Cet été j'avais du mal à dormir à cause de la chaleur. Depuis deux semaines, je dors une nuit complète avec le mode nuit. L'air dans la chambre est nettement plus agréable.

Product specifications
Premium portable evaporative air cooler — not an air conditioner. HEPA H13 filtration (99.95% of PM2.5 particles), Wi-Fi + Bluetooth control, 5.5" touchscreen, 6 L tank for 22 hours of runtime. Designed for those who want filtered air quality and smart control in a premium aluminum design.
Important — this is an evaporative air cooler, not an air conditioner. The device lowers the perceived temperature by 3 to 6 °C within a radius of 1 to 2 meters around the air outlet. It does not cool an entire large room like a compressor-based air conditioner and does not replace a split air conditioner. Power consumption: 145 W (approx. 10× less than an air conditioner).
How does it work?
Simple principle: water (and, if you wish, ice cubes) is circulated over a filter through which the fan blows air. As it evaporates, the water absorbs heat — the outgoing airflow is noticeably cooler than the ambient air. It is the same physics that makes a sea breeze pleasant. No compressor, exhaust hose, or installation.
Who is it designed for?
The Signature Ultra 2026 is designed for discerning households — Haussmann-style apartments, modern lofts, and designer interiors — that want to combine the comfort of a cooled airflow, HEPA-filtered air quality, and aesthetic integration. Its HEPA H13 filtration captures 99.95% of PM2.5 particles, allergens, pollen, and bacteria in the airflow area. Its Wi-Fi control via the dedicated app lets you schedule the ambiance before you even get home.
Why this price?
Below, you will find generic air coolers without HEPA filtration, Wi-Fi, or an air sensor. By contrast, a filtering split air conditioner is a different category of product (installation, drilling, compressor, €1,500–€2,500 + installation). The Signature Ultra is deliberately positioned between the two: the best of an evaporative air cooler, with the filtration of an air purifier and the convenience of an app. No construction work, delivered to your home within 7 to 10 business days.
Key features
- HEPA H13 filtration — captures 99.95% of PM2.5 particles, pollen, allergens, and bacteria in the airflow area.
- 2.4 GHz Wi-Fi + Bluetooth 5.0 — control it from the iOS / Android app, wherever you are in the house.
- Dedicated app with scenarios — schedule scenes (Sleep, Wake-up, Evening) that activate automatically.
- 5.5" LCD touchscreen — displays temperature, humidity, air quality, and active mode in real time.
- Integrated PM2.5 + humidity sensor — the device adjusts its power according to the ambient air.
- Ultra-quiet 33 dB night mode — the quietest in our entire range.
- Cold Air Boost — intensified cooled airflow for 30 minutes upon arrival.
- Premium brushed aluminum frame — high-end finish, 110 cm tower design.
- Silicone anti-vibration feet — absolute silence on hard floors.
- Adjustable ambient LED — white or bluish light strip with variable brightness.
- 6 L tank + auto-clean — 22 hours of runtime, with automatic water-tank cleaning.
Limitations to know (transparency)
- This device is not an air conditioner — it cools the blown airflow; it does not lower the overall temperature of an enclosed room.
- It is less effective in very humid air (above ~70% humidity) — evaporation slows down. Maximum performance occurs in dry air and dry heatwaves.
- It does not replace air conditioning in very large rooms or for professional use.
- For maximum effect: use very cold water or ice cubes in the tank, point it directly at you, and leave a window slightly open to renew the air.

Frequently asked questions
Does it really cool or is it just a fan?
No — this is not just a fan. The evaporative system draws water from the tank, absorbs the heat from the room air, and blows out air up to 8°C cooler than the room. Concretely: the felt temperature drops 3 to 6°C within a 1-2 meter radius, in 30 to 40 minutes. For a bedroom or office of 15-25 m², the Lite Night or Lite Prestige is more than enough. For a living room or large space up to 44 m²: the Pro 9000 Élite or Frost 9000 Smart Max — our most powerful models.
Do I need a window or exhaust hose?
No — no hose, no hole in the wall, no landlord approval needed. Plug in, fill the 6 L L tank, switch on. That's why renters, Airbnb hosts and van-lifers pick our cooler right away. Zero installation, zero hidden costs, mobile from room to room.
Is it quiet enough at night?
This model runs between 33 and 56 dB. At the lowest speed (33 dB), it's whisper-level — quieter than a ceiling fan. The Lite Night is our model specifically optimized for sleep: customers report barely hearing it at 40 cm from the bed. If silence is your absolute priority, the Lite Night is the obvious pick.
How much does it cost to run?
145 W when running — around 10 to 18 €/month for 8 h/day of use, depending on your rate. That's 5 to 10 times less than a split AC (60-120 €/month). A Coldest Breeze uses less than an old fridge. That's why we call it 'the frugal AC'.
What room size is this model for?
This model is optimized for 38-42 m² (premium coverage). For larger spaces (living room, open plan up to 44 m²): Pro 9000 Élite or Frost 9000 Smart Max. For a standard bedroom: Lite Night, Lite Prestige or Deluxe Titan. For rooms needing air filtration (allergies, pets, city pollution): Signature Ultra with medical HEPA H13 filter.
When will I receive my order?
Free shipping across Europe in 8 to 10 business days. We ship within 24-48h with tracking via DHL, DPD or local carriers. In peak season (July-August), allow 2-3 extra days — you're notified at every step by email.
