When it comes to reliable pool filtration, sand filters remain one of the most trusted and widely installed options in the industry. One of the most popular models we install is the Hayward S244T sand filter—known for its durability, simplicity, and consistent performance.

But not all sand filters are created equal. What you put inside the filter—traditional sand or glass media—plays a major role in maintenance, longevity, and water quality.

Let’s break it down.

The Hayward S244T Sand Filter: A Proven Workhorse

The Hayward S244T is a high-capacity sand filter designed to handle residential inground pools efficiently. It uses a multiport valve system that makes backwashing and maintenance straightforward, and it pairs well with both standard sand and glass filter media.

For pool owners who want dependable filtration without overly complex systems, this filter checks all the boxes.

Sand vs. Glass Media: What’s the Difference?

Traditional Pool Filter Sand

Pros

• Lower upfront cost
• Readily available
• Proven and reliable
• Easy to replace during routine maintenance

Maintenance & Lifespan

• Typically needs to be changed every 6–8 years
• Requires more frequent backwashing, especially during peak swim season
• Over time, sand particles become rounded and compacted, reducing filtration efficiency

Sand filters generally trap debris down to about 20–40 microns, which works well for most residential pools when paired with good water chemistry.

Glass Filter Media

Pros

• Filters smaller particles (often 10–15 microns)
• More efficient water flow
• Less prone to clumping or channeling
• Requires less frequent backwashing

Maintenance & Lifespan

• Lasts 10+ years, often much longer than traditional sand
• Backwashing is needed less often, which saves water and chemicals
• Higher upfront cost, but lower long-term maintenance needs

Glass media is especially appealing for homeowners who want clearer water, reduced maintenance, and long-term efficiency.

Backwashing: Sand vs. Glass

Backwashing is essential for keeping your filter working properly, but frequency varies depending on the media used.

• Sand Media
  • Backwash when pressure rises 8–10 PSI above normal
  • Typically required more often, especially with heavy use or debris
  • Uses more water over time
• Glass Media
  • Backwashing is still necessary, but less frequent
  • Media resists compaction, so it stays cleaner longer
  • Uses less water overall

Why Pool Chemistry Matters More Than You Think

No matter which media you choose, proper pool chemistry plays a huge role in how long your filter media lasts and how well it performs.

Poor water balance can lead to:

• Calcium buildup inside the filter
• Oils and debris coating media
• Reduced filtration efficiency
• Shortened media lifespan

Maintaining balanced pH, calcium hardness, sanitizer levels, and regular brushing/backwashing helps both sand and glass media perform at their best—and helps you avoid premature replacements.

Which Option Is Right for You?

• Choose Sand Media if you want a lower upfront cost and are comfortable with standard maintenance intervals.
• Choose Glass Media if you want longer media life, improved filtration, and less frequent backwashing.

Both options work extremely well when properly installed, maintained, and paired with good water chemistry.

Our Take as Pool Professionals

The Hayward S244T sand filter is an excellent choice for many inground pool installations. Whether you opt for traditional sand or upgrade to glass media, the key is proper installation, correct sizing, and ongoing maintenance.
