Hot Tub Filters

Many hot tub owners know their spa has a filter, but sometimes neglect this important spa component. In order for a paper cartridge filter to do a good job keeping impurities out of the water, it needs to be cleaned regularly.

Spa filters with clogged pores can also cause flow issues and increase heating costs. Over time the hot tub filters can start to break or the caps can crack. It is certainly time for a replacement if the filter no longer reacts to regular cleanings

Consider filters that use quality media. Filter media is the polyester or paper material used as the actual filtration device. Sometimes the media is Microban, which is an anti-bacterial agent and the pleats are blue. The square footage of a hot tub filter refers to the amount of media folded up into pleats. A 25 sq.ft. filter may look exactly the same as a 50 sq.ft. filter, but the latter will have twice as many pleats or twice as much filter media and do a better job of filtering the water.
