Most Americans don't know they can pay for an air purifier with pre-tax dollars.
In a national survey commissioned by TrustedAir, 72% of adults didn't know air purifiers qualify for HSA and FSA funds, even though nearly half of them hold one of those accounts.
did not know air purifiers can be bought with HSA or FSA funds (with a letter of medical necessity).
have an HSA or FSA, yet most still didn't know an air purifier qualifies
would be more likely to buy a purifier if they knew it was eligible
have a household member with allergies, asthma, or dust & dander sensitivity
The confusion isn't limited to people without the accounts.
You might expect the people leaving money unclaimed to be those who don't have a health spending account in the first place. They aren't. Among the 48% of respondents who do hold an HSA or FSA, most had no idea an air purifier was an eligible expense.
of respondents who have an HSA or FSA still didn't know they could use it to buy an air purifier.
Knowing changes the decision.
Eligibility isn't a footnote to buyers, it moves the purchase. Three in four adults said they'd be more likely to buy an air purifier once they knew it qualified, and among people who actually hold the accounts, that jumped to nearly nine in ten.
more likely to buy if they knew it was HSA/FSA-eligible
more likely to buy — the people with funds ready to spend
40% said they'd be much more likely to buy — the single largest response.
The demand is already in the home.
This isn't latent interest in search of a reason. The conditions that commonly support eligibility (allergies, asthma, dust and dander sensitivity) are already present in most households surveyed.
75% said they're concerned about the air quality inside their own home.
It isn't cost. It's awareness.
When people who'd never used their accounts this way were asked why, the answer wasn't price or paperwork. The most common reason, by a wide margin, was simply not knowing it was an option.
in FSA funds are forfeited by Americans every year (Employee Benefit Research Institute) — and 18% of those surveyed said they'd personally lost FSA money by not spending it in time.
A benefit people already have, on a purchase they already want.
The takeaway is straightforward: eligibility is real and interest is high, but the awareness gap keeps pre-tax dollars sitting unused on a purchase most households have a reason to make.
TrustedAir built the TruFlow's checkout to close that gap. The TrustedAir TruFlow Air Purifier, a HEPA purifier with a real-time sensor that shows indoor particulate levels, offers an HSA/FSA payment option through Truemed, which coordinates the letter of medical necessity as part of the purchase. Eligible buyers can put pre-tax dollars toward it without navigating the paperwork on their own.

This survey was conducted online in July 2026 among 500 U.S. adults via a 3rd party online surveying service, with responses balanced to reflect the national adult population by age, gender, and region. Subgroup figures for HSA/FSA holders are based on the 240 respondents who reported having one of the accounts. As an online, opt-in sample, results are subject to a credibility interval rather than a traditional margin of error.
