Affiliate disclosure

Fri, 11 Sep 2026 00:00:00 +0000

OwnerSpec earns commission on some of the links on this site. If you click one and buy something, the merchant pays us a percentage. You pay exactly the same price either way.

This disclosure exists because the US Federal Trade Commission requires it (16 CFR Part 255), because the Amazon Associates Operating Agreement requires it, and because you cannot judge a recommendation without knowing how the person making it gets paid.

Cookie policy

Fri, 11 Sep 2026 00:00:00 +0000

This page lists everything OwnerSpec stores on your device. It is the detail behind the banner; the wider picture is in our privacy policy.

Nothing optional loads before you decide. Analytics scripts are injected only after a yes. Before that, no Google or Microsoft cookie exists on your device.
Reject is one click, in the same place as Accept. Refusing costs you nothing and the site is fully usable.
You can change your mind at any time with the “Cookie settings” link in the footer of every page. Choosing “Reject” there also deletes the analytics cookies already set.
If you are in the EEA, the UK or Switzerland, we ask before anything loads. Elsewhere, analytics start with notice and a standing opt-out, which is what local law requires there.
If we cannot tell where you are, we ask. Failure always defaults to the stricter option.

Strictly necessary

These are required for the site to function and to record your own choice. They are not optional and cannot be switched off.

General information only

Everything on OwnerSpec is published for general information. It is not professional advice and it cannot account for your specific property, equipment, supply or local rules. Use it to understand a problem and to ask a professional better questions, not to replace one.

Health

Some of what we cover touches drinking water and indoor air. Nothing on this site is medical advice. We do not diagnose any condition, and we do not claim that any product prevents, treats or cures anything. If you believe your water, air or home is making you unwell, contact your doctor and your local public-health or water authority.

Editorial policy

Fri, 11 Sep 2026 00:00:00 +0000

This site sells nothing and installs nothing. Its only asset is that its numbers can be checked. This page is how we intend to keep it that way.

Where numbers come from

In order of preference:

Regulations and standards. Published limits and test methods, cited by their number (for example an EPA maximum contaminant level, or an NSF/ANSI standard), never paraphrased into “experts recommend”.
Manufacturer documentation. Specification sheets, installation manuals and performance data sheets, linked to the document rather than to a shop page.
Independent testing and academic literature, where it exists.

Retailer listings and marketing pages are used for price and availability only, never as the source of a technical figure.

2. What this site is

OwnerSpec publishes general reference information about household equipment: specifications, sizing calculations, compatibility data and product comparisons. It is published for general information only. It is not professional plumbing, electrical, construction, medical, financial or legal advice, and it is not a substitute for a qualified professional or for laboratory testing of your own water, air or installation. See our disclaimer.

About OwnerSpec

Mon, 01 Jan 0001 00:00:00 +0000

OwnerSpec is an independent reference site for the equipment people own and maintain in their homes. It exists because the sizing and compatibility questions that decide a purchase are almost always answered by the company selling the hardware.

What we publish

Diagnostics. A symptom or a test result in, a treatment class out, with the regulatory limit cited by number.
Sizing. Calculators that take the inputs you already have and return one answer, with the formula shown.
Compatibility. Model number to replacement part, including cross-fit alternatives.
Comparisons. The handful of pages where judgement is genuinely required, written against a stated method.

How it is funded

Some links are affiliate links. We may earn a commission when you buy through one, at no extra cost to you. It never changes a recommendation or a number. The full arrangement is in our affiliate disclosure, and how we decide what to recommend is in our editorial policy.
