If you have a hydroponic grow room, then the one piece of equipment you should always significant consideration to is your carbon filter. Rhino Pro carbon filters are the ultimate long-lasting carbon filter, offering arguably the highest quality carbon and engineering money can buy. There are plenty of ways to save a few quid in your grow tent, but scrimping on you carbon filter should not be one of them!
If you are pro at hydro and growing in a sealed room, then you may just need an additional carbon filter as a re-circulating air scrubber. This ensures the air inside the grow room is as clean as possible, removing all VOC’s and pathogens before they even get a chance to build up. The Rhino Pro filters will have your back covered on this for up to 24 months, ensuring that all pathogens are kept to a minimum for the duration.
HOW THE ACTIVATED CARBON INSIDE FILTERS WORKS
The activated carbon contains huge amounts of micro-pores. These tiny little cracks and crevices inside each bit of carbon create a huge surface area of all different shapes and sizes. The combination of the vast surface area and the different sized/shaped pores means that a wide array of things can get stuck in there. That’s exactly what happens to the smell as it passes through the filter. It is adsorbed (stuck) onto the surface of the carbon where it remains trapped for ever!
The particle size of the carbon itself also plays a huge role in the overall effectiveness of the filter. If the particles are too large, then the air pockets between them will be too large and air may sneak through un-filtered. If the particle size is too small, then the air will struggle to make its way through, dramatically lowering your air flow rates as a result. A happy medium needs to be achieved, so optimal air flow rates meet perfectly with the capacity to remove smells.
The carbon also has many other properties that affect its performance. Things like magnetic charge or hardness all contribute to the overall performance of your carbon filter, so always ensure you choose a highly reputable brand that will not let you down.
ABSORBED OR ADSORBED?
Carbon filters work through adsorption. Don’t let the ‘d’ confuse you! Instead of becoming one with the carbon (like a black hole absorbs a star), volatile compound (smells) stick to the side of it, or get caught up in its intricate lattices and layers. To make sure that a wide range of VOC’s (Volatile Organic Compounds – smells) can be adsorbed, you need to make sure that the carbon used has just the right sort of properties to capture that particular range of odours. The triple activated virgin Australian carbon in Rhino carbon filters is ideal for the job!
PACK IT RIGHT!
Having the right type and sized particles of carbon is simply the first step in a long journey of producing a carbon filter. These particles then need to be put in the filter housing in such a way that there are minimal air gaps throughout the unit as is possible. If there are any pockets of space, then it will not correctly remove the odours from the air, as well as causing many other issues, particularly with transport. Typically, vibrating metal plates are used to ensure the carbon is correctly packed and settled within the filter housing. The metal filter housing, is also a significant part to correctly design.
BETTER BY DESIGN
It is not simply having a decent type of carbon that determines how well a carbon filter works. The actual design of the metal housing itself has a huge impact on the overall efficiency. Having the correct length of filter and bed depth is key to ensuring that you achieve uniformly even airflow throughout the filter when it is active. Also, the size of the holes in the mesh or, more to the point, the surface area of the metal will impact on the overall airflow as well as determining how solid the whole unit is.
To ensure you have a premium working carbon filter, you need to be certain that it not only contains the most suitable carbon for the job, but also has been purposefully designed for the job at hand. With a long-standing brand such as Rhino Carbon filters, you can be certain you are in good hands.

HOW TO USE RHINO PRO CARBON FILTERS
When using a Rhino Pro Carbon filter, always make sure you have the white fabric pre-filter correctly placed around it before you connect it up to your extraction system. Larger particles that could potentially block the carbon pores will be caught by this pre-filter, so always make sure you fit it correctly. It sounds a bit like a minor point but it will increase the filters overall performance and improve its longevity.
The bed in a Rhino Pro carbon filter is filled with RC412 carbon, mined and triple activated in Australia, arguably the finest you can have in grow room filters. Simply connect the filter to the extraction fan with a length of ducting, ensuring you have formed an air tight seal. Then hang your filter up using either chain or rope ratchets, and you are away! It really couldn’t be much easier to set-up!
WHAT SIZE FAN TO USE WITH A CARBON FILTER?
