● Class Action Complaint · Filed Feb. 19, 2026
Alen Corporation Sold Fake HEPA Air Purifiers to Pandemic-Scared Consumers for Years
While Americans fled wildfires and COVID-19, Alen pocketed the HEPA price premium on filters that independent testing proved never met the standard.
● CRITICAL SEVERITY
TL;DR
Alen Corporation, one of the country’s leading air purifier brands, spent years advertising its BreatheSmart 45i and FLEX models as carrying true HEPA filters capable of removing 99.97% of airborne particles, including COVID-19 and wildfire smoke. Independent laboratory testing commissioned by plaintiffs’ counsel proved those filters never met the HEPA standard. Alen never performed the individual filter testing required under industry rules to make a HEPA claim in the first place. Families who spent up to $482 on an air purifier because they feared for their health received a product worth measurably less than what they paid for.
Alen charged a premium for protection it could not deliver. That is not a technicality. It is fraud.

What They Did
Willful misrepresentation of filter certification
| 01 | Alen labeled the BreatheSmart 45i and FLEX as “HEPA” air purifiers on Amazon, its own website, and on retail packaging, despite never individually testing each production filter as required for a valid HEPA designation under IEST-RP-CC001, EN 1822, and ISO 29463 standards. | high |
| 02 | Independent laboratory testing commissioned by plaintiffs’ counsel, conducted under the IEST-RP-CC001 protocol and performed by an ANAB/ANSI-certified facility, confirmed the filters failed to remove 99.97% of particles at the critical 0.3-micron benchmark. The filters do not qualify as HEPA under any applicable standard. | high |
| 03 | Alen advertised the 45i as equipped with a “pure” and “medical grade” HEPA filter that “eliminates 99.9% of pollutants as small as .1 microns.” Those claims are expressly false. The filter failed even the less demanding 99.97% threshold at 0.3 microns. | high |
| 04 | Both the BreatheSmart 45i and FLEX share the same filter, meaning both product lines are implicated. The same deceptive HEPA label applied to every consumer who purchased either model or its replacement filters between 2022 and 2025. | high |
| 05 | Plaintiffs allege Alen knew, through its own internal testing or deliberate absence of testing, that its products were not HEPA-grade. The company continued marketing and selling the units for years after this knowledge was or should have been established. | high |
| 06 | Alen received written notice from plaintiffs’ counsel on January 14, 2026, documenting the false HEPA claims and demanding restitution. Alen failed to cure the breach or provide any adequate relief, prompting the filing of this class action on February 19, 2026. | high |
Cashing In on Fear
Revenue extracted through a public health crisis
| 01 | Alen deliberately capitalized on pandemic-era fear of airborne COVID-19 transmission and annual wildfire smoke events to drive sales of products it knew or should have known did not meet the standard consumers were paying for. | high |
| 02 | The HEPA price premium represents the full margin between what a non-HEPA purifier would command in the market versus what Alen charged. Plaintiffs seek recovery of that premium for every consumer who was overcharged. | high |
| 03 | The global air purifier market reached $18.01 billion, with the COVID-19 pandemic and wildfire crises identified as primary growth drivers. A significant portion of Alen’s market share is alleged to derive directly from the false HEPA claims. | med |
| 04 | Alen’s fraudulent HEPA designation gave it an unlawful competitive advantage over manufacturers who either genuinely tested their filters or truthfully marketed non-HEPA products at lower prices. This distorted the entire air purifier market to consumers’ detriment. | med |
The Health Cost of a Fake Filter
Real harm behind a fraudulent certification
| 01 | Consumers who purchased Alen purifiers believing they were protected from COVID-19 transmission, wildfire particulates, mold, and allergens were running machines that did not meet the filtration threshold necessary to provide that protection. Their homes were not as safe as advertised. | high |
| 02 | Poor air quality causes an estimated 100,000 premature deaths in the United States annually. Exposure to fine particulates is linked to depression, cognitive decline, and heightened anxiety. Consumers who believed they had HEPA protection were denied their best available defense against these harms. | high |
| 03 | Many purchasers bought Alen purifiers specifically because family members suffered from asthma, emphysema, or other respiratory conditions exacerbated by wildfire smoke. Those consumers placed their trust in HEPA certification precisely because their health depended on it. | high |
| 04 | The CDC identifies HEPA filters as the most efficient available for trapping exhaled particles from breathing, talking, and coughing. Alen’s false HEPA label caused consumers to believe their product met the CDC’s highest recommended standard for residential air safety. It did not. | high |
Regulatory Context and Enforcement Gap
Industry rules exist. Alen ignored them.
