Prime Day 2025 is coming soon on July 8-11, but you don't have to wait to grab good tech deals — and that goes for everyone, not just Prime members. Early deals have already started popping up on Amazon, and one of the best at the moment is on an Engadget-approved air purifier. The Levoit Core 400S air purifier is on sale for $183, which is $37 off its usual price and not too far off of the lowest price we've seen. It's part of a larger sale on all kinds of Levoit devices including other air purifiers, cordless vacuums and more.
The Levoit Core 400S is our current pick for the best air purifier overall. Sure, it might not have the prettiest design of all the options we have tested and the companion app might have a little too much going on. But the Core 400S does its job and does it well.


This smart air purifier is slated to clean the atmosphere in spaces of up to 1,733 square feet in as little as one hour. The Core 400S has a cylindrical shape with vents at the top and a touch display that shows air quality readings. You'll be able to get a sense of the current air quality in your space at a glance with a color-changing ring that will light up in blue, green, orange or red. The 360-degree filtration system is said to be capable of capturing over 99.9 percent of pollutants as small as 0.3 microns, such as dust, pet dander and pollen.
There is an auto mode that should suffice for maintaining air quality, but the Core 400S is compatible with Alexa and Google Assistant voice controls too. The fan isn't too loud, even when it's operating at maximum speed — the volume topped out at 62dB in our testing.
Meanwhile, at $50 each, the air filter replacements aren't too expensive compared with those from many of Levoit's competitors. You can also find other Levoit Prime Day deals on Amazon right now that include more air purifiers, cordless vacuums and more.This article originally appeared on Engadget at https://www.engadget.com/deals/pick-up-our-favorite-air-purifier-while-its-37-off-for-prime-day-143224711.html?src=rss

    "Great, another ‘essential’ gadget to clutter my life. But hey, at least Engadget gets paid if I cave. 😏"

    For a more thoughtful take:
    "Solid review, but does the Core 400S actually outperform cheaper alternatives? Or just Engadget’s paywall?"

    "Caution: I'm not convinced by the glowing review. I've heard mixed reports about Levoit's reliability and the effectiveness of their air purifiers in real-world settings. Anyone else have experience with this brand?"

    Do air purifiers truly enhance health, or are they just another trendy gadget? I'd love to hear about any research supporting their effectiveness.

    **"Engadget’s pick? Great—but why not support local brands too? Big tech reviews often overlook smaller, affordable purifiers that work just as well. Let’s demand better choices, not just corporate favorites!"**
