How Do We Measure?
Not every air cleaner is capable of removing mold. There are few things you need to consider before getting one. Features like the coverage size, the types of filtration, noise level, and power efficiency can determine how usable it is the device. To give you a clear picture of your needs, here's our buying guide for the best air purifiers for mold.
- Room size/ Coverage - Never underestimate the speed of mold infestation. Mold can spread around the house within 24 to 48 hours and slowly colonize your home space one inch per day. An air purifier with strong airflow can easily cover an entire room from allergens intrusion. The wider the purifying coverage, the bigger the room size it can support.
- CADR - A measurement by AHAM that calculates the room size an air purifier can support. Clean air delivery rate measures the amount of air filtered by an air purifier in cubic feet per minute. 3 separate tests are conducted on dust, pollen, and smoke to give a more accurate rating. 200 cfm is a good benchmark for most bedrooms and small living halls. The higher the CADR, the faster the air can be clean.
- HEPA filter - The must-have filtration in a mold air purifier. A high-efficiency particulate air (HEPA) filter has the capacity to get rid of mold and other microscopic allergens. Only consider a True HEPA filter that is certified on its efficiency by the U.S. Department of Energy (DOE) instead of a HEPA-type filter.
- Activated carbon filter - Another must-have filtration that focuses on removing gas and musty odor through chemical adsorption. Compliments well on a HEPA filter. Look for a dedicated carbon filter with a high porous surface area so more smoke particles can be absorbed in one go. Avoid models that come with a less effective thin carbon sheet or 2-in-1 carbon pre-filter.
- UV-C/ UVGI/ PCO/ PECO - Uses the shortwave length of ultraviolet light to disinfect mold, bacteria, and viruses. Great as a supportive filtration that halts captured microorganisms from further growth and spread. As a standalone, UV-C light is not effective against large PM10 particulates and its efficiency will degrade with the light intensity drops. Some mold strains are also known to be resistant to UV radiation thus it will take a longer time to kill.
- Ionization - A safe purification technology that releases negative ions to bring down airborne pollutants. The fallen pollutants will still be scattered in the room unless it is vacuum away or captures by the filter. That's why you should only consider a HEPA air purifier with an ionizer feature rather than a standalone ionic air purifier.
- Dimension - For those that stay in a tiny apartment or small bedroom, look for a more portable, compact air purifier that will not eat up our entire interior space. If space is no issue, pick a large air purifier that holds a bigger fan motor and filtration with stronger airflow performance.
- Noise level - Highly dependant on the current fan speed it is running. If you intend to use an air purifier during work or sleep, avoid models that output higher than 60 decibels similar to an air conditioner. For low-speed operation, a whispering 20-30 decibels would be the ideal level of noise. Remember, the more silent is an air purifier, the more usable it will be.
- Pricing - Mold air purifiers can range from 150 to 900 dollars based on the size, category, airflow speed, and cost of ownership. Set a budget that you are comfortable with including the recurring disposable filter cost that you will have to bear annually. Pricing should not be the sole factor in determining the best mold air purifier.
- Additional features - From the remote control, auto mode, sleep mode, air quality indicator, caster wheels, timer, Wi-Fi, to Bluetooth connectivity. Anything that can help with the usability of an air purifier would be welcome with open arms.
1. Blueair 605 Air Purifier
- Traps mold and particulates down to 0.1 microns.
- Outstanding CADR and coverage.
- DualProtection filters (Particle + SmokeStop).
- Patented HEPAsilent technology.
- Galvanized steel body.
- Wi-Fi connects.
- Very expensive.
- Big and bulky.
- Addon for Blueair Aware monitor.
- High annual filter cost.
Any of the Blueair air purifiers would fit into our best air purifier for mold spores list. We pick Blueair 605 because it is the most powerful in its Classic lineup. At 20 x 26 x 13 inches in dimension, this is not the air purifier to go with if you have limited spaces in a room. Adding the 35 pounds premium galvanized steel body, moving around Blueair 605 can be tricky despite the included caster wheels. Build quality is great and the fitting is tight. The extensive 5 years warranty is the perfect icing on the cake. Mold, spores, and other allergens trapped inside will have no chance of sneaking out.
One of the best mold-removing air purifiers that can trap even the smallest microorganisms. However, the HEPASilent technology can be expensive to own and maintain thus it is not for everyone.
