Whether you realize it or not, there's probably a lot of dust, smoke, chemicals, and allergens floating around in the air of your home. Using chemical cleaners, cooking, living with pets, and even opening your windows can cause the air you breathe to become polluted, creating irritation for people with allergies, asthma, or immune system issues. However, using an air purifier can help to remove harmful particles from your home—and now is a great time to start shopping for one.

Today is the final day of Amazon Prime Day, which means we're scouring the site to find all the best discounts before they're gone. In addition to amazing vacuum deals and huge markdowns on patio furniture and garden decor, we've found some of the lowest prices of the year on top-rated air purifiers. 

The Shark Air Purifier 6 is currently $220 off, and according to reviewers, it's capable of making a noticeable difference in the air quality of your home. With six different fans to help it distribute clean air across spaces up to 1,200 square feet, the Shark Air Purifier 6 is designed to quickly and quietly remove 99.9% of pollutants from your air. Its built-in anti-allergen HEPA filter can capture and remove particles as small as .3 microns—meaning it's fine enough to catch dander, smoke, bacteria, and more. 

We also love that the air purifier tracks the air quality in your home and automatically adjusts its settings to continuously clean your air. You'll be able to see the current air quality of your home by looking at the large digital display at the top of the air purifier. You can also manually adjust the fan speed, check if your filter needs to be replaced, and set a timer. 

Since many airborne allergens can create a bad smell—think smoke, cleaning products, cooking chemicals, pet dander, and more, this air purifier offers odor protection to keep your home smelling fresh. At 32 inches tall, 17 inches wide and 9 inches deep, it won't take up tons of space no matter where you choose to place it. Plus, it comes with a remote control, so you can change the settings from across the room.

Amazon shoppers rave that the Shark Air Purifier drastically changed the air quality in their homes while remaining quiet and easy to use. 

"I literally did not know how bad I needed this product until [my] wife talked me into ordering it," one reviewer said. "Now it is a staple item in our household." The shopper also mentioned how quickly the air purifier reacted to cooking smells after burning microwave popcorn, touting a "noticeable difference in air quality.". 

"We have Newfoundland dogs and two boys under 10 that constantly bring in dirt from outside," another shopper said. "We have this [air purifier] running 24/7 in our living room… It is quiet and effective." They also commented that the air purifier is "super sensitive," mentioning that smoke coming in from an open window will drop the air quality on the digital display to 35%, and the machine will quickly get it back up to 100%. 

"Whenever I'm cooking—even if just using [a] countertop convection oven—it senses the change in air quality and revs up to clean the air," another shopper said, adding, "The Shark keeps the smoke [from] traveling to other areas of the house." The reviewer also raved about how quickly it cleans the air in even large rooms, and how quiet its operation is.
