Before selecting the whole house water filter for your house, there are few things that you must look at. So what are those factors that need your consideration? Take a look.
No of Stages/ Filters
The first thing that you must look in is the number of stages it features. It is good to have a 3-stage filter system because these systems are responsible for removing most of the contaminants from the water up to a great extent. Also, it depends on the type of filters a system uses. Most of the systems come with Sediment and Carbon filters. Also, some filters have three to four layers that provide great filtration.
So, it all depends on your needs and the type of water you are getting. If you only want to get rid of chlorine, sand, and rust, then you can go for two-stage filtration systems. But if other different harmful impurities are coming to your way, then the three-stage filter is a must.
The flow rate of the filtration system also must be considered. It is ideal to have a system that can offer 10 to 40 gallons of water per minute. The higher the flow rate, the better it will be for you. The size of the filters also plays a vital role in the flow rate. So, make sure the size is decent enough.
Life of the filter
Filters having higher life span are ideal to buy. It saves your time and money as well. But the replacement cycle depends on various factors such as the flow rate, type of filter, and the amount and type of contaminants present in the tap water.
It is also essential to look at the micron rating of the filter. Many filters can block particles larger than 1 micron which make them effective. But there are also some top-notch filters that can block any impurity larger than 0.35 microns which makes them far more superior as compared to those having 1-micron capacity.
So, it depends on the contamination present in your water. If it is highly contaminated, then it is recommended to go for those that can block anything more substantial than 0.35 microns.
Installation and filter replacement
Always try to buy those whole house filtration systems that are easy to install. You may ask a plumber to fix it, but if a filter system comes with clear instructions, then it is quite possible to install the unit by yourself. Also, make sure that the cartridges are easy to replace.

The next thing is to switch off the main supply line so that you can start installing your product. Also, never forget to drain the system.
Cut the available pipe
