For years, homeowners and HVAC professionals have relied solely on a single furnace filter to protect indoor air. But new independent lab testing confirms that there’s a better way to clean the air we breathe - right at the source.
In a recent study conducted by Aerosol Research and Engineering Laboratories (ARE Labs) in compliance with FDA Good Laboratory Practices (21 CFR Part 58), the Impeccable Air Return Vent Filter was tested for its ability to reduce volatile organic compounds (VOCs) and airborne particulates within a simulated HVAC duct system.
The results? Impeccable Air’s filters showed remarkable efficiency in capturing harmful particles and chemicals, helping homeowners achieve cleaner, healthier indoor air.

The goal of the study was simple: To measure how effectively the Impeccable Air filtered return grille system could reduce VOCs (chemicals commonly emitted by cleaning agents, paints, and plastics) and capture airborne particulates of various sizes, from ultrafine dust to coarse debris.
These filters were tested as an add-on system for existing HVAC return grilles, using the home’s natural airflow to continuously clean and refresh indoor air.
ARE Labs performed two primary tests:
VOC Reduction
Tested chemicals: Formaldehyde and Limonene, two common household VOCs linked to irritation and long-term health risks.
Measurement: Monitored over 60 minutes using an FTIR gas analyzer.
Particulate Capture Efficiency
Tested particles: Arizona Road Dust, covering multiple particle sizes (<0.5 µm to 20 µm).
Measurement: Conducted with an Aerodynamic Particle Sizer.
Control trials were run simultaneously to account for natural decay.
VOC Reduction
Formaldehyde: 22.13% reduction with the filter vs. 11.46% without.
Limonene: 38.97% reduction with the filter vs. 22.92% without.
These results demonstrate that Impeccable Air filters can actively reduce harmful VOC levels that linger in indoor environments.
Particulate Reduction
The filters achieved remarkable particle removal efficiencies across all size ranges:
|
Particle Type |
Size Range |

|---|---|---|---|
|
Ultrafine |
<0.5 µm |
89.94% |

95.77% |
30.22 |
|
Coarse |
5–20 µm |
99.99% |

These findings confirm that Impeccable Air filtered return vents:
Capture and neutralize airborne contaminants before they circulate through the home.
Reduce furnace filter clogging and system strain.
Support cleaner, more efficient HVAC performance.
Help remove harmful chemicals and particles that impact respiratory health.
The results from ARE Labs confirm what Impeccable Air customers already experience every day - cleaner air, fresher spaces, and more peace of mind.
By adding filtration at each return vent, we’re not replacing traditional HVAC filters — we’re enhancing the system to capture contaminants earlier and more efficiently, where airflow is slowest and filtration is most effective.
The Impeccable Air Return Grille Filter demonstrated measurable, lab-verified improvements in indoor air quality - reducing both chemical pollutants (VOCs) and particulates of all sizes by up to 99.99%.
This groundbreaking test validates Impeccable Air’s mission: To protect homes from the inside out by transforming every return vent into a high-efficiency air purification point.
