4 Major Types Of Water Filter System for Whole House

To remove impurities from your domestic water, you’ll need an excellent water filter system. Water filters are responsible for supplying your household with clean water for drinking, irrigation, cooking, bathing and even swimming pools. This is effectively done by removing impurities such as bacteria, heavy metals, disinfectants and many more. In this insightful post, we’ll familiarize you with the 4 major types of water filter system for whole house.

1. Reverse osmosis (RO) filters

This is one of the best and most popular water filtration methods available currently. It is popularly known to provide excellent drinking water by removing any kind of contaminants dangerous to your health. 

In simple terms, this process is very effective because water passes through a semi-permeable membrane, leaving behind the contaminants which are then flushed down the drain. This process produces very clear and odorless water. In short, here are the simple reasons why you should use reverse osmosis:

  • Water produced tastes and smells great.
  • Systems are less expensive.
  • Very effective and safe.
  • The process is fully automated.

2. Ultraviolet (UV) filters

This is also another very effective method of purifying and disinfecting your domestic water. Technology today allows the use of UV light to purify water by killing viruses, bacteria and other harmful microorganisms found in water.

That said, this system passes the unpurified water through a UV light chamber. The light is then responsible for destroying the pathogen’s DNA cells by simply shining through the water passing through the unit. In summary, this process doesn’t involve any chemicals harmful to both our bodies and the environment.

3. Activated carbon filters

This water purification method is pretty miraculous when it comes to removing contaminants, bad taste, and odor from your home’s water. Therefore, how does it work? First and foremost, activated carbon filters are the granular or powdered block of carbon that is extremely porous. 
Just imagine a gram of activated carbon is equivalent to a surface area of 600 to 3600 sq yards. This means, 4 grams can be compared to a football pitch. It’s this massive surface area that makes this method very effective in absorbing/removing contaminants.

That said, when the water passes through actively charged carbon filters, the water impurities stick to the carbon hence, pure water output. However, the effectiveness is dependent on the temperature and flow of the water. Therefore, smaller carbon filters are best with cold water and low pressure.

In addition, activated carbon filters are classified according to the particle size they can remove. The sizes are measured in macrons ranging from 50-0.5 macrons. This means, the smaller the pore the more effective it is, but with reduced water flow.

4. Sediment filters

This is arguably one of the best whole house water filtration methods. Apart from that, this unit is budget friendly and also easy to install. It typically resembles a woven string or spun polypropylene and is selected according to particle size to be removed (for example 2-100 macrons). For your home, a small particle size filter with smaller pores is recommended. 

However, the smaller pores will require more pressure for water to pass through the filtering material. Also, if you have a bored or dug well, go for the finest filter available to effectively remove the fine clay particles that are often present in the water.


Did you learn something from this publication? Well, filtering your home’s water can be a simple and inexpensive process thanks to the variety of water filters. Also, before purchasing a water filter, always test the water so that you’re sure of what is to be removed. Use the services of a reputable or certified laboratory for water testing. Alternatively, use your nose to detect any objectionable odor. Feel free to leave us your valuable review in the comments section below.
