You Can’t See It. But You’re Breathing It.

When the air in your home isn’t healthy,
it can affect everything... your lungs, your brain, and your long-term well-being.

Radon, hidden mold, and fine particles are easy to overlook… until they start affecting your health.

Radon

Radon is the leading cause of lung cancer for non-smokers.

You can’t see, smell, taste, or feel it. It seeps in from the soil beneath your home. Long-term exposure affects more than the lungs. Studies have found that patients with Alzheimer’s and Parkinson’s have up to 10 times more radon in their brain tissue than those without these conditions. It comes from the earth’s crust and is in every home, everywhere.

The only way to know how much radon is in your home… is to test.

Mold

Mold spores are often hidden behind walls, under flooring, or inside HVAC systems, especially in buildings with past leaks or poor ventilation. Even when it’s not visible, mold can seriously impact how you feel day to day. It’s been linked to chronic fatigue, respiratory issues, skin irritation, brain fog, and trouble sleeping. Mold thrives in moisture-rich environments. Indoor humidity as low as 60 percent can support growth, and at 70 percent or higher, it can spread quickly and go completely unnoticed.

Air testing is a non-invasive way to identify whether mold is present and to
understand what types and how much may be circulating in your air.

Particulate testing service by The SafeAir™ Company

Particulates

Fine and ultrafine particles like soot, fiberglass, tire dust, and metal fragments are often present in indoor air, even when a space looks crystal clean. They can come from wildfires, construction, poor filtration, or aging building materials inside walls and ventilation systems.

These microscopic pollutants are small enough to enter the lungs, pass into the bloodstream, and cross the blood-brain barrier to reach the brain. Exposure has been linked to asthma, disrupted sleep, cardiovascular problems, and long-term cognitive decline.

The only way to know what you're breathing is to test.

Certified Testing Informs You
Exactly What You’re Breathing

The SafeAir™ Company offers certified radon testing, mold testing, and particulate testing across Los Angeles, Orange County, Ventura, and Santa Barbara Counties, using professional-grade instruments and accredited labs.

EPA certified continuous radon monitor used for radon testing

Precision Radon Detection

We offer certified radon testing using both EPA-certified continuous radon monitors (CRM), activated charcoal kits, and Alpha-track tests (for long-term testing), depending on the property type and testing requirements.

A CRM provides hour-by-hour readings and is required for residential real estate transactions.

For commercial or multifamily buildings, charcoal kits meet HUD and EPA standards and allow for cost-effective testing across multiple units while complying with all commercial financing contingencies. Your report includes clear results and guidance based on national safety thresholds.

Professional mold and particulate testing equipment by The SafeAir™ Company

Comprehensive Mold Analysis

We use precision industrial-grade instruments for non-invasive air and surface sampling to detect mold that may be hidden behind walls, under flooring, or inside HVAC systems.

In addition to lab testing, our technicians use professional-grade infrared cameras and moisture meters to identify areas of elevated moisture, often the source of hidden mold growth and unexplainable allergy symptoms.
Your lab report identifies the types and levels of mold present, compares indoor and outdoor air samples, and includes detailed findings and next-step recommendations.

Because we don’t mitigate, our findings and guidance are completely unbiased.

Accredited laboratory analysis for radon mold and particulate testing

Advanced Particulate Identification

The SafeAir™ Company identifies over 40 types of fine and ultrafine particulates commonly found in indoor environments, including fiberglass, insulation fibers, construction debris, soot, tire rubber, rust, metal fragments, silica, pollen, dust mites, and diatoms. These particles are often released during wildfires, construction work, renovation projects, or from aging building materials.

Many are small enough to bypass the body’s natural filters and can enter deep into the lungs or bloodstream.
Your report includes a detailed breakdown of what’s present and guidance on how to reduce your exposure based on our comprehensive findings.

Radon is a radioactive gas found in every home. It’s tasteless, odorless, and invisible. The only way to know how much radon is present is by testing.

Where does radon come from?

Radon comes from uranium in the Earth’s crust, breaking down into radium and then radon gas that rises into homes.

How does radon enter my home or building?

Through foundation cracks, walls, pipes, and even well water sources.

Mold

What is mold testing, and why is it important?

Mold testing is the process of assessing indoor air quality and surfaces for the presence of mold spores. It's important to know if mold is present as it can create long-term health issues and affect real estate value. If you've been experiencing mysterious symptoms, it might be time to inspect your environment.

How can I tell if I have a mold problem in my home or business?

Common signs include a musty odor, visible mold growth, water damage history, or otherwise inexplicable health issues. If signs and health symptoms persist, mold may be present but hidden behind the walls, under floors, or in the air ducts.

What are the health risks associated with mold exposure?

There’s no one-size-fits-all when it comes to mold—it affects everyone differently. While it might trigger eczema in one person, it could cause gut imbalances in another. Other symptoms include respiratory problems, asthma exacerbation, joint pain, muscle cramps, lightheadedness, abdominal pain, anxiety, weight gain, hair loss, poor memory, difficulty concentrating, and sensitivity to light.

Particulates

What is particulate testing, and why is it important?

Particulate testing measures the levels of microscopic particles in the air, such as dust, pollen, smoke, and other airborne contaminants. It is important because these particles can impact indoor air quality, trigger allergies, and contribute to long-term respiratory issues if left unaddressed.

How can I tell if I have a particulate problem in my home or business?

Common signs include excessive dust buildup, frequent allergy symptoms, poor air circulation, or visible haze in sunlight. If occupants experience coughing, sneezing, or irritation indoors, it may indicate elevated particulate levels.

What are the health risks associated with particulate exposure?

Exposure to airborne particulates can cause respiratory irritation, worsen asthma, trigger allergies, and in some cases contribute to long-term lung or cardiovascular issues.
