Eventually, you'll need a replacement coconut, KDF, or Catalytic Carbon filter. At a certain point, they your water filter won't be able to perform like it once did. You'll start to see more contamination coming through your filter, which sort of defeats the purpose of using one! But, it can be confusing trying to figure out which one of these is right for your specific filter. And how long do RO membranes last? We'll answer all this and more.

What is catalytic carbon filter?

While it sounds complicated, a catalytic carbon filter is just a type of filter used to remove chloramines and hydrogen sulfide from your water source. These chloramines can wreak havoc on your grow, so you need to get them out. And, catalytic carbon has incredibly adsorptive characteristics, with the ability to promote chemical reactions to clean your water. These are a more advanced form of filtration. .

What is a Coconut Carbon filter?

As it turns out, coconut shell is a renewable source of high-grade carbon. This type of filter works wonders on contaminated water, as it is nearly 50% more effective than other types of membranes or filters. It can also remove a wide range of different contaminants and particulates.

What is a KDF filter?

KDF, also known as Kinetic Degradation Fluxion, is a super high purity copper-zinc formulation. It uses a basic chemical process known as redox, which is able to remove a ton of different contaminants including:

• chlorine
• copper
• lead
• mercury
• hydrogen sulfide
• iron
• and more

When do I need to replace my filter?

Replacing your filter is something you need to do every 2-3 years, but this is just a guideline. It really comes down to how contaminated your original water source is, along with how much you use it.

Your filter won't degrade at the same rate as everyone elses, because you have a specific feed source and you use your filter a certain amount per day.
