How To Select The Best Dehumidifiers for Your Allergies

We will quickly consider a few factors that you should look for when deciding on the type of dehumidifier for allergies that you should purchase.

The importance of this cannot be overemphasized. Equipped with this knowledge, you’ll be aware of what to look out for when making your purchase. Likewise, you’ll be convinced to make the right decision at the point of purchase.

The few but important factors that you should put into consideration include the capacity of the device to dehumidify, the water holding capacity of the tank, and the humidity settings automation control of the product.

  • Dehumidifying Capacity

First, let’s clear this.

The capacity of a dehumidifier does not refer to the amount of water you can fill in its tank. Instead, the dehumidifying capacity is measured based on the pints of moisture the device can effectively remove over 24 hours. For instance, when a dehumidifier has a feature of 60 pints, this explains that it will effectively remove 60 pints of moisture from the air in 24 hours.

Although the tank size plays a role in how effective it will function, you may need to empty the tank at intervals. However, when a dehumidifier has a continuous water removal channel, you need not worry.

Just ensure to purchase a unit that will satisfy your needs.

  • Water Tank Capacity

Your dehumidifier may be removing 50 pints of moisture from the air in a day, but it doesn’t imply that the water tank has a storage capacity of 50 pints of water. It may come with a water storage capacity of about 30 pints. That depends on the manufacturer.

This means that you’ll need to figure out how the device will run nonstop all day because a pause in the working process can make the dust mites and other allergens grow and replicate. This can be detrimental to your health.

Just make an effort to purchase one with a large water tank capacity or one with continuing water fill-up and removal system. With that, you won’t have to worry about a thing.

  • Automation

It will not be an easy task for you to have to move often to put off or put on the device when you attain your satisfactory humidity level.

What you should do is find a device with automatic systems that you can set to shut off when it reaches the set humidity level. Automation is advantageous in running your device.

What Should I Do About Space Consideration for my Dehumidifier?

Here is another concept you must understand.

When you are selecting a dehumidifier to buy, you should consider the range of space you want it to work over effectively.

Do you want it just for your room or bathroom? Or, you want it to cover every bit of your home?

If you want a bathroom dehumidifier, you can purchase a portable one and place it in your bathroom. On the other hand, if you are buying a dehumidifier for an apartment, you must obtain a device that you will place strategically to function for your whole house.

The product features or descriptions will give you an insight into this.

Best Dehumidifier For Allergies FAQs

We’ve answered some questions that people often ask when trying to make the right purchasing decision for the best dehumidifier for allergy.

We hope it will add to your insight when making a choice.

  • How fast will a dehumidifier reduce the humidity or moisture?

 This is dependent on the size and the dampness of your room or house. If your home is very damp, the device will have to work over some days or weeks to reach the appropriate humidity level, which is between 45 and 55%. Besides, the device will have to work nonstop. After the dampness is at a minimum, it will take the dehumidifier a few hours to bring the humidity level into control, in a day.

  • Can I drink the water collected from the dehumidifier?

As much as the water collected from dehumidifiers is clean, it is not healthy for consumption. This is because the water contains other particles such as fungal spores, pollens, viruses, amongst others, that are airborne. These airborne particles can be pathogenic, which will render you ill when they find a way to enter your body.

We advise that you take tap water instead of water collected from a dehumidifier.

It is not safe for animals too. It contains a high level of ammonia and nitrites.

  • Is a dehumidifier noisy?

No and Yes. The answer to this question is that it depends on the kind of dehumidifier you are using. Ordinarily, dehumidifiers use a fan. When the fan is set to work faster, you should expect a certain level of noise.

Likewise, some dehumidifiers have compressors, while some do not. Those that have tend to produce more noise compared to those without a compressor.
