Cartridge filter vs sand filter for hot tub use comes down to the system already in place: a cartridge filter is a replaceable unit for the tub’s filter system, while a sand filter is a separate vessel that filters through sand media. For the inflatable hot tubs in this guide, the cartridge side is the match, and the gear below is all cartridge-side, with no sand filter example listed.

Cartridge filter vs sand filter for hot tub: which side fits
The choice follows the tub. A tub built for Type VI cartridges takes a Type VI cartridge, and a tub built for a sand vessel takes sand media. The listings here cover only the cartridge side, so this guide states no sand figures at all.
Cartridge filters, as listed here
The cartridge picks are Type VI units for inflatable hot tubs. The Macaberry listing states installation inside the filter pump and dirt captured as it passes through the system. The Bestway listing states paper folds that lift out for spraying between the folds with a garden hose, while the Macaberry and Volca listings state dacron fabric that collects hair, leaves, dust, sediment, and sand. Sizes stated are 4.1 by 3.1 inches for two picks and 4.2 by 3.1 inches for the genuine Bestway pick, and pack sizes are 2, 6, and 12 cartridges.
Cleaning and replacement are part of the routine. The Bestway listing states cleaning or replacing every 2 weeks, the Macaberry listing states replacing every 2 weeks during heavy usage, and the Volca listing states replacing every few weeks if used heavily. The cleaner spray works in 5 minutes per its listing.
Sand filters, and what is missing here
No sand filter example is listed below, so this guide makes no claim about sand media size, sand lifespan, or sand system sizing. A reader whose system is built for sand should check that system’s own figures before ordering, since none of the cartridge figures here transfer to a sand vessel. The cleaner spray is also cartridge-only, with no sand use stated.
The gear
Score notes
The Chill Score weighs performance, build, value, safety where it applies, and warranty. Safety and warranty are zero for all four picks, since no listing states a safety certification or a concrete warranty term.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Bestway Type VI 2-Pack | 9.6 | 30 | 21 | 20 | n/a | 0 |
| Macaberry VI 12-Pack | 9.6 | 29 | 20 | 21 | n/a | 0 |
| Volca Type VI 6-Pack | 9.6 | 28 | 20 | 20 | n/a | 0 |
| Black Diamond Cleaner | 9.5 | 28 | 20 | 19 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Common questions
Can a cartridge filter fit a sand filter system?
No. A cartridge fits the system it was made for, and the cartridge picks here fit Type VI systems on inflatable hot tubs. Check whether the system takes cartridges or sand media before ordering.
How often should a cartridge be cleaned or replaced?
It depends on the listing. The Bestway listing states cleaning or replacing every 2 weeks, the Macaberry listing states replacing every 2 weeks during heavy usage, and the Volca listing states replacing every few weeks if used heavily.
What does the filter cleaner do?
The cleaner spray is for pleated cartridges: spray it on the filter surfaces, wait 5 minutes, rinse with a strong water stream, and reinstall, per the listing. It is a cleaner, not a filter, so it does not replace a cartridge.
Do any of these picks include a sand filter?
No. All four picks are cartridge-side gear: three Type VI cartridge packs and one spray cleaner for pleated cartridges.
