Choosing the right Winix air purifier can be a daunting task. With all of the features, filtration, and functionality of each model (and there are many), it can be a hard decision to get the right one for you. This guide to Winix air purifiers will help direct you to the perfect Winix model for your exact needs and preferences.

Choosing Your Filtration

All Winix air purifiers have multiple filters to provide the best possible air quality for the space they are placed in, however, not all models are equal. Each Winix model has a unique offering of 3-stage, 4-stage, and even 5-stage filtration to help cover a wide range of air particles. Let's break these different filtration stages down.

3-Stage

The 3-stage Winix air purifiers have....you guessed it, three filters. These three filters break down as follows:

1. Activated Carbon Filter: This filter reduces VOCs and odors from cooking, pets, smoke, and even formaldehyde for you new house owners! It also helps prolong the True HEPA Filter lifespan. 2. True HEPA Filter: This filter captures 99.99% of airborne allergens including pollen, dust, smoke, pet dander, and other ultrafine particles as tiny as 0.003 microns! 3. PlasmaWave Air Cleaning Technology: Winix PlasmaWave Technology creates hydroxyls to neutralize bacteria and viruses without producing harmful ozone. This replicates nature’s natural, safe, and effective process of cleaning the air. This technology helps reduce viruses and bacteria from the air more effectively, reduces everyday odors, reduces mold growth rates, and increases overall air purification performance.

4-Stage

The 4-stage purifiers have an added level of purification by taking all the filtration from the 3-stage models and adding…

4. Washable, Fine Mesh Pre-Filter: This is good for prolonging the life of your other filters and giving you the convenience of having a filter you can throw in the washer and use again and again without the need to replace it.

5-Stage

If four filters weren't enough, Winix has stepped it up by adding 5-stage air purifier models for the ultimate in air purification. This includes all of the purifications from the Stage 4 purifiers but with one added filter to serve a specific purpose.

5. Pet Pre-Filter: These models intend to serve pet owners! The pet pre filter is in front of the other filters and acts as the first line of defense for pet hair, dander, and visible particles to further provide added filtration to your air and prolong the life of your filters.

CADR

Every Winix air purifier will have a different level of CADR. What is CADR? CADR stands for Clean Air Delivery Rate and it is a measurement of how quickly an air purifier is able to remove contaminants—such as dust, pollen, and smoke—from the air in a room.

Air purifiers with higher CADR ratings will clean the air in a space more quickly than models with a lower CADR rating. So really, CADR is a metric that can help you get the correct air purifier for the size of space it will be operating in.

As a general rule of thumb, you want the CADR number to be at least two-thirds of the total area of the room. If you take a 10x12 room, for example, it has 120 square feet, and therefore, you would want a CADR of at least 80 to have the best air purification performance. Fortunately, Winix has different models to fit multiple CADR needs ranging from 230ft2 all the way to 698ft2 in their most premium XQ model!

Reliable, Certified, and Trusted

Winix is one of the top names in air purifiers, and in every model, you can guarantee the highest quality across the board! All Winix air purifiers are AHAM verified (removing smoke, dust, and pollen from the environment), Energy Star certified (a measure of energy efficiency), and UL certified (meeting specific safety requirements)!

If that wasn't enough, all of the models in the Winix lineup are backed by a two-year warranty. They will gladly repair or replace your model if it has a qualifying issue.

Functionality and Features

Auto Mode

Auto Mode allows you total freedom with your Winix air purifier by allowing you to set it and forget it! It will run only when it senses when your air quality may not be quite up to par.

Smart Sensors

All Winix air purifiers have single, dual, and even triple smart sensors that allow its Auto-Mode feature to run smoothly. These smart sensors measure particles and odors in your air in real time and adjust the fan speed accordingly.

Winix Smart App

Some of the more premium Winix air purifiers include smart features that allow you to pair your phone to your air purifier via the Winix Smart app. This gives you total remote control over your air purifier. With the Winix Smart app, you can manage your filter with up-to-date views of your filters’ remaining life, and you can even purchase new, matching filters for your unit! The app gives you updated indoor and outdoor air quality readings and records your air quality history. Of course, the app also allows you to control the settings and fan speed all from your phone as well!

Air Quality Indicator

Winix air purifier units also provide an air quality indicator directly on the unit by displaying a blue light for good quality, an orange light for fair, and a red light for poor quality to give you current feedback on your air.
