While it does a great job as an overall air purifier, we believe pet owners will benefit most from its odor-trapping filtration system.

Pros

Cons

How we decided

We purchase every product we review with our own funds — we never accept anything from product manufacturers.

An air purifier costing under $50 will generally work well to clean odors, but has a small effective space, making them most effective for an office or other enclosed area. Not all of the air purifiers at this price point come with a high efficiency particulate air (HEPA) filter, acting instead as a essential oil diffuser and purifier. Additional available features include automatic shut-off or the ability to add fresh scent back into the air after purification. They generally offer a compact design that will fit easily on a table, desk, or shelf space.
