The Winix Air Purifier Range Explained

When it comes to protecting your family’s health, you want to have a lot of options to choose from. Winix offers a full range of high-quality air purifiers that can filter the air in small, medium, or large rooms.

What makes Winix air purifiers so popular is its PlasmaWave technology. This technology filters air by naturally creating positive and negative ions that safely irradicate pollutants by breaking them down at a molecular level. This breakdown occurs without the production of ozone.

Why Choose Winix Air Purifier Brand?

Filtration Technology

Winix features 3, 4, and 5 stage systems. Each stage features a pre-filter, carbon, or HEPA filter that purifies the air. The number of filters in your WInix machine is determined by the number of stages.

Every model contains a pre-filter that is washable. Every model also includes a form of a deodorizing carbon filter. Each machine comes with a HEPA filter that eliminates allergens. The type and efficiency vary depending on the machine.

Winix 4 Stage Cleaning System

PlasmaWave Technology

This technology is revolutionary in air purifiers today. It can irradicate pollutants at a molecular level by breaking them down into nonharmful substances such as hydroxyl and water.

The electrical charge that emits these polarizing ions is harmless and happens in nanoseconds. Since the ions naturally attach to bacteria and remove the hydrogen atoms, the air that is produced is free of ozone.

Smart Sensor

Winix equips their machines with an indicator that alerts you when it is time to change the HEPA filter. The machine detects levels of build-up within the filter to identify if it is working efficiently. If it is not, then the indicator will glow red.

Air Quality Indicator

The Winix devices on our list are equipped with multiple sensors to help you understand the quality of your air. Winix includes an air quality indicator, a dust sensor, an odor sensor, and a light sensor.

The air quality indicator will tell you how polluted the air is. The dust sensor will alert you to large amounts of dust. The odor sensor will indicate unpleasant smells in the environment.

The light sensor will detect when it is dark in a room and turn on the noise reduction system.

Odor Control and Allergen Removal

Winix products control the odor in an environment by the high-efficiency carbon filter. Carbon naturally filters out odors, so, at this stage in the filtration process, odors will be removed.

Allergens are eliminated primarily by the use of a true HEPA filter. The microns of allergy pollutants are filtered by the hospital-quality HEPA filtration system.

Energy and Cost Savings

Some household appliances are more expensive to run than others. An air purifier is on the low end of that spectrum. Winix air purifiers cost significantly less than a refrigerator or air conditioner to run on a monthly basis. The average cost per month is around $3 to $8, depending on location and hours of use.

Extra Features

Some of the Winix range comes with a few extra features that might interest some homeowners. Some models include WiFi connectivity so that you can control the air purifier from your phone.

Other models come with Bluetooth to connect to nearby devices. One Winix model even comes with a set of built-in Bluetooth speakers.

Multi-year Warranty and Customer Support

All of the Winix models that we will review below come with a 2-year warranty. This warranty ensures that the machine is free of any manufacturer’s defects or other problems.

The customer service from Winix seems to be average, according to consumers. They will generally fill warranty claims quickly as long as your product is registered and they can offer assistance.

7 Best Winix Air Purifiers Reviewed

1. Winix HR900

Our Top Pick
Coverage Area300 Sq ft
Filtration Type5 stages
Filtration Life1 year
Noise Level26 – 52 dB
Air Quality SensorYes

If you have a pet and want the best possible solution to filter out allergens and other pet dander, then this model may be the best option for you. We chose the Winix HR900 as our top pick in the Winix range.

This Winix model comes with a 5-stage filtration system that starts with the Winix Ultimate Pet Filter. The next stage is a pet hair specific pre-filter that can be washed. It has an Advanced Odor Control (AOC) carbon filter that is also washable.

The true HEPA filter can remove particles as small as 0.3 microns. The final stage is the patented PlasmaWave technology that eliminates the remaining allergens and bacteria.

This model comes with an air quality sensor that will sense odor and dust particles and change color depending on the quality of the air. There are three different colors to quickly notify you of the quality of your air.

