Difference Between Air Purifier and Dehumidifier (With Table)

When we clean our homes and change the stuff from one place to another, we suffer from the contaminated air. It has a solution by modern technology. The air purifier and dehumidifier will remove the dust and small polluted particles in the air. It makes the air suitable to breathe. Allergic and asthma patients may use the air purifier and dehumidifier. Both have excellent features, and many brands are available.

Air Purifier vs Dehumidifier

The difference between air purifiers and dehumidifiers is that the purpose they used. The air purifiers are used for circulating and filtering the air by deceiving dust, smoke, and other allergens. The dehumidifiers are used for reducing the moisture content in the surrounding area. The air purifiers are used in different humidity levels, while dehumidifiers are using in the humidity levels above 50%. Both are applying for various persistence.

The air purifier is an air cleaner that can clean the air by removing dust particles. It improves the air quality for better breathing. The contaminated air can causes breathing-related diseases like asthma. The air purifiers are for two purposes for homes and factories. The air purifiers for homes are smaller in size, and for factories, they are giant. The air purifiers are produced by techniques called pressure swing adsorbers or other adsorption techniques.

The dehumidifier is an electronic device used to maintain the humidity range. Generally, it is used for medical or comfort speculations. The dehumidifier can eliminate the poor odor and inhibit the growth of fungus by extracting the water from the air. The dehumidifiers are used in households, factories, storage warehouses, and swimming pools. A dehumidifier is an electrical appliance that needs electricity to run.

What is Air Purifier?

From 1830 to 1850, many people got the patent for air purifiers with different mechanisms. The first residential or industrial air purifiers were sold by HEPA in Germany in 1963 by brothers Manfred and Klaus Hammes. Air purifier aims to remove the dust, powder, pet wrath, fungus spores, and insect excretions can act as allergens, triggering allergies in sensitive people. It also excludes the smoke particles and volatile organic compounds (VOCs) that may cause death.

The air purifier has two types of air purifying technologies. They are active and passive methods. Active air purifiers discharge negatively charged ions into the air, causing pollutants to attach to coverings, while passive air purification units use air filters to remove pollutants. Passive purifiers are more recommend cause it is more effective than active purifiers. The passive purifier can eliminate the dust permanently and collect it in the filters. Despite many techniques are available, High-Efficiency Particulate Air(HEPA) is used since 2005.

The air purifier can pressure the air in the room and trap the dust in the filters by various methods. They are Ultraviolet germicidal irradiation, Activated carbon, Photocatalytic oxidation, Ionizer purifiers, and Reactive Oxygen Species (ROS) Technology. The air purifier producing ozone that is harmful to the environment. Many people raise voice against to withdraw the air purifiers producing ozone.

What is Dehumidifier?

The dehumidifier can extract the water from the air and maintain the moisture content. In 1902, American inventor Willis Carrier introduced his first dehumidifier. Refrigeration is the most common method used in dehumidifiers. The evaporators in the refrigerator can draw the moist from the air. There are three types of evaporators used in dehumidifiers. They are coiled tunnel, blade and device, and microchannel technology.

There are two types of dehumidifiers. They are condensation dehumidifiers and desiccant dehumidifiers. The condensate dehumidifiers act as refrigerators to collect the water that is called greywater. Many industries make this greywater into portable drinking water using reverse osmosis filters. Desiccant dehumidifiers are absorbent. It mixes moisture with silica gel and is portable for home use only. Commercial units use a hot air recovery system to remove the humid air.

The dehumidifiers are used in the construction sites to remove the mold and to maintain the humidity. In industries, it is used as climatic chambers in the treatment plants to remove the settlement of fungus that causes damage to the products. Condensate gathering trays and receptacles may need special cleaning to remove trash buildup and prevent clogging of drainage passages. If you need to avoid microbial growth, then the device must be cleaned regularly.

Main Differences Between Air Purifier and Dehumidifier

  1. The air purifier can remove the dust particles and clean the air, and the dehumidifier can maintain the humidity levels in the room.
  2. Air purifiers can clean the air, and Dehumidifiers can reduce poor odor.
  3. The humidity level for air purifiers varies, and the humidity level for the dehumidifier is above 50%.
  4. The air purifier has a multi filtration stage, and Dehumidifiers have a single filtration stage.
  5. Air purifier needs quarter or annual cleaning, and dehumidifiers need regular cleaning.

Conclusion

The air purifier and dehumidifier are electronic devices used to remove the dust particles in the air. Both have distinct purposes. The air purifiers can clean the air and make the air suitable to breathe. The dehumidifier can maintain the moisture content on the air by extracting the water in the air. Allergic patients may use air purifiers in their homes. Many industries and hospitals use an air purifier to clean the air and a dehumidifier to maintain moisture. The treatment plants in industries are using dehumidifiers to prevent fungus growth. Both have unique purposes and objects.
