Frequently Asked Questions
What are the Benefits of a Whole House Water Filter?
- Clean and chlorine free showers
- Improved water quality from every tap throughout the home
- Better tasting and smelling water
- Healthier skin, scalp, and hair
- Protection for plumbing and appliances
- Less build up on shower glass
- Cost saving over time by preventing scale buildup and protecting appliances

- Environmental benefits due to less reliance on bottled water
Why are pressure gauges important in a whole house water filter?
By tracking pressure changes, they help detect when filters become clogged or need replacement, ensuring optimal water flow and protecting plumbing and appliances from potential damage due to high pressure.
Can a whole house water filter remove fluoride?
Removing fluoride requires specialised media, like activated alumina or reverse osmosis, which need extended contact time. Home water filtration systems are designed for high flow rates to supply water to multiple outlets simultaneously, which doesn’t allow for the slow, thorough process needed for fluoride removal. Including a fluoride water filter in a whole house system would significantly reduce water flow and pressure, making it impractical for whole-home use. For effective fluoride removal a point-of-use fluoride water filter is recommended.Â
Can a whole house water filter remove PFAS?
Yes, our Triple Whole House High Flow 20″ Filter with S/S Bracket – Sediment, Carbon & Aragon for Town Water is tested and certified to remove PFAS from water. Â
Some whole house water filters with activated carbon may reduce PFAS levels to some extend and they can be coupled with a point of use PFAS water filter. Â
Do you lose water pressure with a whole house water filter?
A properly sized and installed household water filtration system should have minimal impact on your water pressure. Modern whole house water filtration systems are designed to maintain strong water flow while effectively removing contaminants. However, water pressure can decrease if filters become clogged. To maintain optimal pressure, ensure regular filter changes and choose the right size system for your home’s water usage. Our 20″ house water filter systems are specifically designed to provide excellent filtration while maintaining strong water pressure.Â
How do I choose the best location for a whole house water filter in my home?
When selecting the ideal location for your whole house water filter, consider the following:
Proximity to the Main Water Line: Install the filter near the main water shut-off valve, typically where the water line enters your home, to ensure it treats all incoming water.
Controlled Environment: Choose a conditioned, temperature-controlled space to prevent freezing and protect the filter from extreme temperatures, direct sunlight, and wild weather conditions (cyclones).
Accessibility: Ensure the location allows for easy maintenance and filter changes. A basement, utility room, or utility closet on the outer wall of your house can be ideal.
Safe and Secure Placement: Mount the filter on a sturdy wall or floor joist, away from electrical appliances or areas prone to water damage. If outside, secure it within a fenced area for added safety.
Installation Tips: Position the filter after the main shut-off valve but before the plumbing branches to other parts of the house. A horizontal section of pipe is ideal, but you can also use a “tee off” from a vertical pipe if necessary. Allow enough space for any pre-filters or additional components.
Space Requirements: Standard Big Blue filters may require approximately 20 inches in height, plus room for any pre-filters and clearance for maintenance. Total vertical clearance of approximately 25-26 inches is recommended.
What Are the Benefits of Installing a Bypass Valve?
A bypass is a plumbing feature that allows water to flow around a whole house water filter. It lets you divert water away from the filter, providing unfiltered water for maintenance, repairs, or specific tasks without interrupting the supply to your home.
Having a bypass is essential for several reasons: it simplifies filter changes, allows unfiltered water use for tasks like filling pools, and ensures access to water during emergencies if the filter fails. Overall, a bypass enhances convenience by allowing easy switching between filtered and unfiltered water while extending the life of your filter cartridges.
