You can have perfectly balanced chemicals and brush your pool every single day, but if your filter is dirty, your water will never be truly clear. The filter is the kidney of your pool system, working tirelessly to remove microscopic dirt, body oils, sunscreen, and dead algae from the water.
Over time, this debris builds up, restricting water flow and crippling your system's efficiency.
Types of Pool Filters
- Cartridge Filters: Use large, pleated paper-like cartridges to trap dirt.
- DE (Diatomaceous Earth) Filters: Use a fine powder made of crushed fossils coating internal grids to provide the highest level of filtration.
- Sand Filters: Use a large tank of special silica sand to trap debris.
Why You Can't Just "Backwash" Forever
While backwashing (reversing the water flow to flush out dirt) is a standard maintenance task for DE and sand filters, it is not a substitute for a deep clean. Backwashing only removes about 70-80% of the loose dirt. Over months of use, heavy oils and scale bake themselves into the filter media.
The AV Pool Pros Deep Clean
We recommend a professional filter tear-down and deep clean every 3 to 6 months (depending on pool usage and filter size). Our process includes:
- Complete Disassembly: We open the tank and carefully remove all cartridges or DE grids.
- Degreasing and Descaling: We soak the elements in a specialized cleaning solution that eats away body oils, sunscreen, and calcium scale that standard water pressure cannot remove.
- High-Pressure Rinse: We meticulously wash every pleat and grid.
- O-Ring Lubrication: We inspect and lubricate the main tank o-ring to ensure a perfect, leak-free seal upon reassembly.
- Recharging (DE only): We add the precise amount of fresh DE powder back into the system.
A clean filter lowers the strain on your pump, improves water clarity, and ensures your pool is sanitary. Book your filter cleaning with AV Pool Pros today.
