  • No more clogs
Size: 200 Count (Pack of 1)
My HVAC guy recommended I buy these. I place them in my unit monthly and have no problems. Well worth the money and gives a fresh sent when you place them in the water pan. I have been using these since June 2025 after l having routine service. We had a blockage in March 2025 even after cleaning and using a shop vac to suck out the gunk. These tablets definitely work better than the white vinegar cleaning method. I still hook up my shop vac twice a year as part of my normal preventative maintenance. ... show more

  • Easy Preventative Maintenance for Your AC Drain Line
Size: 200 Count (Pack of 1)
Living in Florida, keeping our A/C running properly year-round is a priority, so I like doing simple preventative maintenance whenever I can. These drain line treatment tablets make that process incredibly easy. The tablets are pre-measured, so there's no mess or guessing. I simply place one in the drain line as directed, and it slowly dissolves to help reduce the buildup of algae, slime, and other debris that can clog the condensate drain over time. Since using them, my drain line has stayed clear and I've avoided the water backups and musty odors that can happen when the line starts to clog. One bottle lasts a long time with 200 tablets, making it a great value compared to paying for an HVAC service call that could have been prevented with routine maintenance. Of course, these aren't a substitute for regular professional HVAC maintenance, but they're an inexpensive and simple way to help keep your system running smoothly between service visits. If you live in a humid climate where algae buildup is common, these are definitely worth keeping on hand. They've become part of my regular home maintenance routine, and I'll continue buying them. ... show more

  • Really effective. Completely solved my issues.
Size: 200 Count (Pack of 1)
Work great. Used to have problems with algae buildup that clogged the drain lines and caused a weird smell. These cleared it up really quickly and have prevented it from happening again. Also really easy to use. Just drop one tablet so it lands in the drain pan every so often and you have nothing to worry about. ... show more

  • Easy HVAC Maintenance That Works
Size: 200 Count (Pack of 1)
I’ve been using these Flow Treat Tabs for my HVAC drain line, and they’ve worked well overall. The tablets are easy to drop into the drain line and seem to help keep it clear while reducing musty odors. It’s a simple maintenance step that gives me peace of mind. The only reason I’m giving 4 stars instead of 5 is that the tablets dissolve a little more slowly than I expected, and the instructions could be a bit more detailed for first-time users. That said, they do the job, and I would purchase them again as part of my regular HVAC maintenance routine. ... show more

  • Easy Maintenance for HVAC Condensate Pumps
Size: 200 Count (Pack of 1)
I've been using these tablets in my condensate pump for several months now, and they've worked great. Since adding them, I haven't had any issues with mildew or sludge building up in the pump or the discharge line. It's been a simple way to keep the system clean and running smoothly. Definitely a product I'll keep using. ... show more

These are amazing! Used them in three minisplit heads, dehumidifier condensate pumps and central air. Cleaned up the lines to the sewer almost good as new in a couple of days.
