VEWIOR KJ300 Air Purifier for Home Large Room: Real-time PM2.5 sensor with LED display
Meet the VEWIOR Air Purifier—your new best friend for breathing easy in spaces up to a whopping 3000sq.ft. It’s not just any purifier; it’s got a H13 HEPA filter that’s like a magnet for 99.97% of the junk floating around (yes, even that stubborn pet hair and pollen). Plus, with its real-time PM2.5 sensor and LED display, you’ll always know what’s up with your air—literally. It even tweaks itself on the fly to keep things fresh. Talk about smart!
But wait, there’s more (because why stop at just clean air?):
- Sleep Mode: So quiet, you’ll forget it’s there—unless you’re a light sleeper who notices the sound of a pin dropping at 15dB.
- Got preferences? Of course you do. Customizable Settings let you play with 4 fan speeds and timer options (1/2/4/8 hours) to get it just right.
- Smart Alerts: It’ll nudge you when the filter’s had enough—no guessing games.
- And for those days when you need a little extra zen, the Aromatherapy feature lets you drizzle in some essential oils. Because why not turn your living room into a spa?

Air Purifier for Home Large Room
Victoria F.

August 2, 2025
When I first got this VEWIOR purifier, I was super hopeful for better air since I spend a lot of time indoors with my music and concerts on my mind. It did a good job overall, making the room feel less stuffy and handling my husband's allergies better. But oh, the noise! Even in sleep mode, I could hear it humming away, and as a light sleeper, it kept me up some nights. The settings were easy to figure out, thankfully, since I'm not too techy, and I liked being able to set timers. The filter reminders were helpful but came a bit too often, making me wonder if it was really needed. All in all, it's okay, not perfect, but it does the job for now.
- Pros: I super loved how it made the air feel fresh and clean in my large living room, it seemed to grab all the dust and pet hair without a fuss. The display showing the air quality was a nice touch, and I enjoyed adding a drop of essential oils for a spa-like vibe at home :)
- Cons: As it seemed to me, it was a bit noisy even on the quietest setting, which bothered my sleep sometimes, and changing the filter gave me a little hassle with the alerts.
