Negative ions

After many measurements and research of quality products available in the world, our office ETUDES & VIE decided to import two brands of ionizers and air purifiers.

This is our range of high performance TEQOYA ionisers and air purifiers. After reviewing the existing ionisers on the market, we came to the conclusion that the French Teqoya range had built their reputation over the years on product quality and technological research. No ozone and nitrogen oxide emissions!
Discreet and silent, the TEQOYA 200 air purifier is ideal in a bedroom or office. It can be placed on the bedside table in your bedroom or your children’s bedroom to enjoy the benefits of negative ions while you sleep. It effectively fights particles, allergens and bacteria in the indoor air. Lightweight and compact, it can also be taken anywhere you go.
The TEQOYA 450 home air purifier is ideal for use in social areas or reception areas. It fits perfectly in large rooms (living room, dining room, meeting room) where you like to relax and spend time. Its design allows it to fit into any living space. Without filters, it is easy to use and requires no maintenance. It is also very popular in medical and paramedical practices or dental offices.
The TEQOYA Nomad car air purifier goes everywhere with you and offers you clean air in your car. Filter-free and eco-friendly, it effectively combats pollutants, bacteria, viruses, allergens, cigarette smoke and odours in the cabin. Portable and discreet, the car air ioniser spreads negative ions evenly throughout the cabin.
These ionisers are also virucidal and bactericidal! (*)
