Which Filter is Best?

Ah, the million-dollar question: which of the many pool filters is best for your backyard paradise? The answer depends on your lifestyle, your pool habits, and how much time you want to spend on maintenance.

Let’s start with the classics.

Sand Filters

Once upon a time, sand filters were the go-to for every backyard pool. They’re simple, tough, and they get the job done. These filters can trap particles as small as 20 microns, which is great, but not quite high-def clarity. They’re reliable workhorses, but compared to modern systems, they’re a little behind the times, like your old flip phone that still technically works but doesn’t stream movies or send emojis.

Cartridge Filters

Now we’re getting fancy. Cartridge filters are the modern favorite for those who want cleaner water with less hassle. They filter out particles as small as 5 microns. That’s smaller than a single speck of dust you’d never even notice. These filters don’t need backwashing, which means they save water and energy. Plus, they’re easier to clean. You just pop them out, give them a rinse, and you’re good to go. If you like low maintenance and high performance, cartridge filters might just be your pool’s new best friend.

Diatomaceous Earth (D.E.) Filters

If crystal-clear water makes your heart sing, D.E. filters are where it’s at. They can catch particles as tiny as 3 microns, which is cleaner than most bottled water. To put that into perspective, a red blood cell is about 6 to 8 microns wide. So yes, your pool will be cleaner than a hospital floor. D.E. filters are perfect for perfectionists, those who like their water sparkling and flawless. Just be warned, they need a little more upkeep, but for that level of clarity, it’s totally worth it.

The Science of Clean Water

Having a filter that allows water to flow efficiently isn’t just about clean water; it’s about saving money, too. A properly sized filter means your pump doesn’t have to work overtime. That translates to shorter run times, less electricity use, and a smaller power bill. And who doesn’t like saving a few bucks?

When you let us help you choose the right size and type of filter, you’re not just getting clear water. You’re getting peace of mind knowing your system is running smoothly and efficiently. Because nothing ruins a pool day faster than murky water and a humming pump that sounds like it’s begging for retirement.

When Is It Time to Repair a Filter?

We get this question a lot, and the answer usually starts with, “When something looks off.” If you notice sand in the water or little piles of it on the pool floor even after vacuuming, that’s a red flag. You might have a tear in your filter screen or cartridge element. Cartridge elements usually last around a year, and D.E. grids can go for several years if treated right.

Other signs? If your PSI gauge hasn’t been replaced in a couple of years, it’s time. It’s like your car’s dashboard; you don’t want to ignore what it’s trying to tell you. Above-ground leaks or constant air bubbles in the water returns often trace back to the unions at the filter. And if you’re cleaning your filter every single week, something’s up. Either your cartridge needs replacing, or your filter is undersized for your pool’s workload.

Basically, if your filter feels like a high-maintenance relationship, it might be time for a change.

Pool Filter Maintenance Tips

We know maintenance isn’t the most glamorous part of pool ownership, but it’s the key to keeping your water clean and your system happy. A little regular care goes a long way. Here are our top pro tips:

  • Keep an eye on your pressure gauge. A rise of 8 to 10 PSI usually means it’s time to clean your filter.
  • Backwash your sand or D.E. filter when needed, but don’t overdo it; too much backwashing wastes water.
  • Clean your cartridge filters regularly, but be gentle. You don’t want to damage the pleats.
  • Always check for leaks around fittings and unions. A small drip now can become a flood later.
  • Schedule a yearly check-up with us. We’ll inspect your system, replace worn parts, and make sure everything’s running efficiently.

With proper care, your filter will last longer, work better, and save you money in the long run.

Filtration FAQs

Should I upgrade from a sand filter to cartridge or D.E.?

If you want noticeably clearer water and less fine debris, cartridge or D.E. is often a smart upgrade. The best choice depends on pool size, debris load, and how much maintenance you are comfortable with.

Why does my filter pressure rise so fast?

Fast pressure rise usually means the filter is catching a lot of debris (good) but may be undersized, the media/grids are worn, flow is too high, or the system is pulling debris from algae or heavy landscaping.

How do I know if my cartridge needs replacement?

If cleanings stop restoring normal pressure, the pleats look flattened or frayed, or you are cleaning constantly with poor results, the cartridge media is usually past its useful life.

Can a leaking filter cause air bubbles in the pool?

Yes. Bad o-rings, loose unions, cracked lids, or valve issues can introduce air. Air can also come from suction-side plumbing, so we inspect the full system when diagnosing.
