2024 Air Purifier Reviews

Winix Review 2 Star Rating

Winix

2 Star Rating
  • Pricing: $119.99 - $1,099.99
  • Coverage: 230 - 698 square feet
  • True HEPA filtration, air quality indicator, auto mode, multiple fan speeds
  • Some models: WiFi and Alexa compatible
  • Quiet operation

Winix, a South Korean company established over 50 years ago, specializes in developing and manufacturing healthy home appliances. Their product range includes air purifiers, water filtration systems, humidifiers, dehumidifiers, and other comfort-focused devices. Their air purifier lineup includes 16 options.

Standard features across the range

Winix sells air purifiers in three room sizes: small, medium, and large. You'll find some common features in all Winix air purifiers, no matter their size. These include:

  • True HEPA filtration (captures 99.97% of airborne particles)
  • PlasmaWave Technology (advanced air cleaning, but see our notes below)
  • Air quality indicator with LED lights
  • Auto mode (adjusts based on air quality)
  • Filter replacement indicator
  • Multiple fan speeds

Two small models at $120

The small models, A231 and A230, are both priced at $119.99 and work for rooms up to 230 square feet. Users like them because they can be used right out of the box (after putting in the filters) and for how quiet they are.

Medium-sized models offer more features at varying price points

The medium-sized models, including the C535, C545, 5300-2, AM90, and 5500-2, are designed for rooms up to 360 square feet. Prices range from $149.99 to $249.99. Some models, like the C545 and AM90, have smart features like WiFi and Alexa compatibility. The bestseller is the C535, which is also the cheapest model in this size. If the reviews on Winix's website are to be believed, it has an average of 4.7 stars from 132 ratings. Nothing in these reviews jumped out at us - people are generally happy with how this model performs.

Large models cater to bigger spaces with advanced features

For larger rooms, Winix offers the 9800, XLC, and XQ models. These are priced from $329.99 to $1,099.99 and are suitable for rooms from 500 to 698 square feet. All large models feature 4-stage True HEPA filtration, WiFi connectivity, and Alexa compatibility. The highest priced XQ model has the highest Clean Air Delivery Rate ratings (419 for smoke) and includes additional features like a child lock and triple smart sensors. Unfortunately, though, 0 out of its 5 reviewers would recommend it. Apparently, this thousand-dollar air purifier has a tendency to work just past its 2-year warranty and then die. Winix won't budge on the timeframe, either - if it's out of warranty, it's out of warranty.

PlasmaWave Technology: more hype than help

PlasmaWave Technology in Winix air purifiers is a bipolar ion generator that is claimed to neutralize air pollutants. This technology breaks apart water molecules to create positive and negative ions that combine with pollutants. It's essentially an ionizer, which can produce small amounts of ozone. (Ozone in your air purifier? That's a bit like fighting fire with... more fire.) Recent studies have shown mixed results for this technology. Some volatile organic compounds (VOCs) decreased, while others increased. If you have asthma or other lung conditions, you might want to be cautious - ozone can trigger symptoms, and many people choose to turn this "feature” off due to potential side effects like nausea and headaches. (To these customers' chagrin, PlasmaWave has to be manually turned off every time you power on your air purifier for most models.) While Winix claims PlasmaWave is safe and doesn't produce harmful ozone levels, some experts suggest it may not significantly improve air quality and could even slightly degrade it. (In other words, it might be more marketing hype than actual help for your air quality.)

Replacement filters are stunningly expensive

Perhaps the most concerning thing about Winix is the markup on their replacement filters. Where most air purifier companies charge around $30 each, Winix's base prices are as high as $80 to $150, depending on the model. One angry customer (who was otherwise satisfied with their air purifier until the filter died 3 months in) rants, "Let's do some basic math. Walmart sells a purifier with 2 filters for $150 or I can come to Winix and buy a filter for $80? That's so dumb. Disgusting what greed does to people."

Best Air Purifiers

Bad grade from the BBB

It's a similar story in the "Complaints” section of Winix's Better Business Bureau listing, where they have a "D-” grade. One reviewer hopes "they end up in a class action lawsuit for price gouging.” Another calls customer service "a joke”. According to that reviewer, Winix's customer service agents are neither professional nor polite.

2-year warranty dependent on using Winix filters

Winix offers a standard 2-year warranty for most of their air purifiers, but don't get too excited. While they promise to repair or replace defective parts, the fine print is where things get tricky. You'll need to use only authorized dealers, stick to their manual religiously, and use only genuine Winix filters (which, don't forget, are outrageously expensive). As for returns, you've got 30 days, and you'll be footing the bill for shipping it back. And if you're thinking about getting an extended warranty? Tough luck - Winix doesn't offer them.

