How To Buy Your Best Whole House Water Filtration System
When selecting your best whole house water filtration system, there are a few features to look for in the filter and your plumbing system. Before buying your filtration system, the first thing to do is to understand what in your water needs filtration.
If you use city water, you can check from your municipality how they treat water. Once you understand the levels of chlorine, chloramine, and other chemicals in the water, you can buy a filter that can bring the levels down so your health won’t be affected.
If you use well water, it is best to get a filtration system that removes sediment, dirt, odors, smell, and more water contaminants. Other than your water condition, consider the following before you buy a whole house water filter.
a) Water flow
One best way to ensure you get the best whole house water filtration system for your house is by understanding the amount of water it can filter every minute. In application, the water passes through the filter before being distributed to the different faucets in your household.
When you buy the filtration system, you should see the manufacturer’s flow rate recommendation in GPM or gallons per minute. Pick a rate that would sufficiently supply water around the house, especially at pick hours when most appliances are running.
If you have several people in your house, any rate above 15 GPM could be sufficient. It can reach different showers, a dishwasher, and the laundry room without interrupting water flow. The water flow rate ranges between 10 to 40 GPM.
b) Type of filter
Before you buy a water filter for the whole house, it would be best to test your water to understand which elements you need to remove. While all units function to clean water, they come with different filters that remove certain elements.
However, regardless of whether you use city water or well water, some common contaminants are sediment, rust, dirt, and dust. To filter these, you will need a system that uses multi-stage filtration to remove even the finest particles.
If you only use municipal water, you will need carbon filtration to remove chlorine, chloramine, and more. Additionally, your city water will also contain iron and rust found in pipes, so your uni will also need to have a sediment filter.
c) Water Consumption
How much water your household consumes should also guide you to the best house water filter system. All filters have the maximum amount of water they can filter before they become ineffective. This information can be found not the manufacturer’s website and product description.
It is a feature that determines filter life and the kind of maintenance you need. When buying, pick the best whole house water filter that fits the water consumption in your household. This article reviewed one filtration system that filters up to 1 000 000 gallons of water, while another one can filter 95 000 gallons.
However, please note that your type of water affects the durability of a whole house water filter. If your water has too many contaminants, you will need to replace the filters more often.
