Best Mold Test Kits of 2022

It’s time to sniff out that mold.

Mold is a naturally occurring fungus, but it can potentially cause harm when indoors. Mold spores can cause allergic reactions and mold itself will cause an unpleasant, musty odor. Some people will experience severe reactions to mold, while others may not be affected at all.

Whether or not you’re affected by mold, having it in your home isn’t ideal. But how do you know if you have mold? One of the things many homeowners choose to do is run a DIY mold test.

These kits are used as a starting point to figure out whether or not mold is present in your home. If mold is detected, further inspection is needed to find the source and determine the genera.

Finding the Best Mold Test Kit

There are multiple choices available on the market, but you must find the right one for you. Here are a few points to keep in mind when searching for the best mold test kit:

Outdoors or Indoors

It’s important first to determine where you’ll be doing the testing. There are separate test kits for indoor and outdoor use.

Lab Analysis

After gathering the required samples, most test kits will require you to send them to a lab. Now, it’s good to choose a brand that uses an independent lab. This will ensure that you get accurate results. Even better, you can find several brands that use AIHA-accredited labs.

Additional Fees

Some test kits might seem affordable, but it’s wise to consider any additional charges. Only a few brands include lab fees in the initial price, whereas others require you to pay extra. It’s also generally the customer who has to pay for postage.


When looking at potential test kits, consider how easy it is to use. A detailed instruction manual is also a plus, so you’ll know how to do the test correctly. We highly recommend checking customer reviews to see how they found the results. Some lab results tend to be confusing, so look for one that might use color-coded results or easy-to-read graphs.

Types of Test Kits

There are different types of test kits to choose between. However, it’s essential to consider what you need from the test kit before settling on one. For example, some kits are for visible mold only, while others detect mold spores and particles in the air. Let’s explain a little further.

Air Quality Testing

This type of test kit will attract particles from the air onto a small cassette or petri dish (depending on the brand). The dish is treated with a “microbial culture” that promotes mold growth. As the dish is left open, it will collect mold spores. You’ll then close the lid and mold should form after 24 hours.

Other air testers will use a small pump to collect air and particles. Some require only a few minutes while others need longer (refer to the manual). You can then collect a dish or cassette and send it to a lab for analysis.

These types of test kits tend to be more expensive, but highly effective. You get to know whether or not mold is present in the air. This also makes it possible to eliminate mold spores before they become actively growing mold (1).

Surface Tests

There are many things hiding in our homes that might look like mold. Mildew is one example of another fungus that’s often confused for mold. Dirt or mud can also resemble mold at times (2).

A surface test generally consists of one or more tape lift samples. To use this, you lift the tape from one side of the sample, then press it gently against the moldy area. You can also use a cotton swab and gently roll it across the area and then on the sticky tape.

You will then have to send your samples to the provided lab. You can expect your results to arrive between two to five business days, depending on the lab and brand. Most brands will provide you with your results via email.

Other surface tests consist of one or more cotton swabs that you roll on the area and then slide into a tube. Inside the tube is a substance that will change color, indicating whether you have mold or not.

How Mold Can Affect Your Health

Mold can be tricky to deal with. We often think that mold will have severe effects on our health, both physically and mentally. However, that’s not always the case. You might experience some symptoms of mold exposure, whereas your spouse may be perfectly fine.

This is because we react differently when exposed. Common symptoms of mold exposure include, but are not limited to, the following:

  • Respiratory issues such as coughing and shortness of breath.
  • Irritated mucous membranes.
  • Fatigue.
  • Nausea or vomiting.
  • Skin inflammation or irritation.
  • Allergic reactions such as a runny nose, red eyes and sneezing.

The Institute of Medicine found, in 2004, that mold and exposure to dampness can cause upper respiratory tract symptoms. The IOM also found that people who are otherwise healthy can experience coughing and wheezing.

A further study showed that mold exposure could be linked to respiratory illnesses in otherwise healthy children. This makes it even more crucial to get rid of mold if you have children (3).

Importance of Testing for Mold

While mold can cause several health issues or none at all, it’s not something we want growing in our house. It’s important to test for mold not only to determine whether or not you have it, but also to know what type.

There are many types of mold; some are toxic while others are harmless. Doing your own testing with a DIY kit is a good start. Then when your collected samples are analyzed, you’ll know exactly what species of mold you’re dealing with.

Different types of mold require different treatments. Some species are easily removed with vinegar, while others require something stronger such as bleach. Killing the source is crucial as the actively growing mold will otherwise spread throughout your home by creating spores.

