Best Air Purifier For Mold How To Make Your Indoor Space A Healthy One

An air purifier can transform an unhealthy space into a healthy one. Mold poses the greatest health threat as it is ubiquitous but invisible. When mold issues escalate, they contribute to sick building syndrome.

Eliminating a mold source is not difficult, nor is cleaning the air in your home. Choosing the best air purifier for mold is a step in the right direction to improve indoor air quality in your living and working spaces.

What is Mold And Why Is It in My Home?

Mold, the same fungi found in your refrigerator, can also grow inside your home. It is a type of fungus with thousands of different varieties that can grow outdoors and indoors, according to Medical News Today.

The first thing to check is your home’s humidity levels. Mold produces and releases spores into the air, where they spread and grow. Air purifiers eliminate mold spores by attacking them before they settle inside your home.

The spores, though unseen, are everywhere and can easily enter your home along with other pollutants. Mold can enter through windows, doors, ventilation systems, or even on your pet and clothes.

Mold growth is most prevalent during fall and winter when windows are closed, creating ideal conditions for mold to thrive.

If there is mold present, it can be seen and smelled. Mold grows behind drywall where there are plumbing lines or in areas that have experienced flooding.

Choosing the Best Air Purifier For Mold

Best Air Purifier For Mold How To Make Your Indoor Space A Healthy One

When looking for a new air purifier, there are a few key things to consider:

– True HEPA Filter: Look for an air purifier with a true HEPA filter. HEPA stands for High-Efficiency Particulate Air and can remove 99.97% of particles from the air down to 0.3 microns in diameter, including mold spores.

– Washable or HEPA Filter: Make sure the air purifier has a washable or HEPA filter. This will save you from having to replace the filter every two weeks.

– Energy Star Certified: Choose an air purifier that is Energy Star certified for cost and sustainability reasons. While there are other certifications available, the Energy Star rating is the main one to consider.

The Association of Home Appliance Manufacturers (AHAM) certifies air purifiers based on their clean air delivery rate (CADR) and room size guidelines. While specific CADR figures exist for pollutants like smoke, pollen, and dust, mold does not have a specific rating. Studies have shown that portable UV-C light air purifiers only provide limited protection against mold and cannot address VOCs and other airborne particles. Here are the top air purifiers for mold:

1. LEVOIT Air Purifier

The Basics of Mold

As noted, there are thousands of types of mold, but not all are harmful. Some types, like those used to make blue cheese or penicillin, are actually beneficial. However, certain molds, such as black mold, have been shown or suspected to release harmful substances along with their spores.

According to the US Centers for Disease Control, if you can see mold or smell its musty odor, you should remove it and address the underlying cause in your home.

Identifying the specific type of mold is not necessary, and you don’t need to spend money on testing. Regardless of the type, all mold problems should be addressed.

Allergenic mold may not make you sick, but it can worsen allergies.

Pathogenic mold can cause infections, especially in people with weakened immune systems.

Mold can cause illness in people with compromised immune systems. It is also toxic to animals, including pets. The most concerning category of mold is toxigenic mold, which releases mycotoxins that can become airborne with the spores.

Some studies have shown that these chemicals can also attach to other particles, such as dust, and spread through the air. One example of toxigenic mold is black mold.

This is the infamous black mold, believed to pose the greatest danger at home. Known as Stachybotrys chartarum, it thrives on cellulose-based materials like wood, paper, fiberboard, and drywall. It can be found in warm and damp areas, including inside walls and under carpets or flooring.

According to the CDC, Stachybotrys chartarum, along with other molds, can cause nonspecific health symptoms. Thus, the type of mold is irrelevant – all molds must be removed.

Mold’s Health Effects

According to the National Capital Poison Control Center, numerous studies have been conducted on allergies and mold, yielding various conclusions. It can be difficult to link specific types of mold to respiratory effects and other irritants such as second-hand smoke, airborne particles, and volatile organic compounds.

Experts generally agree that spending time in damp and moldy environments increases the risk of bronchitis and respiratory infections, although this has not been definitively proven.

To eradicate mold from your home, it is crucial to prevent moisture accumulation. A proactive approach is vital.

– promptly address any leaks and thoroughly dry or replace any affected materials.

Keep your home’s humidity at around 40 percent.

To clean mold from a hard surface, use soap and water, a commercial cleaning product, or a bleach solution of 1 cup (8 ounces) of bleach in 1 gallon of water.

