Best Sand Filter For Hot Tub Buying Guide
When you are in your hot tub, the last thing you want to deal with is excessive noise coming from your filter.
A lot of filters are designed to be quiet with this in mind. Look out for those listed as low noise levels to ensure you are getting a quiet filter that won’t disturb your relaxing time in your hot tub!
The XtremepowerUS filter we mentioned earlier is the best we can find for a super quiet operation!
When opting for a sand filter for your hot tub, it is worth considering the filter’s size.
We usually work out what size we need based on the gallons of water the filter can process per hour, so it’s worth knowing the capacity of your hot tub before purchasing!
Buying a filter too small will mean it will take a long time to clean the hot tub, and you run the risk that you will overwhelm the filter, not good!
On the other hand, a pump with a massive capacity will use unnecessary electricity and take up more space than you need it to!
As many sand filters are designed for pools, it’s worth searching for mini sand filters to find the best size for your hot tub!
Check your capacity before you purchase and get the right size for you and your needs.
The price of a sand filter can vary, so it is crucial to have a clear budget in mind and stick to it as closely as possible.
Despite the varying price, you don’t need to spend a fortune to get a good quality sand filter for your hot tub.
Be sure to consider the essential factors when setting your budget to be tailored to your filter needs and your bank balance!
Generally, sand hot tub filters are the cheapest hot tub filters you can purchase, but typically only last 5-7 years before needing replacement, something to consider when setting your budget.
