How To Choose Water Filters


Higher Quality – More Cost Effective

Doing proper research is very important if you want to know how to choose water filters. With questions about water supply safety and people’s conscious desire to lead a more health lifestyle – home filtering systems have become very popular over the years.

It is not an unreasonable stretch to say that many consumers have bought expensive, ineffective filtration systems.

The time is now, to give you, the average consumer, valid information that will correctly show you how to choose water filters.

Things To Consider

1. First off, pure water is something that exists only in a lab. You may have seen a lot of ads on tv or in the print media saying that their filtration system will give you pure water. It won’t.

Filtering units reduce water contaminants, in some cases they might virtually eliminate particular contaminants. But you won’t get 100% contaminant-free water with any filtering device.

Distillation may remove a wide amount of contaminants but this process of contaminant removal has a downside. It isn’t very effective at removing organic chemicals (unless used in conjunction with carbon filters).

Distillers produce water at a very slow rate and at a high per-gallon cost.

2. Consider filter life expectancy and capacity. Small units such as pitcher filters are very poor in this regard.

pitcher water filter might be inexpensive but its small cartridge size means their filtering capacity is also limited.

These devices tend to remove limited amount of contaminants – maybe chlorine, lead, and particulate matter at best. Depending on the micron rating, they might be able to remove cysts as well.

But here is the kicker – although a pitcher filter may be inexpensive (around $25), the rate at which they produce filtered water is at a higher per gallon cost than more sophisticated filtering devices.

Such a device may be able to produce 30-100 gallons of water before the cartridge needs to be changed. Replacement cartridges may cost about $15 – so it produces filtered water for a minimum of 15 cents/gallon.

Let us say your family use 5 gallons of water a day, you’ll have to change the filter cartridge every 20 days which amounts to around $274 annually. Add that to the cost of purchase and you get $399.

On the other hand, for around $100, you could have bought a larger drinking water filtering system that not only filters a wider range of contaminants but can last for 500 gallons.

Let us say replacement cartridges cost around $50, it can filter water for around 10 cents/gallon.

If your your family consumes 5 gallons of water a day, your annual cartridge replacement would be $182.50. Add that to the purchase price of $100 and you get $282.50.

So in the end it would be a better idea to buy the more expensive drinking water filter.

3. There is a great way to an unbiased evaluation of any water filtration system you intend on buying. I am talking about having experts who know the ins and outs of filtration advising you.

These experts will tell you whether or not the filtering device you intend on buying can actually remove drinking water contaminants as claimed. This checks whether or not a water filtration unit meets strict standards for performance.

To find out more this “unbiased evaluation”, see water filter ratings.

Armed with that information, the question of how to choose water filters is one that you will be able to answer with ease.
