5 Essential Types of Pool Filter Cleaning You Need to Know
A clean and well-maintained pool filter is key to keeping your pool water clear and safe for swimming. It helps trap dirt, debris, and impurities, making sure your pool stays inviting all season long. To keep your pool sparkling, it’s important to take good care of your filter. In this guide, we’ll show you the basics of pool filter care, with helpful tips to keep your filter working at its best.
1. Understanding the Types of Pool Filters
There are three main types of pool filters: sand filters, cartridge filters, and diatomaceous earth (DE) filters. Knowing which type you have is key to effective pool filter cleaning.
Sand Filters: These are cleaned primarily by backwashing. Keep an eye on the pressure gauge and backwash when the pressure rises by about 8-10 psi.
Cartridge Filters: For cartridge filters, remove the cartridges and hose them down to clean them. Be sure to clean them when the pressure gauge shows an increase in pressure.
DE Filters: DE filters offer the finest filtration and require both periodic backwashing and refilling with DE powder to keep them working at their best.
2. Check the Pressure Gauge
All pool filters come with pressure gauges that help you monitor their condition. As your filter traps dirt and debris, the pressure inside the tank rises. This increase in pressure is a clear sign that the filter needs attention.
To know how often to clean your pool filter, you should regularly check the pressure gauge. If the pressure rises by 8-10 psi above the normal operating level, it's time to clean the filter. Keeping an eye on this pressure reading ensures that your filter continues to work effectively and helps prevent any long-term damage to the system.

3. Regular Backwashing
Backwashing is an important maintenance task for both sand and DE (diatomaceous earth) filters. This process helps keep your filter working effectively by flushing out dirt, debris, and contaminants that get trapped inside the filter. During backwashing, the flow of water is reversed, pushing the collected particles out of the filter and into the waste drain. This helps to clear the filter media, ensuring it continues to provide clean, clear water for your pool.
To know when it’s time to backwash, you can rely on two key indicators. First, check the manufacturer's recommendations for how often to perform this task. In general, it’s recommended to backwash your filter when the pressure gauge shows an increase of 8-10 psi above the normal operating pressure. Regular backwashing is crucial for maintaining the filter's efficiency and preventing clogging, which can lead to poor filtration and higher energy costs. Always follow the specific guidelines for your filter type to ensure optimal performance.
4. Keep the Pool Area Clean
To help keep your pool filter in top condition, it's important to prevent excessive debris from entering the pool in the first place. Start by regularly cleaning the pool area, including removing leaves, grass, twigs, and any other debris that may accumulate. Make it a habit to skim the surface of the water daily and empty the skimmer baskets frequently. This will prevent debris from sinking to the bottom or getting caught in the filter, reducing the strain on the system. By keeping the pool area clean and minimizing the amount of debris in the water, you’ll help your filter run more efficiently and extend its lifespan, saving you time and money on repairs or replacements in the future.
5. Deep Clean Annually
In addition to regular maintenance, it's a good idea to perform a deep clean of your pool filter at least once a year. This process involves taking apart the filter and cleaning each component thoroughly to ensure it stays in optimal working condition. To do this, carefully follow the manufacturer's instructions for disassembling the filter. Each filter type may have specific steps for removing and cleaning the parts. It’s important to clean all areas of the filter, including the cartridges, grids, or sand, depending on your system.
A deep clean helps remove any stubborn debris or buildup that regular maintenance might miss, ensuring that your filter runs smoothly and efficiently throughout the season. Doing this yearly will help extend the life of your filter and keep your pool water crystal clear.
