7 Best air purifier for eczema 2023

The advancement of medicine has cured almost every disease known to mankind. All except the allergic reactions of our body to different things. People with skin allergies tend to develop itchy skin when coming in contact with the allergen. Therefore, you need an air purifier to keep the air free from all allergens and things that trigger them. If you are like me then, the painful irritation of eczema can become very hard to deal with. An air purifier is an excellent addition to your home as a good quality air purifier can reduce the chances of allergic reactions by simply removing dust and other small particles from the air.

What is eczema?

Eczema is a skin condition where the skin becomes inflamed, itchy, red, cracked, and very rough. However, eczema is not limited to these symptoms only. It is a general term used to describe different skin conditions like atopic and contact dermatitis and dysphoric and nummular eczema.

Eczema can cause annoying irritation and itchiness, yet the sole cause of this is unknown. The skin of those who suffer from eczema may start to blister if not appropriately treated. On average, about one in every 10 people suffers from eczema at some point in their life. However, most cases clear up during adolescence.

What are the effects of eczema?

Eczema is caused by an allergic reaction. In the case of atopic dermatitis, particles of pollen, dust, and mites in the air may all contribute to an outbreak. However, these allergens are not limited to airborne particles only. As a matter of fact, many people are allergic to various metals and elements. People with allergic reactions to certain metals, latex, or other chemicals may experience eczema outbreaks after coming into physical contact with the offending material.


Interesting facts about eczema


How does an air purifier help?

Airborne particles like dust, mites, and pollens contribute to the outbreak of eczema in one way or the other. Therefore, you need a device that can clear the air from such harmful particles and make your environment fresh & healthy. There are some air purifiers in the market that include HEPA filters. Such machines remove dust, allergens, molds, and even mycotoxins from the air.

The cleansing process completes in three to four stages, respectively. First, the allergen element releases microparticles in the air through the corrosion or oxidation process. These particles are of different shapes and sizes, and therefore a single mesh filter can’t filter them. Second, the air purifier takes this toxic air from the input and passes from basic mesh filters that clear the dust and larger allergen particles. However, some micro-sized particles are still present in the air. Next, the filtered air passes from the HEPA filter that can clear up to 0.3 macro units of particles. At this stage, the air is clean, fresh, and free from any allergens. Therefore, the air purifier finally releases the air back into the room.
