ONA Liquid Odor Neutralizer 4L Jar - Fresh Linen

Water-Based Liquid Odor Neutralizer for Misting Systems, 4L Jar

Spraying a fragrance over an odor is a stopgap that fades within minutes, and it does nothing for odor already sitting in fabric, ductwork, or standing air. ONA Liquid is a water-based version of ONA's odor-neutralizing formula, built to run through misting systems and humidifiers or go on as a direct spray, so it keeps working continuously rather than in short bursts.

This 4L Jar (0.86gal) suits keeping a misting system or humidifier running for longer stretches without refilling, suiting a larger room or a facility running the system continuously.

Key Features & Benefits

• Water-based liquid formula — runs through misting systems and humidifiers or applies as a direct spray, unlike the solid form of an ONA Block.
• Multiple application methods — works in misting systems, humidifiers, handheld sprayers, and laundry loads.
• Same neutralizing chemistry as the rest of the ONA line — targets odor-causing compounds rather than covering them with fragrance.
• Fresh Linen scent — a clean, laundry-like residual fragrance.

Who Should Use This

This fits growers and facility staff running a misting system or humidifier for continuous odor treatment, as well as anyone who wants a liquid they can dose into laundry loads or apply with a handheld sprayer rather than relying on a solid block alone.

About Odorchem / ONA

ONA odor neutralizers have been produced by Odorchem Manufacturing Corp on Canada's west coast since 1995, using a formula built to break down odor-causing compounds instead of layering scent over them. The liquid format carries that chemistry into a pourable base suited to misting systems, humidifiers, and direct spray application.

Frequently Asked Questions

How is ONA Liquid different from ONA Gel or ONA Block

ONA Liquid is a water-based, pourable version of the same odor-neutralizing formula used across the ONA line, built to run through misting systems and humidifiers rather than sit as a solid block or gel. That makes it suited to continuous, equipment-based dispersion instead of passive placement.

Can I run ONA Liquid through a misting system

Yes, it's designed to be compatible with standard misting systems and humidifiers, in addition to handheld spray application. Check your equipment's manufacturer guidance on dilution and flow rate before running it continuously.

Can I add ONA Liquid to laundry

Yes, ONA Liquid can be added to laundry loads that need extra odor treatment, particularly fabric that has absorbed persistent grow-room or facility odor. Follow label dosing rather than adding it at full strength.

What size do I need for my misting system

A 1L bottle suits a single misting unit, humidifier, or handheld sprayer running in one room, while a 4L jar holds enough concentrate to keep a system running longer without refilling, which suits a larger room or continuous operation. Match the size to how often you're willing to refill the equipment.
