AC Safe Tablets-30 Cleans scum in Drain Pans and Humidifiers, 30 Count (Pack of 1), Blue

Saves us a lot of heartache. Aircons in our apartment are old and overflow easily, even after they were serviced. Great product

I had a doubt about them, but after the test I can say it is very safety to use it.

It works well, I have already order it again

Fantastic product for our furnace humidifier. It cleaned it up immediately. Super product

My splits would clog with the cheap giant container tablets and they always smell. It always gave the cool return an odor. It’s worth extra money not to have condensation overflow drip on the floor. I use 4 tablets per week per split to keep the condensation flowing

Best on the market

Used in our window air conditioner, works great to control odors

This is my second purchase of these tabs which I use to effectively reduce the musty smell that comes from my two overhead mini-split heat pump heads. Every 10 days or so they start smelling bad when the air flow is slow or they have dried out - active coolers with regular condensation flow do not smell much, only smelly after they have been off overnight or being run without the cooling action. Odor goes away entirely during the winter heating period but returns with moisture condensation during cooling mode. I have not tried other brands which may work better or longer, or may be a waste of money - I chose the US made brand. Shelling out $30 or more for a different brand in a large bottle may save you money, or they may not work as well for you as this brand. Its a gamble. The tabs won't start working until your cooling head is actively dripping condensate onto the tablets, they have to dissolve slowly and flow along the drain trough to work. They are not perfumed. I have never had a clogged drain hose. Place these on the opposite end of the condensate trough from the drain so the active ingredient flows over the odor causing bacteria first.
