Frequently Asked Questions
How fast will an activated carbon filter reduce odors?
You can notice reduced odor and improved taste within minutes to a few hours after installing an activated carbon filter in a pitcher or vent pad. Whole-house cartridges will usually show water taste improvement after flushing the new filter (a few gallons) and may take a short time to cycle through plumbing for full effect.
How do I know what size filter or vent pad fits my system?
Measure the cartridge or register opening before you buy. Common whole-house cartridge sizes include 2.5" x 10" and 4.5" x 10"; vent pads are often sold pre-cut (for example 4" x 10"). Also note the seal type—some housings require specific end caps—so check compatibility listings or keep your old cartridge as a reference.
How often should I replace filters before a gathering?
If you want maximum freshness, replace pitcher or vent filters within a month of hosting if they get heavy use; for whole-house carbon/KDF cartridges, a fresh cartridge within six months is typical but if your water has strong chlorine or sulfur odor, replacing shortly before an event can give the best immediate results.
