Why Pool Filters Matter — and How Pool Depo Helps

A proper filter removes debris and oils so your sanitizer can do its job — keeping water healthy and swim-ready. DIY homeowners and small service providers need compatibility, straightforward installation, and parts that last. Pool Depo simplifies the process with clear fitment details, live chat support, and a large in-stock selection for quick shipping.

• Broad compatibility: Parts and cartridges that fit most residential systems (Pentair, Hayward-compatible Unicel parts, Aquamax).
• Time & cost savings: Quick cartridge swaps and long-life options reduce service calls and repeat purchases.
• Fast shipping: Ready-to-ship inventory so pools return to service quickly.

Frequently asked questions

What size filter do I need?

Match your pump's GPM and pool volume to the filter's rated flow and square footage. Cartridge options range widely — contact support with model and pool size for a recommendation.

Can I install this myself or do I need a technician?

Most cartridge replacements and sand filters are DIY-friendly. DE systems require more steps. Product pages include instructions — reach out to live chat if you want step-by-step help.
