The best dehumidifier and air purifier setup depends on room size. An air purifier and dehumidifier 2 in 1 unit, also sold as a 2 in 1 dehumidifier and air purifier or simply a dehumidifier purifier, does two jobs: it pulls water out of the air and pushes the air through a filter. That sounds ideal for allergies and mold, and for a small room it can be. The catch is capacity. Most dehumidifier air purifier 2-in-1 units on the market are small thermoelectric dehumidifiers with a HEPA-style filter added, so they remove ounces of water a day, not pints.
A regular compressor dehumidifier does have a filter, but it is a coarse dust screen to protect the coils, not a HEPA filter that captures fine particles.

Best 2 in 1 dehumidifier and air purifier (best HEPA dehumidifier)
Tenergy Sorbi Dehumidifier with HEPA Air Purifier
The Tenergy Sorbi is the best 2 in 1 dehumidifier and air purifier option we found with published specs. It combines a thermoelectric dehumidifier (Tenergy: about 750 ml a day at 86F and 80% humidity, 1 liter tank) with what Tenergy calls a True HEPA filter, for rooms up to 200 sq ft. That also makes it the best HEPA dehumidifier for a closet, small bathroom or dorm room. For anything bigger, buy two machines.

Does Dyson make a dehumidifier?
Not that we could find. Dyson's combination machines are purifier and humidifier models (the Purifier Humidify+Cool line), which add moisture rather than remove it. If you see a "Dyson dehumidifier and air purifier" listing, check the product name: you most likely want a dehumidifier plus a separate purifier instead.
LG PuriCare dehumidifier
LG has sold dehumidifiers under the PuriCare name, and a 2023 Reviewed article named LG's PuriCare its top-tested dehumidifier. We could not confirm which LG PuriCare dehumidifier models are currently sold new in the U.S., so we do not list one here. If you find one, check its ENERGY STAR record and the CPSC recall database before buying, as with any dehumidifier.
Combo vs separate units
| 2-in-1 combo | Dehumidifier + purifier | |
|---|---|---|
| Water removal | Low (ounces a day) | High (20 to 50 pints a day) |
| Filtration | Small HEPA-style filter | Choose a purifier sized for the room |
| Space | One small box | Two machines |
| Cost | One budget purchase | Two purchases |
| Best for | Closets, small baths, dorms | Bedrooms, basements, allergy sufferers |
For most people, the best air purifier and dehumidifier all in one is actually two machines. A dehumidifier and air purifier in one only makes sense for very small spaces.
