But thanks to it, we are having one device with all of the Smart features which are normally seen in the $600 air purifiers. Now, it’s time for our Winix NK105 Review.

Winix is one of the first brands to make the air purifier history, with no less than 40 years of experience for air filtration. Their air purifiers aim at being the high quality ones, packed with the most modern features and unrivaled air filtration process to challenge any other air purifier brands. They are more well-known in their home country, Korea, together with another giant named Coway. But believe me, the history they have built for the U.S air purifier market can beat, well, lots of native American brands. Today, we are happy to take a look at a solid choice that will meet most buyers’ needs, the Winix NK105 Review.
Winix NK105 Price
If Winix previous line-up never appealed, the Winix NK105 will definitely have something new to awake your interest. This is an air purifier as good as you could hope for, with an impressive and unique design that is continued by the 2020 Levoit’s flagship – Levoit LV-H134, a Winix innovation in air filtration and lots of Smart features.
Those have purchased the Winix NK100 and love the air purifier will of course set an eye on this new Winix NK105. I bet that some of them will regret why not wait more for this Smart device. This is a top-quality air purifier with a high-quality app to control, not like the negligent and bugged apps from Guardian Technologies or even Coway and Blueair.
While the Winix NK100 is unavailable in the official website of Winix America, the Winix NK105 is a great alternative with only $329 as the starting price.
This is a top-end air purifier, the kind that deserves some research and thought before clicking the “checkout” button. However, it isn’t quite as expensive as the Rabbit Air BioGS 2.0, Medify MA-40 or the Alen BreatheSmart FLEX. In fact, if you’re a fan of Winix above all other air purifier manufacturers, you can probably skip this whole review and just buy the thing with our deal below.
Whispering, the price drops to a level you can’t ignore. Yes, it is only $188 from our deal, and it is only for a limited time. You can also look for the Winix C545 as the best alternative, if you prefer the console air purifier type more.

Winix NK105 Design and Size
At first glance, the Winix NK105 doesn’t look like a huge departure from the Winix NK100. There is no obvious difference between the two. Unless you check the additional Wi-Fi button on the Winix NK105’s control panel, you’re unlikely to notice the changes, even if you just put the two back to back.
But this is indeed a great compliment for the Winix NK105, especially when the Winix NK100 is Red Dot Design Award and Good Design Award winner. For your information, Red Dot Award: Design Concept searches good designed inventions from around the globe every year.
Both air purifiers have the same tower design concept that debuted on the Levoit LV-H134 in 2020. It replaces the tradition of same shape from bottom to top which was well-known in the Honeywell HFD360B or Alen T500 devices.
While I can see from an engineering perspective the reason Winix has opted to make such a move (Winix never made any tower air purifier), a strong base and bigger body at the bottom to hold a relatively bigger air filter, and improve the performance of Winix NK105. That’s why I’m completely sold on the new look for variety of reasons.
The heights of both Winix NK105 and Winix NK100 are 29.5 inches, which are taller than common tower air purifiers, only smaller compared with the Levoit LV-H134. Build quality of the Winix NK105 is solid. Despite being tall, the air purifier has enough weight to stand firm on the ground, with 17 lbs in total.
The 360 Degree air intake, too, remains key selling point for the Winix NK105. Like the original Winix NK100, the Winix NK105 features air intake grills from both front and back of the air purifier. As before, this design language is a cut above the normal one-sided grill, making air flow system operate quicker and more powerful. The only tower device to offer better efficiency is the Levoit LV-H134.
On top of both these Winix NK105 and Winix NK100, there is an outlet air grill. The smaller shape grill is better at concentrating the air flow and moving the air consistently around your home.
Like I said earlier, the only way you can differentiate the two is the top control panel. The Winix NK100 includes a Child lock function button, while the Winix NK105 replaces this button for a new Wi-Fi connectivity button. In real-world use, the Child lock function prevents your children to accidentally press button and change the control. Meanwhile, a Wi-Fi connectivity button is necessary to help the Winix NK105 join the league of high-end machines.
There is a good handle in the back of both the Winix NK105 and Winix NK100, allowing you to move it around your home.

