How to choose without relying on marketing rankings

• Air purifiers must be assessed by filtration, CADR, room size and replacement-filter access.
• A humidifier adds water vapour and requires regular cleaning; it is not a HEPA purifier.
• A decorative salt lamp should not be marketed as an effective air-cleaning device.

FAQ

Does the top position mean the product has the best test score?

No. The order illustrates different buying needs and product formats; no standardized performance testing was conducted for this article.

How should I check the exact variant before ordering?

Confirm the model number, pack size or colour, manufacturer specifications, seller details, replacement parts or consumables where relevant, return terms and current Amazon India listing.

Should I pick a product just because a feature is mentioned?

No. Listed capabilities need to be matched to use, compatibility, personal comfort, upkeep and any safety restrictions. More features are not automatically better.
