Choosing a water filtration system can feel overwhelming. There are whole home water filtration systems, kitchen systems and countertop or gravity fed systems, and it is not always clear where to begin. The good news is that you do not need to know everything. You just need to know what kind of coverage you want and what matters most for your household.
This guide is here to help simplify the process so you can feel confident about your next step.
Whole Home Systems
A whole home system, also called a point of entry system, treats all the water entering your home. Every shower, faucet, appliance and laundry load receives filtered water.
A whole home system is ideal if you want:
- Cleaner water for bathing, cooking and everyday use
- Reduced chlorine exposure on city water
- Reduction of metals and contaminants that affect the entire home
- Better performance and longer life for appliances
- Improved taste, smell and clarity throughout the house
Our recommended whole home solution is the PureSync Home Whole House System . It provides broad filtration for the entire home and pairs well with a dedicated kitchen system for complete coverage.
Under Sink Kitchen Systems
An under sink kitchen system focuses on the water you drink and cook with the most. This is where advanced contaminant reduction happens and where families see the biggest improvement in safety and taste.
A kitchen system is ideal if you want:
- The highest level of protection for drinking and cooking water
- Reduction of contaminants that whole home systems cannot fully address
- Cleaner water for children and daily hydration
- A healthier alternative to buying bottled water
Our most advanced kitchen system is the PureSync Undersink Filtration System . It offers the strongest targeted contaminant reduction in our lineup.
Countertop and Gravity Systems
Countertop and gravity systems sit on the counter or a stand and do not require installation. They use ceramic and carbon filtration to improve taste and reduce common contaminants, making them a practical option for many households.
These systems are a good option if you:
- Rent your home or move frequently
- Prefer filtration without modifying plumbing
- Want better tasting water on a lower budget
- Need a portable or backup filtration option

How These Systems Compare
- Whole home systems improve all water in the house and reduce contaminants that affect bathing, appliances and plumbing.
- Under sink kitchen systems provide the highest contaminant reduction for drinking and cooking water.
- Countertop and gravity systems offer convenience and accessible filtration without installation.
Many families choose both a whole home system and a kitchen system because each addresses different needs and they complement one another.
Questions To Help You Decide
- Am I most concerned about the water my family drinks
- Do I also want to improve shower and bath water
- Do I want an installed system or something portable
- Are there specific contaminants I am worried about
- Have I had my water tested recently
If drinking water is your focus, start with a kitchen system. If you want better water throughout the home, begin with a whole home system. If you want a simple, portable solution, consider a countertop or gravity system.
