Review on 🔍 4 Pack Replacement Filters for LEVOIT LV-H128 / PUURVSAS (HM669A) / ROVACS (RV60) Air Purifiers - Includes 3-in-1 HEPA Filter, Activated Carbon Filter, and Pre-Filter by Jero Fontaine

This product looks like the manufacturer's filter that came with the unit. And it fits the device very well. But it's definitely not the same quality. With these filters, the amount of air leaving the unit is much larger. That means they're not that good; do not catch such small particles as ordinary ones. The thinner the filter, the greater the air resistance. And the air through these filters blows very hard. I doubt these are HEPA filters. But they look and have the same carbon base as the originals. But definitely not the same quality.
