Our filters use quality Reemay filter media (Outpost, Filbur) or spunbound media (Pleatco) in their design for the best filtration quality.  Save money on quality spa filters made with Reemay media by checking out the Filter Outpost line of filter cartridges.  There may be one available for your spa model.

Most manufacturers recommend changing the spa filter cartridge every year.  Get 2 and rotate them - so one can be cleaned or soaked in an overnight filter solution while the other one is on active filtration duty. 

Keep your filter clean by rinsing it off regularly. Use either an overnight filter soak or a filter spray once a month to maintain clean pores and the best filtration for your hot tub.  Once a filter becomes dark grey or the fibers and pleats start to lose their shape, then it is time to change the filter.

Keeping a clean and functioning filter in your spa will keep your family safe from bacteria and other contaminants, help you save on spa chemicals, and protect your expensive equipment.  If you are seeing a 'flo' error on your control panel, chances are it is caused by a dirty filter preventing proper circulation.

Lessen the load on the filter by using a PREFILTER with every fresh re-fill.
