All You Need to Know about Carbon Filters

Carbon filters are purposely created to control the odor inside a grow room or a grow tent. Be that as it may, it does not stop there, they also are designed to eliminate pathogens by breaking them down into harmless states.

This often happens inside a grow room and there is an accumulation of harmful or toxic chemicals in the air that carbon filters ultimately takes care of. Plant growers or farmers will sometimes eventually use spray pesticides, fertilizers, and nutrients to their plants.

Nonetheless, these substances have their specific odors and most of them are deemed unpleasant. With that said, the accumulated smell can expectedly create a very pungent scent that can be removed using a carbon filter.

In addition to that, these combinations of different chemicals and substances not only develop a very unpleasant smell, they can also produce harmful fumes that are not helpful to your growing plants. This is when the carbon filter is also used for. 

What to Look for When Choosing the Best Carbon Filter for Grow Room

When picking out the best carbon filter for grow room, you have to look into some critical factors. This will assist you in having an idea of which product is best for you.

1. Durable

Like many other tools that you intend to purchase, durability is a big factor to consider. Durable tools can last longer which can save you the hassle and cost of having them fixed or even replaced in the future.

When looking for the ideal carbon filter, make sure that its top, base, and flange are made from durable materials. The best options for this are aluminum. The reason being so, is that aluminum is known to be corrosion and rust resistant making tools made using it highly durable.

2. Compact

Another crucial factor you need to look into is how compact the carbon filter is. Being compact simply refers to how tightly packed the carbon granules are. The primary purpose of carbon filters is to deeply and thoroughly filters the air.

In order to effectively do that, the carbon granules should be packed tightly enough for air to flow through easily but at the same time be filtered as well. Having a compact carbon filter also makes it less noisy since there will be less vibration while it operates.

3. Size

Of course, size is another important factor. You need to make sure to get the right size of the carbon filter that will fit or match to the prerequisite components.

Prior to setting it up, make sure to take note of the specific size of the carbon filter that the exhaust system, air conditioning system or even the lighting system needs.

4. Thickness

Finally, you also need to look into the thickness of the carbon filter. The thicker the carbon filter means it contains more carbon. Having more carbon means the passing air would have to go through more layers for it to be filtered more efficiently.

And this is vital to all carbon filters. Be that as it may, this also means that the thicker the carbon bed is, the more costly it can be.

These products are undeniably the top choices among the rest of the carbon filter for grow room offered in the market now. Together with the tips, I have shared on what to consider when picking out which is the best, you can now opt for one that will be perfect for your use.
