Introduction

A clean pool filter is crucial for maintaining bather comfort and extending the life of pool equipment. This eHow will show you how to clean a crushed sand filter, a diatomaceous earth filter and an enhanced cartridge filter.

Instructions

Step One

Clean a crushed sand filter by back flushing water through the system on a regular basis (about once a month). Your system’s pump station will come with instructions on how to reverse the water flow to clean the debris from the filter.

On a spring evening in 1956, company president and founder Dick Meissner sat down in his garage to begin work on his first sewing contract. Phil Anthony of Anthony Pools had just given him his first order to produce the Anthony McIntosh filter bag. Working alone and at night, Dick laid the foundation for the company that has grown to become the largest manufacturer of swimming pool and spa filter elements in the world.

In those early years, residential DE filtration was in its infancy. As the market started to grow, Dick received additional sewing contracts, first from Swimquip, then from Landon, Pac-Fab, and Paddock of California. By 1959 this part-time venture had grown into a full-time business. The fledgling company hired two employees and quietly moved into a 2,000-square foot building in Van Nuys, Calif. Within one year the young company doubled in size and by 1962 it occupied 6,000 square feet and had five full-time employees.

With the advent of the cartridge filter, the company saw its next opportunity. Early cartridge elements were made of a paper-type material that did not hold up well in the swimming pool environment. Realizing the future potential of cartridge filtration, Meissner set out to develop a manufacturing process to enhance this new medium. In 1964, the research and development yielded the industry’s first cartridge element made with a new spunbonded, 100% polyester material called Reemay¬. Developed by Dupont and adapted to cartridge filtration by Meissner, Reemay has become the primary filter material used throughout the pool and spa industry.

The period from 1964 to 1972 saw steady growth of the new Reemay cartridge systems. At that time, however, individual cartridge size was limited to only 6 square feet. The filter system achieved its total surface area by manifolding numerous small cartridges. These early cartridge filters worked extremely well but were difficult to clean and maintain due to the number of small elements involved. Then in 1972, Meissner, working with Purex, developed the industry’s first extended surface, single element cartridge. Meissner’s new manufacturing technology yielded a 100-square foot filter sytem using only three individual cartridges. This concept quickly caught on and single element 25-, 50-, and 75-square foot filter systems utilizing Meissner’s cartridges soon were introduced by American, Baker Hydro, Hayward, Premier, Sta-Rite and others.

Throughout the early 80’s Meissner continued to work as a supplier to the brand name pump and filter producers to develop and improve cartridge filtration. By 1984 Meissner elements, both DE and cartridges, were being utilized in virtually every major brand name filter system. To meet this growing demand, the company developed state-of-the-art high speed production equipment. Unique to Meissner, this manufacturing capability allowed the company to carve a niche for quality and delivery that is unsurpassed today.

1985 became a pivotal year for Meissner when several brand name companies began producing their own Reemay elements. Faced with a loss of business, but having tremendous production capacity, the company re-invented itself. Retaining its core OEM business under the Meissner label, the company introduced and promoted the Unicel brand of replacement filter elements. For the first time, the entire range of replacement elements built to O.E.M. specifications was made available to wholesale distribution from a single source. Dealers and service technicians could easily obtain replacement cartridges from their local distributor, even if they did not carry that particular brand of equipment.

By staying focused and specializing in filtration, Unicel has developed expertise in a very critical area of the pool and spa industry. Today, Unicel services both the spa OEM market and wholesale distribution trade. Whether it is media development or cartridge design, Unicel is recognized as the industry leader.

Swimming pool filter cartridges are the silent partners that help keep your pool’s water sparkling clear, clean and fresh. Pool filter cartridges work 24 hours a day filtering out even the smallest debris and sediment from your pool’s water.

There are three types of swimming pool filters, sand, cartridge and DE (diatomaceous earth). In this article we are focusing on cartridge filters but for the sake of clarification I will give a brief overview of all three types.

Sand Filters
Sand filters remove impurities by using sand to collect and attract the debris. Sand filters have to be backwashed (running the filter in reverse) to remove the water waste. This is a very manual process that must be done every few weeks.

DE
Diatomaceous earth is a mined substance used to coat “grids” in the filter. These coated grids capture the impurities. As more impurities are captured the pressure begins to rise. When the pressure has risen to the maximum level, you manually backwash the filter just like sand filters and then “recharge” it with more DE powder.

Cartridge
Swimming pool filter cartridges work by allowing water to pass through a very fine filter surface. This filter surface captures any impurities that attempt to pass through and hold them until you clean the filter cartridge or replace it.

Cartridge filters have more surface area than sand filters. This allows for fewer clogs and much easier maintenance. Cartridge filters also operate at a much lower pressure than sand. This causes less backpressure on the pump so you have a greater flow of water through the system.

The swimming pool filter cartridges can filter out anything down to 5 to 10 microns in size. To put this in perspective, a single grain of table salt is about 90 microns in size. Anything below 35 microns is invisible to the naked eye.

Swimming pool filter cartridges are extremely popular because they are very easy to maintain and relatively inexpensive. Basic cartridge maintenance can be performed by simply rinsing off your cartridge with a garden hose or soaking them in detergent. However, the best way to ensure a clean and sparkling pool is to just simply replace them.

