Frequently Asked Questions
How often should I replace my Hydropool® filter?
Hydropool® recommends replacing filter cartridges every 12-18 months depending on usage. However, if you notice reduced water flow, cloudy water, or visible wear on the filter media, replace it sooner. Regular cleaning every 4-6 weeks extends filter life.
Are these filters compatible with Hydropool® self-cleaning systems?
Yes! All Hydropool® filters in our collection are designed to work with both self-cleaning and traditional Hydropool® models. The self-cleaning system relies on proper filtration, so using genuine or high-quality compatible filters is essential.
What's the difference between Hydropool® and other hot tub filters?
Hydropool® filters are engineered specifically for their pressurized self-cleaning filtration system. They feature durable construction, optimal pleat spacing, and materials that withstand the unique demands of Hydropool®'s cleaning cycles.
Can I use aftermarket parts on my Hydropool® spa?
While genuine Hydropool® parts are always recommended, high-quality compatible alternatives can work well. At Hot Tub Things, we only carry products that meet strict quality standards and are verified for Hydropool® compatibility.
How do I know which Hydropool® filter I need?
Check your owner's manual for the filter part number, or measure your current filter (length, diameter, and thread type). Our customer service team can also help you identify the correct filter for your specific Hydropool® model.
Do Hydropool® filters work with other hot tub brands?
Some Hydropool® filters may be compatible with other brands if the dimensions and specifications match, but we recommend using filters specifically designed for your hot tub manufacturer to ensure optimal performance.
