What Air Purifier is Best for Mold?

best air purifier for mold

Mold plays a crucial role in the eco-environment outside. However, when the spores from this organism come into our home and start reproducing, they can create serious health effects. This is one and the most important reason to why we need to take care of mold and get an air purifier against them.

When it comes to choosing such a device, you might want to consider a good air purifier for allergies as well, because sometimes mold leads to such problems. Another thing to think is where it will be placed. Will it be at your house, office or underground? We will look into all of that and more, to get you fully equipped with information, to make an excellent decision for your situation.

What is the “Go-to” Type of Air Purifier for Mold

There is a wide variety of technology that an air purifier can have, sometimes even in combination. Now we will look at all of them, we will say the advantages of each one if they have such. However, because everyone has different standards, we leave to you to decide, which one would be the best for your price point.

  • HEPA filter – The standard HEPA system can remove up to 99.97% of particles, in sizes bigger or as much as 0.3 microns. For reference, usually, mold spores are more substantial than this size, which means that they will be trapped by the filter. Smaller once can pass through, but the problem here is that mold can start growing on the surface of the system.
  • PECO – This stands for Photo Electrochemical Oxidation, it uses light-activated catalytic reaction, which destroys all particles that pass through the system. This is an advantage over the HEPA because it doesn’t allow for the organism to grow on its surface.
  • PCO – Photocatalytic Oxidation is a forerunner for the PECO variation. The difference here is that it is inefficient and can generate ozone, as a side effect even cause irritation to the respiration system.
  • UVGI – Ultraviolet germicidal irradiation is meant to sterilize air thus killing any bad organisms such as mold and viruses. Even though EPA implies that as efficient, to do it, it has to create an intense UV radiation, more than what a home unit is suitable for.
  • Carbon filter – This type is used to remove airborne chemicals from the air, by trapping the gases on an activated carbon filter. This type exists, but it is not suitable for the removal of mold spores, because it is not intended to do so.
  • Ionizing Air Purifiers – They make the particles stick to the nearby surface, thanks to an electric charge. They are successful in doing this; however, they have a lot of drawbacks that make them unworthy of using. Much like PCO, they generate ozone, which is harmful and shouldn’t be breathing it.

Air Purifier for Mold Buying Guide

The Top 5 Things to Look for When Buying an Air Purifier for Mold

  1. Filter

    This one is the most crucial elements. The best you can get is an air purifier with a 2-stage filtration system. A good option is a model with a HEPA and an activated carbon filter. Because they will remove from the air both the odor and the mold spores.air purifier for mold reviews

  2. Speeds/Levels

    This is just a more useful feature to have because it allows you to control the rate of air circulation. For instance, during really humid cold weather, mold grows quicker so you can set up the fan on a higher level to get an excellent complete clean.
    Meanwhile, during warmer weather, you can turn it down and ventilate by opening your windows. Some models have a smart sensor, which makes them evaluate the quality of air and make adequate changes depending on the mold pollution in the air.

  3. HEPA filter

    There are other types of filters as well, but we recommend this one because it captures spores that are the size of 0.3 microns, which is more than satisfactory for mold spores.
    Now, there are different types of filters, there are “true-HEPA,” “HEPA-style” or even “HEPA-grade” filters. The one that performs best is the true-HEPA, however, if you are restricted by a specific budget, a device with a HEPA-grade will still play well.

  4. Automation

    : We did talk earlier what it means to have a smart sensor, where the device assesses and makes changes according to the quality of air. We are mentioning it again as more of an additional feature, if you have a bigger budget, it just makes things more precise and easier, either getting the best budget air purifier is a priority.

  5. Noise and lights

    That varies on the model, some make more noise than others, and some have fainter lights, in comparison to other devices. They aren’t something crucial to the performance of purifying the air; however, it is good to be aware of them, especially if you are someone who can’t sleep if there is any noise or light close by. Now that when you read reviews in regards to this, it really depends on one’s tolerance, some might find a particular machine really quiet, while another one complains how noisy it is. But in all fairness, this is a trait which almost all heating systems share, and we’ve discussed it in our articles.

