Choosing a Home Water Filter

Deciding which water filtration system you need can be a daunting task. Here are a few considerations when selecting a home water filter system:

1. Are you using city water or a well?

Statistics show that there are approximately 658 boil water alerts issued every day by cities and water districts in the U.S. due to contamination or ruptured pipes. Also, studies commonly find that 40% of private wells contain E. coli and/or coliform bacteria at any given time. We generally recommend UV water purification systems for whole home protection from harmful microorganisms. Other water treatment methods are also typically recommended based on types of contaminants and contaminant levels in your water.

2. Drinking Water filtration or Whole House filtration?

Are you looking at filtering/treating just the drinking water at your kitchen tap or would you like to treat all the water coming into the home? Often the best solution is a combination of whole house water treatment and further refined treatment at the kitchen sink for drinking and cooking.

3. How many bathrooms are in your home?

Some water treatment systems are sized based on the maximum water flow rate though your home. For example, in the morning you may have a shower going, a toilet flushing, the dishwasher running, and the washing machine on…all at the same time. How much water will flow through your home during these peak usage times? Knowing the number of bathrooms in a home is often a quick and simple way to determine the size needed of specific water treatment systems.

4. How many people are in your household?

Other water treatment systems are sized based on the average total water used by your household on a given day. In a typical 24-hour period, how much water is used in your home? In general terms, knowing the number of people living in a household can often give clues about household water usage, and therefore what size water filtration system would be best suited for your home.

5. What’s in your water?

Knowing what’s in your water will play a big part in evaluating your water treatment needs. For example, if you have lead in your water, an ESP water specialists can direct you to a system that can remove lead. To find out what’s in your water, locate an “Annual Water Quality Report” from your local water supplier’s website.

The EPA requires all community water systems to prepare and deliver an annual water quality report, sometimes called a Consumer Confidence Report (CCR) for their customers. To find your local Consumer Confidence Report, visit this EPA website. Also, for further analysis or well water, we highly recommend a more thorough water test. Here’s a list of certified water testing labs by state.
