Sobre Crystal Quest Water Filters
Escrito por la empresa
Pioneering water filtration technology since 1994
We make high-quality water the standard.
Crystal Quest has designed and hand-assembled water filtration systems in Georgia since 1994, under an ISO 9001 quality management system. We build everything from a countertop pitcher to full-scale desalination, and because we are the manufacturer, we match each system to the water it will treat instead of selling one product to everyone.

So happy to find a place that carries a external water filter that removes fluoride and many other things. It is much better than the standard filter that is inside the fridge. I hope you will always carry these external filters.

Respuesta de Crystal Quest Water Filters
Thank you for your review, Lauretta! We’re glad you found an external refrigerator filter that addresses fluoride and provides more comprehensive filtration than your standard refrigerator cartridge. We appreciate your support and look forward to continuing to provide these filters for you!

We've had a dual filter Crystal Water Filter installed in our kitchen sink for many years, and we enjoy the taste and health of filtered water. And whenever it's time to replace the filters, it's very easy to use Crystal Quest's web site to order new filters, which arrive in just a few days.

Brooks, it’s wonderful to hear that your double-filter system has served your kitchen for so many years! Just as importantly, we’re glad maintaining it has remained simple and that replacement filters arrive quickly when you need them. Thank you for making Crystal Quest part of your family’s daily water for so long.

“These people know clean water” may be one of our favorite compliments yet! It means even more knowing that both our products and after-sales support earned your praise. Thank you for the incredibly kind words!
Respuesta de Crystal Quest Water Filters
Monika, we’re sorry you remain dissatisfied, but the statement that the system “doesn’t work” does not reflect the issue documented in our communications. The concern brought to our team was that the approved 500-gallon storage tank would not fit through the installation access, not that the reverse osmosis system had failed to treat the water.
Once the sizing concern was raised, our team worked extensively to offer several possible resolutions. These included exchanging the tank for multiple smaller tanks, returning only the tank and sourcing an alternative locally, or returning the complete system. You ultimately chose to return only the 500-gallon tank while retaining the reverse osmosis system and the remaining tank-kit components.
We assisted with the return, inspected the tank, waived the applicable restocking fee, and issued a refund based on the amount actually paid for the individual tank after the affiliate discount, less the return-freight expense. Components that were retained could not be included in the refund for the returned tank.
We recognize that discovering the tank would not fit the intended space was frustrating. However, our records show that our team provided multiple options, made exceptions to our standard policies, and worked toward a fair resolution. Subsequent payment disputes have been handled through the appropriate financial channels, and we do not believe it would be productive or appropriate to disclose those details publicly.
We stand behind the extensive assistance and accommodations our team provided throughout this matter.

Top notch customer service
The staff is always helpful and no question is stupid. If the right person is not available I will get a return call. My whole house reverse osmosis system works extremely well. It was a great value for the price.

There truly is no stupid question when it comes to something as important and technically involved as your home’s water. We’re pleased that our team has made you feel comfortable asking for help, followed through with return calls, and has continued to support you after the purchase. Hearing that your whole-house reverse osmosis system is performing extremely well and proved to be a great value makes this especially rewarding. Thank you for sharing your kind words and trusting Crystal Quest.

Thank you, David.

We’re always looking for ways to strengthen our operations and create a better experience for our customers, and those are a couple of areas our team has worked especially hard on. Thank you for continuing to choose our filters year after year, we look forward to continuing to serve you!
Disappointed,
I bought a system to wash my car because of the hard water we have in AZ. Unfortunately the system didn’t make a difference and I still get deep hard water spots all over my vehicle. Very disappointed and I feel tricked.
15 de agosto de 2026
Respuesta de Crystal Quest Water Filters
Hi Jamie, we completely understand why continuing to see deep water spots would leave you disappointed. You purchased this system to solve a very specific and frustrating problem with Arizona’s hard water, and we never want a customer to feel tricked, misled, or let down.
We would like to send you a complimentary replacement DI cartridge. Based on what you’ve described, we believe replacing the cartridge may resolve the spotting, while also giving us a fresh and reliable baseline if any additional troubleshooting is needed.
In a situation like this, we would typically recommend comparing the incoming and treated-water TDS readings. Highly mineralized water can exhaust deionization resin more quickly, particularly when the incoming TDS or flow rate is high. Those readings can help us determine whether the media exhausted unusually quickly, water is bypassing treatment, or another part of the system’s configuration is affecting performance.
Please send us an email at help@crystalquest.com, call us at 1-800-934-0051, or submit a support request at https://crystalquest.com/pages/create-support-ticket so we can arrange the complimentary cartridge and help get your system producing the spot-free rinse you purchased it for. Thank you in advance for giving us the opportunity to investigate this and make it right.

Colin, we’re sorry you did not receive a response. After reviewing what happened, we found that your message was sent to service@crystalquest.com, a legacy address that had been decommissioned and was no longer monitored or connected to our support-ticket system. As a result, your message did not generate a ticket or reach a team member for follow-up.
We apologize and please be known that your request was not intentionally ignored, but the gap in our email routing was ours to identify and correct. We appreciate your review bringing it to our attention. Our team will contact you directly to review the broken spout and arrange the appropriate replacement.

Customer service and the products are great
Customer service and the products. The substitute products do not work and are a waste of money. These initially lasted me 7 yrs. I don’t use a lot of water. The others never blocked the chlorine and w/i a yr, I had to replace all of them.

Respuesta de Crystal Quest Water Filters
Seven years of service from your original products is remarkable, and we’re glad they provided the chlorine reduction you were looking for. Your experience with the substitutes makes your decision to return to Crystal Quest especially meaningful. Thank you for recognizing both the products and the people behind them!
