Do You Suffer From Mold Related Symptoms?

A little occasional wheezing or coughing might seem like a nuisance to many of us. What we don’t realize is that there might be much bigger problems standing behind the symptoms than the simple flu. The slight discomfort can easily turn into a full blown illness. In some cases, mould formation leads to death.

The Environmental Protection Agency (EPA) reports that all types of molds may be dangerous for your health. If you’ve heard that only black mold is a health hazard, you got the wrong information.

The symptoms that people suffer from when exposed may vary. The severity of them can be differ too. They depend on many factors, such as age, overall health condition, your sensitivities or allergies.

People who suffer from mold exposure often experience the following symptoms:

  • Headaches
  • Muscle and/or joint pain
  • Depression
  • Vision problems
  • Immune system problems
  • Fatigue
  • Problems with GI
  • Wheezing
  • Coughing
  • Shortness of breath
  • Anxiety

Each one of these symptoms may be caused by other conditions. However, if you suspect you might have mold in your home, you need to act as soon as possible. The above symptoms don’t all appear at once. They might come and go. You need to carefully watch your health and try to keep the air in your home as clean as possible.

Remember, for most people it’s not what comes to mind when you first experience the above symptoms. Your physician might not be proficient in mould related issues. That’s why when you start experiencing these problems, you might be on your own.

An air purifier can help you keep the air clean and free from spores. While buying an air purifier won’t save you from doing some serious cleaning, it will help you get rid of the symptoms and start enjoying fresh air in your home.

Where to look for Mold?

Wiping the surfaces clean and watching for new growth is compulsory. However, it might not eliminate the problem completely since the mold spores won’t go anywhere. They’ll just settle on another surface and continue flying through the air. If you want to battle the problem that contaminates your home, you need to first find and destroy the source and also get a good air purifier that provides active mold control.

The main problem that we face is the way it reproduces. Fungi send the spores into the air so they find other places to settle. While the spores are airborne, they are invisible. That’s exactly when they cause most of the respiratory problems. Sometimes there are many thousands of spores present in one small room. The spores are usually about 1 to 100 microns in size and easily inhaled. In order to get rid of such particles completely, you’d need to run the air through a high-quality filter that deals with such small contaminants. Most of the air purifiers available on the market today are equipped with HEPA filters that deal with 99.97% of particles 0.3 microns in size. This means they won’t have trouble filtering out the mold spores.

Most Molds typically like damp and humid environments, which is why we usually see many types growing in our bathrooms. Especially around the bath or shower which are exceedingly wet environments that growth can be rampant if left unchecked. Same goes for the toilet.

Spores are very hard to kill. They can survive extremely harsh conditions, including dryness and can stay alive for years waiting for the favorable environment to start growing in. It doesn’t need any specific surfaces to start growing and can live almost anywhere as long as there’s oxygen and moisture.

You can find it on wood, plastic, leather, rocks, tiles, and more. It feeds on whatever surface is beneath it. This is especially unfortunate when that surface is your floor or furniture.

Mold and Mildew start to really kick up into high gear when there is ample moisture around. While the air purifier can help you eliminate the spores in the air, it won’t get rid of the growth. In order to stop the vicious cycle of reproduction, you need to find the mold and then kill the fungi and control the moisture levels.

Look for new growth in the following places:

  • Bathroom (under the sink and around the bathtub)
  • Kitchen (around the sink and under it)
  • Behind appliances that produce moisture (refrigerators, dishwashers, laundry machines)
  • Attic (roof leaks)
  • Around the windows
  • Basements

Before seeing the actual growth, you may first notice a musty odor in you room when the windows are closed. You might also see water stains on your walls or ceiling, discoloration on the carpet and black or white specks on the walls. At the same time, you might start experiencing respiratory problems. This means you have to start fighting the mould and think about reducing the amount of moisture in your home. The humidity levels must be kept below 60 %.

What Type of Mold Do You Have In Your Home?

Microscopic mold spores

There are over 400,000 types of mold in the world. Thankfully, only about a 1,000 can live in the households. These types are divided into three groups.

Allergenic. These types are not dangerous unless you have allergies or respiratory problems, such as asthma. Younger children are especially susceptible to airborne spores.

Pathogenic. These are more dangerous types that can cause infections. They don’t affect 100% healthy people, but if your immune system is compromised, they might cause serious lung diseases.

Toxic. This is the most dangerous group that includes the infamous black mold. This group can affect everyone. They suppress the immune system and may cause cancer. These types all generate mycotoxins that damage your health once inhaled or ingested. You can get adverse effects even after touching them.

