How Mold Exposure Can Affect Your Health

According to the Centers for Disease Control and Prevention, not everyone has a sensitivity to mold and mildew, but for those that do, the common symptoms include a stuffy nose, irritated throat, coughing, and wheezing.

However, just because you don’t have an allergic reaction to mold doesn’t mean that it’s not causing harm to your health.

In fact, being exposed to mold over a long period of time has caused many people to develop a strong allergy to it.

In 2004, the Institute of Medicine discovered that exposure to indoor mold caused upper respiratory tract problems, coughing, and wheezing in otherwise healthy people.

Additionally, there have been other studies that suggest a link between early mold exposure and the development of asthma in children.

Having a mold allergy is kind of like a double-edged sword. Yes, it causes a whole host of health problems, but it also makes a person more aware of its presence and can therefore quickly spot when it’s becoming a serious problem.

The U.S. Department of Health states that indoor mold and mildew produce potent toxins that not only can be absorbed by the lungs but also the skin and intestines. The long-term effects of mold exposure can have serious effects on your health, including cancer, neurotoxicity, memory loss, cardiac conditions, and more.

Why Does Mold Become Such a Problem?

The reason why mold becomes such a big problem so fast is because it reproduces by forming millions of spores. These microscopic mold spores cannot be seen by the naked eye. And, what’s worse is that these spores are able to survive under conditions that visible mold cannot.

What this boils down to is that you may not see any physical evidence of mold or mildew in your home, but the spores are still present and have the potential of causing severe health problems and/or landing on a surface that is inhabitable that allows it to start growing again.

Another disturbing factor is that many types of mold form outside and can easily enter your home through open doors, windows and vents or hitchhike their way in on your clothing.

For these reasons, we highly suggest that you use an air purifier to control mold, mildew, and viruses. This simple device is able to remove all kinds of mold spores and viruses and is crucial to helping you live a healthy life.

Features to Look for in the Best Air Purifiers for Mold Spores

Now that you know the severity of the issue regarding mold, you may be wondering how do you find the best home air purifier for handling such an important task?

When looking for an air purifier for mold removal there are three key features you want to keep in mind.

Getting a device that has all of the options listed below will ensure that your home stays free of harmful mold spores and viruses.

  1. True HEPA Filter
    The first thing you want to make sure the room air purifier has is a True HEPA filter. This filter is essential because it is certified to capture particles as small as 0.3 microns. This includes all types of mold spores that make their way into your home. Getting a device that doesn’t have the True HEPA stamp doesn’t give you any guarantee that it will help with the problem. Stay away from air purifiers that say “HEPA-like” or “HEPA-type” as they’re inferior to a True HEPA device.
  2. Ultraviolet Light
    An Ultraviolet (UV) light is also crucial because it actually kills mold and viruses. It works by using a beam of light to zap the spores and virus pathogens to destroy their DNA makeup. The UV light is located inside the air purifier and no light is released into the room. It’s a great backup system for the True HEPA filter because it kills the particles that it cannot trap.
  3. Activated Carbon Filter
    This filter is also a must-have feature because it picks up where the other two types leave off—it eliminates mold odor. Activated carbon is excellent at trapping toxic Volatile Organic Compounds and Microbial Volatile Organic Compounds that mold and mildew emit. Without this feature, the smell of mold will still exist.

Buying an air cleaner that has a combination of these three features is your golden ticket to having a mold-free, virus-free, and odor-free home.

Best Air Purifier for Mold and Mildew SilverOnyx1. SilverOnyx 5-in-1 Air Purifier

If you want the best air purifier for mold and viruses at the most affordable price, this is it.

Best Air Purifier for Mold Spores GermGuardian AC5000E2. GermGuardian AC5000E Air Purifier

This is the next best air purifier for mold spores and is not very expensive.

It also includes the three essential filters mentioned above but the True HEPA filter is not cylindrical like our #1 recommendation. That doesn’t matter though because this air cleaner is made for small to medium sized rooms up to 200 square feet. A standard flat filter is perfectly fine for that size space.

The vertical shape is a nice design to have since it allows you to place the air purifier practically anywhere.

This device is also quite stylish compared to many other air purifiers on the market and looks great with any decor.

PureZone Best Air Purifier for Mold and Viruses3. Pure Enrichment PureZone Air Purifier

If you liked the idea of our #2 review, you may want to consider this one as well.

It includes all of the same air purification features as the GermGuardian AC5000E air purifier (True HEPA filter, UV Light, and Activated Carbon filter), but has a different shape and color.

Either model is a good choice for tackling mold and viruses in rooms up to 200 square feet, but you may just prefer the look (or size) of this air purifier over the previous option.

The choice is obviously yours, but either way, you’re getting the best air purifier for mold spores, viruses and bacteria at a low price.

