Imagine yourself admiring a beautiful wall in your new home then you suddenly spot a dark grimy spot close to the ceiling. When you move closer, you realize that it’s mold! However, before rushing to buy mold cleaners, you need to get a mold test kit.

Why is owning one important? Because some types of mold are toxic and cause severe skin and pulmonary illnesses. Plus it helps you to identify the correct cleaners for each type.

The Best Mold Test Kit

1. Mold Armor FG500 Do It Yourself Mold Test Kit

3 out of 5 stars (3 / 5)

mold test kitThis three-piece kit identifies a variety of toxic molds in homes, offices, or highly humid areas such as changing rooms. It also enables you to detect and eliminate slow growing mold that is usually hard to eliminate once it’s full blown.

Inside the packaging is a colorless plastic petri dish, a sterile and mold growth medium inside a small bottle. It’s almost the same size as a bottle of eye drops. These are all you need to perform the three main mold tests.

Indoor air quality test

  1. Remove the lid of your petri dish and pour in the mold growth medium
  2. Place the petri dish on top of your coffee table exposed for 1 hour.
  3. Replace the lid and let it sit for 2 days
  4. However, it’s advisable to let it sit for at least 96 hours if you’ve moved to a new property. Why? to check for slow-growing mold

Air conditioning & heating

  1. Locate your unit’s exhaust ventilation then attach your petri dish using tape
  2. Close all vents then let your unit run at its highest setting for 10 minutes
  3. Detach your petri dish and cover it for 48 hours
  4. If you don’t spot any mold after 72 hours, you’re good.

Surface Sampling

  1. If you’ve just spotted mold on your walls, shelves or furniture
  2.  Put a small amount of medium inside the petri dish then dip your sterile swab inside.
  3.  Gently wipe the mold and dip the swab inside your medium.
  4.  Send it for a lab-analysis to identify the type.

The mold medium only enables you to identify the presence of mold. In order to proceed to identification and elimination, you need a lab analysis. Each mail-in analysis costs $40 and you’ll receive the results after three weeks.

2. “WINNER” DIY Mold Test Kit

4.5 out of 5 stars (4.5 / 5)

DIY Mold Test, Mold Testing KitThis DIY Mold Test Kit comes in handy when you’ve just spotted mold inside your home or business. You have the option of choosing either a tape lift or sterile swab in your kit. Inside the packaging is a custody sheet where you provide information about the rooms in which you collected mold samples.

Buyers hate recurring costs. Fortunately, the DIY Mold Test Kit’s price includes testing and shipping fee for mail-in lab analysis. Get this, you won’t pay anything to have the lab mail your results. That’s good news, isn’t it?

Tape Lift

The tape lift consists of a 2X4 inch plastic sticky tape inside a clear case. You can use it on your air conditioning & heating unit as well as surface sample tests. How does it work? First, make sure the wall or furniture is dry. Then, open the clear case and use your tape to rub against one-square-inch of mold.

After gathering your sample, put it inside the clear case. Get a Sharpie then write the room where you got your sample. If you used a tape lift inside your attic, write “Attic” on your plastic clear case.

Sterile swab

You’ll get a Ziploc bag containing a swab measuring about 5 inches and a thin vertical case that resembles a straw. You’ll see a detachable cap that fits on top when mailing your swab for lab analysis.  Just like the tape lift, you can use it to test your air conditioning unit or perform a surface sample test.

First, make sure the moldy surface is dry. Don’t try to collect a sample right after taking a shower. Why? Because humidity will make the mold smear all over the wall, instead of sticking on your swab.

After collecting a sample, put the swab inside the case and label it correctly. You’ll receive your lab report after three weeks.

The Best Air Purifiers:

3. 5 myths about mold

1. Mold isn’t dangerous

Some people wrongly assume that mold is just like any other plant you find outdoors. However, when a small patch grows bigger it releases more spores inside your living spaces. That’s why a musty smell develops and you get nausea when staying in an infested room. A high amount of spores triggers asthma attacks and migraines.

2. Mold test kits are a waste of money

Just because you don’t see mold spores doesn’t mean that they’re non-existent. Mold is present in the air flowing through your windows and the spores settle indoors. Mold simply requires dark places with poor ventilation to develop.

3. DIY kits are inaccurate

The wise man once said that cheap is expensive. However, advanced manufacturing technology makes products more affordable without compromising high standards. A standard mole inspection costs approximately $650, which is why a few people are quick to dismiss DIY kits that go for $40.

4. You can eliminate mold using bleach only

Will scrubbing mold-infested walls with copious amounts of bleach do the trick? Certainly not. The bleach cannot get rid of roots distributed beneath mold patches. It won’t eliminate any additional mold spores hidden inside cracks and crevices.

5. Paint kills mold

This is literally sweeping it under the rug. Painting over mold only destroys the canopies. New growth will develop and eat through your new coat of paint. At this point, the new growth has gained resistance over chemicals found in the paint.

4. How to prevent mold growth

1. Repair leaking pipes

Mold thrives in poorly ventilated confined spaces with high humidity. A leaking pipe increases humidity levels on small areas and that’s just enough space for mold spores to gather and start building a patch.

2. Ensure there’s good ventilation

Why is ventilation important? Because it reduces humidity accumulation as well as clustering of mold spores around one area. Keep your windows open during the day and get a fan for poorly ventilated rooms.

3. Use an air purifier

Air purifiers contain HEPA filters and UV chambers that trap and degrade mold spores. Having an air purifier at home or your office prevents mold from springing up again.

4. Get a dehumidifier

A dehumidifier regulates the amount of humidity inside confined spaces. Adding this unit to your basement or closet makes it hard for mold spores to survive.

Test your home or office today!

Waiting to see mold growing on your leaky ceiling or damp closet is far from wise. We’ve seen that mold spores trigger asthma attacks, migraines, and a variety of skin diseases. Especially where you have children present. Allowing mold to build up directly affects the health of your loved ones.

On the other hand, getting a mold test kit is the first step towards getting rid of that musty smell and illnesses. You’ll be able to do an accurate home inspection by purchasing a kit for each room with humidity problems.
