Winix NK105 Air Filter Types

To start this Winix NK105 review, let’s take a look at the filter types included in this air purifier.

The Winix NK105 tower air purifier has a four-stage air filtration system:
Winix NK105 Tower Air Purifier

  • Pre-filter – The pre-filter captures large particles, including lint, dust, hair, and dirt.
  • True HEPA Filter – This filter has the ability to remove 99.97% of airborne particles that are as small as 0.3 microns in size. This includes particles such as mold spores, pollen, pet dander, bacteria, and ultrafine dust.
  • Activated Carbon Filter – This filter removes odors. It can capture pet odors, tobacco smoke, and cooking smells. It can even trap harmful airborne chemicals that might be polluting your indoor air, including volatile organic compounds (VOCs).
  • Winix PlasmaWave – This feature is unique to the Winix brand, and it works hard to make the air in your home pristine. The special technology transforms the air into a plasma state where it reacts with water vapor to break apart pollutants, including viruses, bacteria, and VOCs.

This air filtration system is combined into a single 360° all-in-one filter design, making replacement easy.

Every 12 months, all you have to do is take out one dirty filter and replace it with a clean one.

As for the PlasmaWave feature, it never needs to be replaced since it works outside of the filters.

Winix NK105 Room Size Coverage

Most of the air purifiers manufactured by the Winix brand are for use in medium-sized rooms, and the Winix NK105 tower air purifier is no exception.

The Winix NK105 air purifier works ideally in rooms up to 320 square feet in size.

That makes this air purifier good for the following rooms:

  • 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 NK1050 ACH Rating

The Winix NK105 is a fast-working unit.

In fact, it’s one of the fastest air purifiers for cleaning your indoor air.

The speed at which an air purifier can clean the air inside a room 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 same room 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 NK105 CADR Rating

Every building contains some level of these three common airborne pollutants: smoke, dust, and pollen.

And your air purifier should be good enough to remove those contaminants.

The Association of Home Appliance Manufacturers (AHAM) is an organization that puts air purifiers to the test against those pollutants.

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

The Winix NK105 CADR rating is as follows:

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

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 NK105 has good CADR ratings since these measurements are at least 2/3 the square footage size that it’s rated to cover, which is what you want to see in a top air purifier.

  • Filter Replacement Indicator – These lights let you know that it’s time to replace the filter so that you always have clean, fresh air circulating throughout your space.
