Nadia Halvorsen

Editor, systems and water quality

Nadia edits the cost, systems and maintenance guides. She works from manufacturer spec sheets and NSF/ANSI listings, maintains the installed-price bands, and rewrites any page whose numbers cannot be traced to a document.

What she edits

The cost hub, the systems and maintenance guides, the problem guides and the equipment reviews. Prices are the installed bands she verifies each quarter; removal claims are checked against the certification listing for the specific model.

How a page is reviewed before it publishes

Every removal claim is traced to an NSF/ANSI listing or a manufacturer spec sheet. Cost examples are recalculated: five-year totals must reconcile with the stated consumables. Each problem guide names the test that proves the problem before recommending equipment.

What this site does not claim

We do not run a laboratory and we do not install every system we write about. Equipment pages reproduce published specifications and prices; they are not test results.

Contact the editor
