Explain the air-quality claim without promising health outcomes.

An indoor air quality builder page should explain the documented feature, its project scope and the limits of its evidence. Separate equipment specifications, verified installation and test reports before writing a claim. Keep health statements held when the evidence does not support them, and identify the qualified reviewer for unresolved questions.

What does an indoor air quality claim need to explain?

Start with the buyer's question: what supports the air-quality wording on this home? A feature name alone leaves that question open. Write down the exact proposed statement before collecting attractive photographs or product descriptions. Identify whether it describes a material choice, equipment, installed work or a measured condition.

The EPA's indoor air quality guidance distinguishes source control, ventilation and air cleaning or filtration. Source control addresses pollutant sources or emissions. Ventilation concerns outdoor air entering the home. Filtration addresses pollutants collected by an air-cleaning system. These broad categories help organize questions; they do not prescribe a system for your project.

The same EPA guidance warns that its advice does not assure complete protection from every indoor pollution hazard. It also explains that air cleaners generally do not target gaseous pollutants. A filter description therefore cannot carry an unrestricted claim about everything in a home's air. Ask the responsible professional what the actual project evidence supports.

Keep these categories separate in the writing brief. A material document belongs with the specified material and its stated property. A ventilation document belongs with the described system. A filtration document belongs with the relevant equipment. Do not combine their labels into an invented whole-home certification.

Use the positioning library to connect a supported distinction with buyer understanding. This page's task is narrower: show how you reached one air-quality sentence. It does not establish an environmental condition or advise a buyer about a medical concern.

Which evidence supports the proposed public sentence?

Sort the available records before you write. The following categories are an editorial proposal, not a testing standard. Each category answers a different question. Keep the original source privately retrievable, including its revision and the project reference. An empty field means the writer still lacks evidence.

A product document may help identify an equipment category. It does not, by itself, show that the item reached this home. An installation record may identify completed work. It does not automatically describe the home's air under occupied conditions. A report needs its own context before a writer can summarize it.

If a test report exists, ask what was measured and where. Record the test date, operating conditions and exclusions stated in the source. Leave missing conditions unknown. Do not fill them from another home's report or a general description of the testing method.

Read the conclusion with the person responsible for explaining the report. Ask whether the proposed sentence implies more than the report establishes. Keep a project-specific result attached to that project. One reviewed result does not establish a standard result for every home you build.

The builder proof-point register provides a home for approved wording and publication locations. Keep air-quality evidence distinct from the documents behind builder energy performance claims. A source supporting an energy statement needs a separate review before supporting an air-quality statement.

How would a fictional air-quality claim review work?

Consider an unnamed, entirely fictional project. Its imaginary writing folder contains a draft ventilation equipment specification and a photograph of an equipment cabinet. The folder has no verified installation record or test report. Equipment ratings, operating settings and test conditions remain unknown. This example describes no actual home.

The proposed headline says, “Healthy indoor air for your family.” Hold that statement. The fictional folder cannot support the health outcome, and the image does not resolve the missing evidence. The writer should record the held sentence separately from wording that can describe the draft specification.

A useful private review entry reads: “Evidence category: specified equipment. Installed-scope source: unknown. Test context: unknown. Health statement: held. Qualified reviewer: not yet assigned.” This entry exposes the exact writing gap without implying that an unseen professional has approved anything.

Fictional public excerpt: “The draft specification identifies proposed ventilation equipment for this home. Installation and project air-quality testing have not been verified for this page. The specification describes a proposed feature; it does not establish a health outcome.” Publish such wording only when the corresponding real record and status have been checked.

For a real page, decide whether the pending feature helps the buyer at all. You can omit an unresolved feature rather than publish a paragraph about missing documents. Keep the question in the private brief so a later revision can use verified evidence when it becomes available.

The FTC's truth-in-advertising overview states that advertising must be truthful, avoid misleading consumers and have scientific evidence when appropriate. It does not approve this fictional wording or worksheet. Use qualified review for the actual claim and its evidence before publication.

Read the headline, description and caption alongside the excerpt. A cautious paragraph cannot repair a broader health assurance elsewhere on the page. Remove unsupported implications from every place the claim appears, including downloadable summaries and image descriptions.

How do you prepare an air-quality claim brief?

Copy this worksheet into a project content assignment. It is an original editorial proposal for organizing evidence. It is not an institutional requirement or an inspection form. Complete a separate brief for each proposed claim when the supporting sources or limitations differ.

Private source and revision:
Supporting source section:
Unresolved evidence:
Approved public sentence:
Approval status and date:

In the exact-claim field, paste the sentence as a buyer will see it. Avoid a shorthand topic such as “better air.” The reviewer needs to assess the actual assertion. If the sentence changes during editing, return the new wording for review rather than carrying forward approval of an older sentence.

For installed scope, name the project record and the work it confirms. Do not place private document links in public copy. For test context, distinguish “no report supplied” from “a report supplied without needed conditions.” Both remain evidence gaps, but they call for different follow-up questions.

1. Capture the claim. Include the proposed headline, body sentence and caption.
2. Classify the evidence. Separate specifications, verified installation, test results and unsupported assertions.
3. Check project identity. Match each source to the home and revision under discussion.
4. Preserve limits. Record unknown conditions and exclusions before simplifying the explanation.
5. Request qualified review. Ask the responsible professional to confirm the interpretation and permitted scope.
6. Approve the public wording. Record the final sentence and the trigger for another check.

Bring reviewed distinctions into the Positioning stage. A marketing writer can organize the records and explain approved facts. Technical interpretation stays with the qualified project reviewer. Keep an unresolved review visibly pending in the brief.

What should the project page show around the claim?

Place the feature description near its supporting context. Name whether the source describes proposed or completed work. If a public report excerpt is available, explain its scope beside the relevant sentence. Do not make a buyer search the footer for a limitation that changes the claim.

If you later use an informative image, write a text alternative for its meaning in context. The W3C informative-images tutorial, including Example 2, explains how images supplement nearby information. That guidance concerns image presentation. It does not verify equipment, installation or indoor conditions.

Keep captions equally narrow. A photograph of a component should not acquire a whole-home performance claim through its label. Confirm image rights separately from technical accuracy. No photograph or project document is supplied with this article, and no actual reuse permission is established here.

Use the custom-builder website page guide to place the explanation where buyers can find it. For foundation-related evidence, the companion sealed crawlspace project-page guide covers assembly scope. A crawlspace description needs its own evidence before it supports any air-quality statement.

When equipment or project scope changes, revisit the sentence before reusing it. Preserve the former approved wording in the private record. Give the next writer the current source, its limitation and the unresolved question together.
