Why Choose Praz

A few reasons why we stand out…
Diamond Icon

Platinum Service

As a locally owned business, we take pride in every one of our customers. Flexible payment options, free in-house quotes, and frequent “check-up” calls are just few of the ways we try to maintain our relationship. When you contact Praz, you are not forwarded to a call center. All of our staff is well-trained and have had years of experience in water treatment.

Save Money

In the long run, RO under sink drinking water filter systems are considerably cheaper than exclusively buying bottled water or subscribing to a jug replacement service. On average, our drinking water filter systems need to have their carbon filters replaced 6-12 months. The membrane needs to be replaced every 2-3 years and that costs $42. The average American Household spends $100 per person a year on bottled water. When storage, transportation, and refrigeration costs are factored, it becomes apparent that an RO system is an investment that pays itself out throughout its life cycle.

Best Taste

Our state of the art Under Sink Drinking Water Filter System guarantees you the highest level of purification for drinking. Treatment plants use chlorine to get rid of bacteria, parasites, viruses, and other harmful microorganisms before drinking water is distributed to your home. Unfortunately, this can leave a sulfuric or chlorine type taste. With extensive 6 stage filtration, the RO-500 brings you decent quality taste alongside NSF approved filtration.

Bought a water softener system a week ago. Their systems are really powerful and efficient,. All the other companies I spoke to seemed to not be sure on my exact water requirements but wanted to push for an installation anyway.

I haven’t actually purchased anything from Praz. I’m writing this to give a review on how knowledgeable Praz’s manager was regarding water purification. I’m a prospective customer and he spent almost 30 minutes talking to me on the phone to teach me about mineral reduction in RO filters, pH enrichment in alkaline filters, etc. Once I’ve completed my research on what I want to purchase, I am for sure going to Praz because of his knowledge, patience, and friendliness.

We’ve been with this company for many years and have always had great service and great tasting water. They do tend to call at random times of the evening to remind you about changing your water filter but they always show up on time and do their thing. I never understood how people could live without a water system.
