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.

A budget air purifier should still use real HEPA media and should not generate ozone as a byproduct. For this page we include only air purifiers priced at $160 or less that run on a true HEPA filter and are not ozone generators. We treat "HEPA-type" or ozone-emitting units as disqualified, no matter how cheap they are. In our scoring, price alone never earns a spot here - the unit has to clear the cleaning-method bar first.

How we score: We require a device price at or below $160, a real HEPA filter, and no ozone-generating function, then rank the qualifiers by our composite score. The composite reflects filtration, honest room-size coverage, running cost, and other rubric dimensions, so a low sticker price does not move a unit up on its own.

FAQ

What makes an air purifier count as budget here?
We cap this list at a device price of $160 or less. We also require a real HEPA filter and no ozone-generating function, so a cheap unit that uses HEPA-type media or emits ozone does not qualify regardless of 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 rather than sticker price alone.
Why do you exclude ozone-generating purifiers even when they are inexpensive?
We treat ozone generators as disqualified for this list. The EPA states that ozone can be harmful to breathe at levels these devices can produce indoors, so in our view a low price does not offset that, and we require units here to have no ozone-generating function.
