Unicel PG-1906 DE Filter Grid – 72 Sq Ft (Partial / Small), 36″ Length
The Unicel PG-1906 is a replacement diatomaceous earth (DE) filter grid used in select vertical-grid DE filters that use a partial / small grid. This grid provides 72 square feet of effective filtration area and is designed to restore proper filtration performance when an existing grid is torn, frayed, or allowing DE powder back into the pool.

- 72 sq ft filtration area
- Helps improve water clarity by capturing fine debris when used with DE powder
- Replaces worn or torn grids to help prevent DE blowing back into the pool
- Durable fabric/media construction designed for repeated cleaning cycles

Installation Notes
- Always shut off power and relieve filter pressure before opening the tank.
- Inspect the full grid set—if one grid failed, others may be near end-of-life.
- Check the manifold, standpipe o-ring, and air relief parts for cracks or wear while the filter is open.
- After reassembly, recharge the filter with the correct amount of DE per your filter model and size.

Maintenance Tips
- Backwash/clean when pressure rises about 8–10 PSI over your clean starting pressure.
- Open and inspect grids at least once per season; small tears can quickly turn into major DE blow-back.
- Rinse grids thoroughly after cleaning and avoid using stiff brushes that can damage the fabric.
- Keep water chemistry balanced—extreme pH and high calcium can shorten grid life and increase scaling.
