They are good for water cleaning before it gets into your various faucets and showers. They get rid of dangerous contaminants to ensure you get quality water. 

A good POE filtration system limits water hardness. It improves water smell and taste. You will get clean water for use, which will reduce negative effects on your hair and skin.

The buying process of a perfect whole house water filter

Households are different and thus will need a different and unique filtration system. To start, begin with assessing the type of water supplied in your house. Understand the components in your backyard well before buying a water filter. All water filters have the same basic functioning, but what they target to get rid of in water may differ. Do you want to have tasty, clean and fresh water, or you are targeting to remove a specific component? Many filtration systems will remove heavy metals, sediment, dirt, rust, odors and chlorine. 

Let’s look at the vital things to look for when buying a whole house water filter. 

Water flows

Many whole house water filtration systems will produce different water amounts. Gallons per minute (GPM) is the metric used to represent this water flow rate. All filtration systems have this metric specification in their systems ratings. 

The water treatment system filters out all contaminants in the house faucets. In your home, be keen on the house needs, especially the peak hour needs. Consider situations like mornings when everyone is in a hurry preparing to go to school or work. Don’t buy filtration systems that produce fewer gallons per minute. If the GPM metric doesn’t fit for houses with many members, don’t buy the product. The products with a low GPM metric works well for smaller households. 

Products with at least 10GPM metric fit all households, whether small or big. They will give a steady water flow without any water flow interruptions. 


Filters work to remove specific contaminant or a cluster of impurities. Carry out a home water analysis test to get the impurities present in the water. It will aid you to buy a unique filter that will eliminate those specific impurities. 

It will take you an hour or less to know whether the water has heavy metal impurities or microorganisms. It’s always good to buy a regular system with a copper-zinc filter. It will get rid of all these metals at once. If the water analysis shows that bacteria threaten your water, get a filter that gives UV filtration. Many filter manufacturers offer UV filters as an option. 

The common contaminants that need filtering out are sand, dust, rust and dirt. They are visible particles you can see with naked eyes. The visibility makes it possible to strain them out mechanically. When they are in large quantities, they will need a multi-stage filtration process. You can either use disposable or reusable filters to remove them. 

Chemicals are other impurities to remove from water. Carbon filtration removes all chemical contaminants in water, including chlorine. 

Iron is another impurity to remove from water. Ferrous and ferric iron contaminants are common in city water supplies. Sediment filters can remove rust and iron particles. Ion exchange or oxidation is vital in eliminating clean water iron. 

House consumption

If your house consumption is high, don’t buy a cheap filter. The filter will need frequent changing that ends up being more expensive. Filter longevity and water consumption are key factors. Consider them when purchasing the filtration system. 

Though filter needs low maintenance, they need changing. Check the longevity to know when exactly when to change. Some will need changing after hitting 100,000 water gallons per minute while others go up to one million.


Filters show the micron rating. Water analysis results will give the micron rating you need. Some filters have a one-to-five-micron rating, while others have a series of filters. The series may go up to the submicron level. They remove five-micron particles first, then go to the lower levels until water is pure. 


Now you can make a great decision basing on your needs. Choose the best whole house water filter to get rid of dirty water that will affect you.
