Importance Of Using Carbon Filters For Grow Rooms

Prior to making a purchase for a carbon filter, it would be best to understand its benefits and importance.

One important point of using a carbon filter for your grow room or hydroponic system is that it makes use of carbon which is a highly reliable absorbing agent with regard to odor and smells. It can effectively filter and absorb the most pungent of odors as well as the unnoticeable scents.

In addition to eliminating smells, it also disintegrates pathogens found in the air which can cause damage to plants and harm to humans – especially those whom are sensitive to allergens.

In addition to eliminating smell, it also decontaminates the air from toxic odors coming from used fertilizers, pesticides, chemicals and soil contaminants. While it provides comfort by making strong smell emitted by plants go away, it also provides safety from being exposed to chemicals and pathogens.

Choosing The Ideal Carbon Filter For Your Hydroponic System

With the wide array of carbon filter choices available in the market, it’s not easy to find the perfect option for your needs. To relieve you of the daunting task of going through each product, we’ll provide you with a comprehensive guide on how to find your ideal carbon filter.

Follow these few considerations and you’ll be sure to have the best hydroponic carbon filter suited for your needs.

1. Size

One thing you need to consider when buying a carbon filter for your grow tent or grow room is the size of the filter. Air conditioning system, exhaust system as well as lighting system requires a specific size of carbon filter prior to installation or set up.

It is important that you consider the size of the carbon filter and make sure it matches all your other components. While the size is prerequisite to the compatibility of the components, it is also an important consideration seeing that some spaces may be compact or tight which larger sizes of carbon filters may not fit.

2. Thickness

When it comes to thickness for your carbon filter, there is only one thing to bear in mind – the thicker filter means more carbon. This means that if you have a thick layer of carbon, you will have a more efficient air filtration out of your carbon filter. However, there’s one thing to note when the thickness increases is that its price can also go up.

3. Compact

As much as possible, go for a carbon filter that is compact and doesn’t have air pockets in between. Having a compact carbon filter means odor and smell are deeply filtered through the very small spaces around the carbon granules.

Also, having a compact carbon filter provides reduced noise as well as vibrations.

4. Durability

Just like when buying any other machine component, you would want to make sure that it is made from durable materials to ensure long life of use. With regards to carbon filters, you may want to make sure that its top, base and flange is made from durable materials.

One common preference of material for these parts is aluminum. This is for the reason that while it is much lighter than other metals, it is durable and is resistant to rusting and corrosion.
