improvements felt in our skin, hair and so on. Thank you."

Mark | Kahala, Hawaii

"Awesome product!…My skin feels so much softer and my hair feels wayyy softer…Super nice! Thank you!!!!"

I wanted to let you know of the spectacular results I have seen in my pool following the installation of the HDC Products pool device. I will be honest that I was very skeptical at first. I had never heard of the science used by the product. I also couldn’t find much documentation on-line about the HDC Products device either. I did find some pool servicer blog posts that shared my skepticism.
I am happy to report that this product is the real deal. It works – period.
I have a 43,000 gallon pool that has always been impossible to maintain. Not only does my pool have a natural rock formation cascading to the floor of the pool, but I also have a large Kiawe (Hawaiian Mesquite) tree that constantly showers small leaves into the pool. I also keep my pool heated to 89 degrees. The combination of these factors, along with using a salt system, has resulted in constant algae problems, and cloudy water. Too many times I have had to add extra chlorine during the summer months. I have also required the use of phosphate removers to help get the water clear. And to be honest, despite all of that, I didn’t think my pool looked too bad. That was another reason why I was reluctant to add an “unproven” piece of equipment.
Within the first few days following the installation of the HDC device, my pool started to transform. What I thought was clear water before was nothing compared to how the water looks now. The pool water looks almost perfectly clear in nature. I have never seen the water that clear before, except for the day we filled the pool. I can stare at the deep end of my pool, and it looks like there’s no water in the pool at all – that’s how clear the water is. That’s pretty incredible, as the deep end of my pool is over 12 feet deep. I have also noticed areas that algae grew, no longer exist. Since installation, I have not brushed the walls of my pool. The rocks in the pool always had algae issues. After just 10 days of the HDC Products device installed, I stared to see areas of rock completely absent of algae that was there prior – all without brushing or adding additional chemicals.
I know there are many who will share my initial skepticism. A device that doesn’t use chemicals, doesn’t use any electrical source, and doesn’t wear out, is somehow going to allow my pool to look better, smell better, and end up using less chemicals in the process? That is a very tall order for any device. Yet, somehow the HDC Products device does it. I’m now convinced that the HDC device process of momentarily super-heating the water passing through it is doing two important things for my pool water. First, it is destroying the phosphates that has kept my pool cloudy for years. Second, it is killing the food supply the algae needs to grow. With both of these gone, my pool has never looked as good.
I know even after someone reads this letter, they may think I’m lying, or somehow this can’t be true. For those of you, I tell you the HDC Products device will work for you.  If it could do what  it did to my pool, it will easily do wonders for your pool. And if you want to know if I’m a real person, I’d be happy to speak to anyone and share the progress pictures and video of my pool transformation.

WAIKIKI HOTEL POOL OWNER | Waikiki, HI

"My hotel in Waikiki has two spas that were being drained every other night. I have not needed to drain them since the HDC Products device was intalled. 50% less chlorine is being used."

John Fefferis | Hawaii

"Thank you for your referral to Paul Tamura. I’m quite pleased with his work. Enjoying the benefits of your system."

Lisa Driver, MI

"There is a difference when taking a shower, the water is drinkable and there are NO visible water spots on my sinks and faucet due to the calcium build up. We love the system!“

Amber Ricci | Honolulu, HI

“We got our home device from Keith about a month ago at our new home for our pool and jacuzzi and we love it ! We noticed right away there is no chemical smells anymore, and the water feels so pure on our bodies. Also my skin is not drying out like it has from typical pools and jacuzzi. We are very health conscious and this has definitely upgraded our lives. We will recommend this easy to set up system to our friends ! Thank you, Keith!”

S and B | Homeowners

“The water at the house is spectacular. Bree has noted a dramatic lessening of the drying effects her hair has been subjected to previously. Additionally, the water actually tastes amazing.  We have not once noticed the previously obnoxious chloramines odor that has been prevalent for long. Thank you so much for the installation of this fine product on our home!”

Michelle | Homeowner

“Congratulations on your new success of being innovative and proactive in developing a successful product for the environment, water and people! I am so happy and proud for you! I am wishing you SO much success in your new area of expertise! 
Thank you for our system. We love it! Our skin and bodies thank you!”

Suzy | Kailua, Hawaii – at daughter’s home

“Thank you so much for setting us and our daughter’s homes up with your whole house filtration system. I have suffered for years with the City and County water making my skin so dry and itchy. My eyes burned like acid acid when washing my face. Our baby grandson has eczema and we are grateful that with the system installed, it helped clear it up.Our yard and plants love it too. 🙌 We have all benefited and are very pleased!”

