Best ERMI and Environmental Mold Test Kits
A true ERMI (Environmental Relative Moldiness Index) test uses the EPA's DNA-based method on a vacuumed dust sample, and every accredited lab that runs it sells direct from its own site, not Amazon. Two Amazon-purchasable kits, ImmunoLytics and Seeml Labs, use a different method (gravity settle plates or surface swabs) with real lab analysis included. Both approaches are legitimate; they are not the same test. This guide is honest about which is which.
The Catch: Real ERMI Kits Are Not Sold on Amazon
Search "ERMI test kit" on Amazon and you will get gravity settle-plate kits, surface swab kits, and general "mold test kit" listings. None of them are made by the AIHA-LAP-accredited environmental labs that actually run the EPA's Mold-Specific Quantitative PCR (MSQPCR) method against the 36-species ERMI panel. Mycometrics, EnviroBiomics, and Assured Bio Labs, the three labs most often cited for real ERMI testing, all sell exclusively through their own websites. We checked: zero Mycometrics-brand listings turn up in Amazon search results for "mycometrics ermi test kit."
That is not a defect in this guide, it is the honest state of the market. If you want a legally recognized ERMI score, you order direct from an accredited lab and wait for lab turnaround. If you want a fast, cheap first screen with real lab-analyzed results, two different kits are genuinely purchasable on Amazon right now. We cover both categories below and say plainly which is which.

ImmunoLytics DIY Mold Test Kit
Four gravity settle plates and one swab kit, listed at $39.00 on Amazon and in stock. You set out a plate, let spores settle for about an hour, incubate 3 to 4 days, then mail it to ImmunoLytics' mycology lab for genus ID and spore counts, plus a free consultation. This is not a dust ERMI panel, it screens what settles from room air rather than what is in your carpet dust. Read our full ImmunoLytics review for the honest cons.
Seeml Labs DIY Mold 3 Test Kit
Listed at $22.00 on Amazon, 4.2 stars from 485 ratings, in stock with Add to Cart and Buy Now active. Three surface swab samples ship to a AIHA-LAP, LLC accredited lab with no extra lab fee and a free expert consultation on your results. It is a surface test, not a dust ERMI panel, and the listing itself says it is not for air quality testing. Use it when you can point to a specific suspect surface.
Mycometrics ERMI Test
Runs the actual EPA MSQPCR dust panel against the 36-species ERMI reference set. Collection uses an AccuCloth (Swiffer-style) cloth rather than a vacuum cassette, the simplest sample-collection method of the three accredited labs here. Direct order only, no Amazon or retail listing exists; a search for "mycometrics ermi test kit" on Amazon returns zero Mycometrics-brand results.
EnviroBiomics ERMI Test
A commercial environmental lab running EPA MSQPCR-equivalent dust DNA analysis, with add-on panels for Actino, mycotoxins, and endotoxins alongside the core ERMI. Several kits bundle a HERTSMI-2 score with the ERMI for one sample. Direct order only through envirobiomics.com; no Amazon listing exists under the EnviroBiomics brand.
Assured Bio Labs ERMI Molecular Mold Kit
Vacuum-collected dust sample run against the EPA-developed 36-species panel. The kit ships with all sampling materials, a return envelope, and free return shipping to the lab included in the price, so there is nothing extra to buy once you order. Direct order only through assuredbio.com.

Which One Should You Actually Buy
Match the test to what you actually need to prove:
You smell something and want a cheap first answer. Get the ImmunoLytics or Seeml Labs kit off Amazon. Both ship fast, both include real lab analysis, and both cost under $40. Neither produces a court- or insurer-recognized ERMI score, but both tell you whether something is actually growing.
You need a defensible number for a real estate deal, insurance claim, or a CIRS workup with a physician. Order direct from Mycometrics, EnviroBiomics, or Assured Bio Labs. Budget more, expect a longer turnaround, and confirm the lab's current AIHA-LAP accreditation on their site before you buy, since accreditation status can change.
You are not sure which surface or room to test. Start with a visual walkthrough before spending on any lab test. Our free 160-point mold checklist walks visible surfaces room by room so you spend testing money on the room that actually needs it.
Whichever path you choose, remember the EPA's own position: ERMI has been peer reviewed for research purposes but has not been validated for non-research, individual diagnostic use. Treat any score, from any lab, as one input for a certified indoor environmental professional to interpret, not a stand-alone verdict.
Screen visible surfaces with Mold Scanner AI
The app offers 266 guided photo prompts across 19 rooms, with 38 in Quick and 129 in Standard. It is not a professional inspection and it does not replace a lab test. AI-assisted visual screening result with variable processing time.
Get Early AccessFrequently Asked Questions
Can I buy a real ERMI test kit on Amazon?
No. True ERMI testing uses the EPA's MSQPCR DNA method on a dust sample, and every AIHA-LAP-accredited lab that runs it (Mycometrics, EnviroBiomics, Assured Bio Labs) sells the kit direct from its own website only. None of them list on Amazon. What you find searching "ERMI" on Amazon are related but different products: gravity settle-plate or surface swab kits with lab analysis, which screen for mold differently than a dust ERMI panel.
What is the difference between ERMI and the Amazon mold test kits?
ERMI vacuums a dust sample from carpet or flooring and runs DNA-based PCR analysis against 36 mold species, producing a single index score. The kits actually sold on Amazon under ERMI-adjacent search terms, like ImmunoLytics and Seeml Labs, use gravity settle plates or surface swabs that culture live spores in a lab. Both give you real lab data. Neither one is the EPA MSQPCR dust panel that produces an ERMI score.
Which test should I actually buy?
For a quick, cheap first screen of a specific room, an Amazon gravity-plate or swab kit with lab analysis is the fastest path and costs under $40. If you need a legally recognized ERMI score for a real estate deal, an insurance claim, or a CIRS diagnosis workup, order direct from an AIHA-LAP-accredited lab like Mycometrics, EnviroBiomics, or Assured Bio Labs. Their kits cost more and take longer, but the ERMI number is the one clinicians and inspectors actually reference.
Is a higher ERMI score always bad?
An ERMI score compares your dust sample against a national reference database, but the EPA itself states ERMI has been validated for research, not for clinical diagnosis or as a stand-alone remediation trigger. Treat any ERMI result, high or low, as one data point to discuss with a certified indoor environmental professional, not a final verdict.
