Mission Pure Air was founded by Jason and Elizabeth Plein, a husband-and-wife team with over 40 years of combined experience in the restoration, environmental, and indoor air quality industries. As the owners of both Mission Pure Air and Restoration 1 of Avondale, they bring a unique combination of hands-on field expertise, advanced certifications, and medical-grade testing knowledge to every home and business they assess.
Their background in restoration provides them with a profound understanding of how water damage, building materials, HVAC systems, and hidden moisture can lead to mold growth, biological contamination, and mycotoxin exposure. Through their commitment to thorough environmental assessments and advanced training, they ensure that every assessment is conducted with precision and accuracy, prioritizing the health of their clients.

Most indoor air quality companies lack real‑world experience. Jason and Elizabeth have spent decades working directly inside water‑damaged buildings, fire‑impacted structures, contaminated environments, and medically sensitive homes across Arizona. Their background is not theoretical or classroom‑based, it comes from thousands of hours spent identifying real sources of mold, moisture, and environmental triggers that affect families every day.
As IICRC Master Restorers with advanced certifications in water, fire, odor, trauma, and the IICRC MRS - Mold Remediation Specialist, they understand how buildings fail, how contaminants move, and how indoor environments impact health. Their work has included complex loss environments, medically fragile clients, CIRS and MCAS‑affected households, and properties where traditional testing failed to identify the true source of exposure.
This depth of experience allows them to interpret airborne data accurately, recognize patterns that others miss, and guide clients toward the right next steps without unnecessary testing or conflict of interest. Their hands‑on background is the foundation of Mission Pure Air’s medically aligned, real‑world approach to environmental assessment.
When your health or your family’s well‑being is on the line, you need testing that delivers clarity not guesswork. Mission Pure Air uses advanced airborne diagnostics and specialized mycotoxin evaluation methods to provide a deeper understanding of your indoor environment. Our approach goes far beyond traditional air sampling by analyzing the full volume of air in each room and identifying airborne patterns that standard tests routinely miss.
Every assessment is performed with medically sensitive clients in mind, including individuals dealing with CIRS, MCAS, chronic inflammation, respiratory irritation, or unexplained symptoms that change from room to room. Our testing is unbiased, conflict‑free, and designed to support accurate decision‑making without unnecessary sampling.
With real‑time airborne data, targeted mycotoxin evaluation, and decades of hands‑on experience in complex environments, you receive a level of insight that helps you understand what is happening in your home and what steps may be needed next.
Jason and Elizabeth built Mission Pure Air with a simple promise: to bring honesty, clarity, and real expertise to an industry that had become confusing and overpriced. For years, they watched families struggle to get reliable answers while other companies charged exorbitant fees for testing that offered little real value. Mission Pure Air was created to fill that gap by providing medically aligned, real‑time environmental assessments that people can trust.
As the owners of Mission Pure Air and its sister company, Restoration 1 of Avondale, Jason and Elizabeth remain hands‑on in every aspect of their work. They are physically present on every job, bringing decades of real‑world experience inside water‑damaged buildings, contaminated environments, and medically sensitive homes. Their approach is personal, transparent, and grounded in the belief that families deserve accurate information—not fear‑based sales tactics or inflated testing packages.
Mission Pure Air operates as a dedicated assessment service, focused solely on delivering clear airborne data and environmental insight. And because transparency matters, we always recommend that third‑party Indoor Environmental Professionals perform any laboratory‑based testing for confirmation and always handle post‑clearance verification. This ensures that your results are unbiased, independently validated, and aligned with best practices for medically sensitive environments.
This commitment to integrity is the foundation of everything Jason and Elizabeth do, and it’s why families across Arizona trust them with their homes and their health.