Moving to the controls, Blueair 605 simple operation heavily relies on the LED display. You can cycle between the 3 fan speeds, reset the filter replacement indicator after changing the filters, and turn on Wi-Fi support. Blueair 605 supports remote access via the Blueair Friend app available for download in iOS and Google Play. It comes with advanced features such as brightness intensity, night mode, child lock, timer scheduling, and real-time air quality data with saved logs. Everything can be done at the comfort of your couch.
Looking inside Blueair 605 air purifier specification:
- CADR - 640 cfm
- Room Coverage - 775 sq. ft.
- Fan Speed - 3
- Air Filtration - HEPASilent Technology, Particle Filter, SmokeStop Filter
- Warranty - 5 years
Blueair Classic 605 airflow delivery rate is from 150 cfm all the way up to 650 cfm at max speed. Even running at the lowest speed, airflow is plentiful and consistent. With up to 5 air changes an hour, it can cover a high 775 square footage of enclosed space. Ideal for large room sizes like living hall, dining room, lounge, basement, bedroom, or kitchen. CADR is highly impressive at 500 cfm for dust, 640 cfm for pollen, and 500 cfm for smoke. If you need to quickly remove mold, mildew, pollen, and other allergens in the air, Blueair 605 will not disappoint you.
HEPASilent Technology is the ultimate combination of electrostatic and mechanical filtration. The filters are ultrasonically bonded with natural antibacterial polypropylene fibers to prevent mold growth. It begins with the encapsulated particle-charging chamber electrostatically charging incoming pollutants to be more adhere to the particle filter. The sticky pollutants will be more sticky to the particles filter that boosts a 99.97% efficiency as small as 0.1 microns in size. The SmokeStop Carbon filter will absorb gas particles and ozone via chemical adsorption resulting a cleaner, fresher air.
Being a heavy-duty unit, Blueair 605 noise output is on the higher side between 32 dB(A) to 62 dB(A). You can still use it in the bedroom as long as you keep the fan speed low. The power consumption is acceptable hovering around 15 watts to 100 watts depending on the fan speed. Blueair 605 is Energy Star certified after all.
A powerful mold removal air purifier that will cost you an arm and a leg. Blueair 605 does have its fair share of downsides. It is gigantic and heavy compared to most of the air purifiers for mold. Despite the premium price you're paying, there's no air quality sensor and auto mode by default. The high annual filter replacement cost is also a recurring theme that you need to be aware of. So depending on how much air purifying is needed and how serious is your mold allergies, you could opt for the smaller Blueair 480i that reap the same benefits but at a much lower price.
In short: One of the best mold-removing air purifiers that can trap even the smallest microorganisms. However, the HEPASilent technology can be expensive to own and maintain thus it is not for everyone.

2. Rabbit Air MinusA2 SPA-780A Air Purifier
- 6-stage filtration against mold.
- Pre-filter + medium filter.
- True HEPA filter.
- Activated carbon filter.
- Negative Ion Generator.
- Trio sensor, auto/ sleep mode, timer, remote control.
- Average airflow output.
- Extra cost on the customizable filter.
Do not be fool by Rabbit MinusA2 SPA-780A so-called “average” pollen CADR output. This is the ultimate 6-stage mold eliminator you can get your hands to. It has excellent purifying coverage ideal for any room size such as living room, bedroom, basement, garage. The boxy dimension of 21.4 inches width, 20 inches height, and 7 inches depth will not take up much room space as it can be mountable to the wall like a frame. The only thing is you can't move it around for room to room purifying since it is hanging on the wall. Build quality and fitting is top-notch as evidence by the thousands of positive reviews and long 5-year warranty from the brand itself.
The only premium wall-mounted air purifier here that can deal with airborne mold and mildew allergens. For an even better filtration against microbes, consider one of the 4 customizable filters upgrade.
There's plenty of ways you can enhance Rabbit MinusA2 air purifier usability. First, It is decorable where you can swap the front panel with many customizable designs (addon cost). Second, there is a relaxing mood lighting bar that changes from solid blue, purple to pink. Not to confuse with an air quality indicator that shifts color from blue, purple, to red when the room air quality drops. Standard operation includes 5 manually selectable fan speeds, auto mode, and sleep mode. Auto mode will only set the fan speed to high when it detects an increase in airborne pollutants. Sleep mode automatically locks the fan speed to low and dims all indicator lights when the room turns pitch black. The filter replacement indicator is also present to alert users to change the filter. The most important feature of all in Rabbit MinusA2 is the inclusion of remote control. Now you can make adjustments from a distance without having to reach out on the wall-mount control panel.
