About this item

Built for Wide Room Coverage

This air purifier is structured for rooms up to 2400 ft², supporting steady air circulation across larger indoor spaces. Its cylindrical housing enables 360-degree air intake and outlet, allowing air to move evenly through the unit. The internal system uses a multi-stage filter setup with a pre-filter, HEPA layer, and activated carbon section. A 24-watt power rating supports continuous operation with controlled energy use.

Real Time Air Data Feedback

The unit operates on a DC 100–240V input and uses a capacitive touch panel for direct control. Multiple fan speeds allow adjustment based on room conditions, while auto mode responds to real-time PM2.5 readings. An integrated infrared sensor tracks airborne particle levels and updates the digital display continuously. The timer function supports scheduled operation across different time intervals. Sleep mode lowers sound output to approximately 22 dB for reduced noise during nighttime use. The HEPA filtration layer captures particles down to 0.3 microns as part of the internal system.

The base-access filter compartment allows straightforward removal and installation without tools. Its compact size make it manageable to reposition between rooms. An integrated tray allows optional use of fragrance pads without altering the filtration structure.

it handles our open-concept living and dining area no problem. previous purifier we had could barely keep up with a single room half this size, always felt like it was struggling. this one just quietly does its thing and the air actually feels cleaner.

My last air purifier was so loud I had to turn it off at night to sleep. This one runs quietly enough that I actually forget it's on, even on the medium setting. Total game changer for our bedroom.

Really happy with this purchase.

Filters on my old unit were impossible to find after about a year and the company basically stopped supporting the model. This one uses a standard HEPA setup and replacements are easy to track down. No weird proprietary nonsense ❤️.

Solid.

Good quality and easy to maintain. Filter replacement is straightforward and the unit itself feels well built.

HIGHLY RECOMMEND!

The dual cycle filter system is something I actually notice working. The first stage catches the bigger stuff and then the HEPA layer handles the fine particles. You can see the difference in what collects on each filter, which honestly tells you a lot about the air quality in your home.

Covers our whole main floor, which I honestly didn't expect. Very impressed.

Very pleased with this. It handles our large living room without any issues and runs smoothly day and night.

IT JUST WORKS 🌿!

Simple to operate and does a thorough job. I can tell the difference on days when I forget to turn it on.

told my coworker to get one of these after she kept complaining about pet dander making her sneeze every morning. she had the same worry I did about filters being a pain to replace, but she said it was super easy and her allergies are way better now.

ok this thing is actually so good, my allergies have been so much better since I got it.

great for a big room

What I appreciate is how it handles a large space without cranking up to jet-engine mode. The PM2.5 sensor display updates in real time and you can watch the numbers drop after cooking or after someone tracks in dust. Really satisfying to see it reacting.

Does exactly what it says. Clean air, quiet operation, no complaints.

Ran it after a dusty renovation project and the difference in an hour was noticeable. The HEPA filtration catches the really fine particles that most purifiers miss, and the dual filter setup means it isn't getting clogged as fast as a single-stage unit would.

the coverage on this is genuinely impressive for the square footage. I have it in the corner of my living room and it pulls air from across the whole space. The intake design seems well thought out, not like some units that only clean the air right next to them.

This has been running consistently since I got it and I have zero issues with it. The air quality in our home feels noticeably better and my family has commented on it too.