Replacing your cartridges is very easy and you don’t even need the help of a professional. You simply remove and discard the old filter and replace it.

Be sure to get your new filter before you dispose of the old one. To replace your swimming pool filter cartridge you should write down the brand, the size and the part number (if it has one). Always double check the cartridge dimensions against the one that you are try to replace. Cartridges are the preferred method of many pool owners because they are simple to replace and they are a very cost effective way to keep your pool crystal clear.

Jacuzzi has become synonymous with baths and spas but the seven Jacuzzi brothers who originally emigrated from Italy made their first claim to fame by inventing the first enclosed cabin monoplane. This became the airplane that carried mail for the U.S. Postal Service and carried passengers from the San Francisco Bay Area to Yosemite National Park.

It wasn’t until 1956 that they had the idea of treating a family member’s arthritis symptoms with a hydrotherapy pump. The Jacuzzi brothers invented a pump and a small niche business was born.

The original J-300 portable pump was sold primarily to hospitals and schools until Roy Jacuzzi (a third generation family member) was able to capitalize on American’s interest in health, fitness and leisure activities. It was in 1968 when Roy invented and marketed the first self-contained, fully integrated whirlpool bath that incorporated jets in the sides of the tub. It was this early invention that created a new industry.

Roy incorporated larger units that could accommodate several people along with heating and filtration systems to keep the water warm and clean. This led to the creation of the first spa in 1970.

The Jacuzzi family sold the business in 1979 to New York-based Kidde Inc. Roy was the only family member who didn’t leave the business or retire. Roy continued to run the operations into a decade of new designs including the Avanza.

The Avanza was a whirlpool bath / hot tub that could be used in either configuration. It could be installed inside or outside a house and was the first all-in-one hot tub/whirlpool bath.

After a career marked with innovation and improvement, Roy Jacuzzi was inducted into the National Kitchen & bath Hall of Fame as a result of his many contributions in the innovation of hydrotherapy for home use.
Since then Jacuzzi has become the world’s most recognized and largest selling brand of jetted/whirlpool baths and spas. Besides getting the first whirlpool bath patent, Jacuzzi has 250 worldwide patents for advancements in pump systems, jet technology, air controls and product design.

Jacuzzi has always believed that baths and spas are about more than just getting clean. That is why they continue to create high-performance products that celebrate water’s ability to refresh and rejuvenate in inspiring ways.

It’s this dedication to excellence that continues to make Jacuzzi the leading choice for jetted/whirpool baths and spas.

The best way to make sure that your pool stays clean, clear and beautiful is to make sure that your filter system is functioning properly and is properly maintained.

The best way to quickly determine if your filter is operating properly is the quality of your water. If your water looks cloudy, grey or has debris in it, it’s probably time for filter maintenance.

Another effective way to determine the quality of your filter is the filter pressure indicator. This is usually a gauge or meter that is on the outside of your filter housing.

As your cartridge begins to accumulate dirt and debris it becomes more difficult for the pump to circulate water through the filter. As a result, the pressure on your filter system increases and less water is circulated through your system. Not only does this increase the workload on your pump, it also reduces the quantity of water that is filtered. This leaves more dirt and debris in your pool.

When the pressure of your filter rises 8 to 10 psi above the level it was at when your filter cartridge was new it is time to either replace you cartridge or clean it.

The first concern in replacing or cleaning your filter should be safety. This is especially true if your filter is fitted with a pressure-clamp. Pressure-clamps can sometimes “blow” under certain circumstances. This can cause property damage, severe injuries and sometimes even death.

You should ALWAYS refer to the manufacturer’s guidelines before performing maintenance on your swimming pool filter.

The first step is to turn of the electricity to the pool and pump. After you have verified that all of the power has been cut you should open the pressure release valve until the hissing sound stops. You are then ready to move to the next step.

After you have turned off the electricity to the pump and swimming pool, and released the pressure valve you should remove the retaining band and lift the lid.

There are three types of swimming pool filters: sand, DE (diatomaceous earth), and cartridge. Pool filters usually fall into one of two categories, pressure or vacuum pool filters. We will cover the third type, cartridge filters.

Swimming pool filter cartridge filters work by allowing water to pass through a very fine filter surface. This filter surface captures any impurities that attempt to pass through and hold them until you clean the filter cartridge or replace it.

Cartridge filters have more surface area than other options. This allows for fewer clogs and much easier maintenance. Cartridge filters also operate at a much lower pressure than sand. This causes less backpressure on the pump so you have a greater flow of water through the system.

The swimming pool filter cartridges can filter out anything down to 5 to 10 microns in size. To put this in perspective, a single grain of table salt is about 90 microns in size. Anything below 35 microns is invisible to the naked eye.

After you remove the lid the cartridge will be exposed. Remove the old cartridge and make careful note of how it was seated in the housing. Replace it with the new cartridge. After the new cartridge is installed, replace the lid and retaining band and close the pressure release valve.

You can then turn the power back on and check your filter. Also make note of the system pressure as this will be your baseline reading for future maintenance.
The whole process usually takes under 10 minutes and leaves you with a pool that is clean, clear and healthy.