| 01 | Under IEST-RP-CC001 and related HEPA qualification protocols, each individual filter placed into commerce must be independently tested and verified before it can be sold as HEPA. Alen did not conduct this required per-unit testing. Design or prototype testing does not satisfy the standard. | high |
| 02 | The Federal Trade Commission has previously entered Consent Decrees against air purifier manufacturers including Honeywell for making false HEPA efficacy claims. Alen’s conduct mirrors exactly the type of deceptive trade practice the FTC has already condemned and acted against. | med |
| 03 | Ordinary consumers have no ability to test HEPA compliance before purchasing. Alen exploited that information asymmetry. The complaint is explicit: the false HEPA claims “were expressly false, not impliedly false.” There is no grey area here. | high |
| 04 | Despite receiving formal written legal notice in January 2026 demanding Alen cease its false claims and provide restitution, Alen took no corrective action. As of the filing date, Alen’s Amazon and website listings continued to advertise the products as HEPA. | high |
Financial Harm to Consumers
Real money extracted under false pretenses
| 01 | Named plaintiff Clint Petty paid $318.99 for the BreatheSmart 45i in November 2022, and an additional $81.09 for a replacement filter in May 2024. He would not have paid those prices, or would have paid substantially less, had Alen not advertised the product as HEPA. | med |
| 02 | Class members number at minimum in the hundreds, with aggregate claims alleged to exceed $5 million. The precise number of affected consumers will be determined through discovery of Alen’s sales records. | med |
| 03 | Plaintiffs seek full restitution of the HEPA price premium across all units sold from at least 2022 through 2025 on Alen’s own website, Amazon, and at retail stores. Prejudgment interest and attorneys’ fees are also sought. | med |
2020
COVID-19 pandemic begins. Wildfire seasons intensify across both U.S. coasts. Consumer demand for air purifiers surges dramatically. Air purifier market begins explosive growth toward $18 billion.
Nov. 2022
Named plaintiff Clint Petty purchases an Alen BreatheSmart 45i for $318.99 from Alen’s website, relying on the HEPA designation displayed on the product page.
2022–2025
Alen continuously advertises both the BreatheSmart 45i and FLEX on Amazon, its own website, and retail packaging as equipped with HEPA and “medical grade” filters. No individual per-unit HEPA testing is conducted or disclosed.
May 2024
Plaintiff purchases an Alen replacement filter for $81.09. The replacement filter uses the same filter design as the original unit, continuing the HEPA misrepresentation.
Late 2025
Plaintiffs’ counsel commissions independent ANAB/ANSI-certified laboratory testing of the Alen filter under IEST-RP-CC001 protocol. Results confirm the filter fails to achieve 99.97% particle removal at 0.3 microns. The filter does not qualify as HEPA.
Jan. 14, 2026
Counsel for plaintiff sends certified written notice to Alen Corporation at its Austin, Texas headquarters, documenting the HEPA misrepresentation and demanding the company cease false advertising and provide full restitution. Alen does not comply.
Feb. 19, 2026
Class action complaint filed in U.S. District Court, Southern District of California (Case No. 3:26-cv-01056-BAS-MMP) on behalf of a nationwide class of consumers and a California subclass. Jury trial demanded.
