When wildfire smoke enters a home in Pasadena, Huntington Park, Altadena, Pacific Palisades Santa Monica, Bel Air, Brentwood, Glendale, Los Feliz, Sierra Madre, or Monrovia, the danger doesn’t end when the flames are extinguished.

Independent laboratory testing following the Eaton Fire and Pacific Palisades Fire revealed something far more concerning than odor or surface soot: a complex wildfire toxin burden embedded into homes exposed to Wildland-Urban Interface (WUI) fires. These fires burn not just vegetation—but vehicles, electronics, plastics, treated wood, insulation, batteries, and household chemicals, producing contaminants that persist long after evacuation orders lift.

At PuroClean of Pasadena and PuroClean of Huntington Park, our remediation protocols are the only ones in the country that are physician-directed, data-driven, and aligned with the most conservative public-health standards—not insurance shortcuts.

Below is a contaminant-by-contaminant breakdown of what post-fire testing actually shows, why it matters medically, and why choosing the right remediation partner determines whether a home is truly safe to reoccupy.

Combustion By-Products: Soot, Char, and Ash (Not Just a Cosmetic Issue)

In our experience, the testing found
Laboratory tape-lift samples confirmed widespread soot and char throughout the structure, including areas without visible residue. This is a critical red flag in WUI fires.

Why it matters
Soot from synthetic material combustion is acidic, carcinogenic, and capable of deep penetration into porous materials. Unlike wildfire ash alone, soot inside a structure strongly indicates burning plastics, foams, wiring, and furnishings.

Health risks include:

Why PuroClean is different
We do not rely on cosmetic cleaning or odor masking. Our teams use:

This approach aligns with ANSI/IICRC S700 Fire & Smoke Restoration Standard

Heavy Metal Contamination After the Wildfires: Lead, Chromium, Zinc, Copper, Nickel, and More

What the testing found
Dust wipe samples detected elevated heavy metals, including lead exceeding current EPA zero-threshold guidance.

Why it matters
Heavy metals originate from:

Health implications:

Why PuroClean is different
Lead and heavy-metal remediation is not general cleaning. We perform and coordinate:

Our physician oversight ensures decisions are made using health-protective thresholds, not outdated regulatory minimums. At Puroclean of Pasadena and Huntington Park we do NOT take shortcuts with wildfire smoke contamination.

Cyanide Residues: Invisible, Unforgiving, and Often Missed

What our testing experiences have found
Many homes have been found to have cyanide contamination in the ash. Even if cyanide is below laboratory detection limits, non-detect does not equal absence in WUI fires.

Why it matters
Hydrogen cyanide is released when:

Cyanide:

Why PuroClean of Pasadena and Huntington Park is different
We treat cyanide risk precautionarily, which means:

Volatile Organic Compounds (VOCs): Severe Indoor Air Contamination


Many of the homes we have remediated thus far have had total VOC levels measured >3,000 ng/L (severe), including:

Why it matters
These compounds:

Why PuroClean is different
We do not stop at air scrubbing. Our process addresses:

wildfire smoke
Air Sample VOC Testing

Formaldehyde & Aldehydes: Known Human Carcinogens in Wildfire Ash

What the testing found
Formaldehyde concentrations were elevated post-fire in the vast majority of homes we have remediated so far.

Why it matters
Formaldehyde:

Why PuroClean is different
We follow physician-directed clearance targets that aim for background residential levels, not just OSHA workplace limits.

Lithium Contamination: The Battery Fire Problem No One Is Talking About

What the testing found in many homes we have remediated after the Eaton and Palisades Fire:
Lithium residues were detected above the laboratory’s limit of quantitation. View the Lithium Safety Data Sheet Here.

Why it matters
Lithium comes from:

Health concerns include:

Lithium contamination is not removable from soft goods.

Why PuroClean is different
We understand lithium as a post-fire emerging contaminant, and our remediation plans include:

Why Physician Leadership Changes Everything

Most restoration companies are operationally driven and care more about speed, profitability, and turnover of jobs.
PuroClean of Pasadena and PuroClean of Huntington Park are medically driven and we strive to ensure that each home is returned to a level of safety that we would want for our own families.

Our physician leadership ensures:

This is why:

The Bottom Line: Not All Fire Cleanup Is Remediation

If your home was exposed to a WUI fire, surface cleaning is always insufficient and will put your family at risk or if you’re a landlord, open you up to liability. The data proves it.

True remediation requires:

That is what PuroClean of Pasadena and PuroClean of Huntington Park deliver—every time. We have an enormous amount of experience dealing with homes and commercial buildings affected by the Eaton Fire and Palisades Fire..

If you need a real answer, not reassurance, this is where the conversation starts.
