Informazioni su Crystal Quest Water Filters
Scritti dall'azienda
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.

The water was cloudy and tasted funny for a while. I think it’s clearing up. I now that’s to be expected though. So glad to have my water filtered.
Thank you
30 luglio 2026
Risposta di Crystal Quest Water Filters
You've got it exactly right and I'm glad you said so, because that first cloudy glass can make some people worry.
Two things happen on a brand new carbon system. Fine carbon dust washes out of the fresh media, and air gets trapped in the line. The air is usually what's behind the milky look. Next time, try pouring a glass and watch it: if it clears from the bottom up, that's air working its way out rather than anything in your water.
Both tend to settle once the system has run a while, and the taste comes along with them. A little trick, for you next time and for anyone reading this, is to let a new system or a fresh cartridge run for a bit before you drink from it. That flushes the dust and clears the air out first.
If it still hasn't cleared, send over your order # and any other info you'd like to share to help@crystalquest.com and I'll take a look.
Glad you're up and running, and thanks for sharing what you saw. It helps the next person!
They deliver no matter what
These products are reasonable for a whole house system. My filters were lost in the mail so they send a new batch with ups. That is service
Thank you

We all know the feeling when a package just stops moving in transit, so I'm glad we could get a fresh batch out to you and put it right quickly.
We appreciate you taking the time to share this review, and I'm happy the whole house system is treating you well.
Wonderful customer service first off
Wonderful customer service first off. I had about 1000 questions about the filters and all the different and I got a prompt and thorough reply to every email I sent ! Also the filters came in quick and the quality is great! I’m happy to have my filters again in my new place. I feel much more comfortable showering and drinking the town water now :)

Ask away, that's what we're here for! We always encourage questions so you understand exactly what you're buying, and why. The ones people ask before they buy are usually the ones that save a mess later. Plus, now you're more familiar with your system.
So glad you're settled into the new place and happy with the water! If anything comes up while you're getting used to the system, just email help@crystalquest.com and we'll sort it.

Great filter quality and minimum drop pressure. Fast delivery and great communication for customer support

Risposta di Crystal Quest Water Filters
Low pressure drop can be a hard thing to get right, so it's nice when somebody notices. It's a big reason we build our own systems here in Kennesaw and have spent decades continuing to refine and improve our system designs.
Thank you for the kind words on delivery and we are very happy to hear about your experience with our support as well!

Thank you for your review Jim! It can be easy to under describe filtration systems in some cases, or even oversell a spec sheet. But we're glad to hear that our website had all of the information you needed to make an informed decision. Plus, we always want customers to open the box and find exactly what you read about!
Very happy to hear it shipped quickly, smoothly and is doing it's job so well!

I expected to receive O-rings with my 3 filter combo pack but didn't receive them. Perhaps I should of asked but there was no field available.

Risposta di Crystal Quest Water Filters
Hi Joseph - thank you for sharing your experience with us. As you mentioned, there's no field on the product listing to request or add them, and that's a gap of ours to fix, not yours.
If you would kindly send your order number to help@crystalquest.com I'll make sure O-rings get out to you at no charge. Or call 1 (800) 934-0051 and someone can would gladly help out on the phone in about two minutes.
Again, thank you for sharing your experience with us. This is the kind of thing that can quietly frustrate people who never mention it, so you've helped not only the next person, but our team as well so we can improve our listings.
5-star arsenic filter
The filter arrived quickly (even ahead of schedule)! We installed the filter in our basement on the water line that runs to our refrigerator. (Installation should be done by a plumber, or someone with extensive plumbing experience.) We followed the instructions and ran the refrigerator’s water dispenser for 10 minutes after installation. At-home arsenic testing showed a significant reduction in arsenic to a safe (almost undetectable) level! I’m thrilled to be able to use water and ice from our refrigerator after a year of purchasing bottled water and bagged ice! This filter will pay for itself within about 2 months in our household.
23 luglio 2026
Risposta di Crystal Quest Water Filters
Thank you for sharing this great review! We’re thrilled that your filter arrived in a timely manner and that you were able to see such a significant reduction in the arsenic reading after installation. We also appreciate you mentioning the importance of proper installation and following the recommended flushing instructions. Being able to confidently use the water & ice from your refrigerator again, especially after a year of purchasing bottled water and bagged ice, is exactly the kind of difference we hope our products make. Thank you for choosing Crystal Quest!

Still a satisfied customer
I have been using this Quest item in both of my homes. I am impressed by not only the performance of the big blue filters but also the staff personnel that I have dealt with over the years. Their professionalism and knowledge of the product has made me a return customer.

Thank you very much for your kind review. Also great news, we have a variety of countertop systems that sit right on the counter and connect to your faucet! If you reach out to our team at help@crystalquest.com or (800) 934-0051, they can point you to a countertop model that matches the filtration you have now.
System still leaking after o-ring replacement
Even after replacing all six o-rings, i'm still getting leaks. Our system is 8 years old. We are thinking of switching to a new one.
20 luglio 2026
Risposta di Crystal Quest Water Filters
I would like to start by thanking you for choosing our system for continuous use over the past 8 years. I'm sorry that you are still dealing with a leak even after replacing all of the o-rings. On a system that age, a persistent leak can often be something a specialist can help pinpoint quickly, such as a worn housing, a seating issue, or over-tightening, and it might not always be a sign the whole system is done. Please reach out to our technical team at help@crystalquest.com or (800) 934-0051 with your model information, and someone would be glad to help you figure out whether a small fix or a replacement makes the most sense.