It is very important to make sure you have the correct size grow room fan for your size carbon filter. If you have too small a carbon filter then your fan will not be able to blow as much air, and your grow room temperatures will quickly begin to rise. To make sure you retain control over your temperatures, while still removing all the unwanted grow room smells, then make sure you choose you fan wisely.
Every carbon filter company should provide you with a pressure curve that tells you how much pressure it will put on varying airflow rates from fans. Using this curve with the ratings provided by the fan manufacturer will allow you to calculate whether a particular fan and filter combination will be suitable.
Reading the pressure curves means looking at the details of the graphs for firstly the carbon filter, and then for the fan you are going to attach it to. The filter’s graph will have one axis with airflow in m3/h. another axis for pressure. If your fan is rated at 600 m3/h, use this figure to see what the corresponding figure on the pressure axis is.
The pressure graph of the fan will also have two axis, with the same measurements, but a different shaped curve. Use the pressure figure gained from the filter’s graph to see what the corresponding drop in air flow is for the fan.
When you are looking to buy a fan or filter, you can use the above steps to make sure you get the right ones for the job!

WHERE TO PLACE YOUR RHINO CARBON FILTER
You want to place your Rhino carbon filter in a position that gives you nice and even air flow throughout your entire grow room. Typically, it is placed at the highest point in a hydroponic grow room to remove as much of the hotter air as possible. You then need to consider it overall position compared to the intake system you have. EG, if you have an intake fan at on side of a grow room, consider putting the filter at the opposite end of the room.
Ideally the filter will be in the middle of the room, with an intake system the releases air around the entire outside of the room. This will give you the most uniform conditions throughout your hydroponic grow room, but takes a bit more effort to install. The easiest way is to create a ring of ducting off of your intake fan with a T piece. Have the ring of ducting go around the perimeter of your room and pierce holes at regular intervals to achieve a uniform airflow. This also avoids the problem of having a cold intake fan blowing directly on to a plant, negatively effecting its growth.
Larger sized or odd shaped rooms will always need a little bit more thought going into the correct placement of the carbon filters. Please feel free to pop down to our grow shop and we can discuss bespoke filtration options to tailor it to your exact needs.
FILTERS AND HUMIDITY
Water and carbon filters do not mix! If the carbon inside your filter gets too wet, then it will drastically effect its performance. Having too high a humidity may be good for your plants(in the early stages of life particularly) but not so good for a carbon filter. If the relative humidity(RH) creeps much above 80% in your hydroponic grow room, then the filter’s performance will begin to become compromised.
Essentially, a high RH fills up the pores within the carbon with water. As the micro pores in the filter are now filled with water, they cannot be filled with plant smells like you wanted them too! Always ensure you are adequately monitoring your humidity levels to ensure this situation does not occur. If you find you have got into this position and your filter is full of wet carbon, then simply place it in a cool and dry environment to dry back out again. Once the carbon has completely dried out the it will be back to normal working order.
One obvious thing to consider when building your room is that any humidifying equipment, will not be situated directly under your carbon filter. Not only will the constantly high RH damage performance, but also any deposits left from any unclean water in the supply will not be able to taint the units performance. This is particularly prominent using humidifiers in hard water areas.
TIPS ON USING RHINO PRO CARBON FILTERS
Make sure the ducting is secured to the fan and filter with as great an air tight seal as possible, otherwise un-filtered air may by-pass your filter and find its way to the outside world. Air leaks can be identified by lighting a splint and running it along your extract line. If there are any gaps then you will see the smoke get sucked into the duct run, indicating you need to give more attention in this area to achieve an air tight seal.
Try to avoid any bends, kinks or slackness in the duct run. These will all lower the amount of air being extracted through the system. Ideally have it as straight and as tight as possible to ensure minimal amounts of back-pressure placed on the fan, giving you the highest air movement possible.
Avoid placing your filter directly above humidifiers, or anywhere that has a consistently high relative humidity. Deposits left from unclean or hard water will stain your equipment (like reflectors) and also clog up your carbon filter. Ideally ensure the water supply is from de-ionised or RO water.
Replace your ducting sleeves every 3-6 months for maximum effectiveness. A dirty pre-filter can drastically reduce the rate of air flow through your extraction system.