Bottom line: Winix air purifiers aren't worth the hassle

The drawbacks of Winix's air purifiers are far more obvious than the benefits. You'll face exorbitant filter replacement costs, questionable customer service, and a restrictive warranty. The touted PlasmaWave technology may do more harm than good. Despite some positive user experiences, the overall value proposition is weak. You're better off exploring other brands that offer similar performance without the (perhaps literal) headaches and hidden costs of Winix air purifiers.

Which Air Purifier is the Best?

Imagine coming home after a long day, only to be greeted by a stuffy atmosphere and a musty smell in your living room. You open the windows, but the outdoor air carries in pollen that makes you sneeze. Sound familiar? An air purifier might be just what you need.

These devices can help remove pollutants, allergens, and odors from the air to make your space cleaner and more comfortable. While not a substitute for other preventive measures, air purifiers with HEPA filters may also help reduce the risk of airborne transmission of viruses, including the one that causes COVID-19, by removing particles from the air.

Air Purifier FAQ

Air purifiers are machines that clean the air in a room or in an entire home or office. They remove pollutants like pollen, pet dander, and dust mites from the air you breathe. Given that the EPA says that the level of indoor pollutants can be as much as five times higher than outdoors, it's obvious why so many people use an air purifier to breathe easy!
An air purifier draws in the air from the environment, passes it through a filter that catches pollutants and/or odors (depending on the filtration type you choose), and pushes out clean air into the room. Some purifiers are portable, while others are installed with your HVAC system to clean the air in your whole house.
HEPA stands for High-Efficiency Particulate Air; these filters remove 99.97% of any particles that are 0.3 microns or larger, making them the best choice if you're trying to remove dust mite residue, pollen and pet dander particles from your air. Carbon filters target chemicals and odors, like cigarette smoke, kitchen smells, pet odor, and so on.
They can be - but they don't have to be. You can find small single-room air purifiers for under $60, but most fall in the $200-$700 range. Whole-house air purification systems are going to be the most costly, usually from $1,000 to $5,000+ (which includes professional installation). And, don't forget to factor in the cost of filters, which will need to be replaced periodically depending on the manufacturer's recommendations.
Check the instructions on your machine. Yours may have filters that can be cleaned and reused, or they may have to be replaced every time. Expect your air purifier to have anywhere from 2-6 filters that need to be changed every 6-12 months - but again, be sure to read the specs on your particular air purifier and follow the recommended maintenance schedule.
Most manufacturers recommend running your air purifier continuously. If yours comes with multiple speeds, you can set it to a lower speed while you're away to save energy and then turn it up when you return.
That depends on the machine you choose. If you buy a portable one designed to cover a single room, it will typically cover up to 700 sq.ft. Read the specs carefully to determine if the air purifier you're considering will be effective in the space where you intend to use it. For larger-scale air purification, a whole-house model might be a better investment.
Not necessarily. Most machines will be louder when you first turn them on, to get a good start on cleaning the air in the room you're in. But, once the pollutants have largely been removed, the fan speed usually slows down automatically for quieter operation. They're typically not much louder than a portable fan.

Continued from above...

Many people can benefit from using an air purifier. If you have allergies or asthma, an air purifier can help reduce symptoms by removing irritants like pollen, dust, and pet dander from the air. If you live in an area with high pollution levels or wildfires, an air purifier can help filter out harmful particles. Even if you don't have specific health concerns, an air purifier can help improve overall air quality and eliminate unpleasant odors.

There are several types of air purifiers available, each using different technologies to clean the air. HEPA (High-Efficiency Particulate Air) filters are the most common. They can remove 99.97% of particles as small as 0.3 microns. This includes dust, pollen, and some bacteria.

Activated carbon filters are great for removing odors and gasses. They work well for getting rid of cooking smells, smoke, and chemical fumes.

UV-C light purifiers use ultraviolet light to kill bacteria and viruses. They're often combined with other types of filters for more thorough air cleaning.

Ionizers release negatively charged ions that attach to airborne particles, making them too heavy to stay in the air. However, ionizers can produce ozone, which can be harmful to your health.

When shopping for an air purifier online, consider the following factors:

  • Room size. Make sure the purifier is rated for the size of the room where you'll use it. Each air purifier is designed to clean a specific amount of air, usually measured in square feet. Choosing one that's too small for your space won't effectively clean the air.
  • Filter replacement cost. Look into how often filters need to be replaced and how much they cost. Some purifiers have filters that need to be replaced every few months, while others can last up to a year. Factor in these ongoing costs when making your decision.
  • Noise level. Consider how loud the purifier is, especially if you'll use it in a bedroom. Air purifiers can range from nearly silent to quite noisy. If you're sensitive to sound, look for models with lower decibel ratings or those with "sleep" or "quiet" modes.
  • Energy efficiency. Check the energy consumption to avoid high electricity bills. Look for Energy Star certified models, which use less energy than standard air purifiers without sacrificing performance.
  • Additional features. Decide if you want extras like air quality sensors, remote controls, or smart capabilities. These features can make your air purifier more convenient to use but may also increase the price. Consider which ones are truly important to you.
