Here are the best Winix HEPA air purifier products available on the market today:
Winix Air Purifier Features
In their top three models, Winix offers a 5-stage filtration. It starts with a washable pre-filter and ends with their PlasmaWave technology. However, their base model, the 5000B, uses a 3-stage filter. Either way, these features add up to clean air for your home.
First, a washable, anti-microbial pre-filter captures large particles. This extends the life of the unit’s HEPA filter.
Next, an activated carbon filter traps odor and VOCs. But, this filter also uses a nano-silver coating to kills bacteria, germs, or mold spores.
Then, a third stage presents a HEPA filter to remove particles as small as .3 microns.
The final stage is their PlasmaWave technology. This uses Hydroxyl Radicals to kill bacteria and odors at the molecular level. And, it kills organisms without using excessive amounts of ozone.
Smart Sensors and Auto Mode
Winix air purifiers use smart sensors to automatically adjust the unit’s settings. This allows the machine to meet your needs no matter what is in your air.
The Association of Home Appliance Manufacturers is an independent body that rates home appliances so that every participating appliance will have a rating that consumers can compare to others. Winix air purifiers all come with a Clean Air Delivery Rate, or CADR, which measures the amount of dust, pollen, and smoke in the air and rates air purifiers by their ability to clean the air.

Energy Star Certified
All Winix products come with an Energy Star sticker and the guarantee that they won’t drive up your electricity bill. And this is good news for anyone who wants clean air.
Winix HEPA Air Purifier Reviews
Below we cover a few of the models offered by Winix. They design each model for a different set of needs, from small apartment living to multi-pet houses. While Winix does offer a wide variety of purifiers; we think these present some of the best values in their lineup.
Winix PlasmaWave 5300 Air Cleaner
The PlasmaWave 5300 is one of their smaller models, suitable for rooms no larger than 350 square feet. As we mentioned earlier this model only offers a 3-stages of filtration. Yet, the 5300 will still keep the air in your home clean.
Because it is less sophisticated it is priced accordingly. This is one of their more affordable models. In addition to an affordable price, it offers great performance. In fact, it costs less than half the price of similar models from other manufacturers.

We think Winix is one of the best value air purifier manufacturers. With this in mind, it does not make sense that they would be dishonest about their products.
Another point to bring up is Ozone. They often tout that their PlasmaWave™ technology produces Hydroxyl Radicals instead of ozone. Which we feel leads shoppers to believe that “PlasmaWave” means no ozone at all.
However, their units all contain a “corona discharge unit”, which is a small unit within the appliance that generates ozone. Technically, the units produce less than the 0.05ppm. Which is lower than EPA standards for safety. But, we think consumers should know what they’re buying. Ozone is a serious lung irritant. And, anyone with respiratory issues like asthma, bronchitis, or COPD, should know if their purifier emits any ozone at all.
Despite a few mechanical issues, these air purifiers all operate without producing much noise, making them perfect for home use.
Overall, the WAC9500 Ultimate Pet is the best air purifier in this review. The area coverage (250 Square Feet) is a bit smaller than the other two. But, the Ultimate Pet has a 5-stage air cleaner to trap more allergens and air contaminants.
