Test Results & Certifications
Each result below names the laboratory that ran the test, the standard it was run to, the size of the chamber, how long it ran, and which model was tested. Where a certificate applies, the certificate number is there so you can verify it in the issuing body’s own database rather than taking our word for it.
We don’t publish figures we can’t stand behind. That makes this page shorter than some you’ll see.
Certification
The PurAire SG- BPI-2, also sold as the SG-FCU-2, holds a UL Environmental Claim Validation for zero ozone emissions.
Certificate 344035-4710, issued by UL Verification Services Inc.
Product: Bipolar Ionizer PS-502T (PurAire BPI-2 / FCU-2)
Claim validated: measured ozone emissions during the use phase do not exceed 0.005 ppm, as tested by UL 867
Method: ECVP 2998, Zero Ozone Emissions from Air Cleaners, Third Edition 2020
You can check this certificate is current at SPOT.ul.com.
What this covers: The validation applies to the BPI-2 / FCU-2 (model PS-502T). It does not cover the BPI-1, the PurAire DUO or the AirPro-MAX. Those models are not covered by this certificate and we don’t claim they are.
Independent Test Results
These tests were run on the PurAire SG-BPI-1, (model PS-501T). The SG-BPI-1 is the single-tube version of the same unit as the SG-BPI-2. Both were tested by accredited laboratories in China on samples submitted by the manufacturer that builds our units.
Airborne Bacteria
Six organisms, tested separately, three runs each.
- Klebsiella pneumoniae — 99.99%, 99.97%, 99.98%
- Pseudomonas aeruginosa — 99.98%, 99.99%, 99.99%
- Salmonella typhimurium — 99.98%, 99.97%, 99.98%
- Acinetobacter baumannii — 99.98%, 99.98%, 99.98%
- Mycobacterium chelonei subsp. abscesses — 99.97%, 99.98%, 99.97%
- Bacillus subtilis spores — 99.08%, 99.05%, 99.09%
20 m³ chamber. 120 minutes. Technical Standard for Disinfection (2002), section 2.1.3.
CAS Testing Technical Services (Guangzhou) Co., Ltd — reports JKK24030021A(E), C(E), D(E), F(E), G(E) and H(E). CMA 201819000873, CNAS L7673.
About That Last Figure....
The standard sets 99.90% as its threshold. Bacillus subtilis spores came in below it, at 99.05 to 99.09%.
Spores are built to survive. They are harder to reduce than ordinary bacteria, which is exactly why they get tested — they show you where the limit is. Five of the six organisms cleared the threshold comfortably. The sixth did not, and we publish it because leaving it out would misrepresent what the panel actually found.
Gaseous Pollutants
Hydrogen sulfide 90.6%. Benzene 94.0%. TVOC 95.5%.
30 m³ chamber. 4 hours. JG/T 294-2010.
Guangdong Detection Center of Microbiology — report 2024FM00355R01E, verification code 6BDNV4J6. CMA 201819000883, CNAS L1747.
One note on this test: JG/T 294-2010 works out the test duration from the unit’s rated airflow, which for this model comes to five hours. The test ran for four. The laboratory recorded the difference and confirmed the result holds for the conditions tested.
What These Results Don't Tell You
Every figure above was measured on one model, in a sealed chamber, under laboratory conditions. A real room is not a chamber. Ceiling height, air movement, how often the door opens and what’s producing the odour or contamination in the first place all change what you’ll see in practice.
Test results describe the sample tested. They are not a performance guarantee for your building.
We Don't Audit Our Own Work
When a building or a site needs measuring, we engage TÜV SÜD Singapore. They are SAC-SINGLAS accredited for formaldehyde, TVOC, PM2.5 and respirable suspended particles.
They conduct the audit. They write the report. It carries their name, not ours.
Where a client would rather engage and pay them directly, that works too.
The measurement and the fix are done by different people. An accredited laboratory measures. We correct what the measurement found. The laboratory verifies.
About The Reports
PurAire units are built to our specification by our manufacturing partner in Shenzhen. They commissioned the tests above and have authorised us to cite them. The reports carry the manufacturer’s own brand and model numbers, which is why PS-501T and PS-502T appear on this page alongside the PurAire names.
Measured at Room Scale Under Stated Conditions
Every figure below comes from an accredited third-party laboratory, tested in a sealed chamber over a stated duration.
Reduction across six pathogens. Bacillus subtilis spores reached 99.05-99.09% – below the others, and we publish it that way.
