Also, with such a broad span of reach, it would be tiresome to keep walking to the device to change settings; hence the inclusion of a remote. This makes it more convenient to change settings from low to high when the quantity of contaminants has increased or decreased.

At some point, the integrity of the filters is going to be compromised by the particles that are already trapped. When this happens, the tool won’t be as useful in clearing the air as it once was.

The first stage is the ultimate pet filter, and this is especially useful where you have multiple furry animals living in the house. You then get a washable pre-filter, which means you can take it out and clean it before replacing it if the contaminants are preventing the device from working at full potential. Another thing you could write home about with regards to the invention is the advanced odor control. The result of using this device will consequently be fresh smelling air all around.

Anything that gets past the above two filters will get stopped by the HEPA and other filters as the air is pushed out of the device.

  • Room size: 360 sq. Ft.
  • CADR (Dust / Pollen / Smoke): 243 / 246 / 232

Other features: 3-stage filtration, VOC Sensor, air quality indicator, filter replacement, automatically adjusting fan speed, Energy Star and ARB certified, AHAM Verifide, 27.8 dB

The Winix 5300-2 is quite similar to the Winix 5500-2 in a lot of ways. The first is the auto-mode that will adjust fan speeds according to the air pollutant levels and all without needing your input. Area coverage is as well-rated at 360 sq.ft. meaning it can cover just about the same area as the editor’s choice. Where the filtration system is concerned, the unit combines a PlasmaWave, HEPA filter, and Carbon filter to give the best results. This will allow the tool to clear out pet dander, mold, cigarette smoke, dust, and any other elements harmful to your overall wellbeing.

You can choose manual mode where you have full control over the fan speeds the device exhibits at a particular time. These include low, medium, high, and turbo. The latter two are for when contaminants seem to be in high concentration. When you use these two, you get high power, but there may also be some noise output following the device operation.

You can own the device for close to 120 dollars. However, filters are going to cost you a pretty penny over time, as they need to be replaced regularly. This device may be cheaper than the 5500-2, but it also loses a prominent characteristic included in the editor’s choice, namely the option of remote control. As such, users may have to sometimes walk across the room so they can change settings on the buttons positioned on the device.

  • Certified by multiple bodies

  • Filtration: pre-filter, carbon filter, HEPA, PlasmaWave

  • Warranty: 2 year
  • Wattage: 55 W

The shape of this device is unique in our line-up, with the other options predominantly having a rectangular silhouette. The area that this device can cover with its air-purifying prowess is a bit smaller than that provided by the Winix 5300-2 and the Winix 5500-2. However, some people might consider this difference negligible.

Performance-wise where cleaning air is concerned, this invention performs up there with the best of them. This is because it incorporates four types of filters into one cylindrical one. This is inclusive of the HEPA filter in addition to the carbon filter and PlasmaWave. There is also the inclusion of a pre-filter to eliminate some of the bigger particles in the air.

As well an LED indicator light is included on top of the device that incorporates readings from the sensor to change colors and indicate the condition of air quality around you. If the light turns blue, you can breathe easy. On the other hand, is the light is a red color, you need to set the fan to turbo since there is a lot of cleaning to be done. The auto mode reacts to the reading of air quality to turn the speed of the fan up or down.

Also, while the LED light may be bright enough to be seen during the day, the manufacturer knows that the same amount of light at night may be too much. Consequently, they have included an ambient light sensor that also works as a regulatory tool for the light produced by the LED. As such, you will see the light dim a little during night time.

  • Ambient light sensor
  • 4-in-1 filter
  • LED filter replacement indicator
  • Auto-mode
  • Replacement filters are known to be pricey
  • No remote control

Features to consider when choosing a Winix air purifier

As with all other gadgets, the features will differentiate the best products from other riffraff in the market. Consequently, you can see the features list highlighted below as you check to see what it means for a Winix device to possess specific characteristics.


People like pieces of equipment that can do their job well without being too conspicuous. As such, the dimensions matter a lot where they give an idea of the overall size of the device.

Big devices will generally tend to pack more features in them as they possess more space for additional components.


Type of filtration

The type of filtration incorporated by the device is also a worthy area to look into. If you look into the Winix NK100, you will notice a four-stage filtration system, which is one more advanced than other systems on the list. It includes a HEPA filter, PlasmaWave filter for odors, carbon filter, and a pre-filter, so the rest of the filters don’t have to work so hard at cleaning the air. Other devices like the Winix HR900 also feature a pet filter that makes it worth the extra money if you have dogs, cats, or different types of furry pets in the house.

Room size

5 Best Winix Air Purifiers to Improve the Air Quality in Your Office and Home

If you look at the Winix P450, its coverage spans 450 sq.ft. On the other hand, the area coverage by the Winix HR900 is only 300 sq. ft. If you have some rather large rooms in your house, you are probably going to buy the former since it allows you to clean the air in such rooms with a single purchase. If you choose the HR900, you may have to purchase more gadgets to get the same air cleaning effect. Smaller rooms, however, will allow you to buy devices without as much area coverage and still be comfortable.


Multiple bodies line up to certify Winix devices since the company has proven to be a producer of quality tools. Energy star certification, for instance, tells you the device is quite efficient in the use of power. AHAM Verifide will, on the other hand, notify you of the device’s proficiency in removing contaminants from the air around you. Each certification is unique and will allow you to gauge how well a device performs in a particular area.


The rules here are simple. The more extended the warranty, the better. Also, the terms of the warranty may be different as to the type of compensation you get when you claim the guarantee. Reading through each devices’ warranty terms is, therefore, a requirement before making a purchase.


Most devices by the same manufacturer perform noiselessly while the first three fan speeds are activated. The turbo, however, seems to be quite loud. You can check noise ratings to see if you are capable of handling the device.


You may also want to know the power consumption rating of the Winix Air purifier you end up buying. If you are looking to conserve energy, some of the devices on the list above may not be ideal. Nevertheless, you can get the Winix NK100 with the least power consumption needs of any device featured.


When you use PlasmaWave technology, the filter will generate positive and negative ions. The purpose of these ions is to break any pollutants in the air such as smoke at a molecular level, and this serves to clean indoor air without creating a harmful ozone.

If you suffer from allergies, always make sure that your purifier has a HEPA filter in it. These filters serve to remove allergens that are 0.3 microns in size and bigger. Coincidentally all the devices featured above also contain such a filter.

Our Verdict

If you own pets, you will love the Winix HR900, especially if you have multiple furry friends. You want to still breathe quality air without the presence of pet hair and dander, and this device is guaranteed to help you do that. That is why it would feature in our top three picks.

Another draft that would make the ideal purchase is the Winix P450. Big rooms may require you to purchase two or more purifiers. Nevertheless, with these devices’ area coverage, you can get by with buying one.  If you want an all-round quality tool where purification and coverage are concerned, the Winix 5500-2 is a great pick. Make a wise and informed choice as you pick from the options we have provided above. Don’t forget that commenting below and sharing your experience with the tool may also help other users find the Winix air purifier they have been looking for.