Detecting Mold

Mold isn’t always visible, which makes it tricky to determine its presence. Here are a few things to help you detect mold:

1. Smell

One of the first signs of mold is a musty odor. If you have smelled mold in the past, you’ll probably never forget the scent. Mold outdoors and indoors tend to smell differently, possibly due to humidity levels and moisture.

Indoors, mold generally smells musty or damp, while it’s stale outdoors. It can become quite pungent and unpleasant. You can usually use your nose to sniff your way to the source.

Keep In Mind

Smelling mold is a tell-tale sign that you have active growing molds in your house. This is not something you should take lightly. You must get further testing done to find proper treatment. Covering up with air fresheners isn’t an option.

2. Water Leaks

If you’ve recently had a water leak in your house, mold is likely going to form. In fact, mold will begin to grow within 24 to 48 hours if the conditions are optimal (4).

You must inspect the area around the leak closely. Do what you can to clean up as much water as possible. If the leak reached a carpet, consider hiring a professional to dry it to avoid mold growth.

3. Health Symptoms

Even if you aren’t allergic to mold, you could still be dealing with a few health effects brought on by the fungus. The mold that can cause the most harm to humans is Stachybotrys chartarum, also known as black or toxic mold. This species produces mycotoxins, which can cause severe health effects (5).

4. Visible Mold

If you see mold growing somewhere in your house, there’ll be no doubt that it’s present. But the real question is: how much is there? If you see small traces of mold, try to follow it to find the source. Regardless, though, the entire area will need treatment.

After examining a variety of mold kit options, our experts have chosen the most effective tests on the market. Each kit was judged on how easy it was to use, effectiveness, price and affordability. Here are the best mold test kits.

1. Home Air Check Active Mold Tests

More still, with the instructions, you’ll also receive a booklet with information about mold. You can learn about inspection, treatment and how to prevent future mold.

The Cons

This kit only determines whether or not what you suspect to be mold is mold. It’s not meant to capture airborne mold spores or particles.

5. My Allergy Detective

The Pros

It will detect common household allergens such as dust mites, mold, pet hair, dander, skin cells, insect fragments, pollen and more. After you receive your results, you can take them to your doctor to find a solution.

Additional Specs

Certified Lab Yes
Any Additional Fees Yes — lab fees

6. My Mold Detective 3-Room Kit

Best Test Kit for Airborne Mold

For effective air sampling, this is one of our favorite kits.

This device is similar to the top product on our list, but this will only detect mold.

The set includes three cassettes for indoor sampling and one cassette for outdoors.

You get fast results and the test only lasts five minutes.

The Pros


Having to spend an entire afternoon, running around the house to collect samples can be frustrating and time-consuming. However, with this kit, all you have to do is place each cassette in areas where you might suspect mold. After five minutes, the cassettes should’ve collected enough samples and you can retrieve them.

Accurate Results

Once the test is done, you’ll know exactly what is growing and floating around in your house. The cassettes attract mold spores, so everything will be tested. This is also an effective way to stop mold spores before they settle and become actively growing mold.

Reusable Pump

Unlike the top test kit on our list, this device is yours to keep. When you need to test for molds again, all you have to do is purchase additional cassettes. With this kit, there’s no need to rent any expensive devices.

The Cons


Unfortunately, there are quite a lot of additional lab fees, which puts off a lot of potential customers. However, you do get high-quality results. Just be ready for any additional charges.

Additional Specs

Detects Airborne Particles Yes
Results Waiting Time Not specified
Certified Lab Yes
Any Additional Fees Yes — lab fees

7. Healthful Home 5-Minute Mold Test

Best Instant Mold Test Kit

If you’re looking for a reliable and quick way to know whether or not you have mold, this kit is for you.

This test kit will give you instant results, so you can start looking for a solution even quicker.

You get a total of four test swabs (one testing swab and three applicator swabs) that you can wipe on any surface where mold is suspected. It’s a foolproof test meant to determine if what you suspect to be mold really is.

The Pros


If you suspect mold in your bathroom, attic, underneath your carpet or anywhere else in your house, this is a quick solution. Simply swab the area and place the sample in the tube. You’ll get your results in an instant.

Easy to Understand Results

Testing for molds feels like testing for urine pregnancy as its interpretation is like the later. Two lines would mean positive result while a single line for control means a negative result.


This test kit comes at a good price point and won’t definitely break your bank. In fact, it’s one of the cheapest in the list.

The Cons

Further Investigation Is Needed

This test kit will only tell you whether or not you have mold — it won’t tell you if it’s toxic. You have to do further testing and inspection to know which type of mold is present.

Additional Specs

Detects Airborne Particles No
Results Waiting Time Five minutes
Certified Lab N/A
