Air purifiers have become a necessity in today's day and age, and we can understand it. The pollution levels are rising every day, and it can bad for people living in populated areas and cities. When you purchase the right purifier, it can make your life easy and healthy, but if you choose something that's not right, then it can create problems in the long run. Selecting an air purifier can be a hectic task for anyone, when we first looked up for air purifiers a few years back, we used to confused just like most of the people. But after using and operating some of the best air purifiers, we got to learn a lot about the technologies used and what's right and what not for a user. We have reviewed some of the best purifiers and today we are going to look at the Winix C535. When it comes to Winix, they have done a great job in manufacturing some of the best air purifiers in the mid-range segment.

Winix C535 is just another example of feature-packed air purifier in the mid-range segment. We were excited to review it as we have already used Winix 5000-02 by the company. The expectations were quite high, and it was able to live upto the hype. We knew that being a mid-range air purifier, it will not have high-class features. But still, the company has used different technologies to make it worth the price. It is one of the best affordable air purifiers that we have come across. In this review, we will be looking at the features, working, and functionality of the machine. We were quite excited to get our hands on the device. So, let us now dive deep into the review.

The package of the Winix C535 was beautiful, just like the design of the machine. The company tried to highlight the best features on the outside cover of the box. We were delighted to open the packaging and look at things that we get inside. The package arrived at us in good condition, and there were not wear and tear signs on the box, which is usually found in the box shipped by the companies.

When we opened the box, we found the air purifier, a remote control, and instruction manual. The instruction booklet has a lot of information that we would recommend you to read before you start using the machine. The air purifier arrives in assembled form, so there's no need to worry about it. We were delighted after seeing the way everything was kept inside the box. The company has done a lot of hard work in manufacturing the machine.

Design: When you look at the Winix C535, it doesn't have an impressive design that will you go wow because the company has manufactured better design models. Though, the white color might entice some of the users. It has a similar structure to Winix 5300-2 and Winix 5500-2. The air purifier has a plastic body, and it comes with a stable and robust base. The base may look small, but for the 23.6-inch air purifier, it is sufficient. The machine is slimmer and can be carried easily around the house. It weighs in at around 19.4 pounds. The dimensions of the purifier are also not that big, which means it can easily fit in any room.

Talking about the airflow system, it follows the standard procedure just like other air purifiers. There is the presence of a large air intake grill on the front side. If we go by precision, then there are almost 2000 holes in the front panel. However, this doesn't make a lot of difference.

Just like Winix 5500-02, we find the operating panel on the top and also the air outlet grill. The control panel is similar to what it used to be an old washing machine. It makes pressing the button of the device quite tough. It also has a LED indicator on the bottom that tells about the air quality in the room. For portability, the machine comes with two handles on the side as there is no presence of caster wheels at the bottom. We would suggest you take help from someone if you face any difficulties while moving the machine. When we look at the overall design, it is not impressive, but it is not bad either. It will easily fit into your home or office decor.

We have always appreciated the way the Korean giant uses different technologies to make an affordable product. They were able to achieve something similar in the case of Winix C535. We would say that looking at the filtration process was the best part of this review. And, that's something that we focused on a lot. Just like, Winix 5500-02, we get a three-stage air filtration process:

- Pre-Filter: The polluted air must pass through the pre-filter. It helps in cleaning the bigger dust particles, contaminants, such as pet hair and even pet dander and skin. The company has also attached an Active Carbon Filter to help reduce and trap pet odors and smoke and even some household chemicals.

- True HEPA Filter: The company has provided the user with True HEPA Filter that captures 99.97% of as small as 0.3 microns virus particles, pollen, allergens, mold, and fungi particles.

- Winix PlasmaWave: The company has provided with the similar technology that was found in the Winix 5500-02. PlasmaWave technology is nothing but a type of ionizer, which is used for trapping and reducing pollutants. It can be turned off or on by the user according to their needs.
If you love the Winix machine, then we are sure that the power of this purifier will amaze you. It also utilizes the PlasmaWave Technology with True HEPA Filter. The PlasmaWave is a technology that forms Hydroxyl Radicals to attack and reduce the air pollutants and some household chemical gases. The destroyed pollutants and bacterias come out in the form of vapor.
The only problem that I found with the purifier doesn't have a proper ionizer. Though, the positive is that the PlasmaWave technology performs the same work, and it doesn't emit harmful chemicals. It also helps people who are suffering from respiratory diseases.

If you are one of the curious minds who want to learn about the working of the machine, then we have mentioned it here.
The air purifier first inhales the air in the atmosphere through the front panel and then cleans the air using a layer of activated carbon, a true HEPA filter, and lastly, Winix's PlasmaWave filter. The polluted air gets filtered by the pre-filter and the attached activated carbon layer, which helps in reducing the large particles and also pet odors. After passing through the first layer, the air comes to the HEPA Filter. It is the most vital layer in the filtration process because it is where most of the filtration takes place. The US Department of Energy has certified the air purifier for having the capability to catch 99.97% of particles larger than .3 microns. Lastly, the air is sent to the PlasmaWave layer where it is treated with Hydroxyls to remove any VOCs, bacteria, and viruses.

Room Coverage: One of the most critical aspects that you need to check before purchasing an air purifier is the room coverage capacity. When it comes to Winix C535, its room coverage capacity is 360 square feet, which is similar to Winix 5500-02. We were extremely pleased with it because the area the company promises gets cleaned easily. Again, the ACH of the machine is identical to that of 5500-02, and that's 4X. The rating is decent as it can clean the room every 15 minutes, and you will always get fresh air. When it comes to CADR of the purifier, it is 243 Dust/ 232 Smoke/ 246 Pollen (CFM). It is a higher rating than what is found in most of the Winix machines.

Sound: Another vital factor that you need to look up is the noise that the purifier makes while running at lowest and highest settings. The noise level is also similar to that of Winix 5500-02 when we tested it. We found that when you use the machine at its lowest setting, the noise level is around 30 decibels, whereas when you operate it at Turbo setting, it nearly doubles. Yes, we were not impressed by it, and we think that a lot of better effort could've been made by the company so that users don't get irritated by the sound.

Final thoughts on Winix C535 True HEPA Air Cleaner with PlasmaWave Technology:

When we looked at the air purifier for the first time, we were not massively impressed by its design. But, after looking at the features, we can say that it is one of the most affordable air purifiers that you can purchase. Everything from the air filtration process to durability, the company has done an excellent job. We were pleased to see that the filtration process is similar to that of Winix 5500-02 except for the presence of Advanced Carbon Filter, which would've added to the cost of the purifier. Despite being a low budget machine, we are happy with all the functions.

Another thing that could irritate some users is the operating panel because the buttons are stiff due to the inclination on the front side. You can quickly check the quality of air inside the room with the help of LED indicator present on the front side of the machine. It is portable and can be quickly transferred from one place to another with the help of two hooks on the side. The device weighs just around 19.4 pounds, and the dimensions are also not huge, which means you can easily store it inside any room of your house. The company recommends the users to keep the purifier on a flat surface to get maximum benefits and use it without any issue. Overall, we were delighted with the functioning, and we would love to recommend it to you. Before thinking of a purchase, read all the necessary information mentioned in this review carefully to save yourself from any hassle in the future. We would be coming up with more product reviews for you. Till then, keep shopping.