Winix NK105 Filters
When it comes to the internals of an air purifier, we must look for how many air filters and the air filter types are used. It looks like Winix is in love with the multiple-stage air filtration system, as in their marketing strategy, the smallest number is 3. In both Winix NK105 and NK100, we are having these 4-stage air cleaning system as below.
- Pre-filter – The polluted air must pass through a built-in pre-filter. This pre-filter will help capture the large objects of contaminants, such as pet hair and even some kinds of pet dander and skin.
- True HEPA filter – The True HEPA Filter that captures 99.97% of as small as 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
- Activated Carbon filter – The Coated deodorization carbon filter will eliminate kitchen and pet odors as well as smokes, also reduce the common household chemicals.
- Winix PlasmaWave – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.
Air filtration system is an area in which Winix has excelled in recent years. This is because of the combination of True HEPA filter with PlasmaWave Technology has far better efficiency than other common physical layer of filtration. In the Winix NK100 and Winix NK105 models, this company push the limitation as far as going all-in-one filter.
Many top-class brands are positioning their air purifiers with only one physical filter like that, for example Coway, and especially Blueair. You don’t need to know the difference between common air filter types, or which one to change.
Beside that, the Winix NK105 runs using the same PlasmaWave Technology. Although many people are now having high concern about the ionizers could irritate asthma issues, the PlasmaWave approaches in a different way. It creates positive and negative ions that combine with natural water vapor to form hydroxyls, which cleans the indoor air. All Winix air purifiers are tested and certified by the California Air Resources Board (CARB) to comply the standard safety level.
In my real-world test, the Winix NK105 has the same efficiency as the Sharp FP-F60UW (which has a similar technology named Plasmacluster) and Levoit LV-H133 in the same price range. Along with the Winix NK100, they all capture 99.93% any allergen particles as small as 0.3 microns. The $349 Alen BreatheSmart FLEX reduces the efficiency to only 96%, due to the use of HEPA-type filter.
My test conditions: All air purifiers run in the room of 200 square feet, for 1 hour.
Missing the AntiCel Treatment like in Winix WAC9500 doesn’t break the current performance of Winix NK105, as next to all low mid-range air purifiers I’ve tested, the Winix NK105 offers great performance. However, an all-in-one air filter N needs to be changed after one year, with a fairly higher cost of $119. The Levoit LV-H133 only costs you $84 for its air filter, and even the Alen BreatheSmart FLEX just keep it as high as $89.

Winix NK105 Room Coverage
One promise that Winix makes for their community is no ozone emission with the PlasmaWave Technology, therefore they need to reduce the voltage and fan power to fulfill the promise. As a result, both the Winix NK105 and Winix NK100 feature a 320 square feet room coverage. Though it is a little bit better than the Winix WAC9500, on an air purifier this size, it is still small.
The ACH of Winix NK105 is as high as 5X ACH. With high air changes per hour, this air purifier can clean your room as often as possible, once every 12 minutes.
The CADR of Winix NK105 is 221 Dust/ 207 Smoke/ 218 Pollen (cfm). The CADR rating of this Winix NK105 is a little bit lower than Levoit LV-H133, indicating that it will take more time to clean a room than the opponent from Levoit brand.

Winix NK105 Sound
With regular use I found the Winix NK105 is generally silent. Using the new advanced fan, the Winix NK105 can reduce the fan size while keeping the same performance. In this case, I tested a noise level of 33.7 decibels (db) at normal use. This noise level is far lower than the standard library noise level, and as you can see, is perfect for any quiet places.

Winix NK105 Power Consumption
One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.
Power consumption is not a strong field of Winix brand, but I’ve seen the serious improvement on both Winix NK105 and Winix NK100. Using a higher CADR rating fan power, these air purifiers have only 55 watts for the highest setting, which is better than the current 70 watts from Winix 5500-2 and Winix WAC9500.
With real-world use, for like 8 hours of using per day, it would cost you around $20 per year. Imagine that a dozen of eggs is $2, the annual cost to operate this Winix NK105 air purifier is lower than how you need to pay for eating eggs.

Winix NK105 Additional Features
Winix NK105 doesn’t just only offer the brilliant design and amazing performance, it also comes with tons of additional features. Sacrificing the Child lock function from the previous Winix NK100, the Winix NK105 adds a high-end feature instead – the Wi-Fi connectivity function. Now you can connect to your Winix Smart App (available on both Android and iOS), turn on your air purifier, and start to control it anywhere and anytime.
But that is not the only Smart feature you get in this device, as the Winix NK105 operates with an accurate Smart Sensor. An indicator light is showed on top of this Winix NK105, to tell you exactly the current air quality in your home. When the Winix NK105 senses the quality change, it automatically adjusts the speed at which it’s running to equalize the pollutants and create clean pure air. We called this function Auto Mode, meaning you never need to run your air purifier manually again.
Both these smart features are normally the signs of high-end air purifiers, and even the $349 Blueair Classic 205 doesn’t include both Smart features like Winix NK105. You need to pay for at least $600 Rabbit Air MinusA2 for both smart features and the same fan power as Winix NK105. So, when an air purifier ticks almost all of the boxes, why you need to pay more?
To answer this question, you still need to check the review of this aforementioned air purifier. However, Winix NK105 is still the next generation of today air purifiers, especially when you can get a discount deal for this device.
Thanks to the App Control, you don’t need an useless Timer on this Winix NK105. The LED indicator for filter replacement is much necessary, and of course the Winix NK105 will let you know when it’s time to change.
