Clean water is a non-negotiable. But between chlorine, PFAS, fluoride, and even microplastics, tap water quality isn’t always as safe as it seems. And with so many filters on the market — from pitchers to reverse osmosis systems — it’s hard to know what actually works.
So we tested and researched the best water filters of 2025 based on what matters: non-toxic materials, filtration power, durability, and user trust. Here’s what we found.
What to Look for in a Water Filter
Filters That Actually Remove Contaminants
Look for certifications like NSF/ANSI 42, 53, 58, and 401, which cover chlorine, lead, VOCs, fluoride, and microplastics.
BPA-Free & Safe Materials
Avoid plastic-heavy units with unclear materials. Opt for stainless steel, food-grade BPA-free plastics, and durable ceramic elements.
Long-Term Costs & Maintenance
A cheap filter that needs frequent replacements can cost more (and waste more) over time than a well-built system.

FAQ: Water Filters & Clean Drinking Water
What is the best filter for drinking water?
It depends on your needs — but countertop filters like Berkey or under-sink RO systems like APEC offer top-level protection.
Which is the best water filter to buy?
If you want the highest filtration, choose a reverse osmosis or gravity-based system. For everyday simplicity, opt for a pitcher or countertop model.
Which water filter removes the most contaminants in the world?
Multi-stage RO filters like APEC and Berkey systems with fluoride filters are top-tier.
What is the healthiest way to filter tap water?
Using a filter that removes contaminants while preserving essential minerals — or adding remineralization after RO.
Which filtration method is best for drinking water?
Reverse osmosis for maximum filtration; activated carbon for taste and chlorine.
What filter removes microplastics?
Filters with 0.2 micron or smaller elements, like LifeStraw, Epic Pure, or Berkey.
What are the disadvantages of drinking filtered water?
If over-filtered (like some RO systems), water may lack essential minerals. Also, filters must be replaced regularly to stay effective.
Is it better to filter tap water or drink bottled water?
Filtering tap water is often cleaner, cheaper, and better for the planet.
What water filter does not remove minerals?
Activated carbon filters usually retain minerals; RO systems remove them unless re-added.

No. Boiling does not remove microplastics or chemical contaminants.
Does LifeStraw remove microplastics?
Yes — LifeStraw filters remove microplastics and bacteria.
Is reverse osmosis good for you?
