Good filters, slow delivery

I'm a repeat customer, this time I got the GAC Filter Cartridges and a set of Carbon Block Filters. They fit my system perfectly as always. The water quality has stayed consistent over the years, which is why I keep coming back. My only small gripe is that shipping took 5 days to reach my home in Florida this time, a little slower than my previous orders. Still, the products are reliable and I appreciate the consistency.

Whole house system, excellent!

I ordered the Crystal Quest Whole House Water Filter and it's been great for our family! The water quality improved so much, the taste is noticeably better. Installation took a bit of time but was manageable with the instructions. I will definitely be back for replacement filters!

Good deal on replacement filters

I needed new GAC Filter Cartridges and was looking for a good price. Crystal Quest had a bundle deal for several cartridges, which saved me a bit compared to buying them individually. Shipping was free because my order was over $100. It felt like a solid purchase.

Reliable filters, consistent quality

I've bought replacement filter cartridges from Crystal Quest several times now, mostly Sediment Filters and Carbon Block Filters. This latest order was just as good as the others. Shipping was free because my order was over a hundred dollars, which is always nice. They arrive quickly and are easy to install myself. I keep coming back because their products work well and are dependable.

Reliable filters, consistent service

This is my third time ordering replacement filters for my Under Sink Water Filter from Crystal Quest. The Sediment Filters always arrive on time, usually within 5-6 business days to New York, and they perform exactly as expected. The quality has been consistent across all my orders, and the website checkout process is always smooth. I keep coming back because I know what I'm getting, and I trust their products to keep my drinking water clean.

Good filter, quick delivery

I ordered a GAC Filter Cartridge. It came fast, took 3 days to reach me in Arizona. It fit perfectly and the water tastes better. No issues with the order.

Decent RO system, long shipping

I purchased an under sink Reverse Osmosis System. The installation was straightforward enough, and the water quality improved a lot, which was the main goal. My only real complaint is that it took almost two weeks for the system to arrive after I placed the order, even though it said in stock. Tracking updates were a bit slow too. For the price, it's a solid system, but they could definitely speed up their delivery times. Customer service was helpful when I called about the delay, though.

Decent RO system, shipping was slow

I bought a Reverse Osmosis System for my kitchen. The system itself seems well-built and the water tastes much better now, so that's a big plus. Installation was pretty straightforward with the instructions they provided. My main complaint was the delivery; it took nearly two weeks to arrive after I placed the order, which was longer than I expected for a standard shipment. A little more transparency on potential shipping delays would be helpful, but overall, the product is good value for the price paid.