Looking inside Rabbit MinusA2 air purifier specification:
- CADR - 200 cfm
- Room Coverage - 815 sq. ft.
- Fan Speed - 5
- Air Filtration - Pre-filter, HEPA Filter, Activated Carbon Filter, Negative Ion Generator, Medium Filter, Customized Filter
- Warranty - 5 years
As the name suggested, this is the higher variant SPA-780A that cleans airborne mold in a room of up to 815 square footage at 2 air changes per hour. For a hypersensitive or asthmatic person that needs a persistent airflow, you can increase to 4 air changes per hour but the room size coverage will drop to 408 square footage. Rabbit Air MinusA2 airflow delivery rate is between 58 cubic feet per minute (cfm) to 218 cfm. Not the greatest but sufficient for a wall-mountable unit. CADR tally with the airflow output with dust at 193 cfm, pollen at 200 cfm, and smoke at 180 cfm.
No mold, mildew, and other biological pollutants will be able to bypass Rabbit Air 6-stage filtration. First, large irritants like dust, hair, pet dander, dust mite, and pollen will be captured either by the pre-filter or medium filter. For particulates that manage to bypass both the pre-filter and medium filter, you have the 99.97% efficiency HEPA filter standing by to trap particulates as small as 0.3 microns. For an even more in-depth removal, you can add 1 of the 4 customizable filters from Germ Defense Filter, Pet Allergy Filter, Toxin Absorber Filter, and Odor Remover Filter. Any smoke and musty odors that have not been deal with will be absorbed by the Activated Carbon filter. Last but certainly not least, an optional Negative Ion Generator will assist in pulling contaminants down for the multi-layered filter to capture.
Rabbit Air MinusA2 will run silently at 25.6 decibels to a max 51.3 decibels. You will not hear any noise when it is hanging up high on the wall. As an Energy Star certified model, MinusA2 will run efficiently from a standby mode of 7 watts to 61 watts. For better energy management, leave it in auto/ sleep mode and the air purifier will run autonomously by itself.
In spite of MinusA2 and compactness and nifty purification, there are a few notable drawbacks. First, the CADR and airflow delivery rate is under par compared with its purifying range. Regardless of which variant you go for, you will have to pay top dollar for this air purifier. All the addons like customizable front panels and extra filters are extra costs to incur. Finally, the total weight is rather hefty, but it will not be a problem as long as you mount it to a wall. After all, that is the whole purpose of getting a Rabbit Air MinusA2.
In short: The only premium wall-mounted air purifier here that can deal with airborne mold and mildew allergens. For an even better filtration against microbes, consider one of the 4 customizable filters upgrade.

3. IQAir HealthPro Plus Air Purifier
- The best air purifier in removing mold.
- Strong airflow for large room size.
- PreMax Filter.
- HyperHEPA Filter.
- V5-Cell Gas & Odor Filter.
- Advanced scheduler.
- Expensive to own and maintain.
- Bulky and heavy.
- No autonomous mode.
Many sites did not include IQAir HealthPro Plus in their "Best air purifier for mold list". Why? Because it is not a high selling volume due to its high price tag. Not us though as the strong airflow performance and filtration alone justified its inclusion. Top it off with a leading 6-speed mode and super-wide coverage, you can never go wrong with HealthPro Plus.
The best mold removal machine when money is no biggie. If you have the budget and can sustain its filter replacement cost, go right ahead.
IQAir iconic white body framework will take up a large chunk of your interior space. At a 15 inches width, 28 inches height, 16 inches depth, and 35.3 pounds weight, it is not the most manoeuver machine around even with the 4 durable caster wheels. The hefty weight is also contributed by the super durable ABS plastic housing and 3D UltraSeal triple-seal technology. Any pollutants that are trapped inside will not stand a chance of escaping. It is also the few machines that is officially certified by IAACM to be 100% ozone-free.
IQAir HealthPro Plus is very easy to use with distinctive buttons and a digital display. Besides making a quick adjustment to the 6 fan speeds, you can also depend on the programmable timer and set a day, speed, and time to shut down the machine. The Intelligent Filter Life Monitor will accurately measure the filter usage life and replace it when necessary. Last but not least, there is also a remote control bundled to ease the operation.
