Okay, so I finally caved and bought these STUPIDKID filters after staring at my Levoit Core 300’s ‘replace filter’ light for weeks. The OEM ones are just too pricey, man.

First impressions? They fit PERFECTLY. Like, snap-in-like-OEM perfectly. No weird gaps or struggles—just popped it in and my purifier didn’t even throw a tantrum (you know how gadgets can be).

Performance-wise? Honestly shocked. My allergies haven’t flared up since installing these, and my room smells like… nothing? In a good way? No pet odors, no lingering takeout smells—just crisp air. The 3-stage filtration seems legit: catches dust bunnies, pollen (RIP my sneezes), and even neutralized my roommate’s burnt popcorn incident.

Side note: NO FUNNY SMELLS. Some off-brand filters reek of chemicals, but these? Nada. Just pure, uneventful air.

Value for money? DUH. Half the price of OEM filters, and I got a 2-pack. Pro tip: ALWAYS keep a spare—these babies get dirty faster if you’re a pet owner or live in a dusty area (like me).

Cons? Maybe *slightly* less sturdy than OEM, but for the savings? Worth it. Also, don’t forget to reset your purifier’s filter light (hold the button for 5 secs—life hack!).

Verdict: If you own a Core 300 and hate overspending, these are your new BFFs. OEM who?
