Winix C535 Air Purifier: Trusted Review & Specs

Winix has managed to create ripples in the American air purifier market with its sub-$200 air purifiers such as the Winix C535 and the duo Winix 5300-2 and Winix 5500-2. One would have thought that the low-range market would be the most active play field of Winix, and ignored any mid-range devices like the Winix QS or Winix HR1000. The fact that Winix is putting more effort into this segment with the series of low-range devices, continues to show the impact of this company on consumers with limited budgets. So far, we have done the Winix C535 Review to help you know whether to buy it or not.

Updated: The Winix C535 is now superseded by the next-gen Winix C545. The Winix C545 can be connected to a smart app for easy control. You should also look for the Winix 9800 and Winix C909, which have better performance.

Winix C535 ranks B in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:

winix c535 review

  • Solid built
  • Great performance with PlasmaWave technology
  • Low cost
  • 2-year warranty

  • High filter replacement cost

Together with the Winix 5500-2, the Winix C535 offers great bang for the buck with its impressive PlasmaWave technology. Both of these air purifiers consolidate the foothold of Winix in the low-range market, where the competition is the most aggressive, with names like Coway, Guardian Technologies and Honeywell. Now, let’s read the Winix C535 Review if you plan to go for a low-range device at the moment.

Winix C535 Price

The Winix C535 is an interesting model. In native Korean borders, it first comes up with a strange name “Winix AFS300-WC”. The purpose of this air purifier is mostly to replace the old 5300 model, but it is not the Winix 5300-2. The result, we call it the Winix C535 in the U.S market.

Winix decided to keep the price of the Winix C535 the same as the Winix 5300-2. The Winix C535 launched at $199, and will drop a lot if you follow our deal later.

With that price, the Winix C535 is left to fight it out price-wise against the ageing Honeywell HPA200, the newer AirGenius 4 and even the powerful Coway AP-1512HH.

It will also have to prove it has the means to overcome the Airmega 150, Levoit Core 400S and Airmega 200M, devices that have already established themselves at the base end. Oh, and let’s not forget about the new smart Levoit Vital 200S.

But if Winix wants to sell a device based on its unique PlasmaWave technology, a sleek and beautiful design from the previous 5300 Model, it would be the Winix C535. However, it’s hard to find a new Winix C535 at the moment, but if you love it, you can try to take advantage of our deal.

Winix C535 Design and Size

The design of the Winix C535 isn’t as impressive as it is on the Winix 5300-2, and I truly don’t understand the reason why. Perhaps the white color is something that’s unfamiliar with the previous 5300 users.

All of that said, it’s still the same structure as both the Winix 5300-2 and Winix 5500-2 thereafter. This air purifier has a plastic body and stands on a small but solid base. It is enough for the 23.6-inch air purifier to be firmly put anywhere in your home without weirdness.

For the airflow system, you still have a normal bottom-to-top concept, with a huge front air intake grill. If you are familiar with air purifiers with front air intake, you will be surprise because there are 2000 holes on the front panel of the Winix C535. However, from the engineer’s perspective, I don’t find these holes to make any sense.

On top of the Winix C535, we will have the traditional control panel, as well as the air outlet grill. The control panel leans to the front, making it difficult to press the buttons properly. Personally, I would prefer a classic top control panel, which I could easily bend to reach the buttons.

Below is the LED light indicator, which indicates the current indoor air quality.

The Winix C535 is only 15.4 lbs, and with two handles on both sides, you can move this air purifier easily. Also, because of the small base, the Winix C535 must be put on hard and flat surfaces to work properly.

Winix C535 Filters

Winix C535 is an old and budget model of this brand, and we can’t expect to see the latest air filtration process in this device. To decide the performance of an air purifier, we should look for how many air filters and the air filter types are used. For that, the Winix C535 is using a 3-stage air cleaning system as below.

  1. 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. The pre-filter is also attached to an Activated Carbon filter to help reduce the pet odors and smoke, as well as some common household chemicals.
  2. 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.
  3. Winix PlasmaWave – This technology is one kind of ionizer, which can further reduce the amount of pollutants. Can be switched on/off.

