Main highlights

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.

micro-organisms and other unwanted particles and connect them together. The particles become heavier in this way and sink to the ground or are filtered out of the air by the ioniser.
The ultrasonic atomisation of the water is carried out by a small high frequency vibration plate (membrane) in the water basin. The high frequency technology of the membrane ensures that the microfine water is converted into cold or warm mist that is released into the ambient air by a soft blower air flow. Humidification performance humidifier CA-607B min. 120 ml/h - max. 480 ml/h
Heating element for warm humidification - The humidifier CA-607B has a heating element for warm humidification. When the heating element is turned on, the mist production is most efficient and the humidity is increased the fastest. The heating element prevents bacteria formation in the water and keeps the room temperature even in the winter months.
Aromatherapy aims at maintaining and strengthening health and healing certain ailments.
Air humidification with UVC sterilisation - The high frequency technology of the membrane ensures that the micro-fine water is converted into mist, which is passed past the UVC lamp by a soft blower air flow to sterilise the mist and then released from the room to the ambient air. The UVC lamp also contributes to the destruction of bacteria and viruses and thus prevents odours in the water.

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.
