AAAAI vs ACAAI for Exhibitors
Side-by-side data and our editorial take on which conference is the right exhibit investment for your medical device.
By Buzzbox Media · Last reviewed August 3, 2026
If you exhibit medical devices, AAAAI and ACAAI are likely both on your shortlist. Both serve overlapping clinical buyers, but the audience composition, booth economics, and exhibit floor experience differ in ways that materially affect ROI. AAAAI draws 6,000 attendees with an estimated all-in 10×10 of $6,500-$13,000, read from the published exhibitor prospectus. ACAAI draws 3,000 attendees with no booth pricing published by the organizer. Below is the side-by-side data plus our editorial take on which conference fits which kind of exhibitor.

Why exhibit at AAAAI
The larger of the two major US allergy/immunology meetings (AAAAI vs ACAAI), with 6,000+ attendees and 150+ exhibitors. Strong KOL presence for biologics companies, immunotherapy device manufacturers, and allergy diagnostic firms. Philadelphia 2026 location is accessible from major East Coast pharma/biotech hubs.
Why exhibit at ACAAI
The more practice-oriented of the two A/I meetings, attracting community and private-practice allergists who make independent purchasing decisions for their offices. If you sell allergy testing devices, immunotherapy delivery systems, or practice management software, ACAAI attendees are more likely to be direct buyers than the academic audience at AAAAI.
Why skip AAAAI
Allergy/immunology is a relatively small specialty. If your device serves broader pulmonary or ENT applications, consider ATS or AAO-HNS instead. Both AAAAI and ACAAI serve similar audiences, so exhibiting at both may be redundant unless your product requires both academic (AAAAI) and community practice (ACAAI) channels.
Why skip ACAAI
Smaller audience (~3,000 vs AAAAI's 6,000) and lower KOL density. If you need clinical trial partnerships or academic endorsements, AAAAI is the better venue. Exhibiting at both AAAAI and ACAAI in the same year may be redundant for companies with limited trade show budgets.
AAAAI booth figures are estimates read from its published exhibitor prospectus ↗, not quotes. ACAAI publishes no booth pricing we can link to, so no cost is listed for it. See the official ACAAI site ↗ for exhibitor details. Confirm current pricing with each organizer before committing a budget.
Frequently Asked Questions
Does AAAAI or ACAAI have more decision makers?
AAAAI does, on our estimate: roughly 3,000 effective buyers against about 1,650 at ACAAI. Effective buyers multiplies total attendance by the share of attendees who hold purchasing authority, so AAAAI works out to about 6,000 attendees at roughly 50% authority, and ACAAI to about 3,000 at roughly 55%. Both inputs are estimates drawn from organizer reporting and our own exhibitor research, so read the gap as directional rather than exact.
