When you buy a water filter to purify your water for drinking, cooking, or whatever else you use it for, you need to ensure that you always keep your filter clean so that it can effectively do its job. Water filters work by using a filter, not unlike your air conditioning filter, that catches the impurities as the water flows through it, allowing nothing but clean water to enter whatever receptacle you choose.

Over time, however, the water filters can become clogged with all of those impurities, keeping the filter from acting as effectively as possible. For this reason, you should always have at least one extra water filter cartridge on hand.

Here's what Wikipedia has to say about the topic:

"Increasingly used in drinking water treatment, it effectively removes major pathogens and contaminants such as Giardia lamblia cysts, Cryptosporidium oocysts, and large bacteria. For this application the filter has to be rated for 0.2 micrometres or less. For mineral and drinking water bottler the most commonly used format is pleated cartridges usually made from Polyethersulfone(PES) media. This media is asymmetric with larger pores being on the out side and smaller pores being on the inside of the filter media."

People use water filters on their water because they want to have some control over what goes into their bodies. They don't trust the water that flows from the faucet, fearing there are things in the water that are too microscopic to see, but they know they're there. And they're right. There are microbes and other impurities in the water we drink. For the most part, the impurities are harmless. If it wasn't, the government wouldn't allow us to drink it. However, you can do something about those impurities with water filters.

When you buy your water filter, it will usually come with one or two extra water filter cartridges along with it. These water filter cartridges are the extra filters that you replace the old, clogged one with.

Just as a pool skimmer removes leaves and other debris from the pool, a water filter catches all of those microscopic impurities and holds them in the filter while the clean, fresh water you desire flows through it. Those impurities have nowhere else to go, however, than to stay in that filter. If the filter gets too clogged, it is unable to do its job effectively. When that happens, you may think you're getting clean water but all you're doing is possibly putting more impurities into the water you're trying to clean.

Keep A Healthy Supply On Hand

Always keep a healthy supply of water filter cartridges on hand. They should be sold right alongside your water filter of choice at your local department store. If not, then surely there is an order form that comes along with your water filter where you can get extra water filter cartridges.

The water filter cartridges are the reason why your water filter works so well. Change it often to ensure that you are getting the fresh, clean water you desire.
