Before starting your replacement spa or pool filter online shopping, you should take out time to find out as much as possible about your existing filter. You should note down the following details – model number, manufacturer, part number and dimensions of the existing filter element that you are planning to replace. All major spa and pool filter manufacturers will have websites where they provide product schematic diagrams that can be used to determine the right replacement pool filter that you require. In order to find these manufacturer websites online, you just need to enter the manufacturer name along with the words 'spa filters'. For example, Dimension One spa filters.

Having all this information will make your online shopping experience more effective and will reduce the chance of you ordering the wrong filter. The best way of shopping for a spa or pool filter is to look for the replacement filter manufacturer part number. There is a wide selection of online retailers available on the internet, who sell pool and cartridge spa filters.

We also need to evaluate the spa replacement parts that are being offered by online retailers, in order to make sure that you are getting exactly what you need. Online retailers make their filter products visible by relating each product with keywords. These keywords are generally the same information that we talked about earlier – manufacturer, part number and model number. However, you should also be aware that there are a number of after-market universal replacement filters that are manufactured by different companies across the globe. These are made to restore the original pool filter manufacturer's filter components. In order to sell these filters, they are associated with the same set of keywords that you will be searching for. Moreover, these after-market filters may or may not be of the same quality as the original filter. Therefore, just make sure that you are purchasing quality spa filter cartridges, which distinctly show the manufacturer's name.

Lastly, in order to make sure that you are ordering the right product, check the dimensions of the pool filter. Most retailers clearly show the dimensions of each product, so you can be sure that the product you are buying is the right size.
