1. Best value Prime Big Day Deal: Winix 5510 ($129.99 — 28% off)
If you were thinking of buying the air purifier that replaced the new discontinued 5500-2, then now is the time to do it.
Based on historical pricing data, $129.99 is the lowest price for the new Winix 5510 making this Prime Big Day deal a steal for this replacement for the super popular (and now discontinued) Winix 5500-2.
The 5510 comes with an onboard air quality sensor, which unlocks auto mode and an LED air quality indicator light. You also get app support and the option to disable the PlasmaWave ionizer.
Particle removal speed is excellent but the downside is that this model is louder at top speed than most other mid-sized air purifiers with similar performance.

2. Best budget Prime Day deal: Coway Airmega 100S ($60.31 — 25% off)
Our top-rated Coway models is available on Amazon at a historically low price.
At this price, the Coway Airmega 100S offers significantly more value than many other small air purifiers on the market.
The Coway 100S was able to match the speed of the Winix A230, and during this Prime Day big deal, it’s even cheaper!
The Coway 100S is a similar size to many other smaller air purifiers on the market. Be aware it’s doesn’t come with app support but I do really how the light at the top adjusts depending on the level of air quality.
3. Best for large spaces: Levoit Core 600S ($249.00 — 22% off)
This high-performing of the Levoit Core series is now available in grey and also comes at a historically low price
While normally found for over $300, the Levoit Core 600S is now less than $250 and gives you the option of grey or white chassis and you also get access to the onboard laser sensor via the Vesync app which has had significant upgrades over the years.
At top speed, Core 600S managed to clean our test room in 16 minutes, which is excellent performance considering its affordable cost.
The standard filter has 160 grams of carbon but can be upgraded to 360 grams with the Pet Allergy, Smoke Remover, or Toxin Absorber.
I am glad to report that all the improvements you see today in Levoit’s app have been rolled out across even the older devices, including our three-year-old Core 600S.

4. Best for design: Coway Airmega 250S ($246.05 — 38% off)
I loved the design of the Coway Airmega 250S especially the super easy to use removable pre-filter
Normally found closer to $400, you can now get the sleek modern design of both the 250S (app) and 250 (non app) version for under $250.
The bonded filter includes pelleted carbon and a True HEPA filter.
Much quieter than older Coway models at top speed and still powerful enough for medium sized rooms.
Whilst I would love to see more than 3 speeds, the control panel is super simple and has auto mode thanks to it’s on board optical particle sensor.

Frequently asked questions about Amazon Prime Day deals
Amazon first launched Prime Day in the summer of 2015, celebrating the 20th anniversary of the company. Since day one, Prime Day has encouraged other retailers to use the time to release their own deals, so it is a good time to find good prices for big purchases. Worth the wait if you’re planning to buy something expensive!
Many products are sold during Prime Day, from air purifiers to other household devices. That’s why we recommend using this time to make big purchases that you had planned to do already. Many Amazon products, like the Kindle, are found at historically low prices too.
The short answer: yes.
BUT if you are not a member and you have found a great deal, then you don’t need to miss it: Just grab the 30-day free trial so you can buy all the deals, and then go to the subscriptions page to cancel the Prime membership afterwards if you know you won’t need the benefits of Amazon Prime outside of Prime Day.
It started on 7th October and will run until 8th October 2025, but some other retailers will run sales throughout the week.
I love Amazon, but many items are not great, so try to avoid blind searches and look at those specific brands and products you already know about to check if the price has changed.
There is no point in saving a load of money on one of the air purifier deals above just to spend another $200 on stuff you don’t need or a product that doesn’t live up to expectations.
Also, be aware that deals run out, so try to purchase before this happens.
