Sleep Quality
Sleeping well shouldn't be a challenge
We spend about a third of our lives asleep — yet often overlook the air we breathe at night.
In closed bedrooms, air renewal slows down, fine particles accumulate, and humidity builds up. Over time, this makes your sleep less restorative, as it can cause micro-awakenings, nasal congestion, or that feeling of “heaviness” when you wake up.
Improving air purity at night isn’t only about comfort. It helps your body rest and recover naturally — so you wake up with a clearer head and easier breath.

How the air your breathe impacts your sleep
At night, most bedrooms are sealed to keep warmth and quiet — but that also traps what’s already in the air. As we breathe, we release carbon dioxide and humidity. Dust, pollen, and microscopic particles from bedding, clothing, or furniture stay suspended longer because there’s little air movement to disperse them.
Throughout the night, this creates a subtle feeling of “stale” air: it may not smell bad, but it feels heavier, drier, or stuffier. Some people wake up with a congested nose, an irritated and dry throat, or mild headaches without realizing it’s often linked to air quality rather than sleep duration.
A room that looks clean can still hold fine particles and irritants invisible to the eye — and because we breathe most deeply during sleep, the body becomes more sensitive to them.
Why most night-time solutions don’t address the real issue
People often try to improve sleep by acting on light, sound, or temperature — but overlook the air itself
Opening a window helps, but only when outdoor air is clean and the temperature comfortable. The trade-off often means noise, drafts, or pollution entering the room.
Essential oil diffusers or sprays can create a pleasant scent, but they add volatile compounds to the air instead of purifying it. They cover the lack of purity, but don't fix it.
Filter-based purifiers are effective, yet their fan noise can disturb rest — and their filters require regular maintenance and disposal.
The result is a dilemma: cleaner air often comes at the cost of silence, and silence often means stagnant air.
How we use a natural phenomenon: air ionization
Have you ever thought that when it rains, after a storm or near a waterfall, the air feels especially fresh and pure?
That's thanks to a natural event: the air being cleaned by negative ions.
In short, when water drops break, they create negative ions, which attach themselves to airborne particles (from dust and pollen, to pollutant and fine particles).
These harmful particles become charged with negative ions, and they start being attracted by bigger electrostatic masses. Indoors, that means furniture, walls, and in most cases, the ground. So as they get charged with more and more negative ions, they're attracted away from where you could breathe them.
That's how negative ions remove harmful particles in the air, leaving it as pure as possible.
Our ionizer air purifiers recreate this natural process indoors.
Instead of pulling air through a disposable filter, like most air purifiers, ours release negative ions to neutralize pollutants directly in the air / or attract them into a cleanable compartment.
This means there’s no noisy ventilation, and no filters to replace — just cleaner air that feels lighter and fresher, like in nature.
They Experienced the Effectiveness of TEQOYA Air Purifiers
Since the arrival of Teqoya, I have regained better sleep quality [...] Also, the air in our home is free of any form of pollution, and we clearly feel the benefits.
I have been a loyal user for many years. Thanks to your T200 and E500 purifiers, we have significantly improved indoor air quality by effectively controlling fine and ultrafine particles. On very polluted days, we also limit VMC air extractions to relieve our devices.
We live in a highly urban area, close to various obviously polluting zones. [...] The results are FAR beyond our initial expectations!!! Pierre now snores only occasionally, it's clear that TEQOYA plays a big, if not total, role… We feel that our sleep is deeper, more peaceful, and more restorative overall.
A device that is revolutionary for me. I saw the magic of ions acting on my health from the first days, as I am a sensitive allergy sufferer. I no longer had bloody noses as usual. With purer air than in rooms without equipment, my sleep was deep and truly restorative for 5 to 7 hours per day.
My wife has always had bronchitis. [...] We feel that the indoor air of our home is increasingly fresh, my wife feels better, and I, who often suffer from insomnia and sometimes need sleeping pills to avoid waking at night, now sleep much better.
I want to express that I am extremely grateful to the inventor of this technology, as I can now sleep with the window closed without waking up in the middle of the night suffocating!
I am a long-haul truck driver, so I sleep in my truck. At first, I only ran the Tip4 while driving. I slept poorly, with restless nights. I then decided to leave it on to test. I realized I slept much better, woke up less at night, with calmer, more restorative sleep.
I bought a first Tip9 based on the promise of healthier air from a dear friend. I installed it in the bedroom. Within a few days, imperceptibly, my partner and I were surprised to wake up each morning feeling like we had had a very good, restorative night’s sleep.
The air around me felt renewed, fresher, more invigorating. And I sleep better, even with the window closed.
Our technology is used by health professionals
When we started TEQOYA in 2015, it was backed by more than 15 years of research and many proven institutes. You can learn more about how our technology works by clicking here.
Our founder, Pierre, wanted to first help his asthmatic daugther, then the most people possible, breath clean air. Turns out most health professional share this goal, and many adopted TEQOYA across their establishments.
Today, our purifiers are present in hospitals, at several nursing homes, and in numerous consultation and waiting rooms of health professionals.

About TEQOYA
Pierre was looking to help his daughter, who suffered from asthma.
He discovered the benefits of an air ionization system developed by Jacques Breton, an eminent Professor, and member of the New York Academy of Sciences, who spent more than 15 years studying air ionization.
This systems works by emitting negative ions, without generating ozone or any chemical substance, to neutralize polluting particles. It was then proven by research, but not offered to the general public.
But in 2014, a huge peak in air pollution happened in Paris. This became the trigger who motivated Pierre to create TEQOYA, and share this technology with as many people as possible.

Since then, TEQOYA has been receiving many awards, support, and was chosen by many brands and institutions. But most importantly, it has helped thousands of people breath clean air.