QUOTE 1
On Alen’s knowledge of the fraud
Core Allegations
“Defendant knew this, but continued hocking its wares, making a killing selling the Air Purifiers and replacement filters since the outset of the COVID-19 pandemic.”
💡 The complaint alleges this was not a mistake or an oversight. Alen knew what it was doing, and it did it anyway, at the exact moment consumers were most desperate for real protection.
QUOTE 2
On the testing failure
Core Allegations
“The filter did not remove 99.9% of particles at 0.1 microns. In fact, they do not even qualify as HEPA-grade because it failed to remove 99.97% of particles at 0.3 microns.”
💡 The filter failed at both the stricter 0.1-micron benchmark Alen advertised and the less demanding 0.3-micron minimum required for HEPA classification. It failed on every measure.
QUOTE 3
On deliberate exploitation of fear
Profit Over People
“Defendant has profited greatly from the explosion in the air purifier market brought about by the COVID-19 pandemic and yearly ‘once-in-a-lifetime’ wildfires that have ravaged the United States.”
💡 Alen’s business model during this period was built on a health crisis and an environmental catastrophe. It chose to monetize fear rather than earn its market share honestly.
QUOTE 4
On the per-unit testing requirement
Corporate Accountability Failures
“HEPA designation is not satisfied by historical design testing, prototype testing, or batch sampling alone. Each filter offered for sale as ‘HEPA’ must itself be tested and verified to meet HEPA requirements.”
💡 The rules could not be clearer. Alen bypassed a foundational, non-negotiable requirement and sold millions of dollars of product behind a certification it had not earned.
QUOTE 5
On consumer vulnerability to this fraud
Corporate Accountability Failures
“Consumers do not and cannot typically test the accuracy of a HEPA claim before purchasing an air purifier, and Defendant’s HEPA claims were expressly false, not impliedly false.”
💡 Alen knew consumers had no way to verify its claims. The deception was not ambiguous or technical. It was deliberate and direct.
QUOTE 6
On the FTC precedent
Corporate Accountability Failures
“The FTC has determined that false representations regarding the efficacy of HEPA air purifiers and filters constitute an unfair and deceptive trade practice.”
💡 This is not new legal territory. The FTC already put the industry on notice with its Honeywell consent decree. Alen had every reason to know what it was doing was illegal.
QUOTE 7
On the value consumers were denied
Economic Fallout
“The Products did not confer the value they promised to confer because they did not actually contain HEPA filters.”
💡 Every person who ran an Alen BreatheSmart in their home, in their child’s bedroom, or in their family’s living room, did so with a false sense of protection. That deception has a real cost.
❓
What exactly is a HEPA filter, and why does the distinction matter so much?
HEPA stands for High Efficiency Particulate Air. To carry that designation lawfully, a filter must capture at least 99.97% of airborne particles at 0.3 microns in size. This threshold matters because particles in that size range are the hardest to trap and include virus-carrying respiratory droplets, wildfire smoke particles, allergens, and mold spores. The CDC identifies HEPA as the most effective residential filter available. When a company slaps “HEPA” on a product without earning it, every family who bought that product was left materially less protected than they believed they were. That is not a fine-print disclosure problem. It is a direct health and safety failure.
How serious is this lawsuit? Could it actually succeed?
This lawsuit is built on unusually strong factual foundations. Plaintiffs’ counsel did not rely on allegations alone. They commissioned independent laboratory testing from an ANAB/ANSI-certified facility, which is the same type of lab companies use to validate their own filters. That lab tested the Alen filter under the precise protocol used in the United States for HEPA classification, and the filter failed at both the 0.1-micron and 0.3-micron benchmarks. Alen also left a documented paper trail: its Amazon listings, website, and product packaging all carry the specific false “HEPA” and “medical grade” claims identified in the complaint. The FTC has already sanctioned other companies for the same conduct via formal Consent Decrees. The legal framework (California’s UCL, FAL, and CLRA, plus fraud and warranty claims) is well-established. Assuming the lab results hold up under challenge, this is a lawsuit with teeth.
