Hello, I'm Eszter

The story behind PureNest

I'm a Building Biology consultant, a mom, and someone who spent years trying to understand why my body was falling apart — until I finally looked at the place I spent the most time: my home.

For years I felt terrible — chronic fatigue, brain fog, sinus issues that never fully resolved. I saw practitioners. I ran tests. I spent over $60,000 on treatments, supplements, and specialists. And none of it stuck.

The breakthrough came when I finally moved out of a home I hadn't realized was making me sick. Within weeks, I started feeling like myself again. That was the moment I discovered Building Biology — the science of how our living spaces affect our health. I learned that the water I drank, the air I breathed, the materials around me — they were all part of the problem I'd never considered.

Once I fixed those root causes, everything else finally worked. That's the gap I built PureNest to fill: a clear, step-by-step path so other families don't have to spend years and thousands figuring this out themselves.

My story

For years, I lived in a home I didn't realize was making me sick. The symptoms were easy to explain away — fatigue, sinus trouble, brain fog. I was a mom with two kids. Of course I was tired.

I spent over $60,000 trying to feel better. Specialists. Tests. Supplements. Some things helped for a while. Then the exhaustion would come back, and I'd wonder what I was doing wrong.

The truth hit me like a wall when I finally moved out. Within weeks, I felt like myself again. It was that stark. And it led me to Building Biology — the science of how our homes affect our health.

That's when I discovered the missing piece: water and air. These are the two things your family consumes most, every single day — and most people never think to look at them. The water flowing through your pipes, the air trapped inside your walls, the off-gassing from your furniture — those were the gaps no amount of supplements or appointments could fix.

Once I addressed those root causes, everything else started working. Treatments actually worked. Sleep improved. The fog lifted.

What I learned, I now teach to families who are where I was: exhausted, spending money trying to feel better, and not realizing the answer was partly in the room around them.

PureNest is the guide I wish someone had handed me. Step by step, room by room, no expensive gadgets required — just a clear path to a home that actually supports your family's health.

8 Modules

What You'll Learn

A room-by-room system that turns "where do I even start?" into a clear, affordable action plan. Each module builds on the last — so nothing feels overwhelming.

1

Foundation Mindset

Understand where toxins actually hide in your home and why they matter. Learn to read labels, spot greenwashing, and build a personalized detox roadmap — on any budget.

2

Sanctuary Kitchen

Tackle the most important room first. Swap cookware, storage containers, and cleaning products with safe alternatives — without throwing everything out at once.

3

Recovery Sleep

Transform your bedroom into a true recovery zone. Address mattress off-gassing, bedding materials, and air quality so your family sleeps deeper and wakes refreshed.

Living Space Revival

Detox your living room, play areas, and common spaces. From furniture off-gassing to flooring choices — learn which changes give you the biggest health return.