We all know that nearly every Winix air purifier released will have the PlasmaWave feature, which is also the unique selling point of this brand. The Winix C535 is no different, and the combination of both True HEPA filter and PlasmaWave Technology is pretty on top of general air filtration in the low-range.

Talking a bit about the PlasmaWave Technology, this is one kind of ionizer. However, the normal ionizer will emit only negative ions to charge the pollutants back to something like a collector plate. The PlasmaWave, however, emits both negative and positive ions, to form hydroxyls that attack airborne pollutants such as viruses, bacteria, germs, odors, and chemical gases (VOCs).

With double the certified protection, the Winix C535 can score an amazing efficiency. Put it in a test with the Honeywell 50250 and the Honeywell AirGenius 4, we can see how great our today air purifier is. Both the Honeywell 50250-S and Winix C535 had the efficiency of 99.93% for trapping any airborne particles down to 0.3 microns, while the AirGenius 4 dropped to only 92%.

Again, we will have to cry for the air filter cost of a Winix air purifier. With the Winix C535, you need to pay for $69 each year. This price is at least $20 higher than the average of other air purifiers in the low-range.

Winix C535 Room Coverage

Aside from the innovative air filtration process, the fan power of this Winix C535 is decent for the price. The room coverage of this air purifier is 360 square feet, which is nearly the same with Honeywell 50250 and GermGuardian AC5900W.

The ACH of Winix C535 is 4X. I believe that this air changes per hour rating is good, because you will receive the fresh air once every 15 minutes.

The CADR of Winix C535 is 243 Dust/ 232 Smoke/ 246 Pollen (cfm). With the higher CADR rating than most of other Winix devices. Honestly, you will enjoy the fresh air as soon as you turn on the device.

Winix C535 Sound

I’d consider myself one who find it difficult to sleep, and love a device that can run with little to no sound. Sadly, the more powerful an air purifier is, the louder it become.

However, in the case of the Winix C535, the noise level is only 28 decibels (dB), which is lower than even the whisper. Of course, when you run the air purifier on Turbo setting, you will hear the sound, but it is just one kind of white noise and won’t distract you.

Winix C535 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.

In day to day use I found the power consumption of this Winix C535 is about 70 watts. I am not surprise with this result, as the Winix air purifiers have history of consuming more energy than other brands in the same price range. For a better power saving air purifier, you should look for the Levoit LV-PUR131 or the Coway AP-1512HH.

For using Winix C535 8 hours per day, it would cost you about $25 per year.

Winix C535 Additional Features

In the world of low-range air purifiers, the brands are competing against others mostly with some flashy additional features. Winix is such brand. With most of its devices are under the low-range, clearly Winix needs something to win the loyal of the customers.

First is the necessary Smart Sensor, a more and more popular feature which is a must-have in high-end air purifiers. With this sensor, the Winix C535 can tell you exactly the current indoor air quality, using the LED indicator on the front of this air purifier. But the Smart Sensor is not only for reporting, it also triggers the Auto Mode to adjust the fan speed automatically to clean the air better. With this mode, you can just turn on the air purifier, and then totally forget about it.

However, one downside is that the dust sensor of the Winix C535 needs to be cleaned regularly. I have read many reviews of it stop functioning properly after a while, and I will update this review as soon as I find any problems.

If you are fond of the Wi-Fi Enabled Connectivity feature, you should look for the Winix C545 and Winix AM90 instead, as they both offer this high-end feature while keeping the price nearly the same as the Winix C535.

As usual, the Winix C535 has a LED indicator for filter replacement and a basic Timer to control the device. This air purifier also comes with a remote control so you can stay in one place and still have full control over your air purifier.

Winix C535 and Winix 5500-2 are the most popular air purifiers from this brand. Despite lacking some key features with the new Winix air purifiers, the Winix C535 is a successful device from this Korean brand, especially when it has lots of convenient smart features, as well as a great perfection in air filtration process.
