Pool Filters

Your pool filter is what keeps your pool clear and safe to swim in. By having a filter that is properly sized for your pool, you will have a much easier time maintaining the quality of your water. It is very important that your pool filter is maintained properly, which differs depending on which type your pool system has.

SAND FILTERS

Most pools are outfitted with a sand filter to begin with, so they are the most common filter see in residential pools
Sand filters are able to catch debris as small as 5-7 microns, which is a sufficient size to meet Canadian health standards. 
As sand filters accumulate debris, they are cleaned every 1-2 weeks by 'backwashing', which sends the caught debris in the silica sand out to waste. Every 5-7 years, the silica sand will need to be changed, as backwashing does not clear out all of the debris.

NOTE: 

It is important to be aware that the City of Ottawa bylaws prohibit the discharge of pool salt water into city sewers, so if you have a salt pool a sand filter is not allowed to be backwashed. If you have a salt pool or are thinking about converting to a salt pool, it is highly recommended that you install a cartridge filter to comply with these bylaws.

 

CARTRIDGE FILTERS

Cartridge filters are gaining popularity, as they are less maintenance than sand filters. Cartridge filters are able to catch debris as small as 1 micron, which is small enough to filter out impurities such as dead algae. Cartridge filters are cleaned by dissasembling the filter, removing the cartridges, and cleaning the cartridges with a garden hose or special cleaning solution.These types of filters typically need to be cleaned every 3 months, so twice a summer in Canada. Cartridges typically last about 3-5 years, after which they should be changed.
