What Our Customers Have to Say

Yvonne Johnson 1 day ago
These filters work great for my hot tub! Easy to clean. I usually just spray them off with the hose at least a couple times a month. It helps to keep them longer. They can last 6 months + depending on usage of hot tub and sun tan lotion, body lotion, perfume, etc. I wait until they are on sale and got them for a good price!!

Frequently Asked Questions

How do I know when it's time to clean my pool cartridge filter?

For pools, most cartridge filter systems include a pressure gauge on the top of the filter tank. When the cartridge has become loaded with debris, the pressure in the tank rises. When the pressure gauge reads about ten pounds-per-square-inch (PSI) over normal, it's time to clean the cartridge or cartridges.

How do I know when it's time to clean the filter in my hot tub or spa?

It's recommended to clean and inspect your hot tub / spa filters every 2 weeks. At 2 weeks, give the filter a quick rinse. At 3 months perform a more thorough cleaning - agitating the filter in a bucket of water with your favorite cleaning solution and allow it to soak overnight. Each year purchase new filters and repeat the processes above.

Can pool and spa filters be washed?

Yes, the media in most pool filters is constructed from fabric and is washable. Once removed, pool and spa filters can be rinsed with a garden hose. We sell a cleaning tool which makes this process much easier. There is a point where the filters should be replaced. When you see signs of frayed fabric or damage - it's best to purchase new filters.

What's the difference between a sand and cartridge filter?

Sand filters can remove particles down to 20-40 microns in size. We do not sell sand filters. Rather, we sell replacement cartridge filters, which are more efficient than sand filters - removing particles down to 10-20 microns in size. Cartridge filter systems are generally easier to service than sand filter systems.

How do I know what pool or spa filter to buy?

Identifying the correct pool or spa filter can be tricky - as there are often no identifying marks on the filter itself. To find your filter, you can type the model number of your filter system into the search box on our site. You can also enter the filer dimensions (diameter and length) in our filter finder utility.
