A Pursell Manufacturing Product
Polish the Water.
Filter Boost media can supercharge your sand filter to as low as 2-micron filtration — or safely replaces D.E. with 100% biodegradable plant fibers. Silica free and safe. Cleaner, safer, easier.
Why Filter Boost
A Better Filter Media in Every Way
Diatomaceous Earth has been the industry standard for decades. Filter Boost improves on it in every measurable category.
| Category | Filter Boost | Diatomaceous Earth |
|---|---|---|
| Material | 100% biodegradable plant fibers | Crushed fossilized algae (silica) |
| Filtration | ~2-3 micron particle capture | ~3–5 micron particle capture |
| Safety | Silica free & safe — no protective gear needed | Crystalline silica — respiratory hazard, requires mask & gloves |
| Filter Compatibility | Sand, D.E., and cartridge filters | D.E. filters only |
| Environmental | Biodegradable and eco-friendly | Non-biodegradable mineral waste |
| Amount Needed | 1 lb Filter Boost replaces 8 lbs of D.E. — use just 1/4 to 1/3 the amount | Full D.E. charge required every cycle |
| Chemical Demand | Reduces chemical needs — saves money | Standard chemical demand |
| What It Removes | Algae spores, fine pollen, dust, sunscreen residue | Larger particles only |
Pure Cellulose. Remarkably Effective.
Filter Boost is made from ultra-fine natural cellulose plant fibers. Unlike Diatomaceous Earth, it contains zero crystalline silica — completely safe to handle without protective gear. Removes algae spores, fine pollen, dust, and sunscreen residue.
1 lb of Filter Boost replaces 8 lbs of D.E. For a 24 sq. ft. filter: use 3 scoops (3 cups).
Designed for commercial and high-volume pool systems. Same great performance at scale.
Simple to Use
Three Steps to Cleaner Water
Pour
Make a slurry or sprinkle 1 scoop at a time into the skimmer while the pool pump is running.
Filter
Filter Boost coats your filter media and captures particles down to 2 microns — algae spores, pollen, dust, and more.
Backwash & Recharge
Backwash when pressure rises ~10 psi above clean setting, then recharge with Filter Boost as needed.