We liked that this model was ideal for people with pets. It helps eliminate pet hair, dander, and odor. We thought that it was a little bit small for some homeowners since it’s only sufficient for rooms that are up to 300 square feet.

We also thought that the pet pre-filter tended to get dirty very quickly, which means it’s doing its job, but it needs to be washed often.

Pros

  • Ideal for homeowners with pets
  • 5-stage filtration system
  • Only one of the filters needs replacing; the other three are washable

Cons

  • May not be suitable for very large rooms

2. Winix 5500-2

This Winix model comes with a 3-stage filtration system. It starts with an Advanced Odor Control (AOC) carbon filter that eliminates odor and other pollutants.

We thought that this model was ideal for families that have medium-sized rooms. Since it has a remote control, it is also good for people who want a set it and forget it type of machine. One downside is that it only has a 3-stage filtration system. It may not purify the air as well as a 4 or 5-stage system. 

One user noted, “I love this air cleaner. I call it the odor detector. It keeps the rooms clean. The air smells clean.”

Pros

  • Includes a remote control
  • Ideal for medium-sized rooms

This Winix model comes with a 4-stage filtration system, which falls between the two that we previously reviewed. It comes with the fine mesh filter, odor-reducing carbon filter sheets, a true HEPA filter, and PlasmaWave technology.

This model is different in that it is a smart model. It comes with WiFi connectivity so that you can hook it up to your phone. The Winix app allows you to control your air purifier from anywhere in the house. It also lets you monitor the air quality in your home from day to day.

Filtration Type5 stages
Filtration Life1 year

If you’re looking for a machine that is suitable for bedrooms or home offices, then this may be the best option for you. We chose the Winix U300 as the best for mid-sized rooms since it covers 300 square feet of space.

This Winix model comes with a more simple look than the other models we have reviewed. It has an elegant white and plain design that won’t stick out in a room. It comes with a 5-stage filtration system.

The five stages include a washable pre-filter, a carbon filter, a true HEPA filter, CleanCel technology, and PlasmaWave technology. One unique thing about this model is the CleanCel function. Winix developed this as an antibacterial treatment that helps eliminate harmful bacteria and virus causing agents.

We liked that this model is ideal for people who want to purify the air in mid-sized rooms. It’s great for bedrooms, which can help prevent head colds while you sleep.

We wished that it came with a remote, but otherwise, you can set it, and the purifier will adjust the fan speed itself. We recommend this product for people who want the extra layer of protection in CleanCel technology.

Best for Small Rooms
Coverage Area150 Sq ft
Filtration Type3 stages
Filtration Life1 year
Noise Level26 – 52 dB

Many consumers may not need a huge and expensive air purifier. If you’re looking for an option that is suitable for a small room or nursery, then this one might work for you. We chose the Winix Freshome P150 as the best for small rooms.

This Winix model comes with a 3-stage filtration system that includes a carbon pre-filter, a true HEPA filter, and PlasmaWave functionality.

It comes in a compact design so that you can put it basically anywhere in the room without it taking up much space. It has an air quality sensor that is similar to the other models that we reviewed.

The carbon pre-filter is washable and helps extend the life of the HEPA filter. It has four fan speeds from quiet to turbo. This model comes with a sleep mode, which dims the lights and quiets the fan.

We thought that this machine was ideal for small offices or nurseries. We liked that it was so compact and easy to move. It probably won’t work as well for people with pets since there’s no pre-filter.

As one user from Home Depot noted, “Easy to set up and works extremely well. Surprising to see all the stuff it’s cleaned out of the air!”

Pros

  • Easy to move around
  • The filter is easy to change

This Winix model is designed in a space-saving tower design. It features 360-degree air filtration that pushes air up into the room. It has a 4-stage filtration system that consists of a pre-filter, carbon filter, true HEPA filter, and PlasmaWave technology.

One thing that we liked about this model is that the tower design allowed for air to circulate and fill the room upwards. It saved a lot of space since the stand is smaller than the other models. We liked that Winix included the smart app control with this model.

According to Joseph, “It really works. The WinixSmart app is great for setting schedules, accessing remotely.”