Looking inside IQAir HealthPro Plus air purifier specification:
- Pollen CADR - N/A
- Room Coverage - 1098 sq. ft.
- Fan Speed - 6
- Air Filtration - PreMax Filter F8, HyperHEPA Filter H12/13, V5-Cell Gas & Odor Filter MG
- Warranty - 3-10 years
There are two things IQAir does better than the rest: air cleaning and filtration. IQAir HealthPro Plus has 6 adjustable fan speeds that deliver from 41 cfm to a high 300 cfm of airflow delivery rate guaranteed. Following the impressive airflow performance is the wide 1098 square footage coverage. Highly suited for large room sizes with moldy problems due to poor ventilation and no sunlight like a two car garage, basement storage, lounge, and laundry room. IQAir HealthPro Plus can even cover an entire home or condo when you leave all doors open with no obstruction.
The core of IQAir HealthPro Plus lies with its filtration. When airborne pollutants are drawn inside the 360 air inlet, the PreMax Filter F8 will block initial particulates from passing through and end up clogging the HEPA filter. Next, the remarkable HyperHEPA filter will trap microscopic allergens as small as 0.003 microns including bacteria and viruses. The V5-Cell Granular activated Carbon filter with Pelletized chemisorption filter removes even the toughest chemical fumes, ozone, and odors that are detrimental to our health. You will definitely feel improvement in the air quality simply by leaving IQAir on for a couple of hours.
Noise level is very well contained thanks to the double-walled housing, sound deflector EvenFlow Diffuser, rubber suspension pad, and backward, curved centrifugal fan. Expect a low noise output between 25 to 59 dB depending on the fan speed. Energy usage is a bit of mixed bag as it can be under 27 watts to a max 215 watts per hour. There are other more energy saving units but non offered the same performance as IQAir HealthPro Plus.
There is no doubt on IQAir caliber in dealing with mold and other fungi. However, the close to 1000 pricing is the main reason many people will not opt for this model. Besides the hefty cost, the filter's sustainability is another setback as you will have to fork 100+ dollars year in, year out. The tall and bulky body is also very hard to maneuver despite the added caster wheels. Lastly, there is no autonomous mode or air quality indicator built-in, you will have to rely on the schedule for better energy management.
In short: The best mold removal machine when money is no biggie. If you have the budget and can sustain its filter replacement cost, go right ahead.

At the same time, it will reduce the dependence of the HEPA filter. The True HEPA filter capture 99.97% of particulates small as 0.3 microns.

It is an absolutely safe and proven technology that does not produce harmful byproducts.
There are a lot of things to like about Winix 5500-2, the rather expensive HEPA + carbon filter replacement cost is not one of them. Expect to pay an average of 80 dollars annually with 24 hours of daily operation. The VOC sensors will occasionally doze off in detecting air quality changes, but the delay is momentarily so don't worry too much about it. It will not hinder Auto mode from functioning properly.
In short: A dependable yet inexpensive 4-stage filtration air purifier that has plenty to offer. Adding Winix's awesome PlasmaWave technology, no mold and mildew will be able to get away from its sight.

Most Alen air purifiers would fit well in our best air purifier for mold list. We pick the OG Alen BreatheSmart air purifier as it is the classic variant effective in reducing mold patches in the home.

You even have the option to swap the front panel with many attractive colors and designs available online. Weight is around 21 pounds including filter, not the lightest but can be moved around with limited effort. The air quality indicator is not at the usual front spot, it does change from blue, yellow, or red to indicate the level of airborne pollutants in the room.
Alen BreatheSmart strikes a balance between price, performance, and overall dimension. With the right set of filters, you can enjoy the best of both worlds for a lifetime.
Operating Alen BreatheSmart is dead easy with all the controls nicely arranged. You can cycle through the 4 speeds or activate auto mode and let the air purifier decide what speed to run based on room air quality. A timer is available with 3 preset settings and so is the popular child lock. Also in the list is an optional ionizer that can be disabled when not needed. Lastly, an advanced Smart Filter calculates the remaining filter life so you will know when to replace it. Overall, we are happy with the features and build quality displayed. Note that the lifetime warranty is only available for those that registered on Alen's website with a filter subscription.
