What makes an air purifier count as budget here?

We cap this list at a device price of $160 or less. On top of that, a unit still has to use a real HEPA filter and have no ozone-generating function - so a cheap unit running HEPA-type media or emitting ozone doesn't make the page, no matter how low the price.

Is the cheapest unit the best pick?

Not in our ranking. The Levoit Core 300S at $149.99 leads on composite score, while a sub-$50 option like the MOOKA B-D02L sits near the bottom in our scoring. We rank by composite, which weighs filtration and running cost - so the lowest sticker price isn't the thing that wins.

Why do you exclude ozone-generating purifiers even when they are inexpensive?

We treat ozone generators as disqualified here. The EPA states that ozone can be harmful to breathe at levels these devices can produce indoors, so in our view a low price doesn't offset that - which is why every unit on this page has to have no ozone-generating function.

Best Budget Air Purifier

Bottom line

In our scoring the Levoit Core 300S (composite 7.1) is the best budget air purifier, leading on its H13 HEPA filter, low $45 annual filter cost, and no ozone, with the lower-priced GermGuardian AC4825E (composite 6.9) close behind.

Shopping on a budget doesn't mean settling for less than real HEPA media or putting up with a unit that gives off ozone. So this page includes only air purifiers priced at $160 or less that run a true HEPA filter and aren't ozone generators - we treat "HEPA-type" or ozone-emitting units as disqualified, however cheap they are. Price alone never earns a spot here; a unit has to clear the cleaning-method bar first.

How we score: To qualify, a unit has to come in at $160 or less, use a real HEPA filter, and have no ozone-generating function - then we rank the survivors by our composite score. That score reflects filtration, honest room-size coverage, running cost, and the rest of our rubric, so a low sticker price doesn't push a unit up on its own.
