If you're looking for a way to turn any screen (including those in hotel rooms) into your own smart TV, you may be interested in this sale on a few Amazon streaming sticks. The discounts come as part of the company's Big Spring Sale, underway now. One stick to call out is the Fire TV Stick 4K Max, which is down to $40 after a 33 percent discount. That matches the record low we saw for this latest model of Amazon's most advanced streaming stick, a price it has hit a few times this year. 

As the name indicates, the Fire TV Stick 4K Max supports 4K video, as well as Wi-Fi 6E, Dolby Vision, HDR10+ and Dolby Atmos audio. It has more internal storage than the Fire Stick 4K and quicker processor. It comes with an Alexa remote, which lets you find stuff to watch just by talking. Speaking of Alexa, a Fire TV stick also allows your screen to act as a smart home hub of sorts, letting you control your smart lights and check in on your connected cameras. 

The Amazon Fire TV Stick Lite is also included in the sale. We named that one the best budget pick in our guide to streaming devices and right now it's down to $20, a 33 percent discount off the $30 price tag. That's not an all-time low, we saw it dip to $15 for Prime Day in July. But if you don't want to wait to see if Amazon discount it again this summer, this is perfectly respectable deal. 

The Stick Lite a good way to get access to Amazon's free content, which is extensive, plus the Fire TV OS interface does a fine job of looping in any streaming app you subscribe too (though it does heavily favor Amazon content). The stick even includes a voice remote. One thing the remote can't do is control your TV's on/off switch or adjust the volume. It also doesn't support 4K video, but if you don't have a super high-def screen anyway, that point is moot.  

If you want even more free stuff to watch, you may want to check out our top pick for free and live content, the Roku Streaming Stick 4K. It's on sale for 22 percent off, or $39, a price it sells for fairly often.

The top smart air purifier in our guide is Levoit's Core 400S Smart Air Purifier, which is currently down to $190 as part of Amazon's Big Spring Sale. Just be sure to click the on-page coupon to take $30 off the list price. The discount is the largest we've seen this year, though the unit did dip to $179 in 2022's Black Friday sale. In our tests, the unit performed better than some of its more expensive competitors and the filters are reasonably priced at $50 (other purifiers require replacements topping $100). 

Air purifiers can be a good option for days when the pollen count is high or there's yet another wildfire burning in your region — in other words when opening a window to let in fresh air isn't an option. The Core 400S Smart purifier can auto-detect when there's high particulate matter in the air, adjusting the fan speed accordingly. And fortunately, the highest speed isn't disturbingly loud, yet still circulates a good amount of air. The on-board controls are easy and the connected app is fairly easy to set schedules and the like — after you get past the superfluous forums, wellness and shopping tabs in the over-stuffed app. 

It uses a three-stage system comprised of a pre filter to catch pet hair and larger dust particles, then a activated carbon layer for trapping odors and VOCs. Then there's a HEPA filter to remove pollen, mold and even some bacteria from the air. The machine is also Energy Star and CARB certified. The design isn't the most inspired, but the Core 400S does its job well.

Your keys (bags, jackets, purses) may soon become easier to find, thanks to the Big Spring Sale at Amazon. Right now a four pack of Tile Pro Bluetooth trackers are down to $80 instead of the $100 full price for the pack. The deal looks even better when you consider a single Tile Pro goes for $35. That's not quite an all-time low, as we saw the set drop to around $70 for the shopping holidays in 2022 and again last year. Still a decent savings over buying our favorite trackers for Android phones separately and at full price. 

The Tile Pro lets you swap out the battery, unlike other Tile models where you need to replace the whole unit. It's also louder than other Tile trackers and Apple's AirTag. While Tile trackers will work with Apple and Android phones, we found the connectivity to be much more reliable with an Android device. Like AirTags, the tags rely on the millions of other Tile users to anonymously ping your lost items when they're out in the world. At home, you can make them ring using the app to help you figure out which couch cushion your keys have fallen between. One caveat is that some features, like the alerts that let you know when you've left your items behind, are only available with a monthly subscription. 

Other Tile trackers are on sale as well, including the smaller Tile Mate and the Mate paired up with a Tile Slim, our pick for the best wallet tracker. If you're interested in our top overall Bluetooth tracker, it's worth noting that the Chipolo One is on sale for $60 for a four-pack. It was the loudest tracker and the quickest at letting you know when you were leaving the house (or restaurant, coffee shop, grandma's house) without your things. Though it's wider finding community is nowhere near as vast as Apple's or even Tile's.
