How it Works
whole home filtration considerations
Many whole water filtration systems are sized based on the number of bathrooms in your home. Some filtration systems are designed to accommodate homes with 1-3 bathrooms, while others are built to treat homes with 4-6 bathrooms. Knowing the number of bathrooms in your home is usually a quick, easy way to help narrow down your choices and determine the best size for your house.
Flow rate is the amount of water able to flow through your water dispensers such as faucets, showers, dishwashers, and toilets. It’s important to know the flow rate of your dispensers because if it’s lower than the water filter’s flow rate, there’s a chance of leaking and burst hoses. On the other hand, if the flow rate is higher than the water filter’s flow rate, the water flow may be too weak, potentially causing choking due to air filling. You can calculate the flow rate of your dispensers by yourself.
Every home is different, especially when it comes to water problems. Your house’s water supply may come from a well, which can present challenges such as water hardness due to groundwater flowing through or over limestone. Or perhaps you get water from your city’s supply, which can be brimming with chlorine that causes your water to taste and smell foul.
These are just some examples of why you may need a whole house water filtration system. Take time to examine your water supply and see if you come across any of these common water issues:
- Discolored, orange, or red water and staining
- Blue or green staining
- Sediment or debris, including salts, soil, and micro rocks
- Rotten egg smell
- Metallic taste
- Yellow staining on kitchenware
- Clogged pipelines
- Rusting faucets
- Patches on bathroom and toilet floors
Whenever you’re looking for a whole house water filtration system, ensure that it’s certified by the National Sanitation Foundation (NSF). When you purchase an NSF-certified product, it means:
- Only FDA-approved raw materials were used to make it
- It passed numerous tests for material safety, design, construction, and performance
