Plumbing — FAQ
What's the difference between under-sink and whole-house filters?
Under-sink filters treat water at a single tap for drinking and cooking, targeting chemicals like PFAS and lead. Whole-house filters install on your main water line, removing sediment and chlorine from all water including showers and laundry. Most homeowners combine both for complete protection.
How often should I replace my water filter?
Replace faucet filters every 2-3 months or 100 gallons. Under-sink cartridges typically last 6-12 months or 8,000 gallons. Whole-house sediment filters need changing every 3-6 months depending on water quality. The ICEPURE system extends this to 3 years with its 22,000-gallon capacity.
Do these filters remove beneficial minerals?
Most activated carbon and sediment filters retain healthy minerals like calcium and magnesium. Only reverse osmosis systems strip beneficial minerals. The Waterdrop 10UA, Purewell, and ICEPURE systems preserve mineral content while removing contaminants, improving taste without demineralizing.
Can I install these systems myself?
Faucet-mount filters require no tools. Under-sink systems need basic wrench skills and take 30 minutes. Whole-house housings with 1-inch NPT ports like the SimPure DB10P demand pipe cutting and soldering—DIYers comfortable with plumbing can handle it, but others should hire a professional.
What are PFAS and why do they matter?
PFAS are 'forever chemicals' linked to health risks that persist in water supplies. They're not regulated in many areas but are increasingly detected. The Waterdrop 10UA specifically targets these compounds, making it a future-proof choice as regulations tighten.
Are NSF certifications important?
NSF certifications verify manufacturer claims through independent testing. NSF/ANSI 42 covers taste/odor, 53 covers health contaminants, and 372 ensures lead-free components. Always prioritize certified systems like the Waterdrop 10UA and Purewell over uncertified alternatives.
