Dehumidifier vs air purifier

Differences between an air purifier and a dehumidifier

An air purifier puts air through a filter that removes airborne pollutants, such as dust or smoke particles and even pollen, that a dehumidifier cannot. A dehumidifier can prevent mold growth because it removes spores from the air. However, because it cannot control the humidity level in the home, excessive humidity can cause mold to return.
Dehumidifier vs air purifier

The main function of a dehumidifier is to remove excess moisture from the air and reduce the humidity level in the room. While this device does not clean or filter the air, it does help remove allergens such as mold and dust mites that breed in humid or damp environments. At humidity levels less than 50%, these sources of allergies and asthma wither and die.

Air purifier pros

Purifying the air in the apartment from harmful impurities makes it healthier, even if the consumer lives in a polluted city. Removal of allergens, pollen, tobacco smoke, soot from the air makes life much easier for allergy sufferers, especially it is important during exacerbation of the disease. Removal of bacteria, viruses allows during epidemics to resist the spread of infection, to prevent an increase in the number of sick family members. Cleaning with ozonation helps to disinfect the air, creating a feeling of freshness, like after a thunderstorm.

Air purifier cons

Quality air purification from impurities can provide only expensive equipment, which can significantly hit the pocket of the consumer. Purifiers with ozonation function should be used after consultation with specialists, because in large quantities ozone is poisonous and can be harmful to health. Air purifiers with replaceable filters require constant maintenance, if this process is started, the device will lose its cleaning functions, becoming a source of germs.  A photocatalytic air purifier purifies the air from viruses and bacteria by 97-98% due to its functions, but it is not recommended for children’s rooms due to the sterility of the air obtained, which affects the child’s immunity, lacking sources for resistance. The choice of an air purifier should be made with the help of a specialist for maximum effect of purification from the right impurities. The wrong air purifier, at best, will do no harm, at worst, will make the occupants of the apartment continue to breathe polluted air, further damaging their health.

Dehumidifier pros

The advantages of condensing household dehumidifiers include their low cost, mobility and low power consumption.

Dehumidifier cons

Relative disadvantages include the fact that condensing household dehumidifiers work effectively in areas where the temperature does not drop below 15 degrees and they can not dry the air below 40% relative humidity (although the temperature in the living room below 15 degrees – is not normal, and the relative humidity of 40-45% – is optimal and even more lower humidity is simply not required).

 

Should you get a dehumidifier or an air purifier?

When choosing a device for an apartment, first of all you need to determine:

The area and volume of the room to be cleaned – the instruction to the device specifies the area of the room or the volume of air to be cleaned, these values should not be exceeded, otherwise the effect of the purifier will not work. Required modes of operation in terms of time (uninterrupted continuous operation or occasional use) – some models are not designed for 24-hour operation, they have a high power consumption, or they require constant maintenance to replace or clean the filters. Noise level requirements – purifiers with a fan make a lot of noise, you need to take this factor into account, choose either low-power or low-noise purifiers if there is a limit. Harmful air impurities to deal with – different types of purifiers have a narrow functional focus – some may be better at cleaning coarse construction dust, but not at removing tobacco smoke, viruses, allergens, others – on the contrary. The need for humidification, fragrance – humidification of dry air, additional saturation with selected fragrances is chosen individually.

 

Air Purifier vs. Dehumidifier: Comparison Chart

  Air Purifier Dehumidifier
Target To circulate and filter the air, trapping dust, smoke and other allergens. To reduce ambient humidity.
Humidity levels Can change Use when humidity is over 50%
Types Filter, Ionization, Ozone generators, Adsorbents, UV light Mechanical/Cooling, Air Conditioners, Adsorption/Dehydration, Electronic, Ion Membrane, Homemade
Destination Useful for allergy sufferers and asthmatics because they reduce or eliminate dust, secondary tobacco smoke and other airborne allergens. Recommended to relieve allergies by removing mold, dust mites and fungus from the air.

 

Can you use a dehumidifier and air purifier in the same room?

You can. As long as some simple rules are followed for the location of the units in the room. Do not direct the steam (fog) jet from the humidifier at the cleaner. This is especially true for electronic cleaners (ionizers, electrostatic, photocatalytic, etc.). It is advisable to maintain some distance between the devices, the more the better.

 

Can air purifiers dehumidify?

An air purifier only captures particles of pollutants such as dust, dust mites, pet hair, pet dander, mold, pollen, etc., it cannot reduce the humidity in the air.

 

Should I get a humidifier or air purifier?

Air purifiers are suitable for people who live near industrial areas and highways, or if there are renovations going on in the next room. For those who are allergic to dust, pollen and wool. The cleaner also gets rid of unpleasant odors like tobacco smoke. 

If the humidity in the room is less than the minimum, it is bad for health – dry eyes, exacerbation of lung and respiratory diseases. Doctors advise to avoid excessive dryness of the air by getting plants and fish in an aquarium, as well as constantly cleaning the floors. If all these options do not suit you, the only thing left is to buy a humidifier.
