What You Need To Know About Water Filtration Systems | Maryville, TN

Water filtration systems are becoming increasingly important to maintaining a healthy lifestyle. Our water supply is tainted with chemicals that could be harmful to human health. There are a wide variety of water purification systems in the market. We have compiled this guide to help you choose the best water filtration system for your Maryville, TN home.

Choosing the Best Water Filter

POU vs POE Systems

Water filtration systems can be roughly divided into two categories. Point of entry filtration systems (POE) filter water as it enters your home. This system will filter all water that passes via bathtubs, sinks, washing machines, showers, spigots, and other fixtures.

POU filters or point-of-use systems filter water where it is used, and you can choose where you need it. If you only want to filter the water you use for drinking and cooking, a filter that fits under your sink could be an option.

Contaminants You Want to Filter Out

Find out what’s in your water supply to pick the best water filter for your home. Identifying the compounds in your water supply is crucial in figuring out how to purify it. If you get your water from the city, you can regularly ask for updates on the water’s chemical composition. There are numerous low-cost water testing tools available to get accurate reports if you are getting water from a private source such as a private supply, river, or well. Alternatively, you can engage a water specialist to do the job for you.

Check the Flow Rate of Your Faucets and Dispensers

Water pressure issues arise when consumers purchase water filters without determining the flow rates of their faucets. The likelihood of a hose bursting or leaking increases if the hose’s flow rate is less than the water filter’s. However, if the water filter has a lower flow rate than the faucets and hoses, the water flow will be minimal, which could lead to repeated choking from air filling the system. Filter cartridges are affected by the varying flow rates of faucets and water filters, reducing their efficiency and effectiveness. The average water filter should have a flow rate that is 1-2 gallons per minute (GPM) higher than the average of your home’s faucets.


Water filtration systems should be NSF-certified. NSF has been entrusted by ANSI, the American National Standards Institute, to uphold quality standards across the board for the water filtration solutions it offers. The filter’s certification status is important regardless of its size. All our water filters are NSF-certified, so you need not be worried.


The cost of a water filter may vary depending on its specific characteristics, design, technology, output, etc. Some variants cost less than $30, while more expensive, high-tech systems might cost thousands of dollars. Likewise, you must consider how easy it is to perform routine maintenance, such as changing the filter cartridges. That’s why it’s important to consider the cost.

Filter Technologies

Several water filter technologies are currently available, each with its own advantages and disadvantages.

Activated Carbon

Activated carbon water filtration systems feature different types of natural carbon materials. Typically porous, these materials attract contaminants, causing them to stick to their surface. When choosing a filtration system, it is critical to consider the carbon’s efficiency.

Some water filters can only eliminate chlorine, unpleasant odors, and tastes, while others can eliminate radon and VOCs. Furthermore, activated carbon systems will not work for inorganic chemicals such as heavy metals, chromium, fluoride, and arsenic.


Ceramic filters feature small holes that allow water to pass through while filtering out all other pollutants. These only keep protozoa and bacteria out, not viruses or chemicals.

Reverse Osmosis

Water is pushed through a semipermeable membrane in reverse osmosis filters. Anything bigger than water molecules is effectively filtered out. These membranes effectively prevent the passage of viruses, nitrate, lead, bacteria, arsenic, and protozoa.

Unfortunately, these filters are ineffective against chlorine, trihalomethanes, and VOCs. The best household water filtration systems typically include activated carbon and reverse osmosis filters.


Distillation involves heating water to its boiling point and collecting the resulting steam, which contains none of the impurities. The boiling process destroys any biological impurities, such as bacteria and viruses. However, as most VOCs have a boiling point higher than water, distillation is not an option. Most distillation systems, however, have carbon filters that remove impurities and leave only H2O.

Types of Filtration Systems

There are several types of water filtration systems to consider for your Maryville, TN home.

The Faucet Mount Water Filter

Most of these filters feature activated carbon filters, and they attach to the end of the sink’s faucet. They can be set up quickly and cheaply and provide filtered and unfiltered water at the flip of a button. The downsides include that they might not fit all faucets, might make water flow slower, and might need replacing more frequently.

Countertop Filters

These are similarly attached to the sink’s faucet, but the system is placed on the counter nearby. While some are rather basic, using only activated carbon, others can be quite complex, incorporating many filters. These are simple to set up, last longer than faucet filters, and allow you to change from filtered to unfiltered water.

Gravity Water Filters

These counter filters require manual filling and work with activated carbon or ceramic water filtration systems. They’re available in various sizes, don’t need any special setup, and function with any water type. On the downside, they are cumbersome and need additional counter space.

Under-Sink Filters

Under-sink filtration systems are installed under a sink and deliver water through a pipe to the filter’s faucet. Under-sink filters filter enormous quantities of water and do not occupy counter space. The downside is they are sometimes costly and may require plumbing adjustments.

Whole House Systems

Whole-house filtration systems purify not only the water used for drinking but all the water that comes into the house. All the water that comes into your house is treated, which may be important in the case of volatile organic compounds (VOCs) and hard water. On the other hand, they are typically pricey and may require adjustments to the plumbing.
