Tip: Cleaning your filters monthly, can SAVE you money

Like Ben Franklin used to say, "An ounce of provention is worth a pound of cure."

Keeping your filters clean, using a Filter Cleaner on a monthly basis, can help reduce your overall costs of running a spa. How so?

Well, most hot tubs use filter cartridges to remove contaminents from the water. The more "stuff" your filter pulls from the water, the pump has to work harder to pull the water through the dirty filter, get heated, and returned to the spa. Using SpaGuard Filter Cleaner on a regular basis, like once a month, takes the contaminents off the filter and removes oils that can build up.

By removing contaminents, your sanitizers and shocks work much better, as there will be less to be sanitized or oxidized. Potential savings on chemicals and electricity as you wouldn't need to run your pumps as much.

What if I don't clean my filters, what may happen?

Most hot tubs (except HotSpring Spas) have what's called a "bypass". It's a little suction node usually in the footwell area of the hot tub. Water is pulled through a bypass, goes through the pump, then heater, then back into the spa (unfiltered). As it is, only a small portion of the water is actually filtered before it's jetted back into the spa. The dirtier your filter becomes, less water is filtered - just recycled. So you use more chemicals to treat the water, and your pump has to run longer to remove those contaminents.
