What to Consider When Choosing the Best Air Purifier for Mold

Mold is a type of fungus that typically grows on any available organic matter, such as leather, carpet, drywall, wooden floors, paper, etc. You will likely deal with mold growth if you live in a warm, damp area with high humidity. And black mold is a type of mold that is common indoors, polluting the air via mold spores.

EnviroKlenz SVP George Negron states, “Mold growth has much to do with air quality in your home. Factors like airflow, ventilation, and humidity can easily determine whether a space in your home is suitable for mold growth. Not to mention, mold spores travel through the air before attaching to an optimal surface.”

The more mold you have in your home, the more likely they trigger your immune system, causing allergic reactions. Some health issues that mold allergies cause include asthma attacks, shortness of breath, skin irritation, a runny nose, etc.

So, once you experience such symptoms and detect a musty smell, it’s time to find the right type of air purifier to deal with mold spores. Below are the factors you can consider to find the best air purifier for mold and dust mites.

Coverage Area

When dealing with indoor air pollution, you need to consider the size of the room. For that reason, you must measure the length and width of your space and obtain the area.

Smaller rooms require a lower capacity air cleaner than bigger ones. But, on the other hand, if you choose a lower-capacity purifier for a large space, it won’t eliminate all the mold spores in the air, leaving you vulnerable.

Usually, air purifiers are rated based on the square footage they cover and the number of air exchanges within one hour. For example, the best HEPA air purifier for mold will provide about four air exchanges per hour. So, it would be best to look for terms such as “X square feet every 30 minutes,” etc. The larger the value, the more capable the device can purify the air.

Typically, those that cover under 300 square feet are small, between 300 and 699 square feet are medium, and between 700 and 1,000 square feet are large.

Clean Air Delivery Rate (CADR)

CADR helps determine how effective an air purifier is based on the volume of clean air it produces per minute relative to the room size. And it is usually measured at the highest fan speed and determined based on tests done by the Association of Home Appliance Manufacturers (AHAM).

The Environmental Protection Agency and the US Food and Drug Administration both endorse CADR, expressed as cubic feet per minute (CFM) or cubic meters per min (m³/min). And the higher the CFM value, the higher the device’s performance capability.

Moe Bedard of Mold Safe Solutions says, “When shopping for a HEPA air purifier, look for one with a high CADR rating. This rating indicates the amount of airflow the purifier can deliver and can be used to compare different models. Choose a model rated for your specific needs – for example, if you’re looking for an air purifier for a large room, choose one with a high CADR rating.”

Ideally, an air purifier should have at least 150 CFM. But the best air purifier for mold may produce 350 CFM or more.

Filtration Mechanism

Because mold, viruses, and bacteria are a particular size, you need to consider the filtration system within the air purifier and its effectiveness. And there are several that are worth checking.

First, you should look for high-efficiency particulate air (HEPA) filters. These filters have a design that eliminates at least 99.97% harmful airborne particles with a size of 0.3 microns, including bacterial mold and pollen. But some HEPA air purifiers are more effective and can eliminate smaller particles.

Tim Swackahmmer, CEO of Mold Medics, says, “HEPA filtration is a must. HEPA or High-Efficiency Particulate Air filters are rated to remove 99.97% of airborne particles over .3 microns in size. This results in excellent filtration of mold, bacteria, dust, pollen, and other allergens.”

Second, you should consider whether the mold air purifiers use UV-C light. Research shows that UV-C light may kill some types of molds, bacteria, and viruses, disinfecting your home. For that reason, having a device that produces it may enhance the purity of your air.

An activated carbon layer is also worth having in any filtration system. It uses the process of adsorption to trap harmful gas molecules and remove them from the air. If your space has musty odors or foul smells, such a filter comes in handy.

It is worth noting that filters don’t work into perpetuity. So, it would be best to think about the lifespan of an air purifier’s filtration system. Some can be removed, cleaned, and reused, extending their life. Generally, the longer the air cleaner filters last, the lower their replacement costs will be.

Sarah Lavine with EnviroHome states, “HEPA filters should be replaced regularly to work efficiently and provide the correct level of filtration. It is not enough to have a HEPA filter, you must maintain it as well.”

Noise levels

Many air purifiers have fans, which help to move the air in circulation. Unfortunately, such components tend to be noisy while working. And that could be an issue if you prefer devices with silent operations.

On average, standard air purifiers produce about 30 to 70DB. The higher the noise levels, the more bothersome it will be when you need peace. However, if an air cleaner has several fan speed settings, you can adjust its air purification speed and noise levels, depending on your air quality and concentration needs.

Product Quality

Air purifiers with CARB, ETL, and Energy Star certifications provide additional assurance concerning quality. Such marks mean the products have passed the strict safety and energy efficiency requirements. Therefore, choosing the best air purifier for mold will give you excellent value.

Portability

If you intend to move your air purifier from one room to another, depending on where you are at any given point, then think about its portability. You should be able to easily lift or move the appliance in question with minimal hassles. Otherwise, it would be inconvenient to use it.

Some air purifiers are as light as eight pounds, while others weigh more than 20 pounds. Usually, higher-capacity devices tend to be heavier. Select one that balances performance and portability for the best results.

Usability

In the era of technology, many air purifiers offer smart features to enhance ease of use. And these features will help to improve your convenience.

For example, some devices have auto modes that detect air quality and adjust fan speeds accordingly. Others have remote-controlled sensors that allow you to make air purification adjustments from a distance.

Other attractive features include LED panels that enable you to control settings from one point, child lock mechanisms to prevent interference from pets and children and filter replacement indicators.

HEPA Filter vs Ionizer vs UV Light

A HEPA filter is a filter that traps at least 99.97% of pollutants in the air as small as 0.3 microns. UV light is a form of electromagnetic radiation with a medium wavelength that kills organic matter, such as viruses, bacteria, and some types of molds.

And an ionizer is a device that charges the air particles and causes them to clump and stick to a designated surface to improve air quality. However, it works best on small but not big particles, such as tobacco smoke. Also, it is ineffective against odors and gases.
