If you want a “best water filter” that actually matches your life, start with how you’ll use it (pitcher vs faucet vs under-sink vs RO). I focused on filters with verifiable third-party certifications and practical ownership costs (filter life, flow, install hassle).
Top picks
Aquasana AQ-5200 — Best for most kitchens (under-sink, high-certification)
A strong “set it and forget it” option with a dedicated filtered-water faucet and solid verified certifications.
Why it wins: Great balance of certification breadth + decent flow for everyday drinking/cooking.
- Transform Tap Water Into Clean Water - Reduces up to 99% of 78 contaminants including lead, PFAS (specifically PFOA and PFOS), chlorine, pesticides, & more while leaving healthy minerals. This system will NOT reduce Total Dissolved Solids (TDS)
- High Flow Rate - This system powers through a half-gallon of water every minute. No need to wait for clean water compared to traditional drip filters.
- Cost Efficient & Long Lasting - The most economical filter on the market at less than 10 cents per gallon filtered. Lasts for 6 months or 500 gallons before a replacement filter is needed.
Pros
-
Verified certifications to NSF/ANSI 42, 53, and 401 (via WQA testing/certification).
-
2-stage under-sink system keeps your main faucet pressure unchanged (uses its own tap).
-
Clear published performance data sheet (easier to trust than vague marketing).
Cons
-
Requires drilling/adding a small faucet (or using an existing hole).
-
Not a “zero wastewater” system like a simple carbon pitcher.
Trade-offs / who should skip
-
Skip if you rent and can’t add a faucet hole.
-
Skip if you need reverse osmosis specifically (this isn’t RO).

ZeroWater 7-Cup Pitcher — Best if you want very “low TDS” taste (and don’t mind more filter changes)
A pitcher that uses ion exchange aimed at stripping dissolved solids (including minerals).
Why it wins: Verified NSF certifications and the “clean slate” taste some people love—especially with hard water.
- Check Your TDS: The 7 Cup 5-Stage Ready-Read Water Filter Dispenser has a TDS Meter to check the levels of dissolved solids before dispensing or pouring water – always know when it is time to change your filter
- Advanced Filtration: Our 5-Stage Ion Exchange Filter removes virtually all dissolved solids (TDS) for the purest tasting water; Total Dissolved Solids are organic and inorganic materials, such as metals, minerals, salts, and ions dissolved in water.

Can noticeably reduce “hard water” taste (because it targets dissolved solids).
-
Includes a TDS meter in many kits (useful for monitoring).
Cons
-
Can remove minerals too—some people find the taste “flat.”
-
Filters can exhaust faster in high-TDS areas (more frequent replacements).
Trade-offs / who should skip
-
Skip if you specifically want to keep minerals in your water.
-
Skip if you don’t want to think about filter monitoring/replacement more often.
Scores: Performance 3/5 • Certified contaminant scope 3/5 • Ease of use 4/5 • Value 3/5

APEC markets it as WQA certified.
-
Great choice if you dislike any residual taste/odor many carbon filters leave.

More install complexity (tank + drain line) than standard under-sink filters.

RO systems produce wastewater during filtration (normal for this type).
Trade-offs / who should skip
-
Skip if you can’t install plumbing connections or you’re in a strict rental.
-
Certification scope note: I saw “WQA certified” on the maker page, but I couldn’t verify the exact NSF/ANSI standard coverage from a primary certification listing in my quick pass, so I treated the detailed certification scope as not verified.

FAQs
What’s the best water filter overall?
For most households, an under-sink system with strong verified certifications is the best balance of convenience, output, and trust—so I’d start with the Aquasana AQ-5200.
Is a faucet filter better than a pitcher?
If your faucet is compatible, a faucet filter is usually faster and more convenient. A pitcher is better if you want zero install and fridge storage.
Do I need reverse osmosis?
Only if you specifically want RO-style filtration and accept the trade-offs (install complexity and wastewater). For many people, a well-certified under-sink carbon system is plenty.
Did I check recalls?
I spot-checked official CPSC recall listings and only found an old Brita recall related to children’s water bottles (not pitcher/faucet/under-sink systems).
