Let me start by saying these filters are a game-changer for my Levoit LV-H132 purifier. The 3-in-1 system (pre-filter, H13 HEPA, and activated carbon) really does trap everything – from my cat’s endless fur tumbleweeds to last night’s garlic-heavy dinner smells.
The installation is stupidly easy. No tools, no fuss – just pop it in like changing a battery. I swap mine every 4 months (with two cats and a dust-prone apartment), and the difference in air quality is noticeable within hours.
What surprised me most? These outperform some pricier brands I’ve tried. My purifier runs quieter with these filters, and the dust accumulation visible when replacing them proves they’re working hard.
Pro tip: Buy the multipack. At this price point (especially compared to OEM filters), stocking up makes total sense. The carbon layer does lose effectiveness over time, so regular changes are key for odor control.
Minor gripe: I wish the packaging indicated which side faces inward, but that’s nitpicking. For the money, these deliver exceptional value without compromising on filtration quality.
