Air Purifier vs Dehumidifier | KARK

What is the difference between an air purifier and a dehumidifier?

We all struggle at times to maintain the perfect level of comfort in our own homes. If your home is getting too humid and stuffy or starting to give off a slight odor, it might be time to think about investing in a solution.

While air purifiers and dehumidifiers can accomplish some of the same goals, primarily for those with allergies, there are critical differences between the two products. Purifiers filter the air and remove any harmful or irritating particles, while dehumidifiers essentially draw moisture from the air, thereby decreasing overall humidity levels. By comparing the functions of each, you can make a more informed decision for your personal needs.

Why choose an air purifier?

As clean air initiatives become more mainstream when it comes to the environment, having clean, fresh air inside your home is also essential. Air purifiers filter out large and small particles, many of which can cause allergic reactions, irritation, and other health issues.

As we learn more about how air purification and circulation play such an important role in the spread of harmful aerosols and other particles, having a quality air purifier helps to make indoor spaces safer and more comfortable for everyone.

What You’ll Love About Air Purifiers

  • Portability: There are many small and very portable personal air purifiers available today. These models can easily be moved from room to room depending on where and when they are needed.
  • Filter options: Always look for an air purifier with a HEPA filter, as it can filter out the smallest airborne particles. Some models may even feature one or two pre-filters designed to capture larger particles before they even reach the main HEPA filter.
  • Good for allergy sufferers: Anyone with seasonal allergies caused by pollen, allergies to dust and pet dander, or sensitivity to smoke will benefit from using an air purifier. By reducing the overall amount of irritants in the air in your home, you will be able to breathe easier.
  • Reduces odors: Air purifiers that use more than one filter help minimize odors caused by smoke, pets, food, and other sources.
  • Helps eliminate viruses: Different air filters will have size ratings that indicate the smallest particles they can filter. Although they do not completely eliminate all viruses, they can get rid of larger particles that facilitate viral transport. Many air purifiers also contain UV lamps designed to kill harmful viruses.

What You Should Consider About Air Purifiers

  • Room size: Before buying an air filter, you need to make sure you choose a model that can filter the entire space you want. Large rooms may require more powerful air purifiers than small bedrooms or offices.
  • Price: Air purifiers aren’t always the most affordable product for those on a tight budget, but you can find quality options ranging from around $100 to $1,000 or more. You will also want to consider the cost of replacement filters.
  • Noise: In general, many modern air purifiers tend to be quiet, but some produce more noise than some people prefer. Check the decibel rating if fan noise is an issue.

Why choose a dehumidifier?

Although they don’t typically filter your air, dehumidifiers have unique benefits that can improve your health and quality of life. By removing excess moisture from the air, dehumidifiers can help you keep indoor humidity at a stable and desirable level, for a more comfortable home.

People with asthma can also benefit from using a dehumidifier, as too much humidity can make it harder to breathe.

What You’ll Love About Dehumidifiers

  • Reduces mold, mildew and dust mites: When you regularly use dehumidifiers in homes with high humidity, you won’t have to worry about the growth of mold, mildew and dust mites that can lead to allergy attacks.
  • Helps food stay fresh: Many types of dry foods and grains are best kept in areas with low humidity.
  • Minimizes odors: By using a dehumidifier to help reduce excessively humid or damp areas of your home, you can reduce unwanted musty and musty odors.
  • Easy to use controls: Dehumidifiers tend to have simple controls and may even offer convenient preset options.

What You Should Consider About Dehumidifiers

  • Noise level: Similar to purifiers, dehumidifiers can sometimes create background noise. Choose a quiet option if you plan to use one in your bedroom overnight.
  • Tank size: Water removed from the air stores in a removable tank. People who live in humid climates may want to opt for a model with a larger tank size so you don’t have to empty it as often.
  • Price: Your overall budget will play an important role, as the total cost can range from $30 for mini-capacity models and up to $300 for large-capacity models.
