4 Stage Filtration System

Like any other air purifiers with lots of automated features, Winix NK1005 uses four stage filtration.

In the pre-filter, all the big particles are cleaned, which then makes the main filter intact from such large pollution. Overall air purifiers with pre filters do a better job than the ones without pre filter.

The active carbon filter is the stage where all other chemicals are removed. It can remove smoke, bad odor, dust, formaldehyde, and many other toxins that can cause health problems. This unique layer is what gives Winix NK1005 the power to remove VOCs and bad smells so fresh and free from any harmful chemicals you can breathe easily again.

The third stage but not least is the true HEPA filter. With that filter, Winix NK1005 air purifier captures 99.97% of all contaminant particles down to 0.3 microns. True HEPA is also the main filter which will remove everything you don’t want to bread, including allergens as pollen, mold spores, and dust. 

PlasmaWave is the last stage which works at a molecular level without releasing any ozone in the room. On such a molecular level, odors, chemicals, allergens, and particles are broken down for easier capture.

Large Room Air Purifier

NK105 is best used in 320 square feet room, and in such sized room, it has magnificent performance. CADR on dust pollen and smoke is from 207 up to 221 which is a decent rating for this sized air purifier.

Four Speed Option

You can choose one of the four speeds available. The speed you choose is in correlation with the air pollution, and if you think the air is heavily polluted, you should select Turbo speed. 

If you don’t want to bother with speed selection, you can turn on auto mode and use smart sensors to track air pollution in the room. Air pollution in the room is measured in three levels, and the speed of the air purifier will change according to the air pollution level. An air purifier will make all the adjustments completely automatically.

One of the Best Designs

WinixNK105 is a beautiful air purifier which will fit in every room. It is tower-shaped air purifier that can suck air from all sides, and because of that, it is best to place it in the middle of the room from where it can suck air from all angles. There is no worry about esthetics because even if you do place it in the middle of the room, the whole room ambient won’t be destroyed. In fact, such a marvelous device will lift the room decor to a whole new level.

Auto Dim Light Feature

Winix put special LED lights in NK105 model which can automatically auto dim when in the dark. The whole system checks the ambient light in the room and then adjust the brightness of the display. Most mobile phones on the market have such feature which auto adjust the brightness of the screen.

Filter Replacement

Replacing filter is easy as taking the old filter out and putting the new one in. Thanks to real time filter monitoring, you will know exactly when is the best time to replace filters. Carbon filters need to be replaced every six months while the True HEPA filter needs to be replaced once per year.
