Amazon Prime Day 2021 is wrapping up, but there are still several outstanding deals on air purifiers from the top brands in the industry, including Dyson, Alen, Blueair, and more. The sales are running now through midnight PDT, and we’ll be watching deals and updating this post as we come across more and better deals, so come back often to find the latest discounts.

The air inside your home may not be as clean as you think. Evidence suggests that most indoor air is actually more polluted than outdoor air, according to the Environmental Protection Agency. Pollen, pet dander, and fumes from cleaning supplies are just some of the indoor pollutants most of us come across every day. Air purifiers provide an easy and affordable way to make the air in your home fresher.

You must be a Prime member to take advantage of these air purifier deals. By signing up right now for a free 30-day trial of Amazon Prime, you can gain access to these deals and many more.

The best Prime Day deals on air purifiers right now

Air purifiers come with a variety of features and are priced to fit most budgets. We cover the deals on our favorite models below, all of which we’ve tested and have proven to do a good job of cleaning air. We also look at how loud air purifiers are, long-term costs (for filters and electricity), portability, and more. For more details, see our air purifier guide.

What is the best air purifier on the market?

Our favorite air purifiers range in price from under $100 to up to $650. The best air purifier for your needs will depend on how much space you want the unit to clean, your budget, and which special features are important to you. Our top budget pick is the Lasko LP300 HEPA Tower Air Purifier. Though we haven’t seen it on sale (yet), a larger, more powerful version, the LP450, is at an all-time low price. The LP300 did a good job in our air purifying tests and has low filter replacement costs. Plus, it can clean all of the air in a 219-square-foot room every 15 minutes.

If you’re looking for high-end features, the Blueair HealthProtect 7470i Smart Air Purifier is the way to go, though we’re not seeing any Prime Day deals from Blueair just yet. You can control it with Google Assistant or Alexa, and the Blueair app (available for iOS and Android) supplies detailed readouts of your air quality while giving you control of the unit from anywhere you have WiFi.

Can an air purifier prevent the spread of COVID-19?

According to the EPA, an air purifier on its own is not enough to protect against COVID-19. Yet, when you use it in conjunction with the Centers for Disease Control and Prevention’s recommended best practices, including social distancing and hand washing, an air purifier can be part of a protection plan for your household.

How do we determine if an air purifier deal is worth it?

The air purifier deals on Prime Day are some of the best this year. To determine this, we compare against historical price data and recommend a new deal if it’s better or similar to what we’ve seen in past years. We will also recommend deals that beat the average price from the last three months. In addition, we look at competing sales happening at the same time.

We mostly pay attention to deals for air purifiers that appear in our air purifier buying guide because we want to ensure you’re buying quality products. All of the air purifiers in our guide have been thoroughly tested so we can stand by their quality and performance. For those we haven’t tested, we employ thorough research and look at reliable brands that make other air purifiers we’ve tested.
