When it comes to settling on the best pool filter in Central Coast, there are many factors that you need to consider, including the pool size, seasonal climate conditions, bather load, frequency of use, and whether the pool has a screen enclosure among other factors.

However, before discussing the most common types of filters that many homeowners consider for their pools on Central Coast, it is important to know what a pool filter is. A pool filter is a system that is plumbed into your pool’s plumbing network so that as the water passes through it, dirt and debris are trapped inside. This ensures that water going into your pool is clean.

Common Types of Pool Filters

1. Cartridge Filters

These are cylindrical filters with pleated filter materials to maximize the square footage of the filters. They can capture debris, which are as small as 10-15 microns. They are easiest to maintain as they need to be replaced only once a year. The cost of replacement will, however, vary based on the size and square footage of the cartridge.

2. Sand Filters

These types of pool filters extract impurities or debris from your pool water using sand. Once the debris builds up, you will need to backwash the filter—this involves running water through the filter in the reverse direction. Sand filters can filter debris of up 20-40 microns, so they are not as effective as cartridge filters. Nonetheless, they are easy to maintain as what you need to do is to just backwash them once every several weeks. It is recommended that you change the sand once every 3-4 years. These types of filters are also heavy and bulky.

3. Diatomaceous Earth (or DE) Filters

These filters have grids that are coated with DE powder, filter media which feature fossilized exoskeletons of tiny diatoms. They are backwashed just like sand filters, but besides backwashing, the filters also need fresh DE powder to be added periodically. DE filters can trap debris that are as small as 2-5 microns.

So which pool filter should you opt for? Well, your budget and personal preferences should dictate this. If you want a filter that will clean your pool for long with little to no problems, you should opt for sand filters. They are also inexpensive, and that’s why they are often included as part of a basic pool package in Central Coast. If you want something premium and maintenance-friendly, cartridge filters are great options. You should also note that there are new cartridge filter elements that are compatible with DE filters.