Looking inside Alen BreatheSmart air purifier specification:

Alen BreatheSmart CADR is averaging at 300 cfm for dust, pollen, and smoke with the default filter. The figures will not go too far off even if you opt for the upgraded filter set.
A superb mold removal machine with a little bit of quirk. By default, Alen BreatheSmart air purifier uses the standard HEPA-Pure bundled filter set. It comes with a washable pre-filter that traps large particles and prolongs the HEPA filter usage life. The highly dependable True-HEPA filter will capture tiny particles and pathogens that cannot be seen by our naked eyes. There is also a built-in ionizer that diffuses negative ions to charge positive ions contaminants in the air. The now heavier particles would fall allowing the HEPA filter to capture. Notice there is no smoke filtration here. For that, you will need to upgrade to the HEPA-Silver filter that specialized in capturing germs and smelly mold. A must-have in our book.
What's not so good about Alen BreatheSmart is the default HEPA-pure filter. It is the basic version that lacks odor filtration to deal with musty smells. You will need to top up for a better set which adds to the annual filter cost. Other than that, minor complaints like the loud noise, bright indicator, and dozy sensor are livable. Regardless of where you intend to use Alen BreatheSmart, it will have no impact on the air purifier's effectiveness against mold.
In short: Alen BreatheSmart strikes a balance between price, performance, and overall dimension. With the right set of filters, you can enjoy the best of both worlds for a lifetime.

Airmega 400 air purifier relies purely on a 4-stage mechanical filtration to clean the air. It is 100% ozone-free with no byproducts ever produced. Dirty air will first be pulled in through both sides of the air inlet. The outer pre-filter trap large particles like dust, hair, lint from passing through and shield the HEPA filter from getting clogged. The freed Green True HEPA filter will capture 99.97% of microscopic particles as small as 0.3 microns including mold, mildew, and pollen. The activated carbon filter focus on neutralizing smoke and musty odor created by the allergens.
Coway Airmega 300 complies with Energy Star requirement with 6 to 57 watts of power consumption per hour. Even at the highest speed, it is far more efficient than some of the mold air purifiers here. Noise level is on the quiet side with an output of 22 to 52 decibels. With the auto sleep mode feature enabled by default, you can enjoy a good night of sleep while having Airmega 300 running silently in the background.
Yet another expensive air purifier that is not meant for everyone. Airmega has a premium price tag to accommodate its long list of specifications. Thankfully there's plenty of good deals online to subsidize the price. As for maintenance, the MAX2 filter replacement will cost you around 100 dollars annually for both HEPA and carbon filters. It is required for the air purifier to function so that's something you need to ponder. Last but not least, the ionizer is surprisingly omitted here but that's not a big miss for most people.
In short: A wonderful mold removal air purifier that always comes with a great discount. If you're not into the ionizer, the mechanical HEPA filtration is more than sufficient to help curb your mold allergies.

Besides mechanical, there are also different types of air cleaners that you should be make aware of.
- HEPA air purifier - The safest and best option to clean the air. It mainly uses mechanical filtration i.e. a pre-filter, True HEPA filter, and an activated carbon filter to capture airborne particles.
- Ionizer - Generates negative ions that attract and merge with positive ion particles. The merged particles will fall from the increased weight, leaving the air cleaner to breathe.
- Electrostatic precipitator - Like an ionizer but comes with a collector plate that captures the charged particles, there is less need for vacuuming. Not available as part of a multi-filtration.
- UVGI/ PCO air purifier - Relies on UV-C radiation and/ or titanium dioxide that destroys the DNA of microorganisms. The sterilized allergens will be left dormant and incapable of reproduction.
- Ozone generator - Not recommended by EPA and CARB. It creates ozone by splitting oxygen molecules and merging with other oxygen molecules in the air. Ozone is notorious for causing many respiratory symptoms, aggravating asthma, and scarring lung tissues.
How To Prevent And Get Rid of Mold In House?
You have seen the signs, the horrifying stats, the many types of mold, and the health risks it can bring. It’s time to begin with the mold elimination project. Here are a few ways you can get rid of mold and mildew and prevent them from coming back.
- Get a dehumidifier - It reduces the relative humidity level below 50% making it inhabitable for mold and other microorganisms. A dehumidifier will complement a HEPA air purifier well that captures airborne mold and mildew.
