Portacool PARPACHWTB00 Hard Water Treatment

These are not super inexpensive, but they do work. I use them in a couple Hessaire evaporative coolers I keep outside for when the weather gets into the 90's or 100's. I live in a city where the water is pretty crummy and quite hard. I noticed a good amount of buildup on the pads when I got the evaporative coolers, but after I started using these within the coolers, the pads have shown minimal buildup. When the weather gets into the 100's, I have home automation which controls a smart outlet that is linked into my Ecobee thermostat for my HVAC system. If it's 88 degrees or higher, I have one of these coolers pointed at the outside condenser, and it runs while the AC is cooling the house. This reduces the head pressure, amp draw of the compressor, and improves the interior cooling performance. I typically only use this setup if it's going to be 100+ for multiple days, but it can certainly put some hours on the EVAP cooler. Again, little to no buildup in almost two summers seasons. I will keep buying these as necessary. I think I've gone through about four packs in two or three years.

Popped it right into the reservoir and started foaming up in suds. Releasing the stuck on calcium deposit from the hard water of Las Vegas. 100% recommended and will be buying again. From reading previous comments unsure of lifespan of each bar so we’ll see. So far so good!

UPDATE: I think the suds are normal! They still emerge slightly upon a fresh fill, but they don't blow bubbles throughout the room anymore. Maybe a reaction to the build-up already present the first go-around? In any event, we've noticed that since we put this in a month ago, our Hessaire evaporative cooler unit is performing excellently, not getting less strong over time as seemed to happen without something like this Portacool treatment stuff. Like another reviewer, after dropping this in my tank on a fresh fill, I proceeded to get suds built up. They started coming out as bubbles from the vent but it didn't escalate to chaos: the bubbles stayed small and it didn't become a boilover situation. The sud buildup on top of the water line was about half an inch at the peak; by end of use tonight, suds were about a quarter inch. I will keep an eye on this and modify my review appropriately to see if this becomes a repeat problem. It's only been one day of use, and it's not clear proof, but after using this, we achieved 1°F more cooling than we usually get. I think the scale buildup visible on the inside of the fill meter has cleared up too.

They are a solid bar inside a cloth sleve and they colo the water slightly. They don't desolve so you aren't sure when they are used up. I gage by the color getting much lighter. They eliminate the constant adding & measuring of liquids. So much easier! Seem to work ok but not a cure-all. There is still some buildup but it did help. Yes, much more sane & easier than liquid with less storage space. Yes, I'll get more for next years swamp cooler.

Using in a window evaporative cooler. Amazing! Not only minimizes new mineral deposits but also removed some preexisting mineral deposits.

This product works great! I've had my swamp cooler for a about three month now and every month it has been a huge chore to clean the scale build up in the cooler due to our very hard water here in Phoenix AZ. I purchase this product about a month ago and this last time I had to clean my cooler the process went so much faster. There was a lot less buildup - a notable difference. I will continue to use these water treatment stick next summer.

It seems to do a fairly decent job at breaking up some existing build up or preventing more to develop. Dont skip out on deep cleaning your unit. Vinegar washing is still king. There is little to no difference in cooling pad performance and these little blue guys tend to sud up an evaporative cooler. Sometimes these suds can spill out from sides and create a leak.

I use this product in my evaporative/swamp cooler in my shop. Since I have hard water using this product is a must to prevent water scale buildup in my coolers media panels. Super simple to use. Drop one packet in the water tank once per month while using your cooler and that’s it. I have purchased from my local Port-a-cool dealer in the past, but for the last year or so they have not been able to stock this item. The price is right, and it’s well worth the money instead of having to descale and possibly damage your media panels.

Apenas le coloque esta cosa y en un rato llenó de espuma el depósito de agua de mi enfriador evaporativo haciendo que arroje espuma por todos lados junto con el aire. Me vi obligado a abrirlo para retirar el producto y hacerle una limpieza para acabar con ese problema. Completamente inútil
