(30) Tablets - HYDREX HVAC Drain Pan Tablets/Tabs, Compatible Replacement for PT-151 / PT-200 / PT-217 ((30)HYDREX TABS_v2)

Clean drain pan.

These are a little big so you have to place them just right if you're putting them in the piping, but so far we haven't had any issues. We'll see!

Usual blue tabs last quite some time. These lasted maybe a day? Not sure if they are a good buy or not? Riding down the middle at current.

Put two tablets in condensate drain of my HVAC. Condensate pipe even after two weeks still has a light scum on surface of water. May have to just go back to white vinegar flush of the condensate line every month.

I figured the Seller buys these in bulk and re-package into smaller quantities as they came in a totally unmarked plastic bag. Delivery was fairly quick. These work have no negatives about performance. I'm puzzled about the "Scent" star rating. These have no scent so I can't do more than just middle of 5 stars. Value ? Compared to Pan Tabs from Home centers yes it's a better value. Next time i'll purchase in bulk.
