I chose this particular air purifier since it has an impressive 4-stage filtration system, can cover a room up to 360 square feet, and comes with a moderate price tag.
What attracted me the most was the PlasmaWave technology that seems to battle mold, bacteria, viruses and other harmful particles without creating any ozone emissions.
After reading through various reviews and speaking to the owners of such air purifiers, I came up with an extensive evaluation that can, hopefully, help you decide if this unit is suitable for your needs.
I’m always looking for a budget air purifier that can deal with a variety of air contamination problems an average homeowner might face. That’s why the filtration system is the first thing I pay attention to. This particular model seems to have a formidable 4-stage filtration option.
- Permanent Pre-filter –deals with such large particles as hair, dust, and some pet dander. This filter doesn’t need to be replaced but has to be cleaned with a vacuum cleaner or a soft brush once about every two weeks. Cleaning this filter on a regular basis can extend the life of other filters.
- Activated Carbon filter – This filter does a good job eliminating the odors that appear in stuffy rooms, kitchens, and places where people smoke. The main feature that makes this filter different from some of the others is the CleanCel coat. It doesn’t allow the mold and bacteria to grow inside the air purifier. This is a great advantage since it keeps the filter functioning longer and doesn’t let the harmful particles to be released back into the air. The carbon filters need to be replaced once every 3 – 6 months. The carbon filter that comes with this air purifier gets great reviews. It helps eliminate the odors even in the room with heavy smokers.
- TrueHEPA filter – This filter captures 99.97% of all the harmful particles, such as dust mites, pet dander, pollen, and mold spores. The trueHEPA filter is designed to keep the air as clean as possible. Depending on the frequency of the air purifier use, you’ll need to change the HEPA filter about once every 12 months. You can purchase the yearly replacement filter package (4 pre-filters and 1 HEPA filter) for around $40
- PlasmaWave Technology filter – This technology made me take a closer look at this air purifier. Essentially, this is an ionizer. However, the manufacturer claims that it does a terrific job dealing with all types of viruses, bacteria, chemical vapors, and even smells. The positive and negative ions produced by the air purifier create plasma clusters that eliminate all the above problems. This technology is permanent and doesn’t require any replacement filters or other maintenance. This feature can be turned off and on whenever you wish.
The filtration system seems to do an adequate job of cleaning the air. The only downside I see here is that the carbon filter needs to be replaced every 3 months. While it can seem like a financial disadvantage, it’s actually a good thing for the air quality of your room. No matter how efficient the filters are, the more often you replace them, the better job they do.
When it comes to the design of this unit, I can say that I really like it. This air purifier is not too large and weighs about 17 pounds, which makes it easy to move around the house and can also go down to the basement when needed.
The unit comes in white and black colors. While I prefer the black option, the white one is also good for some decors.
This is a floor-standing model. It’s not too high, so if you are not a fan of flaunting the air purifiers, you can stick this one behind a sofa or an armchair. However, the manufacturer doesn’t recommend placing this purifier close to the wall. In order for the air circulation to be ideal, you need to install it at least 15 inches away from the wall.
I also liked the operation panel on top of the unit. It’s nicely designed and pretty straightforward. While I would still recommend reading the manual before using this air purifier, the pictures on the control panel speak for themselves.
For a moderately priced model, this air purifier is equipped with an impressive number of sensors.
- Sleep mode – When the lights go off, the unit automatically adjusts the fan to the quietest setting and dims the control panel lights. This is a wonderful option for people with sleep problems who can’t fall asleep if the room is not completely dark.
- Air Quality Sensor – When you set the auto mode, you don’t have to worry about the air quality reduction. As soon as the sensor determines that the air quality is low, it automatically adjusts the speed of the fan to improve the clean air circulation. The auto mode is optional. You can adjust the fan speed manually if you wish. You can also follow the air quality by checking out the air quality indicator. You can literally see the air in your room becoming cleaner.
- Filter Replacement indicator – This air purifier is equipped with a filter replacement indicator. However, it only works for the trueHEPA filter. You need to remember to replace the carbon filter on your own. In any case, this is a good feature since there is one less thing to worry about.
Since I’m a light sleeper, I always pay the closest attention to the noise levels air purifiers produce.
This air purifier comes with a fan that has four speeds. Obviously, the lowest speed is the quietest one, and so on. I’ve read through many reviews in order to determine what light sleepers like me had to say about the noise levels. The manufacturer claims them to be 55 dB at the highest fan setting. This is pretty low. 55 dB is not louder than a quiet conversation.
After doing some research, I found that most of the air purifier owners are happy with the noise levels it produces. It came as a surprise to me since there are always at least a couple of people who say that the air purifier is noisy. In this case, I can happily say that the manufacturer is telling the truth. This unit is truly quiet. Of course, when it’s set at the highest level, it might interfere with your sleep. Meanwhile, the other three fan settings are satisfactory even for the bedroom use. You can use the 4th setting when you are awake and it won’t interfere with watching TV or reading.
One noise problem that the users can face when operating this air purifier is when the PlasmaWave option is enabled. The unit can produce buzzing sounds when the particles are eliminated by the ionizer. Since this feature is optional, I wouldn’t recommend turning it on during the night.
I’d like to commend the manufacturer for creating an energy-efficient unit. Considering the moderate price, the energy efficiency of the air purifier comes as a nice bonus to all the above advantages. Below is the energy consumption rate:
- Speed 1 – 14 watts
- Speed 2 – 34 watts
- Speed 3 – 70 watts
- Speed 4 – 128 watts
This means you can save money on your monthly energy bills even if you have to use the air purifier around the clock.
The manufacturer claims that this air purifier can service a room up to 360 square feet. The CADR rating of this unit is:
- Smoke – 232
- Dust – 243
- Pollen – 246
If we use the simple formula (CADR x 1.5) to calculate the coverage area, we get 350 – 360 square feet, which means the manufacturer offers us the correct information. 360 square feet is a fairly large space so you can safely use this air purifier in most of the rooms in your house, including the basement and the attic.

I believe that long warranty is the indication of quality. The longer the warranty is, the more the manufacturer is certain that the item can hold up for a long period of time. This model comes with a 2-year warranty, which is a great advantage.
The warranty is valid only if the air purifier is operated according to the manual and the filters are replaced on time. You can only take advantage of the warranty in the USA and Canada.

Winix 5300-2 Air Purifier review conclusion
After doing extensive research and reading the reviews, I’m ready to recommend this product to people, who are on a tight budget. Truth be told, I don’t think I’ve reviewed such a moderately priced product with so many impressive options before. The only significant downside I see here is the yearly filter replacement that costs about $40. Other than that, this unit is a wonderful choice for rooms under 360 square feet.
