The Perfect Filter Solution - Covert Carbon Filters


Covert Carbon Filters are the solution to effectively remove unwanted odors and smells from your garden.

Perfect for use in grow tents, grow rooms or any enclosed grow to remove odor and improve the quality of the air. Covert Carbon Filters will purify and filter out any unwanted molds, spores, dust, pollen, odors and any other particles that can have adverse effects on your plants.

Cover Carbon Filters are designed with a 50mm thick bed of low density virgin activated coal carbon that is precisely packed for even airflow, while maximizing the surface area of carbon to more easily hold on and absorb odor particles.

Constructed with lightweight stainless steel mesh exterior that forces the air to evenly enter the packed carbon bed for a consistent long lasting performance (12-18 months).


Activated carbon filters are the best way to eliminate most VOCs (Volatile Organic Compounds), gasses, and odors from the air. Combined with a fan in a ventilation system, 99.9% of noxious odors can be trapped inside the filter for good.

Through adsorption, activated carbon literally traps the carbon-based contaminants in the air that could harm you and keep them locked tight inside the filter. Using activated carbon ensures optimal pore structure and that the pathways the air travels through the filter are optimal, so that the maximum amount of contaminant becomes trapped in the filter and does not escape into the air.


Features:

  • Machine packed activated virgin carbon allows for maximum air scrubbing
  • Highly effective, low density virgin carbon
  • 50mm carbon bed ensures all air is cleaned
  • Inner and outer mesh provides 53% open area allowing increased air flow
  • Built-in flange
  • Includes pre-filter for prolonged filter life
  • Lightweight construction allows for easy hanging
  • No maintenance required
  • Long life span (12-18 months)

All Covert Filters come with a reusable pre-filter that will filter out the large particles before they enter the carbon bed which significantly extends the life of the virgin activated carbon.

Covert Filters have a built-on flange that is easy to attach to ducting or an inline fan. The lightweight and compact design makes for easy hanging and saves space.

How to hang your Covert Carbon Filter

Once you have your Covert Filter, you still need to ensure that it gets set up properly for maximum efficiency.

We've done our best to provide all the learning resources you may require in our Learning Center on how to properly install your Covert Carbon Filter.

This article - Grow Tent Setup Guide - goes over the entire process of setting up your grow tent. At Step 4 & Step 5 in this article we highlight different ventilation setup methods and what we prefer as well as every step required to properly install your filter.


Special Ventilation Setups

Air-Cooled Lighting

Air-cooled HID light fixtures have duct flanges you can easily connect a fan and ducting to. You can see an example setup in the diagram to the right. This setup pulls air through the carbon filter, then through the light fixture and finally out of the tent.

A great upgrade for air-cooled lighting is to use a separate in-line fan just for the lighting ventilation. This will make both your light cooling and your carbon filter work more efficiently.

Grow Room Atmosphere & Ventilation

Closed Loop CO2 Ventilation

When using CO2 producing equipment inside of a tent, you want to avoid allowing that CO2 to exhaust from the tent. Therefore you want a “closed loop” system which will filter the air of odors by recirculating the air in the tent through a fan and filter. It is recommended to utilize LED or aircooled lighting to avoid heat buildup in the tent. Air conditioning is recommended for larger tents using CO2

Using CO2 for a grow tent is a more advanced technique. If you want to leanrn more about CO2 for growing we have a great article here
CO2 for Grow Tents

These images showcase different combinations of ventilation setups and how it might look in a tent of your own. There are tons of different methods to experiment with in your grow tent to get the most out of your garden every time you grow!

We want you to get the most out of your grow and knowledge is power! It is encouraged to check out this article on Indoor Grow Room & Grow Tent Ventilation Setup Tips. We've compiled all the essential information on ventilation here so that every grow room/tent, big or small, has been properly setup to achieve the best results possible.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.

Reliable, Comfortable Dumbbells I Actually Use Every Day
Style: 12 Pound, Pair, Style: 12 Pound, Pair
I’ve been using the Amazon Basics Neoprene Dumbbell Hand Weights daily, and they’ve honestly been perfect for my routine. Whether I’m doing a quick morning workout or adding resistance to a longer session, these have held up really well. The neoprene coating makes a big difference—it provides a comfortable, non-slip grip, even during longer workouts or when my hands get a little sweaty. They’re also easy to clean and don’t have that strong rubber smell some weights can have. I really appreciate the hex shape too. They stay put when I set them down (no rolling across the floor), which makes switching between exercises quick and frustration-free. The weight feels evenly distributed and well-balanced, so movements feel controlled and smooth. Overall, these are simple, no-frills dumbbells that just work. If you’re looking for reliable hand weights for everyday use—whether you’re a beginner or just need something dependable for home workouts—these are a great choice.

Style: Rack with 3 Pairs (3, 5, and 8 Pound)
I’m really happy with this dumbbell set. The weights are clearly labeled (3 lb, 5 lb, and 8 lb), which makes it super convenient to switch between exercises. The neoprene coating feels comfortable in hand and provides a good grip, even during longer workouts. The storage stand is a big plus—it keeps everything organized and saves space, which is perfect for a small home gym. The colors are also nice and make it easy to quickly grab the weight you need. Overall, this is a great set for beginners or anyone looking to add light strength training to their routine. Highly recommend!
