Right now, 18 states are experiencing poor air quality due to wildfire smoke drifting south from Canada and northern Minnesota. The air quality index for some cities has reached hazardous levels, which means even minutes of being outside could cause intense coughing, wheezing, and irritation of the eyes, throat, and lungs.

I live in Illinois, where the air quality was the worst in the world yesterday. An air purifier is a must-have if you live in the impacted area, and you can get the Blueair Blue Pure 211i Max Air Purifier in the large size for $70 off on Amazon with a coupon. I’ve owned this model for years, and it’s been doing a good job at keeping our home’s air clean over the past few days. 

Since introducing the Blueair air purifier into our living room a few years ago, we’ve seen a significant reduction in the amount of hair that accumulates. The real-time LED indicator provides constant reassurance about the air quality, displaying statuses such as excellent (blue), moderate (orange), or polluted (red).

Blueair says this air purifier removes 99.97% of airborne particles, including viruses and bacteria, dust, pollen, pet dander, and mold. This particular model can clean spaces up to 1,524 square feet in 30 minutes or 635 square feet in about 12.5 minutes when on the highest setting. Plus, it’s super quiet with a decibel rating of 23-53dB — we only really notice the sound getting loud when it’s turned onto the highest setting. 

I highly recommend an air purifier — especially the Blueair Blue Pure 211i Max — to everyone looking to breathe cleaner air this summer, even in unexpected climate conditions.

Setting up a smart home has always involved a bit of ritual—scanning a QR code, opening an app, and waiting for Bluetooth to kick in. To remove this friction, the Connectivity Standards Alliance is releasing the Matter 1.6 update today. While the update is incremental, it’s worth paying attention to as it aims to make setups feel a lot less clunky. Beyond this, the version also introduces Joint Fabric and Thermostat Suggestion features.

Making smart home setups less annoying

Add devices before installation

The headline addition on Matter 1.6 is NFC-based commissioning. This means that instead of the old method of setting up a smart device, the new version now lets you use full NFC exchange for the setup process. You can hold your smartphone to a Matter-certified device without relying on Bluetooth-based flow—even before it’s fully powered on. Multiple devices can also be configured in advance and activated at their final locations.

This could be especially handy for devices that end up in a hard-to-reach spot. A light bulb that needs to go into a ceiling fixture or a wall switch before the mains power is connected. It removes the need to install first and then scan a tiny code from an awkward angle.

Beyond the NFC pairing, CSA is also introducing Joint Fabric if your home is split between different platforms. It features a new way for multiple smart home platforms to share access to devices on a single unified network. Add a bulb once and every platform on the network can see it.

Another new addition is Thermostat Suggestions. It lets smart home platforms send recommendations rather than direct commands that must always be followed. The thermostat then decides whether to follow it based on the user’s preferences, recent manual changes, or current conditions. This is because automations from different apps sometimes clash with each other. For example, if you manually adjust the temperature and a service tries to change it seconds later, the thermostat can recognize the conflict and hold off. The new version also brings smaller improvements, such as security sensors sharing events, standardized device communication across ecosystems, and enabling smoke and CO alarms to flag when they’ve been removed from the wall.

Matter 1.6 is still an incremental update and not a massive overhaul. But the NFC setup gives it an everyday consumer benefit.
