Space has the particularity of clean and disinfect indoor airFor this it includes a pre-filter that retains the largest particles such as animal hair, cuticles and dust; a filter Hepa13 that absorbs particles down to 0.3 μm such as pollen or allergens; an active carbon filter that eliminates bad smells and tobacco smoke; and finally, UV light, which, according to the tests carried out by the firm in its laboratory, eliminates viruses and bacteria.

An added value of this series is that has wifi connectivity for remote control via a dedicated mobile app, which allows –among other advantages– to connect it before arriving home to find a healthy environment upon arrival.

This particular model can cover surfaces of up to 61 m2, for smaller spaces there are solutions: the series Clean covers up to 27 m2, while the series Cube y Dust Cube cover up to 15 m2. Space has a noise level of 21 dB and it should be noted that the Clean Series includes negative ion generator, and has a noise level of 30 dB.

From the company we are launching novelties and solutions for air purification and thus guarantee a healthier environment for people. ‘

They create a more pleasant environment by eliminating odors and also improve comfort, especially for people suffering from respiratory and allergic problems.
