The Best Whole House Water Filter for Iron in 2021

The Best Whole House Water Filter for Iron in 2021

A whole house water filter treats and purifies the water that flows into your house through the main supply line. It gets rid of the contaminants that may be present from the supply point and ensures the water coming out of the faucet is safe to consume.

Investing in a good home water filtration system is therefore essential. The purification systems are often fitted with filters that help them achieve the purest liquid output. 

The following are some of the best whole house water filters on the market!

1. iSpring WGB22BM 2-Stage Whole House Water Filtration System

The iSpring WGB22BM 2-Stage Whole House Water Filter helps purify the water in the house. It removes sediments, harmful chemicals, excess iron, manganese, and microbes. 

During the first stage of filtration, the 5 microns polypropylene filter removes dirt and other particulate sediments. If these particles were to move past the first filter, they would clog the second filter.

In the second stage, coconut shell and CTO (chlorine, taste, odor) carbon filters filtrate the remaining contaminants in the water. The water is thereafter rendered safe for use.

Product Features

  • The system comes already assembled, so you can install it yourself following a manual. 
  • iSpring is factory-assembled from right to left. The bracket is detachable and you can switch.
  • The iSpring water filter system removes chlorine, industrial solvents, iron, herbicides, pesticides, sediments, bad odor, and other contaminants.
  • This unit does not soften your water, so it leaves the minerals intact. 
  • The total dissolved solids (TDS) remain intact in the water and keeping it healthy. 
  • The filtering system has a capacity of 100,000 gallons.
  • iSpring is equipped with a 1-inch outlet and a 2 gradient filtration system.


  • The iSpring 2-stage filter is a minimum maintenance device
  • Excellent filtering efficiency and capacity
  • It utilizes a large port that conducts large volumes of water to the filters per minute
  • The filter lasts a long time thanks to the compact fabrication technology of the coconut shell carbon filter
  • The iSpring 2-stage whole house filter has been independently tested and meets the NSF/ANSI standards. The tests prove that the filtration system eliminates at least 95% of contaminants. 


  • Upon connecting the joints, the water may leak. Reinforce it with Teflon as a precaution
  • This system will not soften hard water. You may have to add a reverse osmosis system for your drinking water.


A filter in the household water purification system works okay for a family of four for one year. However, it is recommended to replace after 6 months for better performance. 

Furthermore, install shut-off valves at the entry point and the outlet of the system. Once you do this, you won’t have to waste the water in the house by draining it when you want to replace filters.

This filter is worth it because it does not affect the water pressure in your house.

2. Aquasana EQ-WELL-UV-PRO-AST Whole House Well Water Filter System

Factors That Determine the Best Home Filtration Unit

Filters and Contaminants

Different filters eliminate different contaminants. You should test your water supply and buy the filter that works for the kind of contaminants present in the water.

Rate of Water Flow

Water filtration units allow different volumes of water to flow through every minute. The amount of water reaching the shower and faucet outlets will remain the same as your normal water output rates.

Rate of Water Consumption

The amount of water your household uses matters because if you went for a pocket-friendly filtration system while your house consumes a lot of water; you will be forced to change the filter more often. 

In the long run, your choice will provoke more costly. If, on the other hand, you invest in a system that is more expensive but can withstand your consumption needs, then you can change the filters less frequently. 


Filters with a micron rating of 0.35 are the best. You can also opt for 1 micron rated filters. The bottom line is to understand the types of sediment in your water supply. 


A good whole house water filtration system will produce clean, crispy tasting water. It also safeguards the health of your family since bacteria and viruses in the water supply are killed.
