For water that literally sparkles
Diatomaceous earth (D.E. as it is referred in the pool biz) filtering removes particles that you can’t even see with the naked eye. However, enough of those “unseeable” particles can have an adverse effect on water clarity. 4000 Series™ filters removes these contaminants, so your water truly sparkles. Not only do the 4000 series filter offer exceptional filtration, Pentair SMBW 4000 Series D.E. filters are built for that long haul, dependable performance and easy maintenance.
Features include:
- Unique Spiro-Mite curved grid design ensures an even flow and uniform distribution of D.E. for optimum filtration efficiency and longer periods between cleanings.
- Corrosion-resistant 20" diameter fiberglass filter tank is strong, durable and made to last for years.
- Filter’s refined internal design minimizes flow restrictions so that the least amount of pumping power produces the maximum required flow rates—for lower utility costs.
- Exclusive clamp ring design is safe, strong and reliable—permits quick and easy access to internal component.
