How Did We Choose These Mold Targeting Models?

There are some specific qualities that you should look for before investing in an air purifier, especially one that deals with mold.

It Should Cover a Good Area

Mold, as mentioned before, can be really persistent. Since it spreads very fast and with unbelievable ease, the purifier should have a larger room capacity. The reason behind this is so that your purifier can tackle the mold spores more efficiently. Otherwise, mold will keep growing and the purifier will have little or no effect.

Adjustable Settings

This is another important feature that you should look into before choosing an air purifier. Adjustable settings enable you to set the device according to your needs.

Maybe you do not need a powerful setting to deal with your problem or maybe you need a more powerful speed to eradicate the spores quickly. In any case, you should have the liberty to decide.

Quality of Filters

Quality of the filters is something that should always be a priority. A good quality filter will obviously work better, more effectively, and efficiently, while a lower quality one will not work effectively and will need to be replaced frequently.

Since choosing the best amongst so many is not an easy task, we have compiled a small list of some of the best air purifiers for mold. Each product will have an in-depth review so that you can get the best idea of all its features and pros and cons.

This filters out all unpleasant odors.

Although the Blue Pure 211 is small in size, it can easily cover up to 540 square feet of area. Furthermore, it does not produce any loud noises when it functions.

This air purifier by Silver Onyx is a great product to explore. It is equipped with many different features which make it a great product. First of all, it does not look like your everyday air purifier at all. In fact, it somewhat resembles a coffee grinder. Secondly, the five-stage filtration process is very interesting.

The first step of the process includes a preliminary layer made of mesh. This layer only gathers the larger particles from the air making sure that the other layers only have to deal with the finer particles. The second step is the True H13 HEPA filter. This treats the air and makes it clean and crisp.

The third layer of the purifier is a carbon-activated filter which does away with any unwanted smells. The next two steps include the negative ion generator and the UV light sanitizer. The negative ion generator does not always remain on; you can turn it off if wanted. Meanwhile, the UV light sanitizes the air by killing viruses and bacteria, cleansing the air completely. This purifier has the room capacity of 600 square feet which is higher than any average product can cover.

This air purifier is the classic 3-in-1 style air purifier. It features a pre-filter which gathers the heavy-duty particles before the air is passed through the other filters. Next in line is the True HEPA filter. This filter can treat particles as small as 0.3 microns. The particles that filter treats are dust, mold spores, pet dander, and other microorganisms that act as allergy triggers. The last step is the UV-C light.

What Recent Buyers Report

Most recent buyers agree that the TruSens Z-3000 is compact and sleek and thus easily blends with any interior décor.  The machine’s sensor is highly accurate and can easily detect your air quality. If you suffer from any allergies or asthma, you will enjoy better health due to the effective elimination of mold and other allergens by the true HEPA filter. It is very effective at reducing mold exposure.

Why it Stands Out to Us

The TruSens Z-3000 uses a 360-degree filtration design that enables it to draw air from all directions, where other purifiers only draw air from the front. This design increases the air cleaner’s efficiency.

This HEPA air purifier comprises a dual airflow that splits air into two streams delivering more purified air filtration as compared to a single airflow.

It combines a true HEPA filter and a UV-C light to capture and destroy any mold spore, dust mite, or any other allergen in your room. It even includes an activated carbon filter to remove household odors. We especially like that the HEPA filter and carbon filter have separate replacement indicators, so you only need to replace one at a time.

The SensorPod monitors the room and aggressively acts to ensure that the air quality is in check. If you place the purifier in the opposite direction, a signal is sent to the air purifier to automatically adjust the fan and remove any airborne particles.

Bottom Line

The best thing about a TruSens Z-3000 is that it combines 3 key filter types to handle large, small, and tiny particles. Despite the intensive filtration, it maintains an excellent clean air delivery rate. With a TruSens Z-3000, you are assured of a machine that will strip all contaminants from the air you breathe such as pollen, viruses, smoke, and mold.

How Do Air Purifiers Remove Mold?

There are a few different techniques that are used to remove mold with the help of air purifiers. All of them are listed below.

UV-C Light Filter

This filter uses a strong UV-C light to destroy the makeup of the mold particles completely. With a 100% accuracy rate, they eliminate even the smallest mold spores from the air.

Blue Pure 211+ Air Purifier for Home

True HEPA Filter

This is perhaps the most popular option. This filter is found in many air purifiers. It helps trap particles as small as 0.03 microns, which includes mold spores as well.

Activated Carbon Filter

An activated carbon filter helps to eradicate the foul odor that often accompanies the mold.

What Makes An Air Purifier Great for Mold?

Here are ways a purifier helps with mold.

UV Light Capacity

Do you have an air purifier in your home but you continue to experience mold growth on your walls? Well, not all purifiers can effectively remove a mold spore from the air, most of them can only remove particles such as dust.

This is why it is recommended that you should use a UV air purifier. It comprises a UV c light bulb that is located in the innermost part of the purifier. This light produces electromagnetic energy that destroys the DNA of microorganisms, preventing them from reproducing, and eventually killing them.

