Juan Guerrero came to replace my under the sink water filters easy yes? Nope!! My tank was leaking so Juan replaced that and I ordered my filters from Apollotex company thinking that was the correct way not only did they over charged me but sent me a defected filter that started leaking before Juan left. When I was talking to Juan I learned I could order my filters from Sedna (909)217-7797 which is the company that installed the system. I did not realize water softener and drinking system was two different companies. Thank you Juan for your personal and professional personality. I will always ask for you by name.

Dependable and knowledgeable a professional company
I purchased two systems from Sedna Water Softer oct 2024
I'm very impressed with the product
Our health is better and my kids skin they don't need to use medicine lotion anymore, our hair is also healthier
Is a peace of mind knowing we are drinking quality water without having to buy water bottles and our laundry also feels better and cleaned,
This was the best decision we made for our family,
Is been one year since they installed the systems and the salesman Juan call to remind me we can change the filters
He cane and check the filters we were both surprised the filters were still white they look brand new
What a relief we been drinking pure and quality water for cooking taking showers and doing laundry.
With a system that is 💯 percent what our expectations wanted for our family's health.
I want to thank Juan the salesman and Sedna Water Softener for a fast and prompt service they meet all our expectations
Thank you so much

We love sedna
Had this system for 3 years. Needed a filter change and general maintenance per usual protocol and service was great. Our technician was fast, professional, and very helpful with anything we needed. I've recommended this company to countless friends and family and had zero complaints. Fantastic product and customer service all around, try it out, you won't regret it!

A must have for those serious about health and hydration.
I went from questions to completely understanding the process. This company is a must have for my home and now my athletic business HAMMERS ELITE ATHLETICS. My professional athletes went from drinking the water at the gym to having the system in their homes. Everyone also loves how soft it is on your skin when you take a shower. Also when I wash my car, this water so pure leaves no water spots.Thank you! 🫡

Extremely Satisfied Customers!
The Sedna Water Company in Rancho Cucamonga deserves five stars plus for their excellent and outstanding service when they recently installed our Reverse Osmosis Apec Filtration System. When we initially called for the installation, Juan, the owner, was very kind and helpful in setting up our appointment for the installation for the next day. Rene, the technician, arrived at our home the next day as promised. Rene, having over 25 years of experience with installing these types of systems was very efficient and very helpful in explaining details of how the system works. On the day after the installation, Juan followed up to assure that we were completely satisfied with the installation and that the system was working properly. We could not be more satisfied and pleased with the professionalism and workmanship of this company. We highly recommend them to anyone who needs this type of service. We will definitely call them in the future if we need similar work performed in our home.
Danny and Becky Manolis, Satisfied Customers!

My experience with Sedna Water was…
My experience with Sedna Water was great, Juan really sold me on a system that was most beneficial for my family! We just moved into a new home with poor water quality and we were interested in different options, and now I can rest easy knowing my water is safe! The installment process was smooth, and timely. Both Juan and the installer, Rafael were both really knowledgeable about the system and the app!
I’d highly recommend it to anyone!

Amazing Product and Experience
Sedna Water filter and under sink alkaline water system is life changing. I had no idea how bad/hard the water was in my area. They came to the house, tested the water, and had it installed within a couple of days. The alkaline water tastes better than any bottled or filtered water I’ve ever hard and my family loves it. Best part is they had the best pricing by FAR!!
Even post installation Arturo and Juan are more than willing to answer any questions and help in any way. 10s across the board.

Now this is a company you will would want to work with!!! I don’t typically write reviews but this deserves it honestly. First of all, the customer service is out of this world. They respond almost immediately and wouldn’t make one wait for days to get a response. Second, they DO NOT rip you off. Everything they do is with proper care and service and they are not just here to take your money. Lastly, ever since we’ve had the Sedna water filter in my home my acne flare ups decreased and I noticed having lesser eczema episodes as well. Such an amazing company with great staff. Special shout out to Juan!!! Always on top of everything and such a great conversationalist too!!

Overall, our experience with water treatment has been positive. The taste became crisp and clean and gave us a peace of mind that harmful contaminants were being removed. The service provided by Sednawater was awesome. Juan has great customer service and knowledgeable as he answered all our questions and explained in detail the water treatment process. The installation was smoothly and neatly done.
