Phresh 6 Inch Carbon Filter Product Review

Phresh are a popular brand, that amongst other growing tools, manufacture high-quality carbon filters. Phresh Carbon Filters are competitively priced, last twice as long, are half the weight, and have the largest selection of filters to choose from.

Purchasing a Phresh carbon filter will ensure the atmosphere of your grow room or tent is thoroughly cleansed and free from foreign particles, dust, odors, and organic compounds. The carbon filters that are manufactured by Phresh are professional-grade systems that are used in research labs, indoor gardening, plant breeding, tissue culture, backyard & commercial gardening.

Phresh carbon filters are the only filters to use Pro -4/8 Premium Grade Carbon rather than 4/12, which performs better odor elimination and air scrubbing. The Premium Grade Carbon also increases the life cycle to an impressive 24 months!

All Phresh products are machine-packed, which is perfect for carbon filters because it positively affects their density. The top and the bottom of the Phresh filters are made from aluminum which provides a lightweight construction. Thanks to its composition, this carbon filter has been tested and proven to eliminate 99.9% of pollen, mold, bugs, and dust! Additionally, the entire body is coated in an open-air custom mesh that provides the best filtration and maximum airflow.

The inside of the Phresh Carbon Air Filter contains RC-48 Australian activated carbon which is highly absorbent thanks to its porous surface. Phresh’s partnership with Australia’s best carbon grading lab allows for independent batch testing for every filter, offering the consumer complete peace of mind!

To ensure the best filtration, all Phresh Carbon Air Filters have a high-quality pre-filter and the internal base is cone-shaped for better airflow.

The Phresh Carbon Air Filter maintains an airflow of 90% at all times by means of patent pleating. If you’re environmentally conscious, you’ll be pleased to hear that all Phresh carbon filters are comprised of 90% recycled materials.

All Phresh carbon filter models are packed and sealed tightly to provide “ultimate freshness” to ensure that they have the longest life spans possible.

This is amongst the best on the market. Not only does Phresh offer a lighter build than their competitors, but their lower weight allows them to mount onto smaller grow tents.
