Why do you need to keep your hot tub filter cleaner?

Bathers bring all kinds of residue in hot tub water, from dead skin cells to hair and body sweats. Even though hot tub users are usually recommended to shower with soap before a soak, not everyone does.

Personal care products like perfume, lotion, and deodorants gradually build up and cause cloudy water, algae blooms, or the likes.

You’re prone to suffer from different health risks if soaked in an improperly cleaned hot tub. Bumpy and itchy rash is probably one of the most common infections. Some people also have red eyes and irritated nose after soaking in dirty hot tubs.

Aside from sanitizers (chlorine and/or bromine), the filters play an important role in keeping your hot tub clean. They’re also crucial to the overall performance of your tub. By trapping particles and filtering debris, they ensure that your hot tub water is always clean and fresh.

With that said, the filters can be really dirty; therefore, they need to be cleaned regularly so that they can perform their water filtration tasks effectively.

If the filters are not frequently cleaned or properly maintained, they can cause problems on the pump, slow down the heating process, and even strain hot tub parts.

How to clean hot tub filters?

By making a habit of scheduled maintenance for hot tub filters, you can add years to their life. In doing so, hot tub users can also soak with confidence, as you know that your hot tub water is clean.

Depending on how regularly you use the hot tub, there are three ways to clean it, and below is a quick guide.

Quick rinse

If you clean the filter weekly, this will take you only five to ten minutes to prevent hair and other debris from getting trapped in the filters.

You can start by pulling the filters out, then rinse them under a faucet. It’s important to clean between the pleats to clear any clogged residue there.

A garden hose will also make short work of filter maintenance, but you won’t need to use a pressure washer as powerful cleaning tools can tear or break the filters. Wait for the filter to dry before putting it back in.

Chemical rinse

This way of deep cleaning will require a cleaning solution to remove accumulated residue and contaminants, and it should be done monthly.

Simply follow instructions on the packaging, spray it down the filter, and then leave it there for about 15-20 minutes so the cleaner can do its job.

Next, spray it thoroughly to get rid of hair, leaves, or any other substances. It’s best to carefully spread all the pleats apart to ensure that they’re all clean and nothing left in between them.

Once finished this process, you can now submerge it back into your tub for normal use.

Overnight chemical soak

A chemical soak should be done every three or four months when you drain the hot tub water. If you have problems with the skin, remember to choose hot tub chemicals made for sensitive skin.

Besides hot tub soak chemical, you also need a large and clean bucket to accommodate the filter. We would suggest you use a 5-gallon bucket.

First, fill up the bucket with clean water, then follow the directions shown on the bottle to dilute the chemical. Now, gently place your filter in, and make sure that it is completely submerged in the bucket.

The filter needs to sit in this bucket for 24 hours. Even if you’re in a rush, leave it soaking overnight. The next day, rinse the filter thoroughly, then let it dry before reinstalling it back in.

Periodical filter cleaning and maintenance ensure the system can work at its best in collecting dirt and debris. An effective filtration system improves water cleanliness and prolongs the lifespan of hot tub parts.

It features strong yellow tines to hold the slats apart, which allows forceful water streams to get in the nooks and crannies of your filters effectively.

At first glance, you might assume that the water comes out of the yellow comb ends. However, the water shoots out from the blue base between each yellow tooth.

This dual function allows users to gently brush and spray the filters simultaneously. More importantly, even if a tooth is broken, the device is still usable.

How to choose the best hot tub filter cleaners

As there are many types of cleaners that you can find on the market, choosing the most suitable one seems to be tricky. A simple tip is to take into consideration the type of hot tub filter – this will help you narrow down your choice.

If your filter’s fabric is thin, pay extra attention to the ingredients of your cleaner. If it’s a sand filter, then you can just use a regular type of cleaner.

Another tip is to avoid using bleach, as it might damage the pleats fabric and eventually shorten the lifespan of your filters.

By the same logic, dishwashers are too harsh for hot tub filters and can cause damage to the filter’s fabric. Household cleaners may save you some money but can end up leaving foam all over your hot tub water. That said, stick with cleaners made for hot tub filters only.

Never use a power washer or throw your filters in the washing machine. Otherwise, you can run the risk of damaging them just after one wash.

A rub of thumb is keeping a routine cleaning schedule every four weeks, more or less, based on usage and the number of bathers in your family.

But whenever you drain and refill the tub, remember to clean the filters as well. For a monthly cleaning session, you’ll need a cleaner with a special formula for hot tub filters to get rid of stubborn debris.

Keeping a spare filter with you is always a good idea. It allows for an immediate replacement when it’s time to.

Besides, you can also rinse the filter more thoroughly, knowing that you don’t have to rush the cleaning process to install the filter back in right away.

Last but not least, replace the filter after one year of use to ensure its optimal performance.

Frequently Asked Questions about hot tub filter cleaners

What’s the best way to clean a hot tub filter?

It’s best to rinse the filter weekly using the right cleaning tools. If you only clean it monthly or quarterly, opt for a non-bleach cleaning solution.

What can I use to clean my hot tub filters?

For the weekly rinse, there are multiple tools like a flosser or a comb. For the monthly rinse, you’ll need cleaners with a special formula for hot tubs. In doing so, you can avoid damaging the filter fabric surface and leaving foam on the water.

How to clean hot tub filters with vinegar?

When using vinegar to clean the hot tub filter, use a ratio of 1:1 for water and vinegar, then soak the filters in this water mixture and leave it to sit for about two hours.

If your filter hasn’t been cleaned for too long and it’s too grimy, soak it for 24 hours or consider a replacement.

How often to clean a hot tub filter?

Every four weeks.

Still, it will depend on how often you use the hot tub, how many people in your family usually soak in the tub, and whether you usually invite guests over for a hot tub home retreat.

Can I clean my hot tub filter in the washing machine?

No, you can’t. Washing machines clean our clothes by using continuous rolling and tumbling movements of their spin cycles. This process can crack the plastic discs of your hot tub filters.

Besides, your washing machine can be seriously damaged if it has to wash these filters.

Can I use the dishwasher to clean hot tub filters?

The dishwasher is not good to clean your hot tub filter. Dishwashers feature streams of water to clean bowls, dishes, and cutlery, but they can tear up the hot tub filters’ pleats.

Can I run the hot tub with no filter in?

Not really. Running the hot tub with no filter in a very short time wouldn’t do too much harm to the hot tub parts, but more extended use can result in clogging the pump impellers. So it’s best to avoid doing so.

As briefly mentioned above, keeping a spare filter with you would be convenient for quick replacement and cleaning. This extra filter can also save you from awkward situations of running a hot tub without filters in.

Final words

The best hot tub filter cleaner would be the one that meets your needs the most. For the weekly rinse, a well-made and sturdy tool would do its job. For the monthly or quarterly rinse, you’ll need a cleaning solution with a concentrated formula to remove stubborn gunk and grime from your filters.

Regular cleaning is highly recommended, as it ensures that the filters work their best in keeping your hot tub water clean, allowing you to make the most of your time in the soak.
