Bests & Worsts Reviews from Amazon

Only one kit is in a pack and the directions clearly state that to understand whether or not you have higher than normal levels of mold you need to get an indoor and outdoor reading. In fact, when you dig into mold remediation companies and mold in general you'll find that you need to basically test every area of your home at least twice and compare it to one or more outdoor samples to get a read on whether there's excess mold in your home and if it's different than what's outside. Even then, you don't know if the mold you found is benign or harmful unless you pay for a $40 test. That's fine, if you suspect an issue it's fair to have it sent to a lab for testing. The problem is that most people don't know that every home has mold in it. Some of that mold can even be the harmful kind. The trick to it all is that even with harmful mold it really won't affect you unless it is growing out of control at levels above what are considered safe, even for the harmful variety. So as a test this works fine. I found mold growing in my daughters room and it was concerning. I removed the mold with a bleach solution and then ran this test a few days later to see whether or not there was the same kind of mold and an abundance of it. I left the Petri dish out for 3 hours instead of the recommended 1 hour and after 48 hours there were 2 of the tiniest mold spots growing in it. After 96 hours there were 3 of them, I could tell they were the same type I had cleaned off the wall and none were more than the size of a quarter. This tells me that there isn't a substantial mold issue in the room and that I need to continue to monitor the area where I first found it. Again, we're back to not knowing what the baseline for the home is because you have to buy multiple kits and test outdoors to get that baseline. So I base this off of the results of others in similar rooms that I've found online. There is a 99% chance you will find mold with this test. That isn't necessarily bad. All homes have mold. You need to have a way of knowing whether there is some area that is consistently allowing mold growth, if the levels of mold growth are too high to be safe, and if the type of mold is dangerous to breathe (not all are). So be careful reading these results. The presence of mold doesn't mean you have an infestation and need remediation. All homes have mold. Best thing I could say is pay the $40 fee to get it tested to see if it's dangerous mold and even then you'll need to know whether it's consistently getting in your house and if the level of mold in the air is at a point where it's harmful to health which just can't be done without an expert coming out to test. This product is really best to give one piece of mind after they've cleaned some mold. For me it let me know that yeah, there's still mold in the air but it isn't growing on the wall where I found it anymore and after taking a sample 3 times longer than the directions asked for I still only got minor growth after waiting 4 entire days.
