Which Type Of Air Purifier Or Dehumidifier Is Better For Health?
Jun 10, 2018

Which type of air purifier or dehumidifier is better for health?
You wake up in the morning and sneeze several times. Your head is heavy and your nose is itchy. Your throat is tingling, and the dark circles in your eyes will look at you in the rearview mirror.

You can use a box of tissues to control the runny nose during the day. That night, your family could not tolerate sneezing all night.

Or your nose may not be flowing, but you are dizzy, have a headache, a swelling of your tongue, cheeks and cheeks, and have anorexia.

You don't have a cold - you have allergies.

Does this sound like a day you often go through?

Whether or not you have occasional seasonal allergies or severe allergic rhinitis, you may want to know how to relieve symptoms and increase your daily comfort.

Wake up every morning to cough up, cough or sore throat, take anti-allergic medicines to be ineffective, unable to live.

If you can do your best to relieve your allergy symptoms (dusting, sweeping and vacuuming regularly, take your pets out of the bedroom, avoid allergy season outdoors, and take appropriate allergy medications), and still cannot beat your allergies, it may be You need technical help.

The two most common allergy household appliances are air purifiers and dehumidifiers

These devices can remove airborne allergens in different ways:

The air purifier captures smoke, pollen, dust mites and other allergens, and recycles clean air into the room.

Dehumidifiers, on the other hand, remove water from the air, making it difficult for molds, molds, and dust mites to survive or grow.

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

Do you have more comfort from an air purifier or dehumidifier?

Basically it comes down to it; is your home's humidity above 50%? You may (probably) benefit tremendously from the dehumidifier.

Does your room have a recommended humidity level? If so, then you'd better use an air purifier.

Is the air in your home really dry? Usually below 40%, the exact percentage depends on the outside temperature, then you may want to have a humidifier. When you experience static, nosebleeds, pruritic eyes, dry skin, etc., you will know that the air is too dry.

Difference explanation

Air Purifier Allergies

If your allergies are dusty, pollen, and pet vomiting, an air purifier may help. These often airborne stimulants can be filtered through purifiers, leaving cleaner air to breathe.


Allergens suspended in the air can be removed.

Small portable version is convenient and cheap.

Is an effective part of multimodal hypersensitivity control.


Although air filtration is recommended medically for allergic patients, it is not a solution by itself.

Excitants such as pet hair and pollen can fall onto the floor and stick to furniture, where air purifiers cannot reach.

When using an air purifier, you still need to take steps to reduce irritation at home, including regular cleaning, vacuuming and dusting.

Air filtration is not instantaneous - most air purifiers require 15-20 minutes to clean one room of air, depending on capacity and fan size.

Cannot control the growth/presence of humidity and mold, mold, dust mites, etc.

Strict maintenance is required - cleaning and filter replacement.

Some models emit ozone, which may be irritating to the lungs.

Remember that if you are allergic to dust mites, you need to know where dust mites cover (mattresses and pillows). Reliance on air purifiers is not enough.

Dehumidifier for allergy

If you live in a humid or humid climate, a home dehumidifier may help. Because molds, molds, dust mites, and other allergens grow rapidly in wet conditions.

Lowering the humidity in the home (especially in the basement, sinks and narrow spaces) may prevent these allergens from thriving.

If your home smells moldy, hot, or you notice condensation on the window or toilet, the dehumidifier may be a suitable solution.


Can limit the growth and cultivation of moist allergens

Maintenance is relatively simple and easy


May cause dry conditions that may irritate the nasal passages

Molds may grow in the drainage basin, so frequent cleaning of the sink is required.

Small models of dehumidifiers can easily fill the tank and require frequent dumping of the collected water.

If your allergic reactions are more susceptible to infection and irritation, and you are unable to properly filter out the dry nasal passages of bacteria, allergens and allergens, you may actually need to

The air in the home adds water and takes us to another option - a humidifier.

Humidifier allergy

The humidifier releases steam or water mist into the air, which helps soften and moisturize the nasal passages, allowing the nose to work comfortably and properly to prevent allergy-related infections.

Humidifier has two advantages:

1. Breathing in the humid air reduces inflammation, which helps to relieve symptoms such as nasal irritation, congestion, and inflammation caused by allergies and drug treatment side effects.

2. Your nasal tissue is more suitable for excreting allergens and irritants, thereby reducing allergy symptoms.

Hospitals use humidifiers to help lung patients and other patients who need to breathe more easily.


Homes that are hot in a hot, dry climate or exposed most of the year can be beneficial

Prevents irritation and infection caused by inhaled air


Some allergens thrive in humid environments, so finding the balance between dry and wet is critical.

When used in an already humid environment, allergies may be exacerbated. Humidity should be kept between 30% and 45-50% - some machines have hygrometers.

Regular cleaning is a necessary condition to prevent the growth of mold, and to prevent the settled allergens from being released into the air together with water.

Control the surrounding humidity, but do not filter the air of the allergen

By maintaining the humidity level below 50%, allergy symptoms caused by house dust mites can be greatly reduced.

Type of allergy device

If you know which device is best for preventing allergies and how it affects your allergy symptoms, now is the time to buy what type of purifier, dehumidifier or humidifier into your home.

After consulting with your doctor to determine if this is feasible, here are some guidelines for your reference.

Air purifier type

1. The HEPA (High Efficiency Particulate Air) filter is made of very fine fibers and can efficiently capture 99.97% of particles larger than 0.3 microns. A HEPA filter usually lasts 2 to 4 years and is usually the most effective air purifier of its own.

2. Ionized air filters use electric fields and particles with opposite charges that attach to pollen and dust and fall to the floor or to the wall where they are less likely to be inhaled. However, the particles can be recycled into the air.

3. The electrostatic air purifier uses a charge to attract the allergen and deposit it on the filter screen. These devices need to be cleaned and are usually not as effective as HEPA filters.

4. Activated carbon air purifiers use carbon filters to trap contaminants without releasing them back into the air. They capture smoke, odors, and chemical emissions most efficiently, but they are less effective at capturing allergens.

UV air purifiers use ultraviolet light to destroy bacteria and viruses. The most effective UV purifiers for allergic patients are also UV purifiers with built-in HEPA or carbon filters, because the UV rays themselves cannot effectively destroy allergens.

Ozone air purifiers produce ozone to reduce odors and fresh air, but cannot filter dust or pollen unless they are used in conjunction with ionizers or filters. Ozone is a lung irritant that can cause other health problems.

The best air purifier activated carbon and HEPA filter for allergies and asthma makes it possible to remove a variety of contaminants including gases, particles and chemicals.

For most families, combining several filtering technologies is the most effective option.

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

Low relative humidity makes it difficult for mold and dust mites to survive and can reduce indoor air pollution.

Higher levels of humidity can make your nasal and throat respiratory tissues feel more comfortable.

Make sure the relative humidity in your home is between 40% and 48%. This will reduce dust mite colonies, while producing a rather moist air, comfortable breathing and will not dry the skin.

To understand the humidity in your home, you can use a hygrometer. Many dehumidifiers or humidifiers are equipped with hygrometers.
