Fixing Mold Issues

Best Air Purifier For Mold In 2020

Mold and mildew are fungi that typically thrive in any moist environment. Fungi are basic microscopic organisms that play an integral role in the breaking down of dead organic matter and the regeneration of soil. 

When mold comes into your house, however, it can be a big problem. Mold growth can be black, brown, white, or green, and can eventually form a thick layer on surfaces in damp areas. Mildew is a fungus in its early stage of development. It’s a type of mold and typically grows on indoor surfaces like tiles and organic materials like wood.

Mold grows in colonies and creates spores which are airborne. Mold spores can land on close by damp and organic surfaces, which is how colonies typically spread which can be prevented with a air purifier for mold.

Mold and mildew growth can be incredibly detrimental to the health of the people who live inside a house. Spores are allergens, and it can even cause conditions such as asthma. Other common symptoms include coughing, stuffy nose, and throat irritation. Exposure to mold and mildew over long periods of time can lead to the development of an allergy.

Fortunately, you don’t have to live with mold and mildew in your home. Mold air purifiers can kill spores and prevent colonies from spreading. Let’s take a look at the best air purifier for mold and mildew growth in your home.

Mold & Mildew & Health & Air Purifier

Mold and mildew in your home can make you sick. Even if you are perfectly healthy with no history of allergies, it can irritate your eyes, skin, nose, throat, and lungs. If you are allergic to mold, however, your reaction to mildew and mold spores can even be more severe and can result in shortness of breath or asthma, that's why Moon River Chattel has this air purifier for mold review for you. 

People who are not allergic to fungi or spores can develop an allergy over time, especially if there is mold in their living space. An allergy is an overreaction from your immune system to a foreign substance. 

Children, seniors, or people with conditions that compromise their immune systems such as HIV, cancer, liver disease may also have a physiological reaction or discomfort when they inhale or come into contact with mold or mildew. If you have chronic lung disease, you may also be more sensitive to fungi infestations. 

Fungi do not only cause problems relating to health. Mold and mildew can also grow on artworks, furniture, wooden floors, and other surfaces where it can cause a lot of damage. 

Preventing mold contamination should, therefore, be one of your main priorities when it comes to the maintenance of your property. There are many ways to stop the growth of this debilitating organism. 

Since mold and mildew develop in damp areas, it comes down to controlling humidity levels in your home and ensuring proper ventilation of damp areas like bathrooms, laundry, and cooking areas. 

Controlling the spreading of mold spores prevents the spread of colonies. One effective way to eliminate mold is by using an air purifier that filters the air and captures mold spores and other elements. 

Let’s take a look at best air purifier for mold and how they can help to eliminate mold growth from the inside of your home. 

How Does an Air Purifier Help with Mold?

An air purifier is a practical accessory to remove and prevent the development of fungus colonies. True HEPA filters are the most effective for eliminating mustiness. Since there is no moisture in the filter, you don’t have to worry about mold growth on the inside of your air purifier. 

If you live in an area with high humidity, however, it may be a good idea to use a filter with an antimicrobial treatment.

It is not always possible to locate a must infestation. Air purifiers can eliminate these contaminants without you having to know where they are. M​​​​old spreads with airborne spores that land on wet or organic surfaces. Since purifiers trap these spores, they lose their means of replication.  

If you are dealing with an established infestation, use the services of a licensed contractor to remove the mold. Using an air purifier afterward will prevent mold growth from forming again.  

Because mold spores’ sizes typically range from 1 to 30 microns, choose an air purifier that can trap airborne particles as small as 0.30 microns. These filters will also remove other allergens such as dust and pet dander. 

Some units have a UV light to kill spores. Although this is a handy feature that increases the purifiers effectiveness in dealing with mildew and mold, it can increase the cost of the purifier. A True HEPA filter with high-end performance motor will be sufficient to remove spores and prevent mold growth.  

Mold and mildew tend to emit a rotten or damp earthy smell that can be quite unpleasant. Make sure that your air purifier has an activated carbon filter to remove odors. Carbon is a natural substance that neutralizes odors to give your home a fresh smell, especially if mold is embedded into a surface and difficult to remove. 

It can be hard to see physical evidence of mold growth in your home. If you or members of your family experiences symptoms like irritation or allergies, the chances are that you are dealing with mold or mildew.  

An air purifier that is permanently on at a low setting can be the most effective cleanser and mold remover in your home. It will also ensure that the air in your home is clean and free from other pollutants such as dander and dust. 

When you shop for a purifier, make sure that you choose a unit that has a True HEPA filter that can capture particles as small as 0.3 microns. Also, only buy a unit that has an activated carbon filter to control moldy smells in your house. 

Although a UV light can help to kill spores, it may not be worth the more expensive price tag. The SilverOnyx in our list, however, provides you with a highly effective UV-C light at an affordable price. 

An additional buying consideration is the area coverage. The Alen BreatheSmart covers a whopping 1,100 square feet and is suitable for mold control in large rooms. Incidentally, it also has an antimicrobial filter, making it the best option if you live in a high-humidity area. 

Air purifiers like the Coway AP-1512HH cover small areas, but they are portable and more suitable for bedside use.  

The air purifiers in this list can make significant changes to you and your family’s health. Invest in best air purifier for mold today to ensure clean indoor air.
