Filter Type
The right filter type depends on your specific needs. Pitcher filters are great for small households on a budget.
Faucet-mount filters offer convenience without installation. Under-sink and reverse osmosis systems provide the most thorough purification.
Whole-house systems filter every tap in your home.
Contaminant Removal
Check which contaminants a filter removes. Carbon filters handle chlorine and taste issues.
Reverse osmosis removes the widest range of contaminants. Gravity-fed systems like the Big Berkey purify bacteria and cysts.
Look for NSF certifications to verify manufacturer claims.
Capacity and Filter Life
Filter life varies dramatically. Pitcher filters last 2-6 months, faucet-mount filters handle around 200 gallons, and whole-house systems can process 100,000 gallons.
Longer-lasting filters cost more upfront but save money over time.
Household Size
Match the filter to your household. Pitcher filters work for 1-3 people.
Faucet-mount and countertop filters suit families of 3-4. Whole-house and reverse osmosis systems serve families of 4-6 people comfortably.
Installation Complexity
Pitcher and faucet-mount filters need no tools or plumbing knowledge. Under-sink and reverse osmosis systems require drilling and basic plumbing.
Whole-house systems may need professional installation depending on your comfort level.
Frequently Asked Questions
The good ones tackle chlorine, lead, mercury, fluoride, bacteria, cysts, pesticides, herbicides, and sediment. What gets removed depends on the filter type — RO systems handle the broadest range of contaminants, while carbon filters are best for chlorine, taste, and odor.
It really comes down to your household. Pitchers are perfect for one or two people. Under-sink or countertop models suit larger families. If you want every faucet covered, go whole-house. And RO gives you the most thorough cleaning, though it costs more upfront.

In almost every way, yes. They cost pennies per gallon instead of dollars, they slash plastic waste, and many filters actually provide better filtration than what you'd get from a typical bottle. It's one of those rare upgrades that saves money and is better for the environment.