- Fix leakage - If you spotted a leaky roof and pipes with clear water stains, replace or seal it A.S.A.P as the humid environment will promote the growth of mold.
- Improve room ventilation - Poor ventilation can lead to stale air and prevent moisture from evaporating. The quickest way is to leave windows and doors open for better airflow circulation. Turn on the exhaust fan in the kitchen during cooking and bathroom after a hot steamy shower.
- Mold protection sprays - There are many types of mold remover products that can instantly kill off mold and mildew on the surface area. A quick and effective solution but you will still need to identify the source of the mold contamination and rectify the issue before it comes back again.
- Kill mold with household items - You can use vinegar, baking soda, hydrogen peroxide, grapefruit seed extract, essential oil, talcum powder, borax, or chlorine bleach. Mix it with water and start scrubbing the affected area.
- Maintainance and care - Routinely inspect and maintain your HVAC system to ensure no mold is growing in the air ducts. Replace/ wash the air filters when it is clogged with biological pollutants.
- Hire a mold remediator - If a catastrophe situation strike like a flash flood, there are little things you can do other than pumping out all the water and post-flood cleanup. You will need to hire a licensed mold contractor to perform full mold remediation. Consider applying insulation and protective coating on the wall to prevent future mold growth.
Do Air Purifiers Help With Mold?
An air purifier can remove airborne mold, mildew, musty smell, and toxic substances by trapping them into the filter. It will protect you from cough, sinus, skin rash, headache, and other illnesses triggered by mold. Take note that you will need to replace the filter regularly for optimal filtration efficiency.
Mold Poisoning Symptoms And Health Effects
According to the Centers for Disease Control and Prevention (CDC), inhaling mold will have adverse health effects. At the initial stage, one might experience mild symptoms like flu, sinus, watery eyes that are hard to call if is mold-related. Prolong exposure can trigger an asthma attack, eczema, migraine, chronic cough, nausea, and diarrhea. The toxicity of mold can also reduce eyesight, reproductive capability, mental disorders, neurological damage, respiratory tract diseases, and liver failure. As mold can survive the harshest condition, it’s always better to be safe than sorry with Mold.
How Many Types of Mold In Homes?
There are 13 types of in-home mold that some you probably never encountered before. Each type varies in size, shape, color, toxicity, and characteristics. Precautionary steps must be taken when dealing with molds to prevent infection.
- Stachybotrys Chartarum (Black Mold)
- Aureobasidium (Pink Mold)
- Serpula Lacrymans
What Is The Deal With Mold?
Here are some interesting facts about mold. Mold is a fungus that prospers in warm, damp, and dark places. It is also a decomposition agent that feeds off dead organic matter like plants resulting in decay. Mold size can be as small as 1 micron (around bacteria size) to as big as a single hair at 80 microns. Because of the size variation, It is hard to spot an airborne mold spore through our naked eyes, and you're at risk of inhaling it.
As mold matures, it releases tiny spores that spread through thin air. The lightweight spores will eventually fall and cling to everyday items such as clothing, wall, upholstery, carpet, floor, and even humans themselves. When disturbed, the spores will easily stir back up to the air and settle on other places to continue with the manifestation. Spores will remain active and allergenic for years to come, which is why action has to be taken dealt with promptly.
Will An Air Purifier Help With Mold?
Air purifiers can help capture mold spores from the air and prevent them from spreading around the house. The mold will have no chance of growth when trapped inside a HEPA filter. If the air purifier comes with UV light, the ultraviolet radiation will destroy the trapped mold and other microorganisms. Allergies and asthma will not be triggered without exposure to mold toxic mycotoxins. Your health will not be compromised.
An air purifier cannot remove mold that has settled on a surface area like floor, carpet, bed, shelf, or wall. It also cannot reduce the humidity level in a home. You will need to perform mold removal treatment or remediation before it starts to grow.
Types Of Household Mold
Not all molds are harmful. There are good molds used in food and toxigenic bad molds that can kill you. Each mold is classified under one of the three groups based on its toxicity towards living beings to differentiate which is which.
- Allergenic Mold. The least dangerous and most common type of mold. Causes allergies and structural damage.
- Pathogenic Mold. A dangerous type of mold that can cause illness, especially for children and adults with a weakened immune system.
