Why it's safe for your family

Solid hardwood sheds zero microplastics — unlike plastic boards, wood fibers are natural and biodegradable. Nothing synthetic enters your food.
Naturally antimicrobial maple — hard maple has natural properties that kill bacteria on contact. Cleaner than plastic over time.
NSF-certified commercial grade — meets the same standards used in professional restaurant kitchens.
No adhesives or coatings — solid single-piece construction with no glues, finishes, or synthetic materials.

Is this really plastic-free? Yes — and here's why

A cutting board sheds microplastics only if it is made of plastic — every slice scores the surface and releases particles into your food. This board is a single block of solid hard maple. There is no plastic in it to shed.

What to avoid instead

Plastic cutting boards are one of the most significant — and overlooked — sources of microplastic contamination in your kitchen. Every knife cut releases particles directly into your food.

Research finding

A 2023 study found that plastic cutting boards release 14–71 million microplastic particles annually from normal knife use. Every chop, slice, and dice scores the surface and sends plastic directly into your meals.

How we verify — and what we don't

Straight answer: we're a research team, not a testing lab. Here's exactly what our rating is based on — and what it isn't — so you can weigh it honestly.

What we check

What the product is made of, from the maker's own specs and product listing.
Whether any part that touches you or your food uses PTFE, PFAS, plastic, or a coating that can degrade.
Peer-reviewed research on how that material behaves when heated, scratched, washed, or worn.
Known failure modes — how the product actually breaks down in a real home.

What we don't do

We have not chemically tested this specific unit in a lab.
We don't take payment to rate a product higher — there is no sponsored placement.
We don't show star ratings or "trusted by thousands" counts we can't stand behind.

What gets a product rejected

Anything that adds a known microplastic, PFAS, or off-gassing source — a non-stick coating, a plastic surface against food or skin, vinyl/PVC — is downgraded or cut. We only list what clears that bar.

Common questions

How do I maintain it?

Simple: hand wash with warm soapy water, dry immediately, and oil monthly with food-grade mineral oil or board cream. That's it. With basic care, a John Boos board lasts 20+ years and actually looks better with age.

Can it go in the dishwasher?

No — the dishwasher's heat and prolonged water exposure will warp and crack any wood board. Hand washing takes 30 seconds and protects your investment. Just wash, dry, and you're done.

Does it harbor bacteria?

Actually, the opposite. Research from UC Davis found that wood cutting boards are safer than plastic ones. Bacteria get trapped in knife scars on plastic boards and multiply, while wood's natural fibers pull bacteria below the surface where they die. Hard maple is especially antimicrobial.
