Recently, I was having a conversation with an acquaintance about how spending time in the grow room has become an escape from all the noise in the world.
However, he was concerned since the wife had told him to smell the plants down or get rid of the plants. Fortunately, I have a solution since I had a carbon filter in my grow room back at home. I recommended that he get the 4 inches one as the grow tent was not that big.
You can imagine what followed was a list of questions on the specifics of the best 4-inch carbon filters. At this moment, I figured several other people could be in the same situation and may need a little guidance on purchasing the best 4-inch carbon filter.
What Exactly Should I Look for in A 4 Inch Carbon Filter?
The assumption is that all of us know that a 4-inch carbon filter will be effective for spaces that are 4*4. I recommend that you do not overwork it by putting it in a larger space, as this may affect its lifespan.
With this understanding, the first thing that you should look out for in a 4-inch carbon filter is the carbon’s quality inside the filters. The best way to get to understand the quality is to look for where it is sourced.
If the manufacturer has not indicated, you can always question them. This is an important question because different areas have different carbon with different absorbent rates.
You don’t want to find yourself with carbon that is so poor in absorbing that you will view your carbon filter as a waste of money. I recommend that you purchase the product that has carbon sourced from Australia.
The durability of the 4-inch filter is another element that will aid in the selection of the best. Here, I acknowledge that people will have different needs.
There are those looking for a temporary carbon filter with a low budget, while others are looking for something that will last them a long while. Depending on your needs, ensure that you understand how long your filter would last.
However, suppose you do not use it as recommended (changing the pre-filter or washing it regularly). In that case, you can be sure that it won’t last you as long as the manufacturer has indicated its lifespan should be.
I also recommend looking out for replaceable pre-filters. Some carbon filters will not come with a replaceable pre-filter which means that once it stops operating (which maybe after a few months), you are back into the shopping field for a carbon filter.
This is not only disappointing but also economically draining. A 4-inch carbon filter that has a replaceable or, better still, a washable pre-filter such as the Amagabeli 4-inch Carbon Filter will work to your advantage, especially economically.
Versatility is another element that you should look out for. This means looking out for the carbon filter used as both an inline or an exhaust fan. This ensures that you can place the filter in numerous spaces and extend its lifespan.
How Do I Take Care of My Carbon Filter?
Taking care of your carbon filter will increase its life span. I believe that you should not purchase equipment to mismanage and poorly maintain it as this will be a waste of limited financial resources.
Maintaining the carbon filter is easy. When the filter is new, it may have some excess carbon. Thus, it is always advisable to vacuum first before the first use to remove this excess carbon.
Another way is to ensure that you always have an extra fabric sleeve that increases the length of the filter. Using an inline fan with the filter is another recommendation. This allows you to use it in different positions prolonging the life of the carbon filter.
Cleaning the carbon filter is also another essential part of maintaining it. However, most people may be wondering how they can clean this carbon filter.
Will I need to disassemble the entire filter? Will I use water?
These are some of the common questions that may be going through your mind. However, cleaning is quite simple as you begin removing it where you fixed it in your space.
It would be best if you then took it to an open space to facilitate ease of cleaning. First, shake it vigorously to ensure that any trapped dirt or dust is removed. You will then proceed to spray water and submerge the filter in soapy water (mild).
This soaking should be for about 15 minutes, whereafter you rinse. Retain the filter in the open space allowing for complete drying before taking it back to your space.
Carbon is undoubtingly one of the most important components of the carbon filter. However, the dampness of this carbon may be detrimental to its longevity.
This is if the filter is in a place that has high humidity. As part of the maintenance of this carbon filter, it is important to have the activated carbon dry under the heat of the sun so that it can last longer and ensure the effectiveness of operations of the carbon filter all through its lifespan.
Finally, get the right room’s right size to avoid overworking the filter and avoid sparing it after it has reached its maximum capacity, as performance may not be as good. Better still, you can get a larger size than the size of the room, extending its lifespan.
How Will I Set Up My Carbon Filter?
In the product review, we talked about how exciting it is to get a 4-inch carbon filter that is easy to install. It saves you a lot of stress, including engaging in a home improvement or maintenance professional’s services.
However, I do not want to assume that all of the readers here have interacted with carbon filters and understand how they should be set up. As such, I will cover how they should be set up in the next paragraph, after which you will agree with me that it is quite an easy undertaking.
If you are placing it on the ceiling within your space, you can hang the carbon filter from the ceiling. You will need to use hooks and straps, which almost every manufacturer will pack with the air filter. The next thing here is to take the air ducting, which you will run through a wall, hooking up an inline fan on its outside.
If you plan to have the filter outside your space (for instance, outside your grow room), you should have something to hold it up. You can place a wooden rack or even a milk crate. The equipment doesn’t need to be held up as you could also hang it.
Find what works best for your space. After this, you can then run the air ducts, and the filter will start operating.
