I have had gnat problems around my kitchen sink for the last few years. I think there is a problem with mold or mildew. Had plumbers look at it. They said to use bleach. Bleach only works for a short term effect. But, I want long term results. Saw these little gray pouches online. Ordered three. Gnats are gone, possible mold in the drain is gone. I am a neat freak and allergic to many toxins, mold, mildew, pollens, dust, etc. These little gray pouches have eliminated mildew smell.
Since my initial purchase, I've ordered three more sets to give to family members. I don't understand how these packets are working for me, but not for all the people with negative reviews. I haven't corresponded with the company, so I don't know if Customer Service is their problem. With each order placed, the packets were shipped and received within 3 business days. Others may have problems, but I like these purifiers!
Bottom Line: Yes, I would recommend this to a friend
