A pre-filter is for use in a skimmer basket of a hot tub. The pre-filter comprises a stabilizing ring and a shallow shaped cleanable filter permanently secured together. The stabilizing ring is dimensioned for placement within the skimmer basket or on a rim of the skimmer basket. The cleanable filter is made of a water porous synthetic material. Debris is trapped on the shaped cleanable filter as hot tub water is pulled through it on its way to a primary filter apparatus. The pre-filter is easily separated from the skimmer basket, cleaned if desired or simply replaced with a new pre-filter. A paper filter cartridge of the primary filter apparatus in the hot tub has its life significantly increased by use of the pre-filter.
