What Is SensorSafe?

The SensorSafe 2.0 chest clip monitors your child’s well-being, sending timely alerts directly to the caregiver’s smartphone if unsafe conditions arise. Originally developed to reduce incidents of children left unattended in vehicles, SensorSafe notifies caregivers if the car is switched off with a child still buckled, if the child unbuckles themselves mid-drive, if the back seat temperature reaches an uncomfortable level, or if a break is needed due to extended seating time. The alert system extends to emergency contacts with GPS coordinates if necessary, ensuring a continuous line of protection.

Works well
This stuff is pretty great I bought it for attaching tomato plants to the fence where the stems were too big to fit my smaller clip ties and even in our strong winds none of the ties have come undone so far

Effective and functional air purifying
Style: Medium Room Air Purifier, Style: Medium Room Air Purifier
This Amazon Basics model AC2224A Air Purifier is a really capable machine with a somewhat unique filter. I ordered it when it was on special and decided to give some detail on the features to help folks who might be new to air purifiers. The filter weighs in at just over 1lb. That's actually pretty heavy for the size. The filter does the standard 3 things people expect, pre-screen, hepa, active carbon adsorption, but it's a little unique in how it is configured. The pre-screen is straight forward and permanently attached to the outside. It should catch big stuff like pet hair to help stretch out the more expensive layers. Most other filters run a single layer of hepa then separately on the inside run a layer of activated carbon - either as mesh or pellets. Here the filter stitches the hepa and the active carbon together. The active carbon is actually small chunks about the size of sugar crystals layered inside. (yes, I found the end and cut off a pieces to check it out). That actually is a very thoughful way to do it. Activated carbon is structurally changed in the factory to increase its surface area. It's a process you can't replicate at home. The activation allows it to adsorb molecules that cause odor and VOCs. I've given you an illuminated photo of the inside of the filter so that if you can zoom in you'll see the random strands which the hepa standards require. Random strands improve filtering and add strength for the filter. The risk with running a layered filter like this is that if it's constructed poorly it will block airflow. I can check those aspects and on high speed the machine pulls under 30watts and puts out just shy of a 9mph air flow. That's good work. Air flow does create air noise which I measured at 65db directly on top of the machine. It drops another 10db a foot away. On the sleep mode I get 42db on top and that actually drops below the 30db I can measure once you're a foot away from the machine. So, it's capable of power and of being quiet. The last thing is the automation. There is an air sensor on the back by where the cord plugs in that measures the PM2.5 levels. I know what mine are (I have multiple purifiers and sensors), so it doesn't surprise me in the least that on auto the machine drops down to the lowest level. You can also turn on a light that then adds a color to indicate the air purity. I use either essential oil or incense to test the sensor. This was very responsive and noted the essential oil mist I was diffusing right away. It turned the light red and sped to its highest level. Once it had cleaned up the issue it slowed back down and returned to its peaceful green color. It gives solid performance that is in no way basic. Plus, there's the added advantage that you're familiar with the company behind it.

Fresh Air, Quiet Performance, and Easy Setup
Style: Medium Room Air Purifier
Great air purifier! It was super easy to set up and started working right away. The noise level is low, even on higher settings, and the air in my room feels noticeably fresher. It’s compact, looks nice, and fits well in smaller spaces. Definitely a solid buy if you want something simple and effective.

Good air purifier - make sure you actually unwrap the filter lol
Style: Medium Room Air Purifier
I'm an idiot and didn't realize the filter that comes already inside it was in there wrapped in plastic for some reason that surpasses my understanding (the whole unit was already wrapped in plastic, why is the filter, which is inside the plastic-wrapped unit, also wrapped in its own separate plastic?? As if we need more plastic in the world...). Anyway, I didn't look inside cuz I thought the filter would just be installed in there and I plugged it in and cheerfully ran it for months til it told me it was time for replace the filter then bought a second filter and went tk take my old one out only to realize I hadn't been filtering anything all that time 😅 oops. Lol. So yeah, make sure you unwrap the filter. Otherwise it's a good little air purifier. Now that the filter is actually installed right, I notice it kicks up higher when we cook or do anything that would lower air quality, so it does seem to be detecting that properly! My allergies do seem better overall. It's pretty quiet when it's on low, but does get loud when it kicks up. I'm OK with that since it pretty much only happens when we cook or if I just put out a candle or something.
