FAQs

1. Do whole house water filters need to be flushed?
Yes, most whole house water filters need to be flushed for 5-10 minutes when first installed to condition the filter media.

2. How often should whole house water filters be replaced?
Typical replacement intervals are 6-12 months, depending on water usage and quality. However, it’s important to monitor the filters and replace them when water flow or taste/odor begins to deteriorate.

3. Do whole house water filters reduce water pressure?
Quality whole house filters are designed to have minimal impact on water pressure, typically a reduction of less than 10 PSI. However, older or clogged filters can lead to more significant pressure drops.