In our homes, we mostly face five varieties of mold. They are:

  • Alernaria – settles in your nose, mouth, and upper respiratory tract and can cause allergic reactions
  • Aspergillus – Commonly found in extremely humid climates. It settles on the house dust and can produce mycotoxins, which cause various lung infections.
  • Cladosporium – This one settles on textiles, wood, and other porous surfaces. It can cause hay fever and asthma.
  • Penicillium – Likes to grow on wallpaper, carpets, and fiberglass insulation. It can cause asthma and allergies. May produce mycotoxins.
  • Stachybotrys – Toxic mold aka black mold that generates mycotoxins and causes serious problems, such as lung bleeding. It’s much less common in the households than the other four types. It can settle on wood or paper, but not on tiles or concrete.

How Can You Get Rid of Mold?

Whatever method you use to get rid, be it physical cleaning or ultraviolet light mold removal, the main problem is the spores. When you pick up an infected carpet, the spores fly up into the air and go searching for new surfaces to settle on. The only way to make your fight with the mold effective is to use air purifiers to suck up the spores. It’s especially important to have an air purifier working when you are physically removing the pieces of mold. Otherwise, your work may be absolutely futile.

I’ve been battling it in my home for many years due to the high humidity. Until I purchased an air purifier, I was losing the fight. Many people don’t realize that mold is not just what they see on their walls or floors. The main enemy is in the air and it’s absolutely invisible.

While looking for an efficient way to fight it, I’ve heard about UV light. It seems like an easy way to blast spores out of existence. But does black light kill mold completely? Unfortunately not. In order for the black light to work, the UV ray must be very close to the spore. Spores that fly far away from the light stay alive. Sometimes black light might kill up to 90 % of the spores in the air. 90 % seems a lot, doesn’t it? When it comes to the spores, anything less than 100 % is too little. If you allow even a few spores to live, you’ll have new mold forming at the speed of light.

When you are physically removing it from a surface, don’t forget to spray a disinfectant before touching it. This will reduce the number of spores that fly up into the air once the mold is disturbed. But in order to make sure that all the spores are gone, you need to purchase an air purifier with an HEPA-type filter.

Please note that if you have a big problem, you might not be able to deal with it on your own. You have to hire professional help to get rid of all the mold in your home. While the professionals are doing their job, make sure you have the air purifier working and eliminating all the spores from the air.

How to Choose the Best Air Purifier for Mold?

As I mentioned earlier, the spores are about 1- 100 microns in size. This means you have to buy an air purifier that can battle such small particles. The top rated air purifiers for getting rid of mold are those that feature HEPA filters. These filters take care of 99.97% of particles 0.3 microns in size. This means they can easily deal with the problem. In order to keep the air clean, you have to make sure to change the filters on a regular basis.

Spores that fly through the air are invisible to the eye. However, the musty smell sometimes produced by it can be obvious and unpleasant. In order to combat such odors, you need to look for an air purifier with an activated carbon filter. These filters absorb the odors and make the air fresher and easier to breathe.

Another important air purifier feature that can fight the mold spores is a negative ionizer. An ionizer releases negative ions that stick to the mold particles and allow them to be easily caught by the rest of the filters. Some people are not big fans of ionizers since they believe they produce ozone. This is not true anymore. Modern ionizers are not harmful to humans while they can effectively tackle the problem.

An ultraviolet lamp option in an air purifier is rare, but it can be a nice addition to the rest of your killing artillery. While it won’t get rid of the problem on its own, it can give a nice hand to the filers and the ionizer.

An ideal air purifier for mold should have an activated carbon filter, a HEPA filter, an ionizer and a UV lamp. Generally, a carbon filter and a HEPA filter are enough while the ionizer and a UV lamp are just nice additions that can help you in your fight.

The below three air purifiers have the necessary features to help. I checked each one closely to make sure it is a good option for any household or office.

Winix 5300-2 Air Purifier

I like this air purifier for its 4-stage filtration system that includes a pre-filter, an activated carbon filter, a HEPA filter, and an ionizer. While it can only cover the area of under 360 square feet, it’s a great fighter for average sized rooms.

While the IQ Air HealthPro Plus doesn’t have an ionizer as the other two air purifiers do, I’ve decided to name it the best air purifier for mold in 2019, due to its heavy-duty filtration system.

Even though this air purifier is more expensive than the other options, it can service more than twice the area while offering a powerful protection.