Did Alen know its filters were not HEPA?
The complaint alleges yes. Under HEPA certification rules, every filter sold must be individually tested before it can be called HEPA. Alen did not do this testing. Plaintiffs further allege that Alen’s own internal testing, or its deliberate avoidance of testing, revealed the filters were substandard. The complaint describes the misrepresentations as “expressly false,” and alleges that Alen “knew or should have known” the HEPA claims were false. Whether Alen acted with actual knowledge or willful blindness, both are forms of intentional wrongdoing. Neither is defensible.
Who was harmed by this, and how broadly?
The class includes every person who purchased an Alen BreatheSmart 45i, FLEX, or compatible replacement filter from at least 2022 through 2025. That means anyone who bought these products on Amazon, at retail stores, or through Alen’s own website. The complaint notes that Alen’s Amazon listings appeared on the “Amazon’s Choice” label, meaning the product was prominently promoted to consumers already searching for protection from health hazards. The harm falls hardest on people who bought specifically because they or a family member had a respiratory condition, immune vulnerability, or proximity to wildfire smoke. They paid a premium for medical-grade filtration. They received something substantially less.
Is there a broader pattern here, or is Alen an isolated case?
This case fits squarely into a documented pattern of consumer product companies exploiting unverifiable health and safety certifications to extract price premiums. The FTC’s prior action against Honeywell for false HEPA claims, referenced in the complaint, demonstrates this is not a novel scheme. When companies know that consumers cannot independently test claims, and when the certification carries a price premium, the incentive to lie is enormous. The HEPA fraud pattern is essentially identical to greenwashing in the sustainability space, false “natural” claims in food labeling, or “clinically proven” claims on cosmetics. The underlying logic is always the same: use a trusted certification term that consumers cannot verify, charge more for it, and pocket the difference. Until enforcement is consistent and penalties are genuinely deterrent, it will keep happening.
Why did it take a private lawsuit to catch this? Where were regulators?
This is the right question, and it exposes a structural failure in how product safety is enforced in the United States. The FTC has authority to regulate false health claims on consumer products, but it is under-resourced relative to the scale of the market it oversees. The air purifier market alone is an $18-billion industry. Without mandatory pre-market certification by an independent government body, companies can make HEPA claims with effectively no external check until someone sues them. Plaintiffs’ lawyers in cases like this one are performing, at private expense, the investigative and enforcement function that government agencies are funded to do but routinely fail to perform at scale. That is not a sustainable model for protecting consumers.
What can I do to prevent this from happening again?
Several things are within reach right now. First, if you purchased a BreatheSmart 45i or FLEX, document your purchase and monitor classaction.org and the Bursor and Fisher firm’s website for updates on how to join the class. Second, report Alen’s false advertising directly to the FTC at ReportFraud.ftc.gov. Complaints build the regulatory record and can trigger enforcement. Third, contact your elected representatives and demand stronger pre-market testing requirements for health and safety claims on consumer products. Fourth, share this story. Alen is a well-regarded brand with high Amazon reviews. The people most at risk of buying these products now are the people who have not seen this complaint. Visibility is accountability.
If Alen’s filters are not HEPA, what should I use instead?
Look for brands that publish verifiable third-party test certificates, not marketing language. True HEPA manufacturers can produce documentation showing individual filter batch testing under IEST-RP-CC001 or EN 1822. Brands such as IQAir, Blueair, and Coway have published independent test data. The EPA and CDC both maintain guidance on selecting residential air purifiers. If a company’s website links to actual lab test reports rather than just repeating “HEPA,” that is a meaningful indicator. Price alone is not a reliable guide: as this case demonstrates, high price plus HEPA label does not equal genuine protection.