Things To Consider When You Are Buying An Air Purifier For Mold

There are a lot of factors to keep in mind when looking at devices for air purification. Some of them include the technology of the item or the area it can cover. But let’s take a look at why do these things matter.

  1. Technology
    There are different types of techniques when it comes to these devices; however, some of them produce better results when working together. For instance, HEPA or High-Efficiency Particle Arresting filtration, along with silver ion technology and UV light is a good mix.
    Firstly HEPA is the central filtration, which removes as much as 99.97% of airborne particles at 0.3 microns or more. The advantage of having the additional silver ion technology when it comes to mold growth is its antimicrobial properties. Finally, the added UV light will keep your HEPA filter, and it’s surface clean and safe from mold spores growth.
  2. Coverage
    Every device has a specific coverage area, within this limit it produces amazing optimal results. This is why it’s vital to place such item in square footage that is within its limit of covering. For instance, what we mean by that is if you have a mold air purifier that can perform well in a 400 sq. Ft., then it should only be placed in a space that is up to 400 sq. Ft. big or less. If you put it in a bigger room, then the performance will suffer.
  3. Warranty
    This might seem like something that isn’t really essential; however, the mold is always present. Because of this, it is common to get it inside our houses. And since even if you do terminate it, it can still come back pretty quickly, you have to invest in a device that will last in an inevitable future. To know you are covered on this, check the warranty on your air purifier.

Mold Health Effects

benefits of air purifier for moldSo we looked into air purifiers, how all the different kinds of work and what features are vital for a good performance, but now let’s look at why you need one in your home?

Even if the mold wasn’t a factor, us humans when we are exposed to damp environments we can start developing different health issues, depending on our sensitivity. However, we are going to look at mold specifically, because some people are more susceptible to it. For such people, these organisms can lead to nasal stuffiness, coughing or wheezing, irritation of the throat, eyes or with some, even on the skin. Other individuals have mold allergies, which cause more intense reactions.

Those who already have chronic lung illnesses or have problems with their immune system can get severe infections in their lungs when exposed to mold. This means that they in no case should get in areas that can have mold, such spots are cut grass and wooded areas. If somebody in your family is prone to this, it might be a good idea to consider getting a good whole house air purifier.

There have been many studies throughout the years that found a link between indoor mold and upper respiratory tract symptoms, such as coughs, asthma and more. There are many mold еffects on human health, and we recommend reading more about it, especially if you know someone who suffers from problems related to mold spores.

How to Test for Mold in the Air?

Viable mold test kits are one of the more popular ways to test your air due to their availability in home improvement stores and online retailers. But it does vary from one test kit to another. It is important to know that some of them are designed to only test if mold can be found on surfaces. If you want to test if it’s in the air you breathe, you need to know how to check your air quality.

The whole process of testing takes a few days, and if in the end, it shows positive that you do have mold spores in the air, we recommend you send the test materials to a lab. Because it will perform a further examination into finding out what type of mold exists exactly.

Keep in mind that the US Environmental Protection Agency does not support any kind of home mold test kit. In fact, it endorses homeowners to get their homes professionally tested if they question the presence of mold. So know this if you decide to use do-it-yourself kits.

What is Black Mold?

What is Black MoldTo put it just the name comes from the very dark green or black color of this type of fungus. It has a specific musty or damp, mildew odor. It can be one of a variety of spores, such as Stachybotrys chartarum. It usually grows on finishes that include cellulose, such materials are fiberboard, wood, gypsum board, or paper. Overall mold can grow easily and quickly in conditions where it is warm and humid.

The same goes for Black mold and rooms that have these exact circumstances are bathrooms and shower cubicles. However, it can be found in other areas where you can’t spot it easily, such as a burst pipe or flooding or even between the layers of a wall or underneath carpets and floorboards. If you are also looking for portable carpet cleaners, do your research.

