Most other filters are recommended to be changed between 3 and 6 months, and possibly sooner if they are operational for most of the day every day.

What could be improved on?

The one improvement that can be made with the Levoit Core 300 air purifier is the addition of a remote so that users can change the settings or turn off the machine without getting up and pressing the buttons on the air purifier itself manually. However, there are no recommended improvements for the usability, efficiency, or effectiveness of this Levoit Core 300 air purifier.

Best Efficiency: Winix 5500-2 Air Purifier

The Winix 5500-2 air purifier is one of the most efficient on the market. In addition to the expected low/medium/high settings for the speed of the machine, the Winix purifier also has a turbo setting that reaches 240 CFM, which is double that of the normal high setting on air purifiers. This extra power enables the air purifier to clean the air in your room twice as fast as other standard air purifiers. Plasmawave technology guarantees clean, healthy air since it is a sort of permanent filter that breaks down odours, allergens, chemical vapors, and more. This technology, partnered with a true Hepa filter capable of capturing 99.97% of airborne pollutants, ensures that you only breathe in pure air after just a few minutes of operation.

The filter system is also equipped with an activated carbon filter for targeting even the most stubborn odours, and it is washable for long-term use and sustainability. A sleep mode allows the air purifier to continue running without a disturbance-causing noise level. The Winix air purifier is jam-packed with advanced technology and includes smart sensors that read the quality of your air and automatically adjust the fan speed to filter the air more efficiently when needed to maintain optimal levels of clean air in your home or office. It can handle a room size up to 360 square feet and operates between 28 and 70 decibels depending on the fan speed. If you prefer to set the fan speed yourself, a convenient remote allows you to make adjustments from a distance.

What sets the Winix 5500-2 Air Purifier apart?

There are a couple of features on the Winix 5500-2 air purifier that set it apart from others in its category. First of all, it is unique in terms of technology used. This air purifier uses Plasmawave technology and smart air quality sensors that achieve unheard-of levels of efficiency since it monitors the air and makes adjustments to clean the air more efficiently than manual models. Plus, an air indicator light visible at the front of the air purifier alert you to the quality of your air and the progress of the machine so you can feel confident that it is working and improving the health of your air. Plus, though a sleep mode is common for reduced noise while you sleep, the Winix air purifier actually switches back to auto mode all by itself when it senses more light in the room, so you don’t have to worry about remembering to change the setting in the mornings.

What could be improved on?

The only flaw with the Winix 5500-2 air purifier is that it does produce ozone because fo the Plasmawave technology. Though it is not produced in amounts deemed harmful to humans, those with sensitivities to ozone or with pets may want to turn off the Plasmawave technology to avoid dangerous symptoms. Beyond this, there are no flaws to note.

Filtration system

The Winix 5500-2 air purifier uses a 4-stage filtration system that weeds out all odours, allergens, pollutants, and chemicals from your air. It is one of the most effective filtration systems on the market with Plasmwave technology, a pre-filter for larger particles and pet hair, an activated carbon filter for odours, and a true Hepa filter for particles as small as 0.3 microns.

Floor area coverage

At 360 square feet of coverage, the Winix air purifier rests comfortably in the middle of the scale – it is the Goldilocks of air purifiers. It is efficient enough for medium-large rooms but is not an energy-waster like some of the 500+ square foot air purifiers.


The efficiency of the Winix air purifier is exceptional. A turbo fan speed enables the machine to cycle through the air in your room incredibly quickly, and it is Energy Star certified for greater energy efficiency compared to more basic models.

How to choose the right Air Purifier

Floor area coverage

The coverage area of an air purifier affects its ability to be effective in a space. Larger units can typically purify larger rooms, and smaller units are better suited for smaller rooms. Pretty intuitive, right? If you plan on moving the air purifier around the home to cleanse different areas, the floor area coverage won’t be quite as important. If it’s meant to stay in one central room, though, you’ll want to make sure the purifier is best suited for the space, so you don’t find it ineffective and a waste of your money.


