Is A Carbon Filter Necessary?
To answer the above question quickly, No. An activated carbon filter system (also called a carbon Intake filter, carbon scrubber) isn’t, technically, necessary. Perfectly fine
What Exactly Are Activated Carbon Filters and Carbon Filtration?
An activated carbon filter captures, like a sponge, various containments and stops them from going outside the tent; also it prevents bad air from getting inside your grow room. A carbon filter’s job is to filter a carbon particle from getting into your grow area by capturing various smells and other potentially volatile in-bound chemicals. It does this by, after capturing the various pollutants, filtering them through activated substances like charcoal or even coconut shells.
What are Activated Carbon Air Filters?
Carbon air filters are the filters most commonly used to remove gases. They are designed to filter gases through a bed of activated carbon (also called activated charcoal) and are usually used to combat volatile organic compounds (VOCs) released from common household products. They are also often used to remove odors from the air, such as the smell of tobacco smoke. They cannot remove fine particles like mold, dust, or pollen from the air.
The two most common substances that are commonly used for carbon filtration are activated charcoal and activated coconut shell carbon.
In summary, carbon filtration, with the help of carbon filters does the following:
- Air Purification-A C02 filter is able to filter out contaminants from getting inside your
grow tentand potentially damaging your crops.
- Smell Control– A quality carbon filter helps reduce or even eliminate the distinctive weed smell that comes from a growing
The vast majority of all carbon filters use activated charcoal, which is primarily burnt coal or wood, for carbon filtration. Activated carbon is specially treated to have more tiny holes or pores. In turn, more holes equal better filtration.
If you are curious, look at the appendix for more info on how activated charcoal is manufactured.
Activated Coconut Shell Carbon Filter
Activated Coconut shell carbon filters are made from coconut husks that are specially treated to enhance filtration. One advantage of coconut shell filters is that they are natural, which means that these filters will not react with any outside pollutants. Additionally, carbon filters also have more micro-pores that result in a coconut filter being able to block out smaller air contaminants.
How Can You Gauge The Efficiency Of A Carbon Filtering System?
CFM or cubic feet per minute is the standard that you should look for when it comes to air filters. CFM indicates how many cubic feet per minute a carbon scrubber can filter.
The CFM size that you need depends upon the size of your grow room. So, more CFM is not necessarily better. Check this article out for a guideline on what CFM size you should purchase.
The Phresh Carbon Filter is one of the top-rated, filters on the market. The Phresh Filter is expensive but affordable. However, it is not a HEPA filter.
Proper Grow Area Ventilation System
And Exhaust System Also Needed
Along with a quality air carbon filter, you will also need a suitable ventilation system for your
On a side note, grow room ventilation has numerous other purposes than maximizing air circulation. They also help with odor control and work to prevent mildew from creeping up on your plants.
A suitable ventilation system consists of both a circulating and inline fan. Both those combined allow the air to circulate, which in turn means that the filter can do its work.
Grow tent or grow room ventilation will have the following:
- Circulating Fan or Oscillating Fan-The circulating fan’s job is to mimic the breezes that your plants would get if the plants were growing outside. How many and the power that you will need depends upon how big and how many grow tents that you have.
- Exhaust Fan or Inline Fan-The inline fan is used to take in new air and expel out the old air through via ducting. An inline fan combined with a carbon filter can make the air from a growing area odorless.
As I stated carbon air filters aren’t necessarily needed. However, it should be mandatory for all indoor growers, who live in the city or who have visitors over often. So, do your research, and get the best one for your particular situation.
Does an Activated Charcoal Filter Block Smells?
Does Activated Charcoal Filteration Work?
Charcoal has been used for centuries as a filter. In fact, gas masks in World War I even used carbon filters. So, if activated carbon filters can protect soldiers from mustard gas or another chemical, it sure can work as an effective odor neutralizer.
In general, activated charcoal, which is made from burnt wood or coal, is designed to have more holes than non-activated or regular charcoal. The more wholes result in better smell absorption and also better and increased ability to filter out more pollutants than standard carbon.
Activated carbon or a charcoal filter is made from burnt wood, coal, or coconut husks that are burnt at temperatures exceeding 400 degrees. Afterward, it is cooked again at over 800 degrees. (They are also treated with a substance that makes the carbon have even more holes than non-treated charcoal)
Activated Charcoal (Wood) Filteration Manufacturing Process
Coconut Carbon Fileration Manufacturing Process
Ozone generators are marketed as air, quality, control device. Some of the manufacturers claim that they will help with both air quality and also help control smells. The question though, is do they work, and if so, to what extent should you use them in your grow room or
How Do They Work?
It makes ozone by separating oxygen molecules into a single atom. This single atom then will morph into other oxygen molecules that in turn produce Ozone. Currently, the conversion is done by either electricity or ultraviolet radiation.
Is Ozone Dangerous?
Yes, too much of it can damage your lungs and cause chest pain, breathing issues, and it will give you a soar throat. Additionally, it can be especially harmful to people that have asthma, COPD, or other respiratory afflictions.
Do They Help With Air Quality?
Per the EPA, no. The EPA states that ozone levels that do not exceed the listed safe levels will not scrub out of eliminating any indoor air pollutants. Obviously, ozone generators are only designed to produce safe levels of gas. So, based upon the EPA, the only way it would be effective would be if it generated unsafe levels of ozone.
Do They Work For Odor Control?
The EPA does not mention anything concerning ozone generator and odor control. I did find an article, which stated that the changing of the composition of the oxygen molecule might result in eliminating odors. However, based upon the EPA Ozon generators are a waste of money and you’d be better off using the money spent on a better carbon filter or another type of