Mold grows in dark areas where sunlight does not reach. Therefore, if the UV light is directed towards the mold, it will kill the microorganisms. It is, however, important to note that as you begin the cleaning process, you might disturb mold spores and in this manner, you send them back to the air you are treating. As such, use UV light regularly to stamp down any mold that has moved into the air.


Another feature that makes an air purifier great for mold control is portability. Portable air purifiers can be moved from one station or room to another to ensure that all spaces are free from mold. If this is not done, mold from other uncleaned parts will easily find its way into the previously cleaned areas. 

How Does an Air Purifier For Mold Work?

Air purifiers have a high-efficiency particulate air filter that is used for removing particle pollutants. They are thus able to trap dust particles present in the air.

The UV bulb acts as a sanitizer in the last stages of filtration. The UV light also plays a major role in eliminating mold. It produces electromagnetic energy that destroys the growth of any microorganism including the spores that grow into mold.

A good air purifier also comes with a sensor to monitor air quality and an air quality indicator. These can easily detect the presence of mold. This means that the entire mold control system becomes automated so you don’t have to worry about making any regular adjustments to the air purifier.

Benefits of Investing in a Quality Air Purifier for Mold

Quality air purifiers come with many benefits. Here are a few of them:

Elimination of Mold

As a given, a high-quality air purifier with a HEPA filter and a UV sanitizer will be effective in the elimination of mold in the air. A HEPA filter catches the mold spore, and the UV light destroys them before they can go on to cause further mold growth.

Improved Respiratory Health

When you invest in a high-quality air purifier for mold, you are guaranteed better health because of the elimination of the heavy mold spores that could trigger a mold allergy or otherwise cause breathing difficulties, sneezing, or coughing.

Balanced Humidity Levels

Although air purifiers do not remove moisture from the air, the reduction or elimination of mold will eventually lead to reduced humidity levels within your space. 

This is possible because if the air is already saturated with moisture, the excess moisture holds on to other particles in the air such as mold. The removal of the mold thus means only the moisture attached to air particles themselves remains within the space.

Furthermore, the elimination of mold reduces the chances of the mold settling and growing on surfaces like walls and floors. When these mold balls are eliminated, there will be less space for the trapping of excess moisture within the room.

Air Purifiers for Mold Comparisons

How do air purifiers for mold compare?

Air Sanitizer vs Air Purifier Effectiveness Against Killing Mold


  • Both aim at ensuring that the air is clean and healthy for breathing.


  • Air sanitizers mainly target living organisms while air purifiers mainly focus on eliminating particles and can only eliminate mold in small amounts unless they have UV light or generate ozone
  • Air purifiers help reduce the concentration of mold while air sanitizers get rid of the mold completely.

Air Purifier vs Dehumidifier For Mold


  •    Both the air purifier and dehumidifier eliminate mold from the environment.


  • An air purifier removes air pollutants from the air but a dehumidifier doesn’t and only works to regulate humidity levels
  • An air purifier can prevent mold from building up. However, it cannot regulate humidity levels that cause mold to accumulate
  • A dehumidifier eliminates moisture from the air and can therefore reduce humidity levels while an air purifier cannot eliminate moisture.

UV Air Purifier vs Ionizer For Mold


  • The UV air purifier and ionizer purify the air from pollutants.


  • The UV air purifier uses light to destroy mold spores while the ionizer clumps mold spores and causes them to drop on the floor or other surfaces from which they can be wiped or swept off.


The air purifiers discussed in this article are a small list of the best purifiers which will help you deal with mold spores. However, it should be kept in mind that these only help eradicate the mold spores from the air and do not deal with mold directly. Apart from that, they also deal with other allergens as well and provide you with clean and crisp air to breathe, so make sure to make your pick wisely.

People Also Ask

Most people don’t give much thought to air purifiers. As long as they are working well, we become satisfied. Nonetheless, there are moments when questions arise on how to keep the air purifier working at its best.

What Air Purifier Setting to Remove Mold Spores?

The Air purifier consists of UV-C light that destroys mold in the air completely. So how does the UV-C light work? The light produces electromagnetic energy that terminates the DNA of microorganisms such as mold. This prevents them from reproducing and eventually kills them.

How Long Do I Need to Run an Air Purifier to Kill Mold?

An air purifier has a timer function to enable you to control the number of hours it runs. You can, however, set the purifier to run during the night and turn it off during the day. For the best results in eliminating mold within a particular time, it is recommended that you should leave the air purifier to run for at least 18 hours a day.

Will an Air Purifier Get Rid of Black Mold?

It is important to note that an air purifier cannot remove black mold. This should be physically removed and the surface cleaned using a bleach solution. An air purifier will only remove mold from the air and in your surroundings. However, you should consider a high-capacity purifier that has a high flow rate. If the air purifier consists of a UV bulb that produces electromagnetic energy, it will be able to destroy the growth of any microorganism including mold.
