The Pure Factory’s Pure Filter 350 m3/h is a lightweight activated-carbon exhaust filter designed for odor control in indoor grows. This variant corresponds to the 100/300 size, with a 100 mm mouth diameter and 300 mm body length, and a maximum rated airflow of 350 m3/h. The cartridge is packed with RC 412 Australian virgin granulated carbon for high adsorption capacity, and it ships with two interchangeable pre-filter sleeves. The aluminum body reduces weight and simplifies mounting in ducted extraction systems; install the filter at the start of the exhaust line so air is scrubbed before discharge. Typical service life is about 18 months, depending on humidity, temperature, dust load and maintenance of the pre-filters.
