In this episode of Thyroid Pharmacist Healing Conversations, Dr. Wentz interviews Mike Feldstein, founder of Jaspr, about the hidden health effects of indoor air and practical solutions you can use today.  Mike explains how modern building practices trap pollutants, why classrooms are a high-impact target for filtration, and the real difference between small retail purifiers and commercial air scrubbers. Tune in to learn about the best choices for indoor air filtering, and how this and other simple steps can relieve conditions like asthma and allergies, help you get a more restful sleep, and support recovery for anyone with autoimmune disease and chronic sensitivities. What you’ll learn in this episode: Why indoor air is often more polluted than outdoor air: Unlike outdoor environments where wind, sunlight, and rain naturally cleanse toxins, our homes trap mold, VOCs, and bacteria inside. As a result, indoor air can be 5 to 10 times dirtier than the air outside, driving brain fog, fatigue, allergies, and asthma. Targeted changes like daily ventilation, high-efficiency air scrubbers, and simple monitors can transform your environment into one that supports healing instead of undermining it. How “sick building syndrome” affects your health: The energy-efficient buildings that started to be built in the 1970s seal in mold, chemicals, and poor ventilation. This hidden trade-off explains why so many people feel unwell in their own homes and workplaces. Why size and scale matter in air purification: Small, store-bought purifiers often work like golf carts – fine for light use, but not built for real health demands. Air scrubbers operate more like SUVs, moving far more air through larger filters and reducing pollutants on a much bigger scale. Choosing the right “vehicle” for your space can mean the difference between slightly cleaner air and truly life-changing results. Everyday toxins may be hiding in your home: Furniture, flooring, cleaning products, fragrances, and even diaper pails can release chemicals that linger in the air. These daily exposures add up, and clearing them can relieve symptoms you may not have connected to your environment. Air scrubbers vs. basic purifiers: Store-bought purifiers may only improve air quality by 10 to 20%, while air scrubbers like Jaspr can reduce pollutants by up to 99%. That level of clean air can be life-changing for those with asthma, autoimmunity, or chronic sleep issues. Clean air as a missing pillar of functional medicine: Just as water filtration and clean diets are now common practice, air quality deserves the same attention. Without it, even the best supplements and protocols may fall short of lasting results. Be sure to subscribe to the Thyroid Pharmacist Healing Conversations podcast so you don’t miss an episode!
