Winix C535 Review

Winix has been making waves in the air purifier market for a while now, and the company has created a range of affordable models. While these air purifiers are designed to be very effective and stylish, they will not break the bank. Some of the models in the collection include the Winix 5300-2, the Winix HR1000, and the Winix QS.

However, the Winix C535 remains one of the company’s most popular air purifiers to date. In fact, this is one of the bestselling air purifiers in the USA in its category. So, let’s check out this Winix C535 review to find out what makes this model so special.

Our rating:4.5 out of 5 stars (4.5 / 5)

Winix C535 Overview

Design and Size

In terms of design, this model is compact and aesthetically pleasing. It comes with a small and solid base. At just 23.6 inches, this model is likely to fit into any room with ease.

The Winix C535 weighs just 15.4 pounds, which helps to make it especially portable. This is also aided by the fact that there are handles on either side of the machine. Once the air has been purified in one room, users can then move this model to another room if they wish.

The Winix C535 features a traditional control panel that leans to the front slightly. Unfortunately, this makes the buttons slightly difficult to press. This may be a little frustrating at first, although most users are likely to adapt to it.

Operational Noise

Unlike many other competing models, this air purifier is virtually silent. This means that it can be installed in a bedroom if desired without disturbing your sleep. Even babies will be able to sleep soundly, and the soft hum of this model may even help them to sleep.

The Air Flow System

The usual bottom-to-top concept facilitates the air flow system of the Winix C535. It comes complete with a front air intake grill that is especially large. However, unlike many other models of this type, the front panel comes with two thousand holes.

The Air Filters

It should be noted that the air filter has to be changed regularly for the best performance. Fortunately, this is very easy to do. The main drawback is that the air filters tend to be much more expensive than those of other models.

However, for people who live with pets or smokers, this model is likely to save the day. It has a solid reputation for working very quickly and efficiently. In order to clean the air efficiently, the C535 uses a three-stage air filtration system.

This model comes with a built-in pre-filter that draws in the polluted air from the surrounding environment. This helps to capture large contaminant particles like pet hair, dander, and skin.

The pre-filter is attached to Activated Carbon filters that are designed to reduce odors from tobacco smoke. These special filters also help to reduce other types of unpleasant odors. People who live with pets are likely to find that this filter works wonders at freshening the air.

The final filter is the True HEPA filter. This mighty filter is designed to capture 99.97% of particles, including those as small as 0.3 microns. This helps to ensure that virus particles, pollen, mold, and even fungi particles will be captured from the air.

Air Quality

Users of this model can enjoy pure peace of mind that the air quality in their room is constantly being improved. The current indoor air quality will be indicated by an LED light below the control panel. When the model is switched on, users will literally be able to see the air quality improving.

Cutting Edge Technology

The Winix PlasmaWave is a special type of ionizer that can further reduce the number of pollutants in the air.

The almost unique combination of a True HEPA filter and the patented PlasmaWave Technology helps to put this model at the top of its class. The PlasmaWave emits both negative and positive ions in order to form powerful hydroxyls. These then attack airborne pollutants like viruses, bacteria, germs, odors, and chemical gases.

In effect, users are treated to double the protection that they can expect from most competing models in this class. With an efficiency of 99.9%, the Winix C535 manages to out-perform virtually every other model.

Room Coverage

This model is designed to clean the air in rooms that measure up to 360 square feet. The ACH of the Winix C535 is 4X, meaning that users receive fresh air every fifteen minutes. Users are treated to fresh air straight away, and it is constantly being refreshed.

Plenty of Power

One of the downsides with powerful air purifiers is that they tend to drive up electricity bills significantly. The power consumption of this model is typically around 70 Watts. This is fairly average for a unit of this size and is quite reasonable considering how quickly it cleans the air.

Extra Features

In order to attract attention from potential buyers, many manufacturers tend to pack in plenty of features. Winix is no exception, and this air purifier includes plenty of bells and whistles. These include a Smart Sensor, the LED indicator, Auto Mode, and a timer.

The Smart Sensor is quickly becoming a very popular feature that is used in high-end air purifiers. With this sensor, the Winix C535 is able to precisely calculate the current indoor air quality.

In addition to reporting, the Smart Sensor also triggers the Auto Mode to automatically adjust the fan speed automatically to clean the air. This mode allows users to simply turn on the air purifier and completely forget about it. However, users should note that the dust sensor has to be cleaned regularly in order to remain effective.

The Winix C535 comes with an LED indicator for filter replacement as well as a basic Timer to control the device. This air purifier comes complete with a remote control. This allows users to stay in one place while enjoying full control of their air purifier.
