My Experience With Coway Airmega Vs. Levoit

Back in January 2025, my allergies were a nightmare, with dust piling up from my dog’s shedding and city smog creeping through every crack, turning my home into a sneeze zone.

I’d had enough of waking up congested and sneezing through meals, so I ordered the Coway Airmega 400S for $250 and the Levoit Core 400S for $200 on February 1, eager to test their promises of clean air and see which would give me back my peaceful nights.

I set them up in my 800-square-foot apartment—one in the living room, one in the bedroom—and the journey began with high hopes.

On February 2, I fired up the Airmega 400S in my living room, and within 20 minutes, the smoky haze from a cooking mishap with burnt toast vanished, thanks to its impressive 400 CFM pollen CADR that tackled my seasonal woes

. The app let me tweak settings from my couch, and the quiet 24.4 dB hum on low was a soothing backdrop to my evening TV, though the 12.3-pound weight made moving it a slight workout, especially when I shifted it to clean underneath. The pre-filter caught dog hair like a champ, reducing my vacuuming, but I noticed a slight plastic smell at first that lingered for a few days, prompting me to air out the room.

Switching to the Levoit Core 400S on February 5, I ran it during a dusty cleaning day after rearranging furniture, and its 260 CFM CADR cleared the air in about 25 minutes, a bit slower but still effective for my needs.

The 24 dB low setting was just as soothing, blending into my background noise, and at 11.6 pounds, it felt lighter to shift around, a relief when I moved it to the bedroom. The app was intuitive, with an air quality sensor that kicked in automatically during a pollen spike, but I missed the Airmega’s higher CADR for those particularly pollen-heavy spring days that left me reaching for tissues.

By March 10, rainy weather brought mold spores into my home, turning my bedroom into a damp challenge, and the Airmega’s True HEPA filter tackled them with precision, reducing my sniffles by morning.

I vacuumed the pre-filter weekly, a quick task that kept it humming, and the carbon layer cut cooking odors from my kitchen experiments, though the 77W max power draw showed up on my electricity bill, making me rethink long runs. The Levoit handled the same room well, its HEPA-grade filter doing solid work against the mold, and the 28W max kept costs lower, a perk I noticed, though I had to stir more to avoid uneven air flow in corners.

On April 5, after two months, I tested both during a BBQ smoke test in my backyard-turned-kitchen due to a grill mishap. The Airmega’s 328 CFM smoke CADR cleared the lingering haze in 15 minutes, impressing a friend who dropped by with allergies, while the Levoit took 20 minutes, still effective but lagging slightly behind in speed.

Both had dishwasher-safe filters that were a breeze to swap out, and I loved the Levoit’s portability for a camping trip, tucking it into my car with ease, though the Airmega’s sturdier build felt more reliable during a windy night outdoors.

May 20’s heatwave kept my windows shut to block the sticky outdoor air, and the Airmega’s smart mode adjusted fan speed during a spicy stir-fry that filled the house with fumes, keeping noise at a manageable 52.8 dB on high—noticeable but tolerable during a movie night.

The Levoit’s 51.8 dB high setting was a tad quieter, a subtle edge, and its sensor dimmed lights for sleep, a nice touch that helped me drift off, though I had to reposition it to avoid a draft. A coworker’s old purifier fizzled out mid-conversation, leaving her coughing, which made me appreciate these upgrades even more as I started experimenting with air quality apps.

July 1 marked five months, and the Airmega’s filter held strong after a pet hair storm from my dog’s latest shed, though the $80 replacement cost stung when I ordered it online. The Levoit’s $50 filter wore faster with the same storm but saved cash, a trade-off I tracked, and I began noting air quality readings in a journal to compare effectiveness.

By August 15, both hummed steadily in cooler weather, with the Airmega excelling during a dusty renovation and the Levoit shining for quiet nights, and at 01:45 AM +06 on August 30, 2025, after a late-night run to test pollen levels, I’ve got the full story—let’s find your winner!
