You may consider your home a safe haven from allergens. But get this: Even though you can't necessarily tell by looking at it, indoor air is often twice as polluted as outdoor air thanks to dust, mold, and chemicals that accumulate in the enclosed space over time. That's why experts recommend investing in an air purifier, which is known for filtering out allergens from your home and enhancing the quality of your breathing air.

"Some things like dust mites might only be in the air for 20 to 30 minutes, but if something floats around for hours, like cat antigen, dog antigen, cockroaches, or mold, you want an air purifier on to trap it," says Timothy Craig, DO, a professor at Penn State's Center for Allergy, Asthma, and Immunology. Volatile organic compounds (VOCs), which are gasses from cigarette smoke, paints, furniture, copiers, cleaning supplies, and dry-cleaned clothes can also lead to symptoms of "sick building syndrome," like headaches and fatigue.

Below, explore the best air purifiers for allergies that will help alleviate your symptoms and freshen up your home.

The 12 best air purifiers for allergies you can buy:

What to consider when buying an air purifier

When shopping for an air purifier, make sure it uses a HEPA (high-efficiency particulate air) filter. This type of filter meets certain standards set by the United States Department of Energy, like the ability to remove 99.97% of tiny (0.3 micrometer or bigger) airborne particles. Dr. Craig says this type of filter is extremely effective at removing any airborne allergens and should remain on at all times in order to reach its full air-cleaning potential. Just make sure to replace the filter as often as the manufacturer suggests, usually every six months to two years.

Speaking of filtration systems, it's best to opt for a model that contains multiple filters to eliminate more particles from the air. You can also take the air purifier's size and features into consideration to ensure that it will be a right fit for your home. There are options that have automatic sensors and will begin filtering the air on their own, as well as some that have multiple power settings for increased filtration performance and can accommodate large rooms. If you're looking to decrease the allergens in your bedroom so you can wake up well-rested, you'll want to choose an air purifier that has a sleep mode or quiet fan option as to not disturb you.

Other ways you can reduce indoor allergens

An air purifier is just one way that you can reduce the number of airborne allergens in your home. According to Payel Gupta, MD, FACAAI, a New York City-based allergist, household chores like vacuuming and laundry can also make a huge difference.

"Vacuum frequently, give your pets baths more frequently to help with dander, and wash your sheets in hot water at least once a week for dust mite allergies," she tells Health. "It's important to remember that where you sleep should be kept free of animal dander as much as possible. Not allowing your pet to sleep in your room is one of the most effective steps you can take in reducing your exposure to your pet."

Here, we share the best HEPA-filter air purifiers worth trying out for a cleaner, healthier home.

One buyer with a cat went as far as to call it "life changing": "We have two cats in our 4,000-square foot house. When my sister came from out of state, she asked if our cats ran away. She said our home had zero odor or scents, which is what I was going for."

Best for Bedrooms: Levoit Air Purifier

If you're someone that has trouble sleeping because of allergies or always wakes up with scratchy eyes or a stuffy nose, putting an air purifier in your room will help alleviate your symptoms and help you get a good night's sleep.

You can also choose from three filter speeds, depending on the size of your space, and two brightness levels for the nightlight function.

"I've had this purifier for five days and can already tell a huge difference in my allergy and sinus issues," raved a customer. "My right nostril is constantly clogged and by the second day of running this I could finally breathe through both nostrils upon waking. There is a noticeable difference in the air when I walk into my bedroom where I keep the Levoit filter from the rest of my home. No more musty smell. If you have any sort of allergy or breathing problem, I highly recommend this."

Best for Dust: Coway Mighty Air Purifier

It also captures other airborne allergens including pet dander and mold, which can alleviate symptoms related to asthma as well. A built-in air quality sensor alerts the machine when it needs to do double time on eliminating those pesky allergens. If no allergens are detected in a 30-minute span, the machine temporarily turns off to save power.

One reviewer noted just how sensitive it is: "I've had this purifier for 2-1/2 years and still absolutely love it. The filters aren't unreasonably expensive nor do I have to replace them too frequently. It's very sensitive and kicks on when I cook, even though it isn't in the kitchen. In fact, it's so sensitive that a dog fart has been known to get it going to filter the air. If that's not a selling point, I don't know what is."
