Frequently Asked Questions
How often should I replace my water filter?
Replacement frequency depends on the filter type and your water usage. Most refrigerator filters need replacement every 6 months or 200–300 gallons. Under-sink filters typically last 6–12 months. Whole-house sediment filters vary from 3–12 months. Pitcher filters (like Brita) need replacement every 2 months or 40 gallons. Track each filter's last replacement date in this log to stay on schedule.
What happens if I do not replace my water filter on schedule?
An overdue water filter becomes less effective at removing contaminants as the filter media saturates. In some cases, bacteria can colonize a clogged filter and actually degrade water quality. Reduced flow rate is often the first sign a filter is overdue. Replacing filters on schedule ensures consistent water quality and avoids the health risks associated with a saturated or degraded filter element.
How do I know what filter replacement my system uses?
Check the filter housing for a model number or part number, typically printed on the filter itself or on a label inside the filter housing. Cross-reference this number with the manufacturer's replacement filter. Many filters have universal replacements available at lower cost, check that the micron rating and contaminant certifications (NSF/ANSI standards) match the original before substituting.
