Water filters
Best Water Filter Pitchers
A filter pitcher is the lowest-effort way to improve tap water: fill the top, let gravity do the work, keep it in the fridge. The differences that matter are what the filter is certified to reduce, how long it lasts, and how much you'll pay in replacement cartridges.

Quick picks
We are still verifying product picks for drinking-water filters, and we only list products after an editor has checked them. Until then, here is how to build a shortlist that fits your home.
- Independent certification. Look for NSF/ANSI certification for the contaminants you care about: 42 covers taste and odor, 53 health-related contaminants such as lead, 58 reverse osmosis, 401 emerging compounds. A marketing claim is not a certification.
- Your water report. Check your utility's annual water quality report or run a lab test first, so you buy for the contaminants you actually have.
- Rated capacity and cost. Divide the cartridge price by its rated gallons to compare true running costs across models.
- Flow and fit. Check the flow rate and whether it fits your sink, counter or fridge shelf.

Carbon pitchers vs. multi-stage pitchers
Standard carbon pitcher filters are designed mainly to reduce chlorine taste and odor, and some also carry certification for specific contaminants such as lead or certain PFAS compounds — but only on the models that say so. Multi-stage designs add ion-exchange media to pull down total dissolved solids much further, at the cost of shorter filter life and slower filtering.
Neither type is a substitute for a water test if you have a specific concern. See our Brita vs ZeroWater comparison for how the two approaches differ in practice.
What to check before buying
- Certification, model by model: look for NSF/ANSI 42 (taste and odor), 53 (health effects such as lead) or 401 (emerging contaminants) on the exact filter you'll use — a brand's other filters may not carry the same claims.
- Cost per gallon: divide the cartridge price by its rated gallons. A cheap pitcher with short-lived filters can cost more over a year than a pricier one.
- Capacity and footprint: a 10-cup pitcher suits one or two people; larger households usually prefer a gravity dispenser that sits on the counter.
- Refill fit: confirm replacements are easy to find before you commit — see our replacement filter guide.
Frequently asked questions
Do water filter pitchers remove lead?
Only models whose filters are specifically certified for lead reduction (NSF/ANSI 53). Many basic carbon filters are certified for taste and odor only, so check the exact filter's certification sheet.
How often should I change a pitcher filter?
Follow the manufacturer's rated capacity — commonly a couple of months or a set number of gallons for standard carbon filters, and less for multi-stage filters used on harder water. A slowing flow rate is a common sign a filter is spent.
Is a pitcher enough, or do I need an under-sink system?
For improving taste and reducing chlorine, a pitcher is often enough. If you want broader contaminant reduction or filtered water on demand without refilling, an under-sink system is the step up — see our under-sink filter guide.
