Winix NK100 Review

The Winix NK100 is just one of several tower air purifiers offered by the Winix brand.

While it doesn’t have as many advanced user features as the other models (Winix NK105 and Winix QS), this unit does include the same powerful air cleaning performance as those air purifiers.

Even though this air purifier is simpler when it comes to technology, the upside is that this unit is much easier to use and understand.

So, if you just want a simple air purifier that cleans the air well, this may be exactly what you’re looking for.

Winix NK100 Air Filter Types

To start this Winix NK100 review, let’s look at the various filter types that this air purifier has.

Like the other similar models offered by this brand, the Winix NK100 tower air purifier has a four-stage air filtration system:
Winix NK100 Tower Air Purifier

  • Pre-filter – As the air passes through the pre-filter, it captures large particles, including dust, hair, lint, and dirt.
  • True HEPA Filter – This powerful filter removes 99.97% of airborne particles that are as small as 0.3 microns in size. This includes pollutants such as pollen, mold spores, bacteria, pet dander, and ultrafine dust.
  • Activated Carbon Filter – This filter was added to remove odors from the room. It can eliminate tobacco smoke, pet odors, and cooking smells. It even has the ability to remove harmful airborne chemicals that might be polluting your indoor air, such as volatile organic compounds (VOCs).
  • Winix PlasmaWave – This feature makes the Winix brand stand out from the rest, and it has the ability to make the air in your home incredibly clean and fresh. It uses special technology to put air into a plasma state that reacts with water vapor to break apart pollutants like bacteria, viruses, and VOCs.

The best part about this air filtration system is that all of the filters are combined into a single 360° all-in-one filter design.

So, replacement is easy. Just take out one dirty filter and replace it with a clean one every 12 months.

Winix NK100 Room Size Coverage

As with most of the air purifiers from this brand, the Winix NK100 tower air purifier was created for medium-sized rooms.

Thus, the Winix Nk100 air purifier can clean the air in rooms up to 320 square feet in size.

That amount of power makes it good for areas such as:

  • Bedrooms
  • Living rooms
  • Home offices
  • Workplace offices
  • Apartments
  • Children’s rooms
  • Small finished basement areas

Here's how other Winix air purifiers we've reviewed compare:

As you can see, Winix has found a sweet spot for room size coverage that meets the majority of people's needs and applied it to most of their air purifier models.

Winix NK100 ACH Rating

The Winix NK100 works hard to remove particles from your indoor air, and how often it does this is referred to as the ACH rating.

ACH is short for “Air Changes per Hour” and this essentially tells you how many times per hour the air purifier can recycle the air.

The Winix NK100 has a 5x ACH rating.

That means this air purifier can clean the air in a 320 square feet room once every 12 minutes or five times each hour.

Winix NK100 CADR Rating

There are three common airborne pollutants that every home, office, or apartment contains: smoke, dust, and pollen.

And the Association of Home Appliance Manufacturers (AHAM) puts air purifiers to the test against those contaminants.

The results of that test are referred to as the CADR rating or “Clean Air Delivery Rate”.

The closer the CADR numbers are to the room size coverage of the air purifier, the more effective the unit is at removing those particles.

The Winix NK100 CADR rating is as follows:

  • Dust: 221
  • Pollen: 218
  • Smoke: 207

These are good CADR ratings.

What you want is an air purifier with CADR numbers that are at least 2/3 the square footage size that it’s rated to cover.

And the Winix NK100 meets that air quality standard.

Winix NK100 Features

  • Smart Sensors – These sensors monitor the air quality of the room to detect airborne pollutants and then send a signal to the air purifier to automatically adjust the fan speed to remove those pollutants.
  • Automatic Mode – This mode works in conjunction with the Smart Sensors to deliver the cleanest air possible at all times. No user interaction is needed to adjust the fan speed settings.
  • Air Quality Indicator – This ring of light on the top of the unit gives you real-time information on the quality of the air. The LED light changes colors from blue (good), amber (fair), and red (poor).
  • 4 Fan Speeds – If you want to control the Winix NK100 tower air purifier manually, you can choose from four fan speeds: low, medium, high, and turbo.
  • LED Auto-Dim Feature – When the lights in the room dim or are turned off, this sensor will notice and adjust the brightness of the LED lights on the control panel so they don’t disturb you while you sleep or watch TV in a dark room.
  • Filter Replacement Indicator – These lights will let you know when it’s time to replace the filter so you can always have purified air circulating throughout your space.
  • Child Lock – The feature ensures that a small child (or pets) can’t change the settings on your Winix NK100 tower air purifier.
