Top 5 Best Whole House Water Filtration Systems

Water is an essential human need; as a matter of fact, clean water is recognized by the United Nations as a basic human right. Every person needs 20 to 50 liters of safe, clean water a day for drinking cleaning and cooking. While clean water is a necessity most well and tap water in America contains moderate to heavy levels of contamination from environmental and industrial pollution.

All sources of water contain some level of contamination. Contaminants can vary from naturally occurring minerals to man-made chemicals. The majorities of contaminant levels in the water are not high enough to cause immediate health problems but are more likely to cause chronic health problems; this means that effects will appear later following repeated exposure to small amounts of a contaminant.

While intake of the water might not cause immediate health problems, it is imperative that you look out for your health by using clean water. If you want to skip the article and view our top choice on Amazon…click here!

Types Of Whole House Filtration Systems

  • Heavy duty filtration system – this refers to the highest performing contaminant removal system due to the large amounts of filter media used. The media is placed in a tank and provides you with specific contaminant protection for up to 10 years before the media needs replacement.
  • Standard capacity water cartridge – the cartridges are placed in durable filter housings to treat contaminated water throughout the home. The filters are typically smaller compared to the heavy duty systems and require replacement every year.

Hydrogen sulfide in the water can also emit repulsive smells.

The Iron 300 is easy to maintain- there is no need for costly service and maintenance calls. What’s more? You get to protect your appliances from the damaging effects of manganese and iron.

The system features a 3 stage filtration process:

Stage 1 – the water is passed through a multi-gradient dual density filter that removes sediment and iron particles. This filter has 3 times the capacity of other filters. It also features a KDF core that inhibits the growth of bacteria and algae

Stage 2 – the second filter is an iron reduction cartridge that removes up to 3ppm ferrous iron i.e. clean water iron and manganese.

Stage 3 – this stage removes chemicals, hydrogen sulfide, chlorine and bad odor while improving on taste.

The Hydro Care Iron 300x is a great buy as it offers a lot more compared to others in the market such as the precipitation of clear iron to rust particles, reduction of water-soluble lead, mercury, chromium and copper and inhibits bacterial growth on the iron filter.

Whole house water filtering systems offer a number of perks within the home including:

  • Healthier showers and baths
  • Extended life of appliances that use water such as dishwashers, washing machines and household pipes
  • Softened water with showers that are scale free and spotless glasses
  • Brighter, softer and longer lasting clothing
  • Healthier skin and hair free of any contaminants from contaminated water

Installing a whole house water system can solve an array of problems affecting the quality taste or appearance of water. Whole house filtration systems eliminate contaminants from your water using a filter connected to your water line. All the water coming into your house will go through the filter before being directed to the toilets, appliances, and faucets in the house.

The types of contaminants that you will need to remove will vary based on where you receive your water from. Carbon filtration is effective in removing chloramines, chlorine ad odor to provide chemical free water in the entire home. If you have a specific contaminant, you will need a whole house system catered to removing the specific contaminant; for example, if you have brown and orange iron staining around your home, you will need a whole house iron filter.

A whole house softener does not work as a filter; it only works to soften hard water. A whole house softener is recommended only if you require soft water for spotless glassware or a scale free environment. A softener can also be combined with any whole house filtration system and work together to provide, soft and clean water throughout every faucet.

It can be difficult to determine the need for a water filtration system in your home and if yes, what system suits your home the best. Not all products in the market may be effective for the same group of contaminants; if you have identified a particular contaminant in your water use a contaminant selection guide to find products that are certified to reduce specific contaminants.

Home water filtration systems require constant maintenance to operate properly; ensure you are operating your unit in line with the directions provided by the manufacturer. Replace filter cartridges and membranes and other parts on a regular basis as recommended.

Before purchasing a whole house filtration system you have to consider:

  • Your water quality – so as to understand whether you will need a simple faucet filter or a whole house filter system
  • The contaminants – the type of filter will be determined by the type of contaminants in your water.

Whole house filters work better for removing rust, sediments, and scale. Tap-based filters work better for removing organic chemicals. By-products of chlorine and industrial solvents. In some instances, you might need to supplement your whole house filtration system with a tap filter for better tasting water.

Unfortunately, using both systems is not eco-friendly in terms of materials necessary to get your water cleaned but it is a better off alternative to bottled water which is costly.

In the long run, you will need to lean towards methods and systems that are National Sanitation Foundation, NSF tested as the NSF certifies filters on the basis of what contaminants they reduce.

Here is a review of the five best whole house water filtration systems.
