Where the site earns affiliate money, and which devices can carry a purchase link

We earn affiliate money in one place: purchase links on radon test kits and monitors. A purchase link appears only inside a device card, on device pages, the devices listing, the test kits and monitors guide and blog posts about devices. It never appears on a provider, place, dataset, report, tool or FAQ page, and never on a page about health, guidelines, interpretation, prevalence or evidence.

An affiliate relationship never affects which devices we list, their order or what we say about them. The price you pay is the same.

Purchase links are labelled, and we may earn a commission

A device card is in one of four states, and the label you see says which.

• Affiliate: “Purchase link. We may earn a commission.”
• Manufacturer: “Manufacturer link. No affiliate program. We earn nothing.”
• Recalled: no purchase element; the card links to the Health Canada notice as evidence.
• No longer listed: no purchase element; the card states the reason and the date.

On any page with a purchase link, you see the disclosure sentence directly under the first one, linking to this page. We mark affiliate links as sponsored in the page’s code as well as in words. We never dress them up as government links, scientific citations, Health Canada recommendations or independent research.

A commission does not mean Health Canada recommends the product, that the Canadian government or a researcher endorses it, or that we guarantee it. It does not mean the device suits every home, or that it got favourable coverage because it pays.

A recalled or not-recommended device gets no purchase link

A device must pass all three:

• Passed C-NRPP performance testing: on C-NRPP’s consumer list, or approved on its professional list.
• Not on C-NRPP’s not-recommended list.
• No open Health Canada recall.

Rules we hold ourselves to:

• We never link a device on the Government of Canada Recalls and Safety Alerts database, whatever it pays.
• Commission rates never decide whether a device is mentioned, how it is described, its order, or what health and testing pages conclude.
• Health risk, evidence, interpretation, prevalence and result pages carry no affiliate links.
• We disclose any free product on the page, not in a footer.

We compute the rules from the devices dataset, so a purchase link disappears on its own when a record stops qualifying.

A maker enters a device in C-NRPP’s consumer testing by supplying units. A device missing from that list was not entered, which says nothing about a failed test. Health Canada tests devices separately and issues recalls, and some devices sit on neither list while under test or review.

See every tested device with its status. Check the records the rules use.

Every eligible device is listed whether or not it pays a commission

We list every device that meets the rules, whether or not an affiliate program exists for it. Where no program exists, the card carries a plain purchase link that pays us nothing. Devices appear in a neutral order set by a stated field in the dataset, never by commission.

We have no affiliate arrangements with mitigation contractors or lead generation services. As of 18 October 2026 we have no affiliate relationship for any device, so every purchase link is a plain link. This sentence is the list of our commercial relationships, updated with its date whenever that changes.

Evidence about a device never comes from the seller

We source every claim about a device to the C-NRPP performance table or a Health Canada notice, never to a manufacturer or seller. The purchase link is a separate, labelled element, never a fact’s source. A manufacturer link carries no affiliate marking.

The words we use:

• “Approved”: only where Health Canada says so, or the device is on C-NRPP’s professional list.
• “Listed”: a consumer device on C-NRPP’s consumer list; “recommended”: C-NRPP’s word for one that reaches its minimum grade.
• A listed consumer device is not approved for professional use.
• Health Canada’s terms are electronic radon monitor (ERM) and professional grade ERM.

Disclosure also has legal reasons. Under Canada’s Competition Act, an undisclosed material connection between a publisher and a seller can be misleading. Ad Standards updated its influencer marketing guidelines in October 2025 to cover affiliate marketing. Since 20 June 2025, private parties can apply to the Competition Tribunal over deceptive marketing.
