These are all things you can learn in this guide to purchasing a water filter system.

1. Learn About Whole House Water Filtration Systems

Make sure you understand what a whole house water filter system is before you go shopping for one.

Whole house water filters are installed at the spot where your main water line enters your house. Therefore, the whole house's supply of water is treated before it ever gets to the hot water heater, faucet, showerhead or your washing machine.

Because it treats everything right at the source, you only need one system.

2. Determine Which Chemicals You Need to Filter Out

Before you can choose a system, you'll need to know what it is you're trying to filter out. Start by getting a water quality report from your town or city's water department. If you use well water, you'll need to do the test yourself or hire someone from a lab.

You'll be looking for amounts of heavy metals, such as lead, copper, and zinc. In addition to heavy metals, you need to know if your water contains chlorine, chloramine or dangerous contaminants like pesticides and arsenic. You can look here to find a complete list of water contaminants and their safe levels.

3. Check Your Flow Rate for Faucets and Appliances

How much water can flow through your house and to your faucets and appliances is called flow rate. It is measured in gallons per minute.

You need to know the flow rate to choose a system that can keep up with the demands of water usage in your house. If you have a large family or a lot of water usage, you'll need to pick a higher flow rated system.

4. Choose a Type of Water Filtration System

There are three types of water treatment systems you can choose from. Carbon-based, reverse osmosis or Next Generation.

Carbon-based is the most affordable of all three water filter systems. It works like those water filter pitchers. It basically has a carbon filter that allows the water to pass through but picks out the contaminants.

The best carbon systems have a 3 stage filtration process that presifts for large contaminants, a copper and zinc filter that removes chlorine and heavy metals, and then finally uses activated carbon to filter for organic contamination.

Reverse Osmosis filtration can be quite costly, but it does a much better job of filtering your water. They require large tanks of water to work by forcing it back through a membrane to filter. Unfortunately, this process can create a large amount of wastewater.

Next Generation filtering is just as effective as Reverse Osmosis, but the system takes up much less space in your home. It also produces far less wastewater.

The Next Generation system has a higher capacity than traditional carbon-based filtration systems. It uses super pure granule style carbon filters that are more effective at removing contaminants.

5. Determine What Size Water Filter You Need

A larger filter is definitely better when it comes to your whole house water filtration system. The larger the filter, the more water it can handle at a time. Larger filters also allow you to go longer between replacements.

You should get a system with the largest filter you can afford.

6. Consider Where to Put It In Your House

Since a whole house water filter needs to be installed at the point where your water enters the house, your choices can be limited. Systems with a larger footprint, like the reverse osmosis, may be difficult to install in certain spots. Consider how much space you have available when you purchase a system.

It's a good idea to find the point of entry for your water main, and measure the space around it. Use this to help narrow down your water filter choices.

7. Look at Maintenance Requirements

Whole house water filter systems will require you to change the filters. Some systems include a Consider the cost of replacement filters when looking to purchase your system.

8. Check for NSF Certification

NSF Certification means your water filter system has been tested and approved for use according to public health standards. Do not buy a system that is not NSF Certified. You can read more about NSF Certifications here.

9. Get Recommendations

The best way to find a good system is to ask around. Check with friends, family and coworkers to find out which systems work the best or which ones to avoid. You can also see if your local water department has recommendations.

Keep your own requirements in mind when reviewing recommendations. A system that works for your friend with a much smaller house may not be the best one for you. However, the brand is worth considering.

10. Research Reviews and Reach Out to Vendors

Once you've decided on a type of filter and gotten some recommendations, it's time to research a little further. You don't want to purchase a water filtration system without checking into reviews.

You've checked your water and done the research. Now, you can place your order for a home water filter with confidence!
