Houston Water Filtration System Guide

There are various types of home water filtration systems available, with the price varying from $20 up into the thousands. Water filtration systems are not all created equally. Instead, they are created to address different problems. For example, water filtration system A may filter lead and microorganisms, while water filtration system B will only filter lead out of the water. That is not to say water filter B is a lesser quality, rather it is created for the specific needs of a home’s individual water supply. This Guide to Water Filtration will explain the different types, their purpose, and how to select the type of water filtration fits your needs, as well as your budget when you are planning to install a water filtration system in Houston.

Whole House Water Filtration

A whole house water filtration system (also called a point of entry system) connects to the main water line entering your home, and provides filtered water to all water outlets in the home. By locating it on the main water supply line before it enters your home, this provides filtered water at every tap, appliance and even the hot water heater.

Determining the Type of Water Filter to Fit Your Home’s Needs

The type of water filtration system in Houstonyour home requires will depend upon the specific contaminants in your water. If your water comes from a municipal source, the standard contaminants your system will need to address are chlorine and chemical compounds, sediment and the presence of minerals. The most accurate means of determining the contaminants your filter will need to address is to have your water tested.

Water Softening and Water Filtration

Water Softeners treat the minerals that cause hard water, whereas water filters are designed to remove a broader range of contaminants. Both may be combined in one appliance known as a water conditioner.

The common water contaminants removed by a Water Filtration System in Houston are as follows:

  • Sediment refers to visible particles in the water. Water supplies with an excessive amount of sediment require phased filtration where water is filtered through progressively finer filters.
  • Chemicals are by large removed with carbon filters. Chlorine is the most common chemical present in municipal city water supplies.
  • Iron present in water supplies is of two forms, ferrous (dissolved or clear water iron) and ferric (red water iron). Red water iron and rust particles are removed with a sediment filter, whereas clear water iron is removed through oxidation or ion exchange.

Features to Look for in a Whole House Water Filter

Flow rate – measured in gallons per minute (GPM), flow rate determines the quantity of water available for household use. Don’t select a flow rate less than 10 gpm to enjoy uninterrupted water pressure. A Benjamin Franklin Plumber can calculate your home’s required flow rate in a water filtration system in Houston.

Filter size should be large to provide a longer service interval. It will also allow for extra water flow and a higher water pressure.

Water filters are divided into two categories, level-of-use and point-of-entry.

Kitchen water filters are included in the point-of-use category, meaning they filter water in a single location only, usually the kitchen sink. Point-of-use filters include water filter pitchers, or faucet-mounted and under-sink filters. Most point-of-use water filters use carbon filters to absorb impurities (especially odors).

A reverse osmosis water filtration system in Houston, possesses semi-permeable membranes for more effective filtering. Reverse osmosis filtration can remove nitrates, arsenic and other contaminants that carbon filters alone cannot remove.

Point-of-Entry Systems

Point-of-entry systems (whole house water filters) work to filter water before it enters the home. The units are typically installed in the main water line before it enters the home. They are effective for removing visual contaminants like dirt, sediment and rust. They provide a fast flow rate with less clogging. To remove cysts and other biological contaminants, point-of-use filters are in conjunction with whole house water filtration systems in Houston for clean, sparkling clear great tasting water.

Water Filter Pitchers

Water filtering pitchers and dispensers are a low cost solution for those who want better tasting water without investing a lot of money. The downside is they take up space in the refrigerator.

Faucet-Mount Water Filters


Faucet-mounted water filters are easy to install with most kitchen faucets, just remove the aerator and screw the filter on. Otherwise an adapter may be necessary. They also provide clear, better tasting water.
