Things to Consider in a Whole House Water Filter

1. Water Supply Source

The first thing to take into account is the source of your water supply. Does it come from a well or the city? Do you have issues on rust or sediments in the water? Does the water have a strange odor or chlorine taste? Are there issues with pesticide or herbicide runoffs?

The answers to these questions allow you to know the contaminants you want to remove. This allows you to find the most suitable water filter rather than simply looking for one with the least or most number of features.

2. Filtration Level

After taking into account the water supply, you have to consider the filtration level you want in the water filter. Filtration level is measured in microns. House water filters have different micron ratings.

A portable water filter used in camping situations normally has a filtration level of 0.1 micron. This is necessary since the water source is raw and contains a good amount of contaminants. These contaminants include mercury, Cryptosporidium, Giardia, and Volatile Organic Compounds or VOCs.

Whole house filters normally have a filtration level of five microns. This level is lower since the water supply has passed through a treatment facility. In addition, water flow will be slower if the filtration level goes down to a sub-micron level. The standard water flow of the filters on this list is 10 gallons per minute. A flow rate of 0.5 gallons per minute is already fast for whole house filters with a filtration level of 0.1 micron.

This simply means that at least two filters are needed if you want to remove all contaminants in your supply of drinking water. In this situation, you would need a faucet filter in all faucets in the house aside from the whole house filter system. The whole house filter can work on the water supply for the toilet, water heater, and washing machine, among others. These may not require an extremely clean water supply. But, your drinking water should be free of contaminants.

In the end, it is better to have more filtration stages you have for your water supply. But, you should consider the way each filtration stage works. It is also important to know what these stages do. Numerous filtration stages normally filter out smaller particles as water flows from one filter to another. This is considered an effective way of getting a clean supply of water. But, there are instances when one filtration stage is better than several stages of filtration. This will depend on the filter used. The main thing is not to focus on getting the biggest number of filtration stages. In this situation, you should look into what the filter offers and what it can remove.

3. Other Costs

A good price for a filtration is useless if it is necessary to change the filter each and every month. You should take into account the whole year cost of replacing the filter. In addition, many of these filters should be installed by a professional plumber. While you can install it yourself, it may be necessary for you to have some experience in doing this. You should also be prepared to pay for possible emergency expenses. But, its best for your neighborhood plumber to install it for you.

Which Whole House Water Filter do we recommend?

If we are to select the one we like, it would be the two-stage filter from Home Master.

There are three reasons why we selected this particular filtration system. Its one-micron filtration level is the first reason. It is capable of removing a good amount of contaminants in the water. Another reason is its simplicity. You just check any water issues you are experiencing and select the most suitable filter. The last reason is it offers a fast flow of water. Its flow rate is at ten gallons per minute. This filtration system also offers an extended filter life.

The other filtration system options are also good. For instance, the Watts system is affordable and expandable. But, many consumers may not have the patience to work on expanding their filtration system. The filtration system from Aquasana is also great. But, if users are not looking for soft water without using a liquid softener, the million gallon capacity may not be practical. On the other hand, the 3M system is also great to use, but a pre-filter is necessary to ensure optimum performance for the unit.

These are the top four filtration systems for the whole house. They offer different features meeting several needs of households. But, they all have the same goal of providing fresh and clean water. Check these reviews and select the one most suitable for your needs.
