Why this site exists

Manufacturer specs are useful. The ceiling tells the whole story.

Airwise is run by an experienced home-performance contractor who has installed numerous Panasonic bathroom fans and believes homeowners deserve clearer information than a carton can provide.

Experience, translated

A bathroom fan sits at the intersection of moisture control, indoor air quality, electrical work, duct design, and the building enclosure. That is why our reviews look beyond stated CFM and sones to the decisions that determine real performance.

How we work

We combine field observations, current manufacturer documentation, practical building science, and direct comparisons. We distinguish verified specifications from judgment, avoid fake prices, and update pages as models evolve.

How the site earns money

Some purchase links may be affiliate links. If you buy after using one, the site may receive a commission at no additional cost to you. Affiliate relationships do not purchase rankings or favorable conclusions.

Editorial promise: The recommended fan should fit the home and the use case—even when that means recommending fewer features or telling a reader to fix the duct first.

Our methodology

Three principles guide every page.

01 · Evidence

Verify the facts

Specifications come from current source documents, not recycled retailer copy.

02 · Context

Explain the system

A fan, duct, control, room, and enclosure work together. Reviews should too.

03 · Independence

Say what is not right

Every honest review includes tradeoffs and who should choose something else.