Keep damp areas of the home well-ventilated, including kitchens, bathrooms, and laundry rooms.

Consider using floor coverings other than carpet in areas that are often damp.

If the mold growth is extensive or difficult to reach, call a professional mold-cleaning service.

To determine if there are airborne mold spores in your home, start with a simple mold test kit available online or in a home improvement store.

Make sure to obtain a mold test kit, which takes a few days to determine if there are spores in the air. Some kits also allow you to send the test to professionals for mold identification.

How does mold affect my health?

While certain toxic molds, like black mold (Stachybotrys chartarum), contain high levels of dangerous mycotoxins, any mold that is not removed can grow and cause health problems.

The US Centers for Disease Control (CDC) states that some people are more sensitive to molds than others. Mold exposure can cause symptoms such as a stuffy nose, wheezing, and red or itchy eyes or skin. Severe reactions to high mold concentrations can include fever and shortness of breath.

Anyone with asthma, allergies, or suppressed immune systems can be more susceptible to mold. Studies have shown that even healthy people can develop respiratory symptoms from mold exposure. Mold has also been linked to asthma development in children.

To prevent mold from becoming a problem, it’s important to eliminate the source of the mold. Additionally, reducing humidity to levels below 60 percent is recommended by the Environmental Protection Agency. Good ventilation is also an excellent preventive measure.

In the meantime, the next important step is to filter indoor air and remove pollutants like mold spores.

Frequently Asked Questions (FAQ)

What Air Purifier Do I Need For Mold?

When you have mold in your home, an air purifier will remove airborne particles and prevent mold spores from developing.

An air purifier with an activated carbon filter attacks mold before it can grow inside your home. The filtration system removes toxins from the air caused by air conditioners or upholstered furniture.

You want to buy an air purifier that uses a High-Efficiency Particulate Air (HEPA) filter. The filter has a glass mesh capable of removing 99.97 percent of particles from the air down to 0.3 microns in diameter. This includes mold spores, which usually range from one to 30 microns.

Not all air purifiers have a HEPA filter, but most do.

The most effective location for an air purifier is where the mold is present or where there is excessive dampness. Additional purifiers can be placed in bedrooms for cleaner indoor air.

Each air purifier is designed for a specific room size. To maximize protection, choose a purifier that can handle your square footage.

An air purifier designed for up to 300 square feet can be placed in a 200 square foot room, but not the other way around. This is because it won’t be as effective in cleaning the air.

When choosing an air purifier for mold, look for one with an Energy Star rating for electricity cost and sustainability. However, there is no mold-specific certification for air purifiers. AHAM (the Association of Home Appliance Manufacturers) offers a voluntary certification program that provides the clean air delivery rate (CADR), but there is no CADR rating for mold.

CADR stands for “clean air delivery rate,” which measures the number of specific particles an air purifier can remove from the air. A higher CADR rating indicates a faster elimination of mold from a room’s air. The duration of running an air purifier varies, but it is advisable to have it on while in the room. For bedrooms, it should be left on overnight with the option of a silent or inaudible nighttime setting.

As for filter changes, frequency will depend on usage.

Every air purifier is unique, and the manufacturer’s guidebook will indicate when the filter needs to be changed. Most HEPA filters last 12 to 18 months, and many air purifiers today have an indicator to alert you when it’s time for a replacement.

Some air purifiers have a prefilter to capture larger particles, while others do not. The filters should be cleaned every 30 days and replaced if they are worn out. Carbon filters, if present, need to be replaced every three to six months.

Aside from maintaining the filters, an air purifier requires no other maintenance.

In conclusion, an air purifier for mold is an essential device that improves indoor air quality by effectively removing mold spores.

Air purifiers improve indoor air quality in homes and offices. To prevent and treat mold growth, it’s important to use the best air purifier available. Luckily, affordable options are readily available.

These energy-efficient devices effectively eliminate mold by utilizing UV lamps and carbon filters. Air purifiers are especially beneficial for large rooms. By capturing and removing microscopic airborne particles, they act as a germ guardian against mold.

If you have mold spores and want to remove them, search for “home mold spore removal” on Google for instructions. However, the goal is to prevent mold growth so spores won’t develop in your living room. One solution is to use a smart air purifier that targets mold.

Protecting the air quality in your home protects your family and home’s structure. With the best air purifier, you can sleep well knowing there won’t be mold in your home.
