The 411 on Hot Tub Filter
Pool Supply Unlimited carries a great selection of top load and inline hot tub filter housing from leading manufacturers like Pentair, Waterco, and Waterway. We carry two types of hot tub filter housing, top-loading and inline.
 
Top load filter makes it easy to remove the lid from the top and peer into the canister to check the hot tub cartridge and check for cracks. This is different from an inline filter, which is a separate filter assembly attached directly to the piping before the heater.
 
Hot Tub Filter Housing Maintenance & Replacement
Just like pools, spas have their own maintenance requirements to keep safe, as well as more enjoyable. One of these maintenance requirements is checking that your hot tub filter is in good shape. The general consensus is that a hot tub filter only needs to be replaced if a major crack or leak is present that cannot be fixed.
 
Some common issues that arise in hot tub filters are cracks, leaking gaskets, and leaking o-rings. If a top load filter lid is leaking, a faulty o-ring is likely to blame. If a crack exists between the shell and housing, it is possible to mend the crack with silicone, sealant, or underwater epoxy. However, if there is a crack in the housing and it cannot be sealed, your hot tub filter needs to be replaced.
 
Choosing the Right Hot Tub Filter Housing Replacement
Choosing the right hot tub filter housing replacement comes down to matching the dimensions from your existing filter to the new filter you'd like to replace it with, including the length. All you'll need to do is find the model number on the hot tub filter you'd like to replace to get the exact dimensions you need to match.
