Do you know what’s important before picking a water filter? Check out these important factors:

More than one Filter for Purification

You must not buy a well water filter before testing your water. A water quality test identifies all the contaminants in water and helps select the filter as per your filtration needs. Since most whole house filters come upwards of $500, it is wise to get your water tested and select an appropriate filtration system.

This way, you can install a specialist filter to remove a particular contaminant with a certain concentration. For example, many well water filters can remove iron, but only a few can remove iron above 6 PPM. Similarly, you can check this for all contaminants.

Depending on water quality, you may also need to install more than one filter. Most people go for a sediment filter, a water softener, and a whole house filter (based on contaminants).

Filter Type

The next important thing to consider is the filter type. You can select one from cartridge-based filters (one or multiple), water softeners, iron filters, sediment filters, and UV filters. Each filter works differently and removes a particular set of contaminants. 

Filter Life

Filter life means the time before you need to replace the cartridges. Some will need replacement every 2-3 months, some require replacement every 4-6 months, and some have a life of 9-12 months. Some high-quality whole house water filters for well water could last for 5-10 years.

Some manufacturers also express filter life in gallons. This helps you calculate a filter’s life based on your daily consumption.

The important thing to consider here is that these are estimated values. The actual life of a filter depends on water quality and usage.

Flow Rate

Flow rate means how much water can be used at one time or the speed at which water leaves your filter. This is important as a slow flow rate can frustrate you with low-pressure water.

Whole house well water filters have a flow rate between 7-25 gallons per minute. An average home with 2-3 bathrooms and 4-5 people needs a 10-20 GPM flow rate. Some people like fast water from taps and prefer filters with a fast flow rate.

Installation & Maintenance

Some whole house water filters are easier to install compared to others. You have to cut the main water pipe, connect the filter and then connect the main water pipe to the other side. Most filters can be DIY installed if you know how plumbing connections work.

Some complex units require multiple valve installation, pressure buttons, and drain valves. We recommend you hire a professional plumber to install such filters.

All water filters require periodic maintenance. You’ll have to notice leaks, keep the filter clean and replace cartridges according to your system’s lifespan. Make sure you get a unit that has easy and convenient filtration.


Cost is a two-dimensional factor for water filters. You’ll have to pay the upfront price and then buy replacement cartridges periodically. So don’t forget to check replacement costs before buying a water filter.

Extra Features

Some whole house filters have extra features like filter replacement reminders, pressure gauges, pressure relief buttons, and bypass valves. These features don’t enhance the filtration capabilities of your filter, but they make the system user-friendly.

Warranty and Certifications

Warranty and certifications add value to your purchase. These features show that the manufacturer is confident about its product and gets it tested by third-party organizations to ensure that it works optimally under pressure and in the long run.

Frequently Asked Questions

1. Is a whole house well water filter worth it?

Yes. Whole house water filtration systems filter water at the point when it enters your home. It ensures that all your taps, appliances, and plumbing fixtures receive filtered water. This helps extend the appliances’ life and keep them scale-free. Moreover, whole house filters also make water fit for drinking.

2. Where should I install a whole house water filter for well water?

A whole house water filter must be installed where water enters your home. It is typically installed after a sediment filter and before the point where water lines divide.

3. Can a whole house water filter make water soft?

Not all water filters make water soft. Some water filters come with a built-in water softener that conditions well water. A few water softeners can remove iron and manganese from well water.

4. How can I maintain a whole house water filtration system?

Each unit has different maintenance needs. The typical maintenance needs include filter replacement, checking for leaks, and ensuring that filters stay away from direct sunlight and rain.

5. Can a whole house water filter remove water minerals and TDS?

Most whole house water filters don’t remove minerals and TDS. Water minerals such as calcium and magnesium are removed using a water softener, while a reverse osmosis system removes TDS.

6. Can I install a reverse osmosis water filter for the whole house?

Yes, you can, but these units are big, costly, and difficult to maintain. RO systems are more suited for point-of-use applications such as kitchen sink.