- Toxigenic Mold. The most dangerous type of mold that produces mycotoxins byproducts. Black mold comes into mind that can put your health at risk.
Different types of mold will thrive on different surfaces. With more than thousands of mold variants out in the wild, here are 13 common types of mold that can be found in a household.
- Stachybotrys Chartarum (Black Mold)
- Serpula Lacrymans
- Aureobasidium (Pink Mold)
Mold Health Problems
Not everyone is susceptible to mold and may experience different symptoms. Asthmatic/ allergenic persons, children, and the elderly will take a bigger hit. Some allergic reactions are instantaneous, and some might take time to develop. Below are some of the health risks associated with mold:
- Stuffy/ runny nose
- Sore throat
- Headache/ migraine
- Sneezing/ sinusitis
- Watery/ red eyes
- Loss of focus
- Rashes/ skin irritation
- Heart inflammation
- Asthma attack
- Autoimmune disease
- Respiratory tract damage
How To Test Mold At Home
Everyone will have a hard time identifying the types of mold through the gooey slime. Fortunately, there are ways you could test for mold and the severity with minimum effort as follow:
It all begins with a bleach swab test. Gently dip the swab in diluted bleach (1 part bleach, 16 parts water) and dab it on the suspected spot. If the dabbed area lightens after a minute or so, it is likely a type of mold. If nothing changes and the spot remains darkish, it is dust and dirt.
Next, examine the mold spot thoroughly for cracks or crumbling texture. If there is none, the mold is only at a surface area and can be cleaned with bleach, baking soda, or essential oil. If the mold spot feels soft and crumbles when touched, the mold may have infested inside the porous materials like wood or carpet, causing rots and decays. The items might be unsalvageable and require to dispose of.
Lastly, get a hygrometer/ humidity gauge to monitor and manage the humidity levels in your home. Check for leaks as molds need a humid environment to thrive. Follow the water stains direction on drywall, nearby pipes, air duct insulations as there is usually the source of the leakage. The moisture may also leak in from outdoor downspouts during heavy rain. Once you identify the root cause of the mold pollution, take the necessary steps to get it fixed before mold spreads like wildfire.
What Is The Difference Between Mold And Mildew?
Is hard to differentiate mold and mildew as they are often found growing side by side together. Both are a type of fungi with many share similarities. However, there are a few key elements to tell them apart. Learn the differences to have better knowledge of what you are dealing with.
- Appearance. Mildew is easily identifiable with its distinctive white or gray color on affected areas. Mildew also grows in small patches with a fluffy or powdery texture. Mold comes in a range of colors depending on the type. It is fuzzy or slimy, and the colors are typically darker monotone.
- Smell. Mildew tends to have a more distinctive musty odor over mold, but it is hard to tell both fungi apart. When something smells musty, it is a bad signs.
- Structural Damage. Mildew tends to grow on the surface of affected areas that will not damage the structure's integrity. Mold is more destructive and will penetrate below the surface areas on porous materials like wood, upholstery. It is notorious for causing rot, decay, and crack.
- Health effects. Both mold and mildew will have allergies and health risks from exposure. However, you should be worried about mold, more specifically black mold. Black mold releases toxic mycotoxins that can cause upper respiratory tract infections and be fatal with chronic exposure.
- Ease of removal. Mildew can be easily removed with a natural cleaning agent as it typically grows on a surface area. Simple scrubbing should do the trick. Mold is trickier as it penetrates the surface area and grows inside. You will either have to dispose of the item or hire a mold removal expert for assistance.
Mold Air Purifiers Pros and Cons
There are more advantages than disadvantages to owning a mold air purifier. Here are some of the perks that you should not miss:
- Improves air quality - Let's face it, most homes suffer from subpar air quality due to poor airflow circulation. An air cleaner will help create a safe space free from allergens by replacing dirty air with clean air.
- Remove mustiness and damp smell - An air purifier can greatly reduce the unpleasant odors by removing the airborne pollutants causing them. For better results, pair it with a dehumidifier that drains all excess moisture needed for mold to thrive.
- Easy setup - Unlike an HVAC system that requires some wall hacking for installation, a basement air purifier works straight out of the box. Just find a wall plug, plug it in, and you're done. It does not occupy much space, which can be critical in a small basement.
- Easy maintenance - Most basement air purifiers only require quarterly cleaning at most and annual filter changes. There's very little attention needed.
