Water & Air

Five filtration systems with exact models, filters and operating conditions. Performance claims stay tied to the evidence that supports them.

5 considered choices

How to choose ↓

Ingredient approval and testing are separate. Read the evidence note for the exact product you choose.

A little guidance

How to choose

Choose the setup that fits your home: a pitcher, countertop unit, under-sink system or air purifier. Match the exact model and original filters, and account for replacement parts. Keep AirDoctor’s ionizer off; follow the water system’s feed-water limits.

What we look for

Disclosed filter media, model-specific data, named replacement parts and clear operating and replacement instructions.

Testing and evidence

Certifications apply to named claims and configurations. Broader laboratory testing and maximum reduction figures are described separately from certified or universal results.

Can I use a cheaper third-party replacement filter?

The recorded approval does not cover an unreviewed replacement. A different filter can change the materials and performance evidence.
