Swimming Pool Filters: Diatomaceous (DE) vs Cartridge Filters

Details of Monogram's Ultra Efficient Swimming Pool Filters
A Comparison of Diatomaceous (DE) vs Cartridge Filters

All Monogram Standard and Ultimate pools get the state of the art, double cartridge, top of the line, Pentair/Sta-Rite System 3 Modular Media System. This patented filter has 10 times the filter square footage of most DE filters and consequently, requires less cleaning. Our cartridge filter has 500 square feet of filter media. A large DE filter has only 50 square feet!

The Monogram standard (which is everyone else's upgrade) usually requires only 1 simple cleaning at the end of the pool season and is performed by the person closing your pool. Cleaning a cartridge filter is also a very simple process. There is no backwashing (and wasting thousands of gallons of water), no required gloves or masks, no messy diatomaceous earth, and no extra money spent on extra chemicals. The 2 cartridges are simply removed and hosed off with a garden hose. It couldn't be easier.

This means that your filter should last the entire season without a cleaning!

1000's of gallons of water, bags of diatomaceous earth, extra chemicals, wasted $$, and most importantly, wasted hours....all are eliminated by the Monogram "Hassle Free" Filtration system.

FILTERS - COMPARISON OF DIATOMACEOUS EARTH vs. CARTRIDGE FILTERS:

  • Most pool companies include either an inefficient, inexpensive sand filter or a diatomaceous earth filter with their pools. Monogram includes state of the art, easy to clean cartridge filters.

  • Diatomaceous Earth (DE) filters are used by most pool companies and are less expensive than the best cartridge filters, but they are a major hassle and an ongoing expense.

  • DE filters require monitoring of the filter pressure gauge and when the gauge exceeds a predefined limit, the filter must be cleaned. (approx. every 6 weeks.)

  • To clean a DE filter you will need to backwash about 1000 gallons of pool water and dump the white, sandy, dirty water somewhere on your property. (It is illegal to put in the sewer.)

  • To replenish a DE filter you need to measure out just the right amount of powder from the 25lb bag and dump it into your skimmer to recoat the filter.

  • When working with DE, the sharpness of the material makes it dangerous to breathe and a dust mask is required when working with it. Also gloves should be worn to keep your hands from getting dried out and cracked. DE contains silica which is a Group 1 Carcinogen for humans! You should wear a mask while using DE.

  • You will then need to refill your pool with approx. 1000 gallons of water and add chemicals to make up for the loss of chemicals in the water you just pumped into your yard. More money and time lost...

  • If a DE filter gets a little tear (which they often do) your pool will be contaminated with all of the DE which will instantly turn the pool white and cloudy.

  • And the only advantage of a DE filter is that it is cheaper to install and filters to a smaller micron than most cartridge filters. Sand filters trap as small as 50 microns. The best cartridge filters trap as small as 10-15 microns. DE filters trap as small as 3-5 microns. Anything less than 35 microns is not visible to the human eye. So any advantage of DE is not even visible.

Bottom Line. DE filters are cheaper to install, are more of a hassle and cost much more $$ to operate, but provide no real visible benefit over the top of the line cartridge filters.