GermGuardian AC5900W Air Purifier for Mold and Viruses4. GermGuardian AC5900W Air Purifier

This air purifier is a step up from our previous two reviews.

While the shape and color are a bit different than the GermGuardian AC5000E, it still has everything you need to control mold spores and viruses in your home.

The larger size of the True HEPA filter, Activated Carbon filter, and UV Light are suitable to clean the air in a 338 square foot room. That puts the power of this machine right in the middle of our #1 and #2 reviews.

If you have a medium to large size room to purify, this would be a better option for you.

Our final recommendation for the best air purifier for mold and viruses is this unit right here.

If you’re considering our #4 pick, then you may want to look into this air purifier before making your final decision.

What makes it a top contender are these additional user-friendly features:

  • Like our #1 choice, this model also includes a negative ion generator (ionizer) to boost the air cleaning power.

As for room size coverage, this air purifier can reduce mold, mildew, and viruses in a room up to 375 square feet—about the same as the GermGuardian AC5900W.

Additional Information on Mold and Air Purifiers

Other Benefits The Best Air Purifier for Mold Spores Can Give You

While you most likely came to this page because you were looking for an air purifier to get rid of a mold problem, there are some additional advantages you’ll enjoy by owning one of these devices.

As we noted above, the True HEPA filter captures the tiniest particles possible from the air. Not only does this mean that you’ll trap mold spores, but it will also help to get rid of other airborne particulates that cause health and/or breathing problems. This includes things like dust, pollen, and common allergens.

The Ultraviolet (UV) light will also take care of airborne viruses and bacteria that may be present inside the home or area you place the air purifier in. This will help sterilize the environment and keep it free from toxins that tend to make a person sick.

An added advantage of the Activated Carbon Filter is that it too eliminates more than just the odor produced by mold and mildew. As air is sucked in and passes through this filter, it will trap particulates that are the root cause of other smells inside your home. Common odors you’ll find reduced by the devices listed above include those from pets, cleaning supplies, cooking and some types of smoke.

An Air Purifier for Mold is a Great Investment

Often, once a person realizes that these mold air purifiers are also capable of tackling other indoor air quality issues, they move the device into a more centralized location or specific room that is in need of purification after the mold or mildew problem is taken care of.

As with all air purification devices, the end goal is to produce a clean, fresh environment that’s healthy for you to breathe. Yes, mold is a common problem in many homes, but so are these other things mentioned above too.

Being able to purify the air from other contaminants is an added benefit you’ll get from these products.

Information on Other Air Purification Technologies

These days, air purifiers come with a variety of features and rarely ever include just one type of air purification technology.

Therefore, it’s good for you to know what some of these other popular technologies do so you can ensure you’re getting the best air purifier that removes mold.

  • Ionizers – Some air purifiers are solely ionizers while others include this as an added function. What an ionizer does is sends out negatively charged ions into the air to latch onto positively charged particles like mold. These new clumps become too heavy to remain in the air and fall to the ground. While the mold spores are technically out of the air you breathe, they do still exist on the floor and surrounding surfaces which is what you want to avoid. An ionizer does nothing to destroy mold spores, it just removes them from the air faster.
  • PECO – This stands for Photo Electrochemical Oxidation and produces a reaction that takes place on the surface of a nano-coated filter which leads to the oxidation of organic matter such as mold. The advantage of PECO over a True HEPA filter is that it can destroy particulate matter as small as 0.1 nanometers. HEPA filters can only capture mold spores, not kill them. The only issue with PECO is that it’s a patented technology in Molekule air purifiers. So, you’ll have to invest in that brand if you want to have PECO air purification and their devices are quite expensive (around $799).
  • PCO – This stands for Photocatalytic Oxidation and is the more widespread variation of PECO. The difference is that it uses a combination of Ultraviolet light and a Titanium Oxide in the form of a TiO2-coated filter. The downside to PCO is that it produces trace amounts of ozone (0.01 – 0.04 ppm range) which may concern you. However, keep in mind that 0.05 ppm is the maximum level allowed by federal law for medical devices.

Best Air Purifier for Mold and Viruses Technology Recap

Now that you know what other air purification technologies are found in air purifiers, here’s a quick recap of the features you do want to look for:

  • True HEPA Filter – This captures the microscopic mold spores that are floating in the air.
  • Ultraviolet Light – This is what kills mold and viruses as they pass through the air purifier and prevents them from multiplying.
  • Activated Carbon Filter – This reduces mold odors and mildew odors, which no other filter can do.

The Most Common Indoor Areas for Mold Growth

There are many areas of the home that mold and mildew can grow undetected. Below are the most common locations.

