The Neuro Experience – “The Hidden Toxins You’re Breathing Every Day (And Don’t Even Know It)”

Host: Louisa Nicola & Pursuit Network
Guest: Mike Feldstein (Founder of Jasper)
Date: November 4, 2025

Episode Overview

This episode dives deep into a frequently overlooked but fundamentally important aspect of health: the quality of the air we breathe indoors. Host Louisa Nicola interviews Mike Feldstein, founder of Jasper (an advanced air cleaning company), about the hidden toxins prevalent in our daily environment, their acute and chronic health effects, and practical strategies to improve indoor air quality. The conversation ranges from Feldstein’s disaster restoration background and consumer misconceptions to the science of particulate matter and the actionable steps listeners can take right away.

Key Discussion Points & Insights

1. Why Air Quality Matters — The Unseen Threat

• Indoor Air Is Worse Than Outdoor Air:
  • Mike: “Indoor air is five to ten times dirtier than outdoor air.” (00:17, 05:15)
• Invisible Danger:
  • Most people ignore air quality because it's invisible, but many toxins and allergens are present, coming from finishes, furniture, pets, and more.
  • “Everything in a home was manufactured in a factory, wrapped up, and then it’s in your place to off gas.” (00:45)

2. Mike Feldstein’s Background & ‘Aha’ Moment

• Disaster Restoration Roots:
  • Wildfire, flood, hurricane, and toxic mold clean-up expert.
  • Saw firsthand spikes in health problems after disasters (e.g., asthma, autoimmune flares).
• Home vs. Disaster Remediation:
  • “When we would clean a home, you’d clean two things: surfaces and air. … So many people are focusing only on the surface and they're missing air.” (02:09)

3. What’s in “Toxic Air”? — The Science of Particulate & Chemical Contaminants

Particulate Matter (PM2.5) and VOCs

• PM2.5 Explained:
  • “PM2.5 is particulate matter that is 2.5 microns in size. ... It’s small enough to get into your lungs and bloodstream, but it’s too big to get out.” (16:26)
  • Inhaled PM2.5 accumulates, driving inflammation and chronic illness.
• VOCs (Volatile Organic Compounds):
  • Released from paints, carpets, fire retardants—even pajamas and pet care products.
  • “Those chemicals are coming out of everything ... and then we trap it inside.” (05:43)

4. The Parallel with Water Filtration Awareness

• Similar trajectory: 20 years ago, tap water sufficed; now everyone filters water due to microplastics and contaminants.
• “The water awareness is about 20 years ahead of [air] awareness.” (05:35)

5. Common Air Quality Mistakes & Overlooked Sources

• Failure to use ventilation (range hoods, bathroom fans)
• Cooking—even with clean ingredients—releases harmful particulates and polycyclic aromatic hydrocarbons (PAHs). (25:18)
• Cleaning products and pet dander dramatically worsen air quality.
• Carpets, upholstery, and porous surfaces trap and re-release toxins.

6. Health Effects — From Allergies to Cognition

• Cognitive Decline and Alzheimer’s:
  • Louisa references a major US study linking long-term PM2.5 exposure to increased dementia rates: “188,000 new cases of dementia per year in the US are attributable to PM2.5 exposure.” (17:49)
• Asthma, Allergies, Sleep Problems, & Snoring:
  • Feldstein: “If you have a pet, your air... is five to ten times dirtier than outdoor air. Pets double and triple that again.” (50:19)
  • Indoor air pollution not only makes allergies and asthma worse, but impairs sleep quality and deep sleep, increasing inflammation and decreasing cognitive performance.

7. Air Cleaning: Myths, Methods, and the Jasper Difference

• Not All Purifiers Are Equal:
  • Most commercial purifiers are underpowered for real results—“kettles trying to heat bathtubs.” (44:02)
  • Air “scrubbing” (what Jasper does) is not the same as incremental “purifying.”
  • “Fan speed three is where the life-changing, undeniable stuff happens.” (31:46)
• Size, Design, and Functionality:
  • Larger, industrial-style units (like Jasper) offer exponentially more effective cleaning.
  • “One Jasper would be like having six or seven little air purifiers.” (33:17)
  • Cylindrical, steel designs with 360° intake and upward venting work best.
• Real-time Feedback:
  • Built-in sensors and apps let users see air quality spikes and improvements in real time—essential for transparency.

8. Practical Tips and Surprising Insights

• Hotels: Hotel air is often especially bad due to harsh cleaning agents and stagnant HVAC. Feldstein travels with his Jasper for this reason.
  • “Hotels have so much mold problems sometimes they’re ripping down entire hotels … because they turned off the airflow.” (22:03)
• Cooking: Cooking always spikes air particulates—even when using “clean” pans/oils.
• Particle Counters: Easily accessible, allow you to see spikes and trends.
• Pets: Act as “blanket versions of shoes,” bringing in outdoor contaminants and distributing them inside—especially cats with litter and dogs as “sponges.” (49:58)
• Shoes Off Policy: Essential to keep floors and air cleaner.
• Bathroom Fans/Range Hoods: Run them for at least two hours after use to ventilate moisture and chemicals and reduce mold risk. (47:49)
• Change Filters Regularly: Even if they “look” clean, they’re saturated; swap out every six months. (46:35)
• Optimal Placement: Best place for an air filtration unit is the bedroom (sleep) and one in the main living/cooking area.

9. Measurable Results — Sleep & Wellbeing

• A sleep study with OURA rings showed 25 minutes more sleep per night and 18 more minutes of deep sleep with Jasper in the bedroom at high speed.
  • “30% of the people who were snoring, stopped snoring.” (39:49)
• “Sleep is healing time.” (19:41)

10. Action Steps for Listeners

• Understand that bigger is better—choose an air “scrubber” not just a “purifier.”
• Look for units with steel construction, 360° intake, upward venting, and robust, multi-stage filters.
• Track sleep, snoring, and air quality data for measurable improvements.
• Use bathroom and kitchen ventilation effectively; avoid candles and scented products.
• Enforce a shoes-off rule indoors, and be extra vigilant if you have pets.
• Replace filters on schedule—don’t rely on appearance.

Notable Quotes and Memorable Moments

• On Indoor Air:

  “If people took the average sample of air that they're breathing right now and you put it under a microscope, you would be shocked at what you're breathing all the time.”
  —Mike Feldstein, (00:00; 09:48)

• On Mold & Testing:

  "There's mold everywhere. … when you test for mold, you test indoors and outdoors, because mold is omnipresent. It's just something that's in our environment."
  —Mike Feldstein, (10:22)

• On Cooking:

  “When you are cooking, you have high heat and you have protein. … So new chemical reactions are happening. … If you don’t open your windows, have really good ventilation, or scrub the air, you’re really polluting your indoor environment.”
  —Mike Feldstein, (25:18-28:43)

• On the Role of Nature:

  “Trees are the original air purifier. Let's not get it twisted. Jasper is not the ultimate solution. … It’s nature that's cleaning our air. And hopefully there's a world where we don't need machines to scrub our air anymore.”
  —Mike Feldstein, (36:37)

• On Pets:

  “A dog is a blanket version of a shoe.”
  —Mike Feldstein, (50:21)

Invisible toxins are an everyday reality, but awareness—and action—can yield profound wellness benefits. Whether through better ventilation, filtering, or product choices, small changes can protect your home’s “lungs.” As Feldstein says:

“Ignorance is not always bliss. … Better to be aware than unaware.” (50:21)
