Unbiased Winix Air Purifier Reviews

There is a pretty extensive collection of air purifiers by the Winix company. The air purifier market is basically like a flash flood of fierce competitors. The competition is full of wild claims and one-uppers; some are good, and some brands are sub-par to say the very least. So, how do you know if you are getting a real deal with a true HEPA air purifier or some fancy-sounding advertising that’s nothing like the claims suggest? Well, stick with us to get all the information you need to make a well-informed decision.

The Winix company is a long-standing brand from Seoul, South Korea that has become a worldwide phenomenon. With their cutting-edge PlasmaWave technology in the air purifiers they make, they have a solid reputation that goes all around the world. They also make some impressive dehumidifiers, too. Aside from all that, this is the unbiased truth about the Winix A231 Tower H13, Winix AM90, and Winix 5500-2 air purifiers, models with some of the best capabilities and the best certifications you’ll be glad they have. In addition to the reviews we’ll be bringing you, we’re going to take a brief look at an integral part of understanding how the air cleaner could be right for your living space with the best air purifier by its clean air delivery rate rating (CADR). More importantly, we have the answer to the question, “what makes the CADR rating so important to you and your family?”

Winix A231 Tower H13

The Winix A231 Tower H13 True HEPA Air Purifier 4-stage filter system eliminates the air pollution of a 230 square foot room perfectly. With a few additional minutes, the machine can easily maintain clean air inside a large room, according to the Winix website. The 4-stage air purifying action reduces household odors, VOCs and smoke, pollen, dust, and pet dander.

The Stages of a 4-stage Winix Air Purifier

The first stage 1 is the washable fine mesh pre-filter. This is the first call to defense with the larger particles in the air.

Stage 2 is a true HEPA filter that eliminates 99.97% of impurities and allergens in the air like pollen, pet dander, dust mites, mold spores, microbes, and some viruses. The filter catches the particles 0.3 microns or bigger. That’s huge!

The 3rd stage is an activated carbon filter which effectively reduces VOCs and odors in the home. The carbon filter is a lifesaver, quite literally, for the lifespan longevity of the true HEPA filter. The carbon filter blocks the bigger particles in the air from getting into the HEPA filter. The COA filter requires changing every 90 days or potentially more frequently than that.

Finally, the 4th stage of this home defense system is the patented PlasmaWave air cleaning technology that reduces the impurities in the air more thoroughly.

Winix AM90 With Wi-Fi Capabilities

4-stage Filter

The Winix AM90 Wi-Fi Air Purifier, medium in size, has a 4-stage filter starring the PlasmaWave for greatly reducing allergens like smoke, dust, and pollen lurking in the air.

The activated carbon filter must be replaced every 3 months to keep it working properly.

Certifications and CADR

This product is AHAM certified for a 360 square foot room, yet the Winix website states that the machine cleans a 1,740 square foot room in 1 hour, and as the times get lower so do the square footage of cleaning space; 870 square feet in 30 minutes, 580 square feet in 20 minutes, )and 435 square feet in 15 minutes. This device runs at 65 watts and has a CADR score for dust 233, smoke 230, and pollen 240 each.

Winix 5500-2

The 3-Stage Filter

The final Winix 5500-2 Air Purifier to review has a 3-stage filter. The same reliable protection as the 4-stage filter, this air cleaner has it in 3 stages. The 3-stage filter includes an odor control carbon pre-filter that’s not the same as the activated carbon filter in the 4-stage filtration system. However, the pre-filter is equally efficient. A true HEPA filter, and the PlasmaWave filtration systems, are the same that’s in the 4-stage system to catch and trap the air pollutants that cause allergy flare-ups and microbes that lead to the worst viruses like Covid-19. The smallest particles that the air purifier catches are a minuscule 0.3 microns. The same protection and efficacy are offered in the 3-and-4-stage filters to ensure the best clean air possible.

Clean Air Delivery Rates

The CADR ratings for dust, smoke, and pollen are 243/232/246, respectively. This air purifier is a medium-sized appliance, fit for large and extra-large rooms like the family room or a vast master bedroom or kitchen. The 360 square foot range of good air cleaning is variable in the time it takes the air purifier to clean the air in different sized rooms or areas. The machine can purify a 1,740 square foot space in an hour. An 870 square foot space in 30 minutes, 580 square foot area in 20 minutes, and 435 square feet in 15 minutes. In the regard to the filter lifespan, the washable fine mesh filters can be washed as needed. The COA filters should be replaced every 90 days, more often if the house sees a lot of cooking or the kids spend their time going in and out of the house. Also, the HEPA filter needs to be replaced every 12 months

Features of the 5500-2

The features are incredibly practical. For instance, the dual smart sensor with the auto mode makes the device foolproof. The air purifier machine’s body has a triple sensor to measure the quality of the air in the room, then the auto mode senses the dip in the quality in real-time and kicks on to bring it back up. This particular machine comes with a remote for convenience and an air quality indicator for peace of mind. The automatic sleep mode starts working when the device senses the lights have been turned down, just as it’s in the other devices made by Winix.

The price point is at a fair $249.99 considering the other similar devices’ price points. It doesn’t seem like the Winix company is at all concerned with further improving upon the products, as much as it is with releasing the same quality technology within the existing products in larger, yet more efficient, sized machines. It seems to be A-OK with their customers over on Amazon. The 4.6 out of 5 stars and reviews that credit Winix for saving their lives. Some reviewers were sick when they bought one and are later found some healing. It’s phenomenal! Winix websites reviewers left a total of 4.9 out of 5 stars. Finally, the certifications this air purifier has achieved are the AHAM, Energy Star, and the UL US Listed certifications.

A Complete Guide to CADR for a Good Buy

The most misunderstood concept of in-home air purifier certifications from the AHAM ( Association of Household Appliances Manufacturers), is the CADR. However, if we break it into bite-sized pieces, then it’s really simple. To start this off, the CADR is simply a clean air delivery rate. What’s measured here is the volume of cleaned, or filtered, air with the machine on its highest setting. They measure this way to find out what kind of efficiency and speed the air purifier has. On the other hand, having the device at the lowest speed will yield a lower CADR rate. Because of the difference in speed and input at a lower setting, the air won’t be filtered as quickly as it would on the high setting. Hence, the test is performed on the highest setting, to yield more accurate results consistently. So, the amount of clean air is delivered by cubic square feet in one minute, is the CADR score. After configuring the generalized score, there are separate scores each for pollen, dust, and smoke; the scores will be indicated with backslashes between the numbers, typically. For example, 230/200/180 (the numbers are made up just for the example). The scores for pollen and dust may range from 0-to 450. The score for smoke can range anywhere from 0-to 400. So, the room size is directly affected by the clean air that’s delivered the quickest and most efficiently. So a 90 cubic square foot room, with no high ceilings, will need a purifier with a score of at least 100 CADR. If you have ceilings higher than 8 feet you will add the extra square footage to your CADR when shopping for your new air purifier.

With all the hype about the CADR, it’s a bummer to discover that the certification is completely voluntary for creators of air purifiers. That means not every company will have a rate for the consumer. As good of products as Winix makes, they don’t necessarily have one set number from the AHAM’s tests, but instead, they give you the info based on what sizes of the rooms will be compatible with their CADR number, offering the shopper more options. Like a 1,730 square foot room will clean its air in an hour while the square footage they advertise is the actual room size that the machine cleans the air the fastest, and is really 360 square feet. By putting the information that way, you can gain some perspective on the options the machine has in store for you. Really, the higher the clean air delivery rate the better.
