Air Purifiers

You wake up in the morning and sneeze several times. Your head is heavy and your nose itches. Your throat feels like it’s lined with needles as you gulp down your morning coffee en route to work, and dark circles under your eyes look back at you in the rearview mirror.

You use half a box of tissues to control your runny nose during the day, and your family can’t stand your constant sniffing throughout the movie that evening.

Or your nose isn’t necessarily runny, but you’re dizzy and have headaches, your tongue, palate and cheeks are swollen that you can’t help biting them.

You don’t have a cold – you’re suffering from allergies.

Does this sound like a typical day for you?

Whether you suffer from occasional seasonal allergies or severe allergic rhinitis, you may be wondering how to alleviate your symptoms and increase your daily comfort.

Waking up congested, groggy, or with a sore throat each morning, taking antihistamine after antihistamine without success, is no way to live.

If you’re doing all you can to alleviate your allergy symptoms (regularly dusting, sweeping, and vacuuming, keeping pets out of the bedroom, avoiding the outdoors during allergy seasons, and taking suitable allergy medication) and still can’t beat your allergies, it may be time to look to technology for relief.

The two most used home appliances for allergy relief are air purifiers and dehumidifiers

These devices work to remove allergens from the air in different ways:


Air purifiers trap smoke, pollen, dust mites and other allergens and recirculate cleaner air into the room.

Dehumidifiers on the other hand, take excess moisture out of the air, making it hard for mould, mildew and dust mites to survive or grow in the first place.  

So which one is right for you and your allergies? Let’s take a closer look.


Do you benefit most from an air purifier or a dehumidifier?

Basically it comes down to this; is the humidity in your home higher than 50%? You probably (and very likely) can benefit tremendously from a dehumidifier.

Does your home have recommended humidity levels? Then you will be best off with an air purifier.

The differences explained

Air Purifier for allergies

Air purifiers may be helpful if your allergies are spurned on by dust mites, pollen and pet hair. These often-airborne irritants can be filtered out by a purifier, leaving you with cleaner air to breathe.

Dehumidifiers for allergies

Dehumidifiers may be helpful if you live in a humid or wet climate. Mould, mildew, dust mites and other allergens thrive in wet environments.

Reducing the humidity in your home (especially in kitchens, bathrooms, under sinks, in garages and basements) can make it impossible for these allergens to thrive.

If your home smells musty, feels stuffy, or you notice condensation on the windows, a dehumidifier may be a fitting solution.

So which is best for allergies?

As we’ve seen this depends on your situation and type of allergy. If your home’s atmosphere is too humid, you may want to opt for a dehumidifier with air purification function. By reducing the humidity to below 50% allergy causing dust mites and mould with wither.

The key is to create a balance in the ideal relative humidity in your home.

Low relative humidity makes it hard for mould and dust mites to survive and can lower indoor air pollution.

Higher humidity levels feel more comfortable to your nasal and throat passage tissues.
