Therapy Air® iOn Black
Filter, purify & enrich the air you breathe
Control dust, temperature and humidity in the home or in the office while eliminating airborne pollutants with Zepter’s Therapy Air®iOn.
Our advanced 5-filter system — including HEPA, antibacterial, anti-allergenic, and activated carbon layers — removes up to 99.99% of pollutants from the air. The result is purified, therapy-grade air that is free from viruses (including SARS-CoV-2), bacteria, and toxic substances, ensuring a cleaner and healthier environment.
German experts have named TherapyAir® iOn the best air purifier among global brands for four consecutive years. The prestigious German laboratory GUI Lab has issued a certificate confirming that this device also eliminates the SARS-CoV-2 virus from the air.
Energy of negative Ions
Air in our homes is 10 times more polluted than outside air.
Throughout a typical day, people tend to spend up to 90% of their time indoors, where air quality often fails to meet even basic health standards.
TherapyAir® Ion systems combine advanced multi-layer filtration and ionization to effectively remove dust, allergens, and airborne viruses.
Therapy Air®Ion generates 1,200,000 negative ions/cm3, i.e. — 5 times more than found in the healthiest natural environments, like those near massive waterfalls — bringing nature’s purest environments into your home and office.
Ionized air boosts the immune system, increases productivity and reduces stress.
Key Benefits
Active Filtration
Most air purifiers work passively—they simply wait for air to be drawn into them. TherapyAir® Ion works actively, releasing negative ions that function like an “Invisible Patrol.” These ions move throughout your living space, attaching to and neutralizing viruses, sand dust, and pet dander before you have a chance to breathe them in.
5x more negative Ions
Therapy Air®Smart generates 1,200,000 negative ions/cm3, i.e. — 5 times more than found in the healthiest natural environments, like those near massive waterfalls — bringing nature’s purest environments into your home and office.
Better Sleep Quality & Focus
Negative ions and cleaner air help improve sleep by reducing airborne irritants and creating a fresher, more relaxing breathing environment that supports deeper, more restful sleep. Improved indoor air quality boosts the immune system, increases productivity and reduces stress.
Awarded & Certified
German experts have named TherapyAir® iOn the best air purifier among global brands for 4 consecutive years. The prestigious German laboratory GUI Lab has issued a certificate confirming that this device also eliminates the SARS-CoV-2 virus from the air.
Easy Filter Replacement
The filter is designed for quick and easy replacement, making maintenance simple and hassle-free.
10-years Warranty
Most purifiers come with simple 2 years warranty. We provide a 10-year warranty to ensure long-term reliability and peace of mind. Invest once, breath for years.
Increase immunity & productivity
A study by William Fisk from the California Lawrence Berkeley National Laboratory concluded that better indoor air quality boosted worker productivity, leading to estimated savings up to US$200 billion per year. If the blood does not have a good supply of oxygen, the brain will very quickly become tired, losing its ability to think clearly.
As the thinking becomes confused, the mind becomes very susceptible to depression. This, in turn, has a depressing effect on the whole system, including the body’s immune system, leaving the body in a condition of being more susceptible to sickness and disease.
Your defence against polutants and allergens
Dangerous particles which can be found in the home include pollutants, allergens, pollen and mould. We also have to contend with volatile organic compounds (VOCs), which are the chemical compounds that can become hazardous air pollutants and are released from paints, cleaners, solvents, and other household products that can contribute to poor air quality.
During the cold and flu season, the air quality in your home can also affect how frequently you and your family catch the flu or a common cold.
