Frequently Asked Questions
How do I know which system is right for my home?
Assess your needs. Is it bacteria, chlorine, hard water, or a mix of concerns? Match your water issues with the system features to achieve the desired results.
What does “GPM” mean, and why is it important?
GPM stands for Gallons Per Minute. It shows how much water the filter can handle without reducing your water pressure. Pick one that matches your household size. Smaller homes can go lower, larger homes need bigger GPM ratings.
How often do I need to change the filters?
Filter life varies! Some last months; others, like the Aquasana, can go for years. Check product details for replacements.
Do these systems soften water?
Not all! The Aquaboon uses tech to reduce scale buildup, and it’s great if hard water is a problem.
Are these systems difficult to install?
Some are easier than others. For instance Big Blue is wall-mountable which simplifies set up. Consider professional assistance if you are unfamiliar with plumbing work.