It will be even more critical for large spaces that your machine is efficient because it simply has a lot of work to do. If you plan on leaving the air purifier constantly running all the time, its efficiency won’t matter quite as much since it has a lot of time to cleanse the air. However, if you intend on using the machine for only part of the day (only while sleeping or cooking perhaps), then you’ll need an air purifier that can handle a large volume of air in a short time. To do this, look for a high CADR rating. 

Filtration system

The filtration system in your air purifier is one of the most significant factors of its performance. Each filter type performs different functions and has its strengths and weaknesses. Often, different filter types will be included in the same machine to stack benefits. The filtration system in place will also determine the overall price of the machine, so you’ll want to look for your ideal balance between budget and features.

Noise level

Since an air purifier will likely be running more hours of the day than not, you don’t want to have the machine making a lot of noise, especially when you try to sleep or focus on work or your family. As time goes on, the technology in air purifiers continues to improve and allows for quieter operation. However, it is still good to look for lower fan speeds or different filter types for more silent machines. A sleep mode often offers lower noise for sleep or work as well.

Fan speeds

The diversity in fan speeds that an air purifier offers you will affect how quickly it can purify the surrounding air, how much energy it uses, and how loud it is. When everyone is trying to sleep, and there isn’t much activity sending contaminants into the air, a low speed is precisely what you want. On the other hand, if you are cooking an odorous dish or there is a lot of movement in and out of the house introducing a lot of pollution into your air, you’ll want the machine working at a higher setting. In general, more options are better to suit your changing needs.  


Air purifiers are not designed to clean an entire house from one spot, so you’ll need to be able to move the air purifier around to get an effective full-house cleanse. This is where portability comes into play. Ideally, you’ll want a lighter machine with wheels, so it is easy for you to move it from room to room whenever needed and even take it with you to a cottage or new living space if the need comes up.

HEPA Filters

HEPA air filters are the most common type of filter used in air purifiers. They are highly efficient at trapping all of the unwanted particles in the air, and you’ll find them with two different names. There are true HEPA filters and HEPA-type filters. True HEPA filters have a 99.97% efficiency rate, while HEPA-type filters have a 99% efficiency rate.

Filter life expectancy

Different types of filters will have different life spans, and the kind of air purifier they are in will also affect how quickly they degrade and become inefficient. Typically, a filter will degrade in 3-6 months, though others can last 8-12. However, if you have a high output machine working in a large space, the filter will likely need to be replaced more frequently.

Energy consumption

Since you’ll be paying hard-earned money for the energy an air purifier will be using to cleanse your home; you’ll want to look for a model with higher energy efficiency. This means a greater amount of clean air in your home without a crazy amount of energy being used. When it comes to a balance between the air purifier’s power and the thickness of your pocketbook, you want to lean as far towards energy efficiency as you can.


Do air purifiers remove odors too?

Air purifiers can remove odours as well as other contaminants, but they require an activated carbon filter. This is the only type of filter that can effectively eliminate odours as it traps the chemicals in the air that carry odour. Activated carbon filters are most commonly paired with HEPA filters. Since HEPA filters are the most common filter type in air purifiers, many models on the market do indeed remove odours.

How does an air purifier work?

An air purifier will draw air into the machine and pass it through a series of filters. Different types of filters provide additional benefits, so you will have to pay attention to the inner workings of an air purifier you’re considering. The filters will trap odours, pet dander, dust, smoke, pollen, and other allergens, depending on their composition. Once the air is clean of (nearly) all contaminants, it is sent back out into the room to circulate. Then the process repeats with new contaminated air. That’s it.

Do I need a HEPA filter or HEPA-type filter?

If you want reliably clean air, you should be on the lookout for a true HEPA filter. While HEPA-type filters use the same design, they are not nearly as efficient at trapping particles. True HEPA filters can trap particles as small as 0.3 microns. Since the entire purpose of an air purifier is to cleanse the air, a true HEPA filter is the way you want to go.

What is a CADR rating?

CADR stands for Clean Air Delivery Rate. The CADR rating is a measurement of how quickly an air purifier can remove the dust, pollen, and smoke particles. This can be in either cubic feet per minute (CFM) or in Canada, cubic metres per hour (m³/h). The larger the value, the faster an air purifier can clean the air quality.
