Mold can grow anywhere it finds moisture and organic nutrients, like wood or paper, to feed on. You may find it in a corner of your bathroom, laundry room, or basement, or any space that doesn’t have quality ventilation. If you come across mold, it’s imperative to remove it quickly and safely, as mold can be detrimental to your familys health. However, it can be a little difficult to know if mold exists in your home , which is where at-home mold testing comes in.

Mold testing kits help you detect and even identify growing spores in your home, through samples collected via the air or from the surface in question. Some give you results right away, while others ask you to package the samples and send them back to a lab for professional examination. With the resulting information, you can get the peace-of-mind that you’re looking for while making all of the necessary arrangements to remove the harmful fungi, or know your cleaning efforts were effective.

Here, the best at-home mold tests, that are both easy to use and effective.

Reasons Mold Test Kits Waste Your Money

  • The most important part of a mold inspection is the inspection, not the mold samples.Mold samples can be misleading, are sometimes incorrect with both false positive and false negative results occurring, and can only be accurately interpreted in conjunction with a well thought out sampling plan and visual inspection. The visual inspection requires an understanding of building construction, water sources, and other factors that may not be apparent to many people, such as condensation occurring in a poorly ventilated attic, poor drainage on the exterior of a building, or cracks in the foundation.

  • Consumer Reports rates home mold test kits “Not Recommended“.In 2006, Consumer Reports evaluated four different types of home mold testing kits and rated all of them “Not Recommended,” including typical comments like this one for the Pro-Lab MO109 mold test kit:

  • “In some samples, the vials with media leaked over entire kit. In one, an unopened kit was moldy. No expiration dates on the kit old media could affect the accuracy and reliability of the results. Label claims that kit can identify toxic mold, but the report the lab sends can’t tell you this. One unused plate came back positive for mold growth, indicating contamination at some point not very reassuring for post remediation use.”

    Mold Armor Do It Yourself Mold Test Kit

    by Mike Mulieri | May 12, 2020 | Generic Mold |

    If you are a consumer who believes that there may be some presence of mold in your home then you generally have two alternatives 1) An over-the-counter home mold test kit, or 2) Hire a mold inspector.

    An over-the-counter home mold test kit may seem like an appealing and more affordable alternative than hiring a home mold inspector but there are some important facts you should keep in mind before investing in one of these kits.

    Mold Armor Diy Mold Test Kit

    Complete with a petri dish and mold-growth medium, this Mold Armor kit is suitable for testing indoor air, ventilation systems and surface areas that show visible mold growth. This kit shows the presence of mold after being exposed to the air, but a $40 test fee is required to find out what kind of mold youve got.

    Other Disadvantages Of Using A Home Mold Test Kit Include:

    • When mailing your kit to the lab for analysis, you risk inaccurate results because you dont know whether the specimen was handled properly during the shipping process.
    • Dont panic when we say this but there are always mold spores floating in the air we breathe, meaning your home mold test kit will more than likely show a positive result. The key information missing is where the level and growth of the mold is, and how to remove it.
    • Mold kits dont provide a control sample, therefore, without a baseline, you arent able to assess the level of elevation of the spores.
    • The United States Environmental Protection Agency advises against home mold test kits. They advise leaving this to the professionals, like MoldGone. Heres what the United States Environmental Protection Agency has to say about mold testing:

    Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, sampling methods, and interpreting results. Sample analysis should follow analytical methods recommended by the American Industrial Hygiene Association , the American Conference of Governmental Industrial Hygienists , or other professional organizations.

    Reputable mold test companies include their telephone numbers and email addresses on their websites. In addition to contact information, you might want to select a company that has strong support options, including FAQs and video tutorials.

    How To Remove Mold

    • Wear old clothes and shoes that you can launder or throw away after the cleanup work.
    • Wear special N-95 or P-100 respirators, in addition to goggles and gloves.
    • Set an old box fan or a cheap new one in a window to ventilate the room while working. Throw it out when you’re done cleaning, because the spores are almost impossible to clean off. Tape plywood or cardboard around the window openings so the spores can’t blow back in.
    • Wrap and tape moldy carpeting in 6-mil plastic, and double-bag mold-infested debris in garbage bags for disposal.
    • To control airborne spores, moisten moldy areas with a garden sprayer while you work.
    • Turn off your furnace and air conditioner and cover ducts and doors to contain spores.
    • Keep your wet/dry vacuum outside when you vacuum.

    Does A Mold Air Test Really Work

    By Jennifer First published: . This post may contain affiliate links.

    • 34

    When it comes to testing for mold, there are many options available. One such option is the mold air test also known as air sampling for mold.

    There is a lot of controversy relatedto conducting an air test for mold. On the one hand, it typically is the onlymold test that is considered admissible in a mold related lawsuit. It is alsotypically the only mold test that will legally allow a tenant to break a leaseor rental agreement. Therefore, it has become somewhat of a standard when itcomes to testing for mold.

    On the other hand, mold air samplesare highly unreliable and inconclusive making them a possible waste of valuabletime and money. So whats the deal? Should you conduct an air test for mold orshould you use another mold testing option?

    How To Use Black Mold Test Kits

    The first type of test kit tests for mold on surfaces. Read the instructions thoroughly to be sure that you complete the test correctly. Most of the kits will require you to swab the affected area with a Q-tip, and then rub the Q-tip in a dish that contains a substance that helps the mold grow. If the testing dish begins to grow mold, then you will know that mold is present on the surface that was swabbed.

    The second type of black mold test kits that are available focus on testing the air for mold spores that may be present. Like the first type of test kit, these kits use a dish with a mold growth substance to see if mold colonies grow. Instead of using a Q-tip, though, the dish is allowed to sit open in the room for about an hour. Once the hour is complete, a lid is placed on the dish and it should be checked in a few days to see if mold has grown.

    The drawback to both of these types of tests is the fact that they cannot identify the type of mold that is present. Additional testing is needed to determine the exact type of mold that you are dealing with. They also will not tell you how severe the problem is.

    Winner Diy Mold Test Kit

    This DIY Mold Test Kit comes in handy when youve 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 Kits price includes testing and shipping fee for mail-in lab analysis. Get this, you wont pay anything to have the lab mail your results. Thats good news, isnt 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

    Youll get a Ziploc bag containing a swab measuring about 5 inches and a thin vertical case that resembles a straw. Youll 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.
