Excellent water filters

I really like this brand of filters. Easy to install. The best I’ve used, will continue to purchase!!!

Works well, straightforward to install. Slight moment of opaque water when turned on.

Each time I turn on the faucet there's half a second of opaque water that comes out first. I wasn't expecting that based on the instructions, but it's not an issue worth worrying about.

Long Time User

I purchase my Crystal Quest 3 stage under counter filter 6 years ago and have been buying replacement fluoride, smart, and carbon block filters ever since. As fluoride was the #1 chemical that I wanted to remove from our drinking water, I did a great deal of research prior to making my initial purchase and the Crystal Quest was rated as one of the best. I have never actually had our water tested and assume that it does what it is supposed to as current reviews still rate it as one of the best at a reasonable price.

Excellent quality & service

Very happy with my experience with Crystal Quest from start to finish! The service team is very responsive and helpful, and I love knowing the water throughout my home is clean and pure. I’ll be a repeat customer!

Always happy with my Crystal Quest system!

Reliable as usual! Glad I have an option to remove the chemicals that the government authorities (a.k.a. dipshit fuckwits) see fit to medicate me with.

Water Filter Delivery Review

Everything went as smoothly as a customer should expect. We ordered our filter and we received it promptly.

Used many times in the past.

I have owned a three stage under the counter Crystal Quest Filter for many years, along with the shower filter, and have purchased all of the same replacement cartridges on this order several times. My total overall experience, with the filter its self, and all of the replacement cartridges purchased has been very good. Up until last year, I have been purchasing my replacement cartridges from another source that did not charge any shipping costs. I purchased them from Crystal Quest last year because you did not charge for shipping. Had I known there would be shipping charges this time I probably would have gotten them from the previous source. Unfortunately, I was 95% done with my order this time before I found out from the person that I was talking to on the phone that there would be shipping charges on this order. As I really did not have the time to cancel this order and re-order from the previous source, I went ahead with this order, but was not happy to have to pay for shipping. You would think that a $170+ order would earn free shipping, it did last year, but such was not the case this time around. As they are great filters, I will continue to purchase Crystal Quest replacement filters, but will purchase them from a source that does not charge shipping.

The telephone support and ordering was excellent. Email follow ups great, delivery prompt and correct product received. Cannot ask for more than that. We have had this filter for ten years and our local fluoride-poisoned water has not killed us yet! THANKS! Barbara Lambert, retired dentist

Great Service

A bit difficult to determine what model number you need for your housing but once you know it’s easy but expensive to buy. Specially paying shipment. Also, if as a customer you are buying a cartridge, this should be sold as a kit and include o-rings even if not needed. A kit should be offered.

No fluoride for me

I've removed fluoride from my water for some time now. It affects your thyroid and is not good for your health.

We've had a triple filter system for over a year and we have been very satisfied with the quality of the product itself and the water we are drinking.

Happy with Filters

I use the above sink double filter with the Fluoride and Multi Stage. I’m happy with this setup to keep the tap water cleaner.
