Cleaning Your Hot Tub Filter - A Tutorial

If you own a hot tub, you'll know that it's important to have it serviced regularly by a qualified pool contractor. However, you can carry out general cleaning and maintenance tasks yourself. Here's a quick tutorial on how to deep clean your hot tub's water filter.

Why clean out your hot tub filter?

Although your hot tub filter might look clean at first glance, remember that it has been exposed to soap, suntan lotion and natural body oils during the season. All these substances can easily clog the filter and compromise the flow of water through your hot tub.

Every couple of weeks or when the hot tub is in heavy use, it's a good idea to remove the filter and flush it through with fresh water from your garden hose. You should also deep clean your filter on a monthly basis to keep it free from large deposits of debris that a simple flushing might not shift.

Here's how to do it.

What you'll need

concentrated filter cleaner (available from your pool supplies store)
large bucket
hot water
garden hose

How to do it

First of all, turn off all electrical power to the hot tub and take out the filter.
Use your garden hose to flush the filter to get rid of any large bits of surface debris that may be clinging to the pleats.
Next, fill up a bucket with hot water and add concentrated filter cleaner, as per the manufacturer's directions.
Place your filter in the bucket so that it is fully covered. Leave the filter to soak in the solution for at least an hour or for a longer period if the filter is extremely dirty.
Now, remove the filter from the bucket and give it a really good rinse through with your garden hose on a medium pressure. This should get rid of any clinging bits of muck and cleaning product residue, leaving the filter looking like new.
Replace the filter in the hot tub; there's no need to wait until it has dried.

An important point to note here is that you should replace your hot tub filters at least annually. This is because filters lose their efficiency as they age, affecting the performance of your hot tub and possibly compromising its hygiene.

It's a good idea to ask your hot tub services technician to replace the filter during their routine annual service visit so that you don't lose track of when the filter was last replaced.