This type of mold is not dangerous in themselves; however, they can release unhealthy, risky toxins into the surroundings. If inhaled, the viruses can cause health issues and symptoms. People with chronic respiratory problems are even more susceptible to this and have a higher risk of experiencing them. This is also why such people get a fantastic air purifier for allergies because it helps deal with things that can trigger their problems, in addition to mold spores.

Tips and Techniques for Mold Cleanup

When you are preparing to clean mold, you have to consider a few things first. Initially, if the moldy area is less than 10 square feet than most of the time, you can take care of it by yourself. However, if there was a lot of water damage, and/or the growth is more significant than 10 square feet, we suggest you consult EPA guide Mold Remediation in Schools and Commercial Buildings.

To help the process of cleaning and stop the spreading of mold, make sure you fix any kind of plumb leakage or other water problem you might have. Dry everything, then scrub off hard surfaces with detergent and water, and once again dry it thoroughly.

Sometimes you might have to throw away molded materials, such as ones that are absorbent or porous, these are ceiling tiles or carpets. That is because mold goes into the empty spaces and pores, thus making it really hard or even impossible to get rid of altogether.

It is also necessary to know what to wear when moldy cleaning areas. Do not expose yourself or others to the fungi. Also, if you are going to paint over the surfaces, to cover up the problem, you first must wait for it to dry entirely. If you rush and do it, it is indeed likely that the paint will peel.

If you have to clean an expensive or essential item, it might be a good idea to consult a specialist, someone in furniture repair, restoration, etc.

How to Control Mold Growth Inside Your Home

We already talked about some tips on how to control mold growth inside your home, because they relate back to other stuff we mentioned, but briefly say again you can work on this by:

  • Monitoring the levels of moisture;
  • Fixing leakages on pipes, roofs, windows and checking them periodically;
  • Extensively cleaning and drying after flooding;
  • Ventilating areas with higher humidity, such as cooking, shower, and laundry areas.

It is important to note once you clean up the mold, you also need to fix the moisture problem, that leads to the growth of fungi. You can remove mold from hard finishes with commercial products, such as soap and water. If you choose to use bleach, 1 cup of household laundry bleach is to be used for 1 gallon of water.

If you decide to try this method of cleaning, with bleach, then you need to know this:

  • Under no conditions mix bleach with ammonia or any other household cleaners. If mixed, they will create dangerous, toxic fumes.
  • While cleaning, ventilate the space well, and open windows and doors for fresh air to come in. In case of bad weather, use your ventilation system.
  • Wear non-porous gloves and protective eyewear.
  • Make sure you follow the manufacturer’s instructions when using any kind of cleaning product.

Mold Prevention Tips

You can work on some things that will stop or minimize the growth or existence of mold contamination. These things are:

  • Cleaning routinely rooms such as bathrooms, showers and other humid rooms, because they are more likely to birth mold.
  • To prevent moisture from building up and lead to the continuation of mold spores, you can use a dehumidifier in spaces where the damp is an issue. This way you don’t create the right conditions for it to thrive in.
  • Keep all surfaces and walls, floors, ceilings dry.
  • Ventilate well and keep spaces warm during cold, stormy weather. Cooling and heating your house does play a significant role when it comes to taking care of mold spores.
  • In bathrooms and kitchens, to not build up any odor or moisture use exhaust fans, and avoid having carpets or rugs here. Something handy here is getting a great dehumidifier for basements, which can help with moisture building into your home.
  • Because there are occasions when mold grows in a space that is hard to see, we advise regularly checking things such as pipes, gutters, and air conditioners. This will prevent potential leaks and water damage.

How Do Air Purifiers Help With Mold?

To just explain, the fungi, which is mold release spores into the air. Then they float about until they make their way into your lungs as you breathe them in. If there is an air purifier, it will draw air into its filter, remove particles, such as mold and then push out the clean air back into the room.

This is at the basics; however, more things play a role, because some filters need additional protection so the mold won’t stick to its surface and start growing there.
