Before You Buy: Four Things Worth Knowing
1. Genuine filters and the filter-life indicator
On LEVOIT Core-series purifiers, the filter life indicator and its reset function are designed to work with authentic filters. Third-party filters may fit physically but can leave the indicator reading incorrectly. If you rely on that reminder, factor it in.
2. Compatibility is usually narrow
Notice how many rows above say only. The LEVOIT Core 300-P filter fits the Core 300-P and 300S-P and nothing else. The Bissell MyAir filter fits the 2780 series alone. Model numbers that look nearly identical often take different filters, so check the exact string printed on your unit rather than the family name.
3. Pre-filters and HEPA filters are different purchases
The Honeywell HRF-A200 and HRF-A300 are pre-filter kits, replaced roughly every three months. The HEPA filter itself lasts around twelve. Buying one when you needed the other is a common mistake.
4. Replacement cost matters more than purchase price
A purifier with a cheap sticker price and a $79 filter set every six months costs more over three years than a pricier unit with an $18 annual filter. Before buying a new purifier, look up its filter cost in the table above and multiply.
Rough Filter Costs

- Blueair Classic 200 Series — around $35
