There are several types of water filter filtration systems available, each with its own unique technology and benefits. Activated carbon filtration is a popular choice for removing chlorine, lead, and other impurities from water.
Activated carbon is made from charcoal and has a high surface area that allows it to trap impurities. It's often used in combination with other filtration methods to provide comprehensive water purification.
Reverse osmosis (RO) systems use a semipermeable membrane to remove impurities from water by applying pressure to force the water through the membrane. This method is effective for removing dissolved solids and other contaminants.
Distillation is another type of filtration system that involves boiling the water and then collecting the condensed steam, which is free from many impurities. This method is often used for removing heavy metals and other inorganic compounds.

Water Filter Types
There are several types of whole house water filter systems available, each designed to address specific water quality issues. The Ultimate Protection system, for example, is a comprehensive solution that removes major impurities from your water supply.
You can choose from different filter types, such as the Heavy Metals system, which targets heavy metal problems at your main water line, or the Anti-Scale system, which effectively improves your water experience by reducing water buildup in your pipeline and appliances.
Some common filter technologies include activated carbon filters, which are less effective at removing certain contaminants like nitrate and perchlorate. Other filters can reduce levels of contaminants like lead, disinfection by-products, and volatile organic compounds, or VOCs.
Here are some common filter types and their functions:
These filter types can be a good starting point in choosing the right water filter for your home.
Ion Exchange
Ion Exchange is a type of water filter that can soften hard water. It has its pros and cons, though. Softens hard water is a big plus, but it doesn't remove all contaminants.
The effectiveness of Ion Exchange depends on the size of its pores and the substances it's trying to remove. If the pores are too big, the filter won't be able to catch smaller contaminants.

Overview of Technologies
There are two primary technologies used in water filter products: carbon filtration and reverse osmosis. Both can be effective at removing contaminants, but they work in different ways.
Some water filters are certified to reduce chlorine from water treatment, which can improve taste and odor. Others can remove more contaminants, such as lead, disinfection by-products, and volatile organic compounds (VOCs).
Activated carbon filters are less effective at removing certain contaminants, like nitrate, perchlorate, and 1,4 dioxane. This is something to keep in mind when choosing a filter.
The effectiveness of a filter depends on several factors, including the size of its pores, the size of the substance it's trying to remove, and the electric charge of the substance. This is why different filters can remove different types of contaminants.
Here's a breakdown of the factors that affect what a filter can remove:
How It Works
Our whole home water filtration systems use a three-stage process to remove unwanted particles for better-tasting water. This process is like tiny magnets grabbing impurities from your water.
The first stage of this process involves removing large particles from the water. Imagine pouring a glass of murky water into a clear glass - the first stage of filtration would make it look just like that.
The second stage of the process works to remove even smaller impurities, leaving your water tasting fresher and cleaner. This is where the magic of filtration really starts to happen.
The third and final stage of the process is where the water is polished to perfection, removing any remaining impurities and leaving you with great-tasting water.

Removing Germs
Removing germs is crucial for keeping your water clean and safe to drink. Check to make sure the pore size of your filter is small enough to remove the type of germ you're concerned about.
Parasites and amebas are larger than bacteria, which are larger than viruses. This means you'll need a filter with a smaller pore size to catch these smaller germs.
To give you a better idea, consider the size of a typical filter compared to the size of the germ you're trying to remove. A filter with a smaller pore size will be more effective at removing smaller germs.
