Best air purifier overall

Rabbit Air MinusA2 (SPA-700A)

Rabbit Air MinusA2Want an air purifier that does it all and looks good while doing it? This Rabbit Air purifier has you covered.

Why we like it

  • Polished design with features like a mood light and light sensor
  • Large coverage area (815 square feet)
  • Washable pre-filter to capture larger particles and extend the life of replaceable filters
  • Multiple air filter layers to combat multiple issues, including a HEPA filter (for very small particles), a carbon filter (for odors), and a customizable filter for individual needs.
  • Negative ion filtering that can be turned on or off
  • Auto air quality monitoring
  • Ability to stand alone or be mounted on a wall

Is it right for you?

There’s a lot to like about this air purifier. It’s a great solution for those who need to cover a large area, combat allergens, and reduce odors all at once. And as one of the most stylish purifiers on the market, it’s a good choice for the more design-conscious consumer.

The main downside? Price. This air filter will set you back about $600. We think it’s worth it for people who need serious filtering, but you might want to try another option on our list if you’re on a tight budget.

Best air purifier for allergies and asthma: Coway AP-1512HH Mighty Air Purifier

Coway Air PurifierThis air purifier is more affordable than the Rabbit Air and still incredibly capable. It’s not as stylish, and it doesn’t cover as much space (361 square feet as opposed to Rabbit Air’s 815), but it is a solid alternative if you’re looking for something simpler and not so pricey.

Why we like it

  • More accessible price than the Rabbit Air purifier (less than half the cost)
  • Quality HEPA filter for removing allergens (pet dander, pollen, etc.) from the air
  • Air quality sensor and auto-monitoring to save energy when the filter isn’t needed
  • Ionizing filter and carbon odor filter to combat germs and smells

Is it right for you?

The Coway is great for those who need an air purifier for allergies and asthma, but not one that has to combat serious odors or cover huge spaces. Plus, it’s less than half the cost of the Rabbit Air, which makes it a great pick for those who need to spend less. The only real drawback is that it covers much smaller areas—however, 361 square feet of coverage should be enough to cover most normal sized bedrooms or living rooms.

Best air purifier for odor (smoke and pet odor): Austin Air HealthMate

Austin Air HealthMateAn air purifier can’t eliminate the health consequences of smoking tobacco, but the right one can do a lot to eliminate unpleasant odors and improve air quality in your home.

Why we like it

  • Stronger activated carbon filter than the competition for serious odor control (15 pounds of activated carbon)
  • Strong activated carbon filter also helps eliminate volatile organic compounds (VOCs)
  • Filters air from all sides, so you have more flexible placement options
  • Huge coverage area (up to 1500 square feet)
  • Includes HEPA filter for small particles, a pre-filter for larger things like pet hair, and a medium filter for everything in between.

Is it right for you?

Got smelly pets or a tobacco smoker in your home? This purifier’s extra-large activated carbon filter can do a lot to eliminate odors in your home. However, it costs about $600, so it isn’t for everyone.

Best air purifier on a budget: GermGuardian AC4825 3-in-1 Air Purifier

GermGuardian Air PurifierNot everyone can spend triple digits on an air purifier. If you want cleaner air but don’t need to worry about serious allergies or odors, the GermGuardian should be able to cover your needs.

Why we like it

  • Affordable price (usually sells for under $100)
  • True HEPA filtering for allergens
  • UVC light filtering to kill bacteria and germs
  • Activated charcoal filter to help fight smells

Is it right for you?

The GermGuardian is probably the purifier for you if you’re on a tight budget. It has a true HEPA filter to combat allergens and a UV-C light to kill germs. It won’t cover as much space as the Rabbit Air, monitor the air quality for you, or have a huge impact on odor, but at less than $100 it is still a great investment for those that need to breathe fresher air.

What should you look for in a home air purifier?

  • A HEPA filter: Every air purifier we recommend comes with a High Efficiency Particulate Air (HEPA) filter, which is a replaceable filter that is 99.97% efficient when filtering anything larger than 0.3 micrometers.
  • Activated carbon: Carbon filters are particularly good at eliminating odors, so if you’re worried about smells, look for a purifier with an activated carbon filter.
  • A washable pre-filter: Almost all air purifiers include filters that have to be replaced periodically. However, if your purifier also has a permanent washable pre-filter, it can catch larger particles and extend the life of the temporary filters.
  • Energy efficiency: Many of the filters on this list can automatically detect air quality, which allows them to run only when needed instead of all day long.
