Review on 🔍 Efficient Clean Replacement Filters for Lift Away: Enhance Filtration Performance by Kevin Carr

The round foam and round flat filters work great on my NV501, but the HEPA filter WILL NOT FIT, it's too big. I've already replaced a Foam and a Flat before trying HEPA and I need them way more than HEPA so I eat up the cost. But BEWARE this is advertised inaccurately and I don't know how to check if it fits so check HEPA compliance first so you can return it if it doesn't suit you. Even if it was the right part, I would happily give it 5 stars.