Tara | Homeowner

“Amazing fabulous results! Today, one week after being filled and 1 day after the cavitation device was installed, I went to perform the weekly rinse of the spa filter. The filter was obviously dirty. There were tiny black pieces/bits here and there and parts of the filter were darker and obviously dirty. This has never happened before. So, I treated this as I would the monthly filter clean by replacing the filter with my clean spare. I will soak the well rinsed dirty filter in water and degreaser, where it will remain soaked overnight. Wow! This cavitation device is more than doing its job!! Thought you both would like to know this bit of news!!!!
PS – I’m using the spa so much more frequently than before."

Homeowner

“If you own a hot tub and don’t want to use chlorine anymore, then this is the device for you! The HDC portable spa unit will purify your hot tub’s water and is installed in the plumbing circuit of your spa.”

“After installing the HDC Water Filtration System in our home, my flowers started lasting longer! Your flowers will last nearly 3 weeks after using their water in your home!”

Nani | Nanakuli, Hawaii

“A big MAHALO to Keith Morrill and HDC PRODUCTS INC!!!! Thank you plenty for providing and installing your patented whole house water purifier in my parents home in Nanakuli. They no longer have to deal with lifting 5 gallon bottles atop their water filter. The water tastes great and feels amazing on the skin after showering. I’m so glad I chose your system over others. Thank you again for caring for our Hawaii nei and her people!!!!”

Larry Grasse | Home Owner

"We had HDC PRODUCTS install the home and pool system. Great plumber, great service! We have noticed our water now leaves no water spots on our showers, cars, and windows, and our lawn is greener. This might just be me, but I’ve noticed that I use 1/4 of the shampoo that I used to. I had black mold and was told I could not get rid of it. After installing, no more black mold! We also have properties in Washington, Leavenworth with a well, which we are now setting up, as this product works great with wells. Unreal – this product WORKS."

Doug | Homeowner

"Good, the water looks clear, less spots especially on glass items. Like the compactness of the whole house system. Clothes feel softer. The only thing is the house pipes are cleaning out and the oldest faucets leaves a metallic taste compared to the other faucets. The newer faucets were changes within last 2 years, the water taste better than the oldest. Have plans to change all faucets in our upcoming renovation of the kitchen and both bathrooms Doug. "

My wife and I are very close minded to western medicinal remedies.  We’re always looking for homeopathic solutions whether a more vegan diet…refined essential oils…filtered water…etc.
When we first heard about hydrodynamic cavitation…skepticism was our first reaction…
But since my wife has had an unresolved skin condition….any possible solution would be welcomed.
My wife’s skin condition has improved and I personally drink literally gallons…even our garden plants seem to be happier!

John Curiciuo | Homeowner, Lynnfield MA

"My wife said to me the other day, honey do we still have the system for the water in the house to I replied yes why she replied my skin has become rough and no longer soft.  So I wanna head and change the cartridge filters inside the system and 2 days later my wife syud my skin is softe and smooth again what changed and I told her I simply changed the filters. 
When the filters become saturated the quagulated metal will re-enter the water in the home. "

Kazu | Homeowner

Rose Donovan | Homeowner

"I am I am very extremely happy with the water system. My skin is less dry since using it. My hair is soft with less build up. Are used to a clarifying shampoo every week to get rid of the buildup in my hair, and I no longer need to. The water taste better. It is pure and clear, and we no longer use any bottled water"

David Gaudet

"Since installing the HDC water product, after about 4 days  the stains on my tub have gone, my skin is cleaner and feels much better, when I shower the soap falls off right away with a cleaner longer lasting feel. and the ice tastes much better!"

Carla Cummings

"I've had this water system in my house For about three weeks now I have used less dish detergent in my dishwasher. I also use less detergent in my washing machine. My dishes in my dishwasher come out so much cleaner. I also have eczema on my ankle which is pretty much gone and my Face and skin feels like a baby, I now hardly use any cream on my body, I believe in this product it’s absolutely amazing!!!"

Terry

"I have been a boat owner for over 15 years and I have always had the problem of my freshwater smelling really bad.
Knowing the properties of structured water, I filled my freshwater with the HDC device and the results were fantastic, no more smelly water AT ALL!!"

Kalia Keawe

"My grandma installed a new system on her in-ground saltwater jacuzzi. We can go under the water now and our eyes do not burn. My skin no longer gets itchy from staying in for long periods of time. I actually come out feeling cleaner than taking a bath. "

Lisa Driver, MI

"I installed the HDC water purification system in my house when I felt the difference at our neighborhood association pool. We are really happy we did because my hair is never felt softer and I can feel the difference with my aging skin. I highly recommend you give it a try, you’ll never go back to untreated water again."
