How the AquaCrystal Sand Filter Works

The AquaCrystal Swimming Pool Sand Filter operates through a multi-stage filtration process, ensuring your pool water stays balanced and free from impurities.

Filtration Process:

  1. Water Intake – Pool water is drawn into the filter tank.
  2. Sand Filtration – Water passes through graded silica sand, which captures dirt, debris, and oils.
  3. Clean Water Return – Filtered water is circulated back into the pool, ensuring a fresh and clear swimming experience.

This continuous process ensures efficient water purification with minimal effort.


How Does a Pool Sand Filter Compare to Other Pool Filters?

Selecting the best swimming pool filtration system depends on maintenance, filtration capacity, and cost. Here’s how a sand filter compares to other pool filtration systems:

Sand Filters:

  • Requires backwashing every few weeks and sand replacement every 3–5 years.
  • Captures particles as small as 20–40 microns.
  • Affordable with low operating costs.

Cartridge Filters:

  • Needs monthly cleaning and filter replacements every 1–2 years.
  • Captures finer particles, between 10–15 microns.
  • Higher maintenance and replacement costs.

DE (Diatomaceous Earth) Filters:

  • Filters particles as small as 3–5 microns, providing the highest filtration quality.
  • Requires regular DE powder refilling and frequent backwashing.
  • More expensive and requires more effort to maintain.

For most pool owners, the AquaCrystal Pool Sand Filter provides the best balance of cost, efficiency, and ease of use.
