Buyers Guide:

There are five questions to ask before you decide on the best water filter system for your home.

1. Drinking-Water Filtration or Whole House Protection?

There are two different types of systems that you can have installed in your home.

Point of Use (POU) systems: These are installed beneath your sink and act as reverse osmosis systems.

Point of Entry (POE) systems: These will filter all of the water that enters your home.

You'll have to decide if you want to treat only the drinking water from your kitchen faucet, or all the water that enters the building. We recommend a combination of home wide water systems and additional refined treatment for cooking and drinking.

2. Are You Using City Water or a Private Well?

Public water supply is relatively safe to drink and use. However, there are many boil water notices. Every day, there are approximately 658 of these alerts issued by water districts and cities due to ruptured pipes or contaminations. Also, 40% of private wells contain E.coli and other contaminants at any given time. Investing in UV water purification systems can protect your entire home from these harmful microorganisms.

3. How Many Bathrooms Do You Have in Your Property?

Often, water treatment systems are based on the maximum water flow rate throughout your home. For instance, if you have the dishwasher running, the shower running, and the washing machine on in the morning, this could help you to determine the size of the water treatment system needed to provide your home with a safe amount of purified water.

4. How Many People Live in Your Home?

In a typical 24-hour period, how much water do you think your home uses? This can often be determined by the number of people living in your household! Consider this before you decide on which water filtration system to purchase.

5. What is in Your Water?

Your water treatment needs can be evaluated when you have found out precisely what is in your water. To find out precisely what is in your water, contact an ESP water specialist, or locate an ‘Annual Water Quality Report’ from your water suppliers website.

It is a requirement of the EPA for all community water systems to prepare and deliver water quality reports each year. This is also known as a Consumer Confidence Report (CCR) for their customers. Visit this website for more information. Furthermore, here is a comprehensive list of certified water testing labs by each state.
