This protects both the building substance and your health.
Interior air dehumidification thanks to condensation technology. Condensation drying, also known as cold drying, is the most commonly used method of air dehumidification for the private or professional sector. The core of the CA-708 Smart condensation dehumidifier is the cold compressor. The device works in recirculation mode with closed windows and doors and is particularly economical with electrical energy.
Five filter technologies 1. Active carbon filter activated carbon neutralises smoke, chemicals, gases and odours, prevents the growth of bacteria, viruses and mould. 2. Pre-filter. 3. True HEPA filter H13 according to EN 1822 with nano silver coating. Cleans 99.97% of all suspended matter up to 0.3 microns (0.3 µm) from the air. 4. Permanent UV-C lamp / 254 nm. 5. Ionizer capacity > 3,000,000 negative ions/cm³

With the 2-in-1 function for dehumidification and air purification, the CA-704 Smart ensures an optimal indoor climate all year round: when the set relative humidity is reached, the dehumidification stops. With its continuous air purification function, the multifunctional Clean Air Optima CA-704 Smart frees the room air from allergens, mould spores, annoying pet hair, pollen, (fine) dust and odours throughout the year.
Tumble drying: the Clean Air Optima CA-704 Smart dehumidifier with 2-in-1 system for dehumidification and air purification supports the drying of your laundry. The high dehumidification performance with high fan speed ensures good air circulation in the washroom. The running dehumidifier also releases some heat to the washroom. This combination creates a laundry drying effect.
Thanks to the five-fold filter technology (activated carbon filter, pre-filter, TRUE HEPA filter H13 according to EN 1822 with nano silver coating, UV-C lamp and ioniser), clean breathing air is created. Per day, this powerful condensation dehumidifier removes 10 litres of moisture from the interior air at an ambient temperature of 30°C. The moisture is collected in a large water tank with 3 litre capacity.
Condensation Dehumidifier The most common method of dehumidification is the condensation dehumidifier, also known as compressor dehumidifier. These electric dehumidifiers are used to eliminate moisture in homes, bedrooms, offices, holiday homes, caravans and trailers. The great advantage of the compressor-controlled condensation dehumidifier is that it requires 25-60% less power than an adsorption dehumidifier.
CA-704 Smart has an automatic defrosting function. As soon as the sensor signals a temperature below the set value, the defrosting starts automatically and also stops automatically. During the defrosting process, the evaporator is made ice free again by stopping the cooling process and turning on the fan. As a result, the ice melts. When restarted, the dehumidifier automatically continues to work and preserves the settings.

Rotating swirling spiral airflow The rotating swirling spiral air flow creates a reflective effect on walls, ceiling and floor. This distributes air flow much better throughout the room compared to conventional fans.
Automatic horizontal oscillation 80°. The Clean Air Optima design circulator fan CA-404B has a large automatic rotation angle of 80°. Vertical oscillation 180°, adjustable by hand. The upper part of the Clean Air Optima Design circulator fan CA-404B has a generously sized vertical oscillation of 180°, which can be adjusted by hand for maximum effectiveness.
Air purification by ioniser. The integrated ioniser generates negative oxygen ions, so that the room air is cleaned and refreshed in addition to the cooling fan effect. Negative ions hang on dust particles, microorganisms and other unwanted substances in the air and connect them together. The particles become heavier than air and sink. This filters the air and neutralises odours.
Active aerodynamically shaped fan blade. Thanks to the innovative, actively aerodynamically shaped and deeply inclined fan blade, the fan in a unique spiral shape circulates the air much faster than a conventional fan!

True HEPA filter H13 according to EN 1822 with nano silver coating. Cleans 99.97% of all suspended matter up to 0.3 microns (0.3 µm) from the air. The HEPA filter is the most effective air filter for removing (fine) dust, cigarette smoke and pollen allergens, mould spores of other suspended substances. The antibacterial layer of the nano silver coating on the filter eliminates bacteria and mould.
The Clean Air Optima condensation dehumidifier CA-704 is equipped with a built-in hygrostat to measure, control and automatically adjust the relative humidity. The desired humidity can be adjusted between 35 and 80% relative humidity. This dehumidifier is pre-programmed as standard to achieve the optimal humidity of 55% recommended by doctors.
The CA-704 dehumidifier can be used within a wide temperature range between 5 and 32 °C. The moist room air is sucked in by the fan and flows via a cooling register (evaporator). As a result, the moist air is quickly cooled and the excess water condenses out (below the dew point temperature). The condensation moisture drips into the water tank via a collection tray or is directly dissipated via the supplied hose.
Thanks to the slim, tailored design in an exclusive design and the neutral colouring, this compact humidifier fits into any interior. The Clean Air Optima condensation dehumidifier CA-704 with built-in hygrostat is the perfect solution for automatic dehumidification. Simply adjust the desired humidity and this efficient dehumidifier does the rest.