  • Behind or below refrigerators
  • Below kitchen and bathroom sinks
  • Inside toilets
  • Inside basements or cellars that don’t have proper ventilation
  • Behind and around leaky windows
  • Behind drywall in where plumbing lines are located
  • Behind drywall that has been affected by flooding
  • Inside ventilation ducts
  • Under carpeting that was extremely damp or wet at one time (i.e. carpet cleaning or flooding)
  • Beneath stacks of newspapers and cardboard

How to Test the Air for Mold

While air purifiers are excellent devices for removing mold spores from indoor air, you may want to find out just how much mold is in the air you breathe.

To do that, you can easily purchase a home mold testing kit.

The most common versions of these kits include a glass petri dish that you leave exposed to the air for about 48 hours. Other kits actually include an air sample pump for collecting a measurable quantity of air to test for mold.

With petri dish kits, you let the dish sit for a few days to see if there are any signs of mold growth inside the dish. If there is, then you likey have mold in the air.

With an air pump kit, you take a sample of air and must send it into an AIHA Accredited laboratory to get the results. This includes additional fees.

Something to keep in mind regarding mold testing kits is that the U.S. Environmental Protection Agency (EPA) doesn’t recommend or support any kind of do-it-yourself mold test kit. The EPA states that sampling for mold should always be conducted by professionals who are trained in sampling protocols and interpretation.

Simple Tips for Preventing Mold

If you want to eliminate mold spores from the air you breathe, an air purifier is a good first step. However, there are some additional things you can do to stop or minimize the existence of mold.

These include:

  • Ensure that each room of your home is well ventilated. Mold and mildew need moisture to survive and rooms that have a high level of humidity usually have the worst problems with mold growth.
  • Keep your house cool. Most types of mold need a temperature of 70 degrees Fahrenheit (20 degrees Celsius) or higher for mold to thrive. Use air conditioners to regulate the temperature inside your entire home or target a specific room to prevent mold and mildew from growing.
  • Use a dehumidifier in areas where dampness is an issue. Places like basements are notorious for having moisture issues. If that’s the case inside your house, use a dehumidifier to lower the moisture content level. This can offset the conditions that mold likes to grow in.
  • Keep all surfaces dry. This includes walls, floors, and ceilings.
  • Routinely clean bathrooms and kitchens. These areas are the most likely places for mold and mildew to start. So, do a deep cleaning in and around sinks, toilets, bathtubs, refrigerators and other areas that stay damp or dark.
  • Routinely inspect windows. Leaky windows are a common place for mold to start growing. Take a look at each window of your home to ensure that a water leak hasn’t started or mold is not already multiplying in that area.

Common Questions About Mold and Air Purifiers

Do air purifiers help with mold?

Yes, an air purifier can help with mold. Air purifiers extract mold spores from the air so that the mold cannot multiply. The bare minimum filer an air purifier for mold must have is a True HEPA filter. It captures 99.97% of particles down to 0.3 microns. Two other important features are an Activated Carbon filter for reducing mold and mildew odors and an Ultraviolet Light to kill the active mold spores.

What is the best air purifier for mold spores?

The best air purifiers for mold spores are the following products that were reviewed above.

Each air purifier includes the top features for removing and destroying mold spores.

  1. SilverOnyx 5-in-1 Air Purifier
  2. GermGuardian AC5000E Air Purifier
  3. Pure Enrichment PureZone Air Purifier
  4. GermGuardian AC5900W Air Purifier
  5. InvisiClean Claro Air Purifier

Can mold dry out and die?

Yes, mold can dry out and die. Mold spores need moisture to grow and multiply. If you can reduce the moisture level, then the mold can become inactive. However, any existing mold growth you have will stay where it is. It does not dry up and go away on its own.

What happens if you breathe in mold spores?

If you breathe in mold spores two things can happen: 1) nothing, and 2) an allergic reaction. Breathing in low quantities of mold often goes unnoticed by most people. But, if you have a mold allergy then even the smallest trace of breathing in mold can cause an allergic reaction. Breathing in large quantities of mold will cause a reaction in everyone, no matter if you have a mold allergy or not.

When mold is breathed in your immune system can overreact which will make you cough, wheeze, sneeze, have a runny nose, postnasal drip, and feel tightness in the chest. Long-term exposure to mold can cause upper respiratory infections, nausea, headaches, vomiting, fatigue, memory loss, and pulmonary hemorrhage.

Is it OK to sleep in a room with mold?

No, it is not safe to sleep in a bedroom with mold. Breathing in mold for 6-8 hours while you’re sleeping can cause a number of health problems. Beyond the immediate allergy symptoms, sleeping in a bedroom with active mold growth can cause long-term issues such as stomach pains, muscle cramps, anxiety, confusion, numbness in hands and feet, sensitivity to light, upper respiratory infections, etc.

That’s why it’s important to have one of the best air purifiers for mold in your bedroom if you suspect there is any presence of mold. The air purifier will actively work to remove mold from the air to keep you healthy while you sleep.
