Replacement Cartridge
A Complete Guide To Cartridge Replacements

Forgetting to replace your water filter cartridge defeats the whole point of having a water filter! It’s the cartridge inside the water filter housing that counts.

Cases of water contamination are becoming more and more frequent. It is therefore better to stay on the safe side with, firstly, a good water filter in your home and, secondly, insisting on your water filter supplier providing you with a great after-sales service; reminders to replace the cartridges.

Consider your filter cartridge as a sponge that collects contaminants from the water that filters through it. Filters can accumulate bacteria, pesticides, lead, fluoride, and other pollutants if they are not replaced on schedule. The system becomes less efficient as the filters clog.

The water could even pass through unfiltered if the filter media has expired, meaning that you will be consuming those very contaminants you wanted to be rid of.

It can be very confusing to keep tabs on which filters need to be replaced and when. That is why a convenient reminder from your water filter supplier is a headache-saver. Here are some pointers

When Should Water Filters Be Replaced?

  • When your water becomes unpleasant to taste, or if it emits an odour, it’s most likely time to replace your filter.
  • A gradual decrease in water pressure could also indicate that you need to replace the filter. You can also visually inspect your filters to determine if they are dirty and need to be changed if they have clear containers. 
The longevity of filters is based on how much water you are putting through them versus their capacity.
For example, a water filter with a capacity of 10,000 L will last 10 months if you are filtering 1000 L per month.

H2O | BWT offers a range of filters which include: countertop filters and undercounter filters. When you determine which specific filters need to be replaced, visit the product description on our website. If you’re not sure when your water filter cartridge needs to be replaced, simply contact the person that you bought the filter from here in order to check.

Which Replacement Cartridge Is Best for My Filter?

Filter cartridges do not come in one size fits all. Even if generic cartridges seem to fit inside the housing of a water filtration system, even the smallest difference in size could cause unfiltered water to pass through the cartridge rather than through it.

While non-branded generic water replacement cartridges are often cheaper,  they may not provide the same performance quality as the original replacement cartridge. Buy only from experts like H2O/BWT to be sure you are getting the water filtration efficacy and value that you should be getting.

Of course, the easiest way to know which water filter cartridge needs replacing, is simply to look at the label, pick up the phone, and call your nearest H2O | BWT branch for a replacement.

What Are The Benefits Of Water Filters?

Your drinking water might contain some contaminants, no matter how clean and refreshing it looks. Most contaminants are not visible to the naked eye. The only way to determine if your water is contaminated is to have it tested and to find out what the specific pollutants are.

Depending on the type of contaminants present in your water, installing a reliable, high-quality water filter can help you avoid the following:

There are many impurities in tap water that can be removed by filters, including chlorine, zinc, lead, copper, cadmium, mercury, lead, bacteria, fluoride, and many more.
By removing hardness-causing minerals from your water, water filters improve the taste and smell and reduce the damage the minerals cause to your hair and skin, pipes, plumbing, fixtures, and appliances.
There are a variety of advanced water filters on the market such as activated carbon filters and reverse osmosis filters that are highly effective at trapping those stubborn pollutants that wreak havoc on your health and your home.
In addition to removing chlorine, chemicals, pesticides, heavy metals, and bacteria, water filters also provide better-tasting and better-smelling drinking water.
By removing chlorine and chlorine byproducts from drinking water, they can reduce the risk of gastrointestinal disease and cancer, including colon, bladder, and rectal cancer.
Clean, healthy water is a common benefit of water filters.
