Reading Product Spec Sheets Without Falling for Buzzword Marketing
Spec sheets often pack in technical terms without explaining them. See a glossary approach to reading one honestly before comparing products.
Key takeaways
- Spec sheets often mix genuine certifications with unexplained marketing adjectives.
- A certification can be checked externally; a descriptive term like advanced or premium usually cannot.
- Build a simple glossary of terms before comparing two products, not while reading either spec sheet.
- Ask a supplier to explain any term that is not self-evident, rather than assuming it is standard.
- A supplier who cannot explain their own spec sheet in plain language is worth treating cautiously.
Why spec sheets pack in terms without explaining them
A spec sheet is written to sound impressive at a glance, not necessarily to be understood at a glance. Terms like medical-grade, advanced filtration or multi-stage protection appear frequently because they sound authoritative, whether or not the sheet explains what specifically backs them up.
This is not always deliberate obfuscation. Some suppliers assume buyers already understand the terminology, or copy language from an earlier version of the sheet without revisiting whether it still needs explaining. Either way, the effect on a buyer comparing several products is the same: a page full of confident-sounding terms with no easy way to tell which ones represent something verifiable.
Reading past the confident tone to what is actually being claimed is the first step to comparing spec sheets fairly rather than being swayed by whichever one sounds most technical.
A glossary approach: what each term actually means
Before comparing two spec sheets, it helps to build a short glossary of the terms that actually appear on both, rather than reading each sheet cold. CADR, clean air delivery rate in cubic metres per hour, is a measurable output figure. ACH, air changes per hour, is a target based on room size. H13 HEPA is a specific filtration grade, distinct from a lower H10 to H12 grade often marketed loosely as HEPA-type.
Once these core terms are defined once, in plain language, every subsequent spec sheet becomes faster to read, because the same handful of terms recur across most products in the category. AIRE's own technology page and CADR explainer are useful starting references for building that glossary.
This upfront work pays off every time a new product is compared afterward, not just for the one purchase decision in front of you.
Certifications versus marketing adjectives
The clearest way to separate substance from language on a spec sheet is to ask whether a term can be externally verified. FDA Class 2 medical device listing, CE, RoHS and ISO 9001 or 14001 are all certifications issued by a body outside the manufacturer, and can generally be checked through that body's own records.
Descriptive adjectives, premium, advanced, industry-leading, next-generation, cannot be verified in the same way, because they are the manufacturer's own characterisation rather than an external assessment. Neither is automatically dishonest, but only one category gives you something to check independently.
When a spec sheet leans heavily on adjectives and lightly on named, checkable certifications, that balance itself is informative, worth noting as part of the overall comparison rather than dismissing outright.
Questions to ask when a term isn't explained clearly
If a spec sheet term is not self-evident, ask the supplier directly what it means and how it was determined. A specific, confident answer, referencing a named test, standard or certifying body, is a good sign. A vague answer that restates the same adjective in different words is worth noting.
Useful questions include what specific standard or certification backs the claim, where it can be verified externally, and whether the term applies to the whole unit or just one component. These questions apply equally to any brand's spec sheet, including AIRE's own, our claims verification policy sets out how we expect our own claims to be checked using the same approach.
A supplier confident in their product will usually welcome these questions rather than treat them as an inconvenience.
Where to check the full technology breakdown
Once the glossary work is done, comparing spec sheets becomes a matter of matching what each product actually contains against the terms now understood, rather than being swayed by which one sounds more technical. Certifications, named filtration grades and specific mechanisms carry more weight than adjectives at this stage.
AIRE's technology page sets out the full seven-layer breakdown in plain language, aluminium pre-filter, cold catalyst, activated carbon, antibacterial layer, H13 medical-grade HEPA, UV-C sterilisation and anion release, as a reference for the level of detail worth expecting from any spec sheet, not only ours.
Reading with this approach turns spec sheet comparison from a guessing game into a checklist exercise.

Frequently asked
Why do spec sheets often use unexplained technical terms?
Spec sheets are written to sound authoritative, and terms like medical-grade or advanced filtration are used because they carry weight, whether or not the sheet explains what specifically backs them up. This is not always deliberate; some suppliers assume readers already know the terminology or reuse older language without revisiting it.
How can certifications be distinguished from marketing adjectives?
A certification, such as FDA Class 2 listing, CE or ISO 9001, is issued by an external body and can generally be checked through that body's own records. A descriptive adjective, such as premium or advanced, is the manufacturer's own characterisation and cannot be verified the same way, which is the clearest way to tell the two apart.
What questions help when a spec sheet term isn't clear?
Ask what specific standard or certification backs the claim, where it can be verified externally, and whether it applies to the whole unit or just one component. A confident, specific answer referencing a named test or certifying body is a good sign; a vague answer restating the same adjective is worth noting.
Is it reasonable to ask a supplier to explain every term on their own spec sheet?
Yes. A supplier confident in their product should be able to explain any term on their own spec sheet in plain language without hesitation. Treating these questions as reasonable due diligence, rather than an inconvenience, is a fair standard to hold any supplier to, including AIRE.