- Silent and efficient - Basement air purifiers can work silently and efficiently without consuming much energy. You can leave the air purifier running 24x7 safely in the basement. Just pick an Energy Star certified mode with auto mode.
- Better health - The wonders of clean air. Having an air purifier will enhance your mood level and reduce stress, as proven by many scientific studies.
- Improved sleep quality - Without mold constantly triggering your allergies, you can enjoy longer sleep quality with good R.E.M. and deep sleep. With quality sleep, your day will be much more productive.
Air Purifiers Limitation
By now, we all know how well an air purifier works with airborne mold. However, mold thrives in dark and humid conditions with poor ventilation. While an air purifier can improve the air circulation part, it cannot change the relative humidity level in your home. You will need a dehumidifier to remove the moisture in a room. Otherwise, there will be a neverending mold infestation in a favorable damp environment. The long-term goal is to manage the number of mold spores from growth and prevent it from happening.
Another common problem is mold reproduction in the filter. When an air purifier is used in a humid environment, there is a possibility that the trapped molds will multiply and escape into the air. This is made worse as some cheap filters are made of paper, a cellulose base that mold feeds on. Always go with an air purifier that uses a certified True HEPA filter made from dense fiberglass.
You can also get around this with an antimicrobial treatment. An extra coating layer will effectively halt the trapped mold or any microorganisms from growth.
What Is The Best Air Purifier For Mold?
An air purifier must come with a true HEPA filter to deal with mold. Not any HEPA-type filter, a certified High Efficiency Particulate Air (HEPA) filter that can capture 99.97% of microscopic particles as small as 0.3 microns in the air. Brands like Alen, IQAir HEPA filtration has even higher efficiency and can capture even the tiniest particles in the air. For reference, most mold spores are range between 1 to 10 microns in size. With the right size air purifier, the HEPA air purifier will work well in places where mold is frequently found, such as the basement, dry bathroom, kitchen, attic, and garage.
Are Air Purifiers For Mold Safe?
Mold air purifiers with HEPA filtration are safe for everyday use as they do not release harmful byproducts to clean the air. To ensure the model you picked is safe, only get CARB certified models from the likes of Honeywell, Winix, or Levoit.
How Much Energy Does A Mold Air Purifier Use?
It depends on the fan speed the mold air purifier is running. On average, the power consumption is between 20-45 watts, which translates to around a $4-6 increase in monthly electrical bills. Compared with other household appliances like a refrigerator or air conditioners, an air purifier is far more energy-efficient than you can comfortably run all day without stopping.
Is It OK To Leave A Mold Air Purifier On All Night?
Not only is it OK to leave a mold air purifier on all night, but it is also highly recommended to do so. An air purifier that runs continuously will prevent mold spores and other microorganisms from lingering in the air and impact indoor air quality levels. There are no harmful ozone byproducts to worry about, and the air purifier will work smoothly if you replace the filters on time.
How To Use An Air Purifier For Mold Effectively?
Using an air purifier properly is a form of art. Not many people know how to get the best out of an air purifier, especially when dealing with allergens that will not go away, like mold. Fortunately, there are a few steps that will help your air purifier maintain its peak performance.
- Always replace the filters - An air purifier that uses mechanical filtration needs regular change. It is recommended to change disposable HEPA and carbon filters every 6-12 months or when the filter indicator light is on. Doing so will ensure the air purifier runs smoothly without hiccups.
- Close to the pollution sources - Mold does not suddenly become airborne; it must have been stirred up from a surface area. Find out where it is and place the air purifier nearest to the sources. If it is close to the wall, leave 2-4 feet of space to avoid any airflow disruption.
- Leave it on 24x7 - A mold air purifier must run continuously to prevent allergens like mold from building up and spreading to other surface areas. Most models come with an auto mode feature that helps conserve energy when there is no need to run at a higher speed.
- Close all windows - Otherwise, an air purifier will be forced to run endlessly as the clean air will flow out while dirty air will flow in. You can still let the sun come in to kill mold with windows closed. Just make sure the air purifier is not directly under the sunlight.
How Long Do Mold Air Purifiers Last?
Most air purifiers for mold will last 5 to 10 years with regular filter maintenance. As for the air filters, the HEPA filter has a lifespan of 12 months, the activated carbon filter will last 6-12 months, and the permanent pre-filter will last a lifetime.
