A mold test kit can help you to know if you’ve got mold in your home or not. This can help to stop and even prevent many illnesses that often result from mold buildup in homes.

There are, however, as many mold test kits as there are micro-organisms. So, it’s easy to get overwhelmed when you’re shopping for a kit.

But this mold test kits review throws light on the issue and makes it easier for you to choose by taking a look at the market’s top offers below.

How to Buy the Best Mold Test Kits

1. Types of Molds

There are many types of molds, from black molds to penicillin and so many others.

So, it’s practically impossible to test for them all, but a good test kit should test for as many of the most common molds as possible.

If you don’t know what you’re looking for, then go for a kit that tests for the widest range of spores.

2. Types of Tests

There are different types of tests and they come with their pros and cons. The most popular are air testing and surface testing.

Most kits are either designed for one style or the other, although some kits come with tools for more than one testing style. Here’s a closer look at each type.

– Air Testing

This simply means trapping the ambient air and the spores it contains onto a mold growth medium.

This can involve leaving a petri dish open in the room for some time or using other methods of air extraction, such as the more expensive MyMoldDetective MMD105 air pump kit.

– Surface Testing

Surface testing is best used when you can visually identify the source of the mold spores. It generally involves rubbing the surface area with a swab to pick up fragments of the suspected mold, or pressing a piece of adhesive tape over the area, so it can pick up samples.

– Bulk Testing

With bulk testing, you have to physically pick up a piece of the sampled area and bag it safely for sending it to a lab.

3. Test Precision

All mold test kits offer varying levels of precision and reliability, so it’s often difficult to know which manufacturer to trust.

A good strategy is to go with the tried and tested: products that have received plenty of good reviews.

On the other hand, testing laboratories that are accredited by institutions such as the AIHA should provide more credible services.

4. Safety

If you follow the manufacturer’s instructions properly, then using mold test kits is safe and there should be nothing to worry about.

In the case of keeping a petri dish for a few days to check for mold growth, try and keep it away from children’s reach.

5. User Friendliness

Another factor to consider is user-friendliness, which can take many features into account.

They include simple operating instructions, an easy-to-understand user manual, and an overall simplicity that makes it usable by a wide range of people without getting too technical.

6. Test Duration

Because all the tests work differently, they also have different durations to get a result. Instant tests such as the Healthful Home HH2003 to confirm the sheer presence of molds can take just minutes, while you’ll need up to five days to see if you’ll get some growths in a petri dish.

When it comes to samples sent to labs, this will depend on the individual lab, but they can range from just one day up to two weeks to get you a report.

  • Result Duration: 5 days

If you’re sure you’ve got mold in your home or office, but just can’t tell the source, then here’s probably the best mold test kit for you.

So, you could test all the rooms in your house and then, analyze the mold count from each room after five days incubation to find out where you have the highest concentration, which will also be the source.

That five-day wait might be a drawback for some but it’s worth it. You can also take extra samples after you’ve found the source, and mail them to the lab for a detailed report.

  • Contains 10 tests per kit, making it cheap
  • No need to mail in the samples & no extra costs
  • Easy to follow instructions

Such a system guarantees better results than petri dishes, which can fail to trap mold spores, especially in rooms with a low concentration.

How To Use Mold Test Kits?

Step 1 – Start with Hygiene

Hygiene is very important here because you’re dealing with micro-organisms. So, make sure to wash your hands properly with soap before opening the test kit and touching the tests.

Try to maintain as high a level of hygiene as possible, so you don’t contaminate your samples and corrupt your result.

Step 2 – Prepare the Room

When possible, try and close all doors and windows in the room that you intend to test 24 hours prior.

This is necessary to increase the concentration of potential spores and improve your test accuracy.

Step 3 – Prepare the Test

The different tests have different preparations. So, you’ll need to read the manufacturer’s instructions here.

Regardless of the type of test you’re using, try to maintain a high level of hygiene when handling the test kit.

Step 4 – Follow the Instructions

Some kits need you to open a petri dish and leave it in the room for an hour.

Others come with a sterile swab or tape to physically pick up surface samples, while even more professional systems use an air pump to pick up as many spores as possible for testing. Just follow the manufacturer’s instructions here.

Step 5 – Check Results & Mail-ins

After the test period, you’ll either get an instant result or you may have to mail in the sample to the designated laboratory for confirmation and a detailed report.

Test sticks take a few minutes, while Petri dishes need 5 days to confirm if there’s a growth or not.


We’ve come to the end of this mold test kits review and you’ve seen the best the market has to offer. Now it is your turn to make a choice.
