1. Our Commitment to Transparency
AirQualityIndex.org provides air quality information, educational resources, technical explanations, calculators, product comparisons and tools designed to help visitors understand air pollution and make informed decisions about indoor air quality.
We believe visitors should be able to access useful technical information without being required to register, share their contact details or purchase a product.
To help support the operation, maintenance and continued development of this website, we may earn commissions or other compensation when visitors use certain links to third-party retailers, manufacturers or service providers.
This page explains how those commercial relationships work and how they relate to the information we publish.
2. What Are Affiliate Links?
Some links on AirQualityIndex.org may be affiliate links.
When you click an affiliate link and subsequently make an eligible purchase, the retailer or affiliate network may pay us a commission or referral fee.
You generally do not pay any additional amount because you use one of our affiliate links. However, prices, discounts, shipping charges, taxes and available offers are determined by the retailer and may vary by country, product and time.
Not every external link on this website is an affiliate link. Some links are provided solely as references to manufacturers, standards organizations, research institutions, government agencies or other useful resources.
3. Amazon Associates Disclosure
AirQualityIndex.org participates in the Amazon Associates Program, an affiliate advertising program designed to provide a means for websites to earn advertising fees by linking to Amazon and affiliated sites.
As an Amazon Associate I earn from qualifying purchases.
We may provide links to Amazon stores serving different countries, including Amazon.com and Amazon.in, depending on product availability and the visitor’s selected shopping market.
International redirection or affiliate-link localization may be used where supported. The availability of an Amazon store, product or affiliate program does not guarantee that every purchase will generate a commission.
Amazon and its related trademarks belong to their respective owners.
4. Other Retailers and Manufacturer Programs
In addition to Amazon, AirQualityIndex.org may participate in affiliate or referral programs operated by other retailers, manufacturers, distributors and affiliate networks.
These relationships may relate to products such as:
- Air purifiers, filters and replacement components.
- Dehumidifiers and humidifiers.
- Ventilation equipment and related accessories.
- Indoor air quality monitors and sensors.
- Other equipment relevant to air quality and environmental management.
We may also provide non-affiliate links to manufacturers or retailers so that visitors can compare product specifications, availability and purchasing options.
Where we receive products, payments, sponsorships or other material benefits connected with specific content, we aim to disclose those relationships clearly in the relevant content.
5. Independence of Our Air Quality Advisor and Calculators
Our Air Quality Advisor and other technical calculators are intended to help visitors understand equipment requirements using disclosed inputs, calculation methods, assumptions and technical references.
Affiliate relationships should not influence the mathematical formulas, engineering assumptions, safety information or calculated equipment requirements presented by these tools.
For example, a calculated air purifier Clean Air Delivery Rate (CADR), estimated dehumidifier capacity or ventilation airflow requirement should be determined by the applicable calculation or published selection guidance, not by the availability of an affiliate commission.
Product listings and shopping links are separate from the underlying technical calculation.
Visitors are free to use our calculators and educational resources without clicking shopping links or making purchases.
6. Product Comparisons, Specifications and Reviews
AirQualityIndex.org may publish educational comparisons of product categories, technologies, technical specifications, certifications and available models.
We aim to distinguish between:
- Manufacturer-published specifications.
- Information published by independent testing or certification organizations.
- Calculated estimates and general technical guidance.
- Editorial comparisons based on available evidence.
- Products that have been independently tested by us, if any.
Unless expressly stated, a product appearing on this website should not be understood to have been physically purchased, tested or independently certified by AirQualityIndex.org.
Product availability, prices, specifications, model numbers, certifications and warranty terms may change. Visitors should verify important details with the manufacturer, certification body or retailer before purchasing.
An affiliate relationship does not constitute an endorsement, guarantee of product performance or confirmation that a product is suitable for every individual or situation.
7. How We Handle Product Selection and Commercial Relationships
We aim to present suitable product options based on relevant technical considerations, including equipment capacity, room characteristics, intended use, published specifications, compatibility and applicable safety information.
Where affiliate links are available, they may be offered as convenient ways to explore purchasing options.
We do not guarantee that every product, brand or retailer is included in our comparisons. The absence of a product does not necessarily indicate that it is inferior.
If a ranking, placement or article is sponsored or influenced by a paid promotional arrangement, that relationship should be identified clearly near the relevant content.
Affiliate links should not be represented as independent product verification.
8. Advertising and Sponsored Content
AirQualityIndex.org may display advertisements through third-party advertising networks, including Google advertising services.
Advertising revenue is separate from affiliate commissions. Advertisements may be selected or personalized by advertising providers according to their own policies and applicable consent requirements.
Paid advertisements and sponsored content, where present, should be distinguishable from independent editorial information.
We may receive compensation for sponsored content or promotional placements in the future. Any such material commercial relationship should be disclosed clearly and prominently.
9. Prices, Availability and International Shopping
AirQualityIndex.org serves an international audience. Products, retailers and commercial programs may differ across countries.
Prices shown by third-party retailers may vary because of currency exchange rates, local taxes, shipping fees, import duties, promotions and stock availability.
Any prices or product information shown on our website may be indicative, historical or subject to change unless explicitly identified as current and verified.
The final price, applicable terms, delivery arrangements, warranty conditions and return policy are determined by the seller.
Visitors should review the seller’s current information before placing an order.
10. Third-Party Websites and Privacy
When you click a link to a retailer, manufacturer, affiliate network or other external website, you leave AirQualityIndex.org.
Third-party websites may use cookies, tracking technologies or referral identifiers to attribute qualifying purchases, measure performance or provide their services.
Their privacy policies, cookie practices, terms of sale and customer-service arrangements are outside our control.
AirQualityIndex.org does not require visitors to provide their name, email address or telephone number simply to use its public air quality calculators.
For more information about data collection and website technologies, please review our Privacy Policy.
11. No Obligation to Purchase
Our educational content, public air quality information and available calculators can be accessed without making a purchase.
Using an affiliate link is entirely optional. Visitors may compare options, visit manufacturers directly, purchase from another retailer or decide not to buy anything.
We encourage visitors to consider their actual technical needs, budget, maintenance requirements and local product support before making purchasing decisions.
12. Limitations of Information
The information on AirQualityIndex.org is provided for general educational and informational purposes.
Technical calculations may rely on simplified assumptions, published guidance, user-supplied inputs or data from third-party sources.
They do not replace professional engineering assessment, medical advice, product installation instructions or applicable building, electrical and safety requirements.
Air quality observations, health information and product specifications may be subject to uncertainty, changes and limitations.
Please consult qualified professionals where a decision involves significant health, safety, building compliance or engineering risks.
13. Updates to This Disclosure
We may update this Affiliate Disclosure to reflect changes in our commercial relationships, advertising practices, website functionality or applicable requirements.
The latest version will be published on this page with its revision date.
