What is a Whole House Water Filter?

A whole house water filter is a filtration system designed to remove sediment, chemicals and pathogens that may be found in your home’s water supply. The device is installed at the water entry point in your home to soften water and make it safe for domestic use. The device can transform hard water into soft water that you can drink or use to make coffee, or do the laundry. While tap water may look clean, the water supply in most cities have contaminants, chemicals and sediment as well as some pathogens.

What Type of Whole House Water Filter do I Need?

There are many types of whole house water filters on the market. Your choice of filter will largely depend on the source of your water as well as the types of contaminants in the water you use. If you get your water from the city or municipality, you may only need a filtration system to remove chlorine and sediment that might have been picked up along the way. If you get your water from a well, lake or river, you will need a whole house filtration system to remove sediment, pathogens, minerals and other impurities that may be found in the well water. The following are the two types of whole house filters in the market:

– Cartridge Filters: If you are looking for an affordable filtration system to improve the quality of water in your home, a cartridge filter may be the perfect option. However, the filtration system requires a lot of maintenance. The filters in this type of system usually deteriorate fast, so you will have to replace the actual filters regularly. Since sediment and other contaminants are normally trapped in the filter, you may have to replace your filter every 3-12 months to ensure the system does not get clogged. 

– Backwashing Filters: This is a more elaborate filtration system that cleans itself up after a certain amount of water has been filtered. This is done by pumping water in the opposite direction to wash away the sediment or filtered contaminants. Backwashing filters cost more than cartridge filters, but they do not need regular maintenance. The filters in the system can last several years before they have to be replaced – such as Home Master 3-stage system

Water Softening vs. Water Filtration

When it comes to improving water quality, there are three phrases you need to get familiar with. The first is water softening. The second is water filtration while the other is water purification. Water softening is the process of removing minerals found in hard water. This may be done through addition of chemicals to hard water followed by filtration to get rid of the salts that may be formed. Water filtration, on the other hand, is the process of removing sediment and contaminants from water. Contaminated water is passed through a serious of high capacity filters to remove the contaminants. Filtration is usually done on tap water while softening is often done on well water. In addition, water contamination is easily solvable nowadays by installing the best salt free water softener or filters in your home.

Types of Contaminants

  1. Sediment

These are solid particles and salts found in hard water. If you get water from a well, river or lake, it is bound to have a lot of sediment. 

  1. Chemicals

These are compounds used in water treatment. Chlorine is a common type of chemical found in tap water. Dissolved salts and hydrogen sulfide from well-water are also examples of chemicals. 

  1. Iron

This is a mineral found in hard water as well as tap water. Iron usually gives water a funny taste as well as well a greenish color. Whole house filtration systems can remove iron and any other contaminant found in the water. 

Selecting a Whole House Filter — What to Look for

i) Flow Rate

This is the amount of water a filtration device can filter per second, minute or per hour. Since you need filtered water for your washing machine, shower, water heater, faucets and dishwasher, you should choose a filter with a flow rate of several gallons per minute.

ii) Filter Size

The size of the filter affects the flow rate of a whole house water filter. The larger the filter, the more the water it can filter at a time. 

iii) Filter Life

Quality filters do not come cheap, so you want a filter that has a long life. You do not want to replace the filter after every couple of months, so be sure to compare the life expectancy of the top-rated filters before making a commitment. 

iv) Port Size

The best filters usually have a port size of 1-inch. While there are filters with half or three-quarter inch ports, you should choose a filter with a 1-inch port even if your home’s plumbing is 3/4 inch or 1/2 inch.

How To Maintain Your Water Filter

Now that you already know the important things to consider when buying a new water filter for your home, it’s time to know how to properly maintain them. When you take care of a water filter, you’re assured that you won’t only make your life easier, but that you’ll also be able to save money. 

It’s important to remember that it’s not only the size of the water filter that affects the quality of the water that you use. It’s also the amount of chlorine in your tap water that’s causing your water to be bad for you. Chlorine is a highly corrosive substance that can lead to cancer, birth defects, and other sicknesses. Additionally, chlorine is the major cause of chloroform and other harmful by-products that are being created in your tap water.

Here are some tips to maintain your water filter:

  • In order to keep your family healthy and safe, a good water filter should be replaced on a regular basis. The best part is that you can easily do this yourself, provided that you’re willing to spend a few minutes to change the filter. Doing so allows your own water system to be in tip-top condition. 
  • When you notice that the filter is not producing clean, clear, fresh, and refreshing water as it used to, then you need to replace it. Another sign is if the filter starts producing unpleasant odors, smell, and taste, then you probably need to change it. 
  • If you notice that the filter seems to have a cloudy appearance or look cloudy, then you need to replace the filter.
