ONA Pro Block

ONA (Odour Neutralising Agent) is a well-known brand specializing in professional-grade air purification and odor removal. Originally formulated for use in commercial and industrial settings where strong smells were problematic, the brand has expanded into the consumer market with various formats including blocks, gels, and sprays.

Created and manufactured in Canada by Odorchem Manufacturing Corp., the product relies on a complex formula of essential oils to neutralize odors rather than simply masking them. The ONA Pro line represents a high-performance version of their standard formula, designed for heavy-duty environments while remaining environmentally friendly and non-toxic to humans and animals.

Ownership remains with the original Canadian founding company, Odorchem Manufacturing Corp., which continues to operate out of British Columbia. The brand is distributed globally through various hydroponics and industrial supply chains.
