Conquer odour control and air purification with our extensive selection of carbon filters and odour-absorbing products. Whether you need an intake or exhaust carbon filter, we have you covered. 

Phresh carbon filters utilize premium activated carbon to capture undesirable odours and contaminants from your indoor grow room. Our Can Filters (Lite & Original) easily mount to ductwork and feature durable construction for years of use. 

ONA Gel and odour-absorbing gels are powerful odour neutralizers that absorb smelly molecules from the air. ONA spray is a fast-acting option that breaks down odour molecules on contact. Both products are safe for use near plants. 

Activated carbon is the key ingredient in most carbon filters, utilizing microscopic pores that trap odour molecules. Our Mountain Air and Rhino brand carbon filters feature different grades of activated carbon tailored for various odour control needs. 

We carry a wide selection of carbon filters in different sizes to match your ductwork and airflow requirements. Our professional-grade odour control products provide effective solutions for neutralizing odours from indoor grow operations. Browse our carbon filters and odour absorbers today!

Q: What is the most effective method to prevent odours from permeating your living space?

A: The most effective way to achieve this is by using carbon filters. Carbon filters are widely employed in various industries, including mortuaries and restaurants, due to their ability to capture nearly 100% of odours and contaminants, making them highly suitable for home use.

Q: Where should you position the carbon filter in a grow space to capture odours most effectively?

A: To maximize odour capture, we recommend placing the carbon filter inside the grow tent, at the beginning of the ducting system you are using. This configuration is commonly used for ventilation and filtration systems, especially for those utilizing HPS or metal halide lighting with ducting. By positioning the filter at the start of the ductwork, there is minimal risk of odours escaping from the grow tent once they have travelled through the ducting to the port.

Moreover, inline duct fans set up in this manner tend to be more efficient. This setup allows the fan to simultaneously remove odours and hot air from the grow tent, reducing the chances of any undesirable smells escaping.

Q: How long is the lifespan of a Carbon Filter?

A: Carbon filters typically have a lifespan of approximately 6 to 12 months, depending on factors such as temperature, humidity, setup conditions, and more. After cleaning, carbon filters cannot be reused; they need to be replaced once they have reached the end of their effective life. Unfortunately, there is currently no alternative method for extending their lifespan. In some cases, filters may not last a full six months if the environment is excessively dusty, dry, or hot. Additionally, selecting an incorrectly sized filter for your grow room can result in a shorter filter lifespan. The filter's quality also plays a role in determining its longevity, as lower-quality filters tend to deteriorate faster.

Q: Is a Carbon Filter necessary for a small grow tent?

A: Whether you are growing in a small or large tent, it is essential to use a carbon filter to maintain clean air inside the tent. The need for a carbon filter is not determined by the size of your grow space. Even a single plant can produce strong odours that can impact the air quality in your surroundings. While odours may not significantly affect plant growth, they can have a noticeable impact on the air quality in the vicinity. For smaller grow tents, it is advisable to use appropriately sized filters rather than larger ones, as smaller filters are often available in convenient packs.

Q: Should the Carbon Filter be operated continuously?

A: It is recommended to run the inline fan continuously. However, if you want to prolong the lifespan of the carbon filter, it is not necessary to have it connected during the vegetative growth stage. You can use the carbon filter to mask odours once the plants start emitting odours during the flowering stage. During the growth phase, the filter's power can be turned off to save energy and extend its effective life.
