Water Delivery vs In-Home Water filtration System


On average, a home delivered 5-gallon bottle of water in runs around $7 or $1.40/gallon. Even if your household drinks only 1 gallon of water a day that’s over $40 per month!

Puragain Water’s 5 Stage in-home water filtration system will produce 50 gallons of superior quality drinking water each and every day, right from your tap, for just $26/month.

That’s just 50 cents a day to get 50 gallons of the purest, cleanest water right out of your faucet each and every day of the year! That’s only 1 penny per gallon of water!!!

Free Professional Installation

No need to break out your tool belt for this one. This reverse osmosis system comes with free professional installation. We will schedule an appointment for you with one of our installers, usually within a day or two of your purchase. Our professional installer will take care of everything including the installation of your system and your new water faucet.


Annual Water Testing

Rest easy knowing that your system will always be working perfectly with annual water testing free of charge.

Unlimited Service Calls

With unlimited service calls, if you ever have a problem with your system we'll send someone out right away at no cost to you.

Puragain Water's customer service and installation were absolutely amazing! The quality of the water in the entire household is also incredible. The attention to detail throughout the process by Chris, the sales water specialist, and David, the installer, was phenomenal. I would highly recommend Puragain Water if you live in Southern California. Definitely opt for the alkaline water filter as well as it produces amazing drinking water. One of the best home services I have ever experienced!

You would be a fool to not use this company. Everyone is amazing and an all-star team!!!!! From sales on down. Chris was a great breathe of fresh air and make sure you ask for Larry when it comes to install. He's a great and very personable guy. Monday quote with a Tuesday install. Absolutely awesome!!!!

Just had our consultation with Michael M. and I'm so pleased with his level of service. He was so polite, and very pleasant. He explained everything thoroughly and asked if we had any questions. He showed us online what the system looks like as well as where the spigot would go. He walked through the financing and also the process during installation. I'm looking forward to experiencing the system and will update my review accordingly

I just purchased the water system for my kitchen. The water is great and much cheaper than buying cases of water. The service was top notch from start to finish, the sales associate was very professional and the plumber was also very professional and kind, there was no mess and service was fast. I'm very pleased with the water it taste great, I'm mad at myself for not doing it sooner. Very happy with Puragain Water, I'm recommending this to everyone that wants to save money, time and our landfill.

Awesome services and great system set-up. Michael and Larry were on time and got the job done in a timely matter. The install on the system was clean and secured properly. Once the job was done they cleaned up and took all the empty boxes. If you want someone to come out ask for Michael. He was very detailed with what you were getting and showed the difference between your current water and their water system. Michael also followed up to make sure all my questions and concerns were answered.

Pretty damn phenomenal. I had been debating and researching water softeners and filtration for quite sometime now when I just happen to come accross a Facebook ad for Pureagain water and their filtersorb unit. I inquired and made an appt. I liked what I heard from Lonnie when he met with me at home. I decided to go through with it although my work schedule got in the way a bit. Lonnie was able to get his installer out the very next day to do a great job installing our filtration unit. We couldn't be happier. Thanks again.

Love Love my whole house filtered water plus I had the alkaline installed as well. Big difference on water change. No more hard water on my shower doors, in my dishwasher, or anywhere else. The water taste so clean and fresh when drinking it. It was the best investment I have made and I wish I would of done it a long time ago. I save money and the earth by not buying water bottles anymore. The works were very informative and super nice. Thank you again!

Lonnie and 100% family owned team are ROCKSTAR's and have ABOVE & BEYOND Service! They will come out and test your chlorine, calcium and ppm in current tap water for free, and show you how to get your tap water ppm from the really bad SD tap of 362ppm+ all the way down to only 10-20ppm! This is a MUST if you want to protect you and your children's longterm health living in the drought-ridden, sewer-to-tap SD water. Thank you Lonnie for your family's continued commitment to protecting us locals!

This whole process was so easy from beginning to end. Working with the staff of Puragain Water helped me pick out the perfect system for my family. The team at Puragain made sure we were completely satisfied from beginning to end. We are now set up and enjoying this great tasting water. Thank you Lonnie for making this an easy decision for us!
