The new NK300 provides superior air cleaning in large rooms up to a maximum 75m2. The 360 degree True HEPA filter removes over 99.97% of all airborne pollutants down to 0.3 microns and has the added benefit of an integral air quality sensor for detecting pollution levels and adjusting its settings automatically to deal with them. A clever lighting system on the top of the unit also changes colour in line with the air quality giving the user instant visual confirmation.

New for 2017 with 4-Stage all-in-one 360 Degree Hepa Cartridge.

The new Winix NK300 combines a modern design and a 4-Stage cleaning system. At the heart of the machine is a 360 degree all in one filter cartridge combing a hair collecting pre-filter, Cleancel deodourising carbon filter, 99.97% true HEPA Filter and Plasmawave Technology all combining to offer superior control of household allergens, dust and odours.

Internal Smart Sensor with Colour Changing Pollution Indicator
The NK300 is constantly assessing the amount of pollutants, allergens and odours in the air and adjusting its own fan speed automatically to stay on top of things.  Rising levels of pollution are indicated by a clever lighting system on the top which changes from Blue (good quality) to Amber (fair quality) to Red (Poor quality).

Ideal for Larger Rooms up to 75m2.
If your room is fairly large, perhaps encompassing a lounge/diner then the NK300 is the ideal choice to ensure the whole room gets purified as quickly as possible. The large fan motor provides sufficient airflow even on lower (quieter) fan speeds to draw all the air in the room through the filters up to 5 times every hour.

12 Month Filter Life with Cleanable Pre-Filter
The large diameter HEPA filter inside the NK300 provides such a large filtering surface area that it should last around 12 months between filter changes. The fine mesh, cleanable pre-filter collects the majority of the larger particles leaving the HEPA filter to deal with the much smaller (more harmful) sub micron pollutants. This prolongs the life of the HEPA filter by up to 500%.    

Small Footprint for Easy Placement
Although the NK300 is quite large in stature, being a tower design it has a fairly small footprint and therefore takes up less floor space than may similar powered units and like all our Winix models, we provide a full two year new for old warranty with the NK300 , although this is unlikely to be required it is good to know it is there!

You may also like to consider the NK300's Smart sibling, the NK305 which includes Wi-Fi connection and full Smartphone/Tablet control.
